Cell Phone Safety Issues - From Driving to Tracking Down Unknown Numbers

The old saying, "with great power comes great responsibility," may seem a little dramatic for a cell phone, but experts would tell you a different story. For every situation that a cell phone can assist you in with work, family, or your personal life, there is another that can also potentially put you in danger. Though there are many ways that cell phones can pose a risk to you and your family, you can help protect them by simply being aware of the dangers and tracking down unknown numbers using reverse phone lookups.

There are a couple major risks for cell phone users. First, a cell phone can be a physical threat to you if you are using it while driving. Study after study has shown that not only are people who drive and talk more likely to get into a wreck, but they are four times more likely to get into a wreck involving injuries. Driving and talking on a cell phone not only takes your eyes off of the road but also disrupts your concentration. While hands-free sets are becoming more popular, studies have shown that the only way to truly eliminate the distractions of a cell phone while driving is to not use one on the road.

The second threat is more subtle, however. Though not necessarily a physical harm, pranksters can use a cell phone to make harassing (or even threatening) phone calls. This can cause great stress for your family and run up your phone bill, but you can put an end to such calls by using a reverse phone lookup to find out the name and number a prankster uses. While telemarketing companies can use cell phones to help mask their identity, there are some reverse phone lookups that search private directories for mobile numbers.

The only way to counter these dangers is to properly defend oneself, and the best defense is to be armed with tools. The most valuable tool to protect yourself against unknown callers is the reverse phone lookup. No matter what the issue -- cell phones and driving or unknown callers -- the first step to prevention is staying informed.

Privacy Issues Surrounding Forward Cell Phone Directories

Everyone has been thankful for the telephone book white pages at one point or another. Being able to look up individuals' telephone numbers is a convenience that many of us have grown up with, but with the rise of cell phones, it may soon be a thing of the past. Today if you want to know someone's telephone number, and they have a cell phone, you are out of luck. Forward cell phone directories do not exist.

You may know you can use a reverse cell phone lookup to find out who has been calling you. By searching for mysterious numbers, reverse cell phone lookups provide the name and address of mysterious phone numbers. Incoming calls to your cellular phone can cost money or simply become an annoyance. Reverse cell phone lookups can help people who are being harassed to identify the offender and pursue a course of corrective action. This makes reverse cell phone lookups a great way to protect your privacy by helping you keep track of who's been calling you. With this one hundred percent legal tool, you can make sure you're protected.

On the other hand, forward cell phone directories do not exist because they are illegal and invasive to privacy. This is because cell phones are still considered to be private lines. Listing someone's cell phone number in a public directory is considered a criminal invasion of privacy. If you find a site that advertises a forward cell phone directory, you should be highly suspect of any information they provide you. Frequently internet sites that offer impossible services are fronts for identity thieves and computer hackers.

Though our privacy is under constant assault, using a reverse phone lookup can help make sure that you're in charge of your phone line and who calls you. Phone research and lookup legality are hot topics in today's world. Be sure to keep checking the internet for more information as it becomes available.

Calling All Kids - Cell Phones For You

Cell phones aren’t just for adults anymore. Cell phones exist for kids that are simple, sturdy and look like toys. Other phones look like regular cell phones, but have features that appeal to kids. Maybe most important though, these phones have features that appeal to parents.

Phones With Parent Appeal Parents everywhere have reasons to buy cell phones for their kids. Maybe your youngster has been begging you for a phone after seeing that all their friends have them. They might even make the case that they need one to stay in touch with you or contact you in an emergency. Parents imagine a big mess: huge phone bills and strange numbers on the phone. Yet, many parents are finding ways to get around steep phone bills and unnecessary conversations. Some companies make phones specifically designed for kids with features parents will love. Here are four popular types of cell phones for kids today with built-in features parents appreciate.

Disney Mobile

• Allows parents to set monthly spending limits for their children’s phones through the phone or the computer. Once a child reaches the limits, they are still allowed to make and receive calls to designated numbers and can still get through to 911. Parents are alerted once a child reaches their limits and may raise them.

• Parents can program the days and times during the week when children can use the phone and can track the location of the phone from their own phone or computer.

• Parents can also enter phone numbers that their children can never access.

Firefly phone

• Using a parental pin, parents can add up to 20 numbers.

• The call screening feature on the phone rejects calls not stored in the Phone Book.

TicTalk phone

• Parents can visit MyTicTalk.com to set controls on the phone. Controls include entering phone numbers that can be called anytime, calling numbers that only can be called during permission-based times which parents set, selecting what times phones can ring, sending your child a reminder, and choosing which features to enable or disable.

• And what’s better than a phone that encourages learning? Kids can earn extra minute rewards on TicTalk phones for playing LeapFrog learning games on their phone.

Verizon Migo

• The phone comes with an optional Chaperon service, where parents can track the phone in real time on their own phone or computer.

• Parents can pay an additional charge to set boundaries for their child; for instance, if their kids leave a designated area, parents will get a text message sent to their phones.

A phone for kids is worthless though if your child won’t use it. Let’s take a look at each of the above phones and why your kids might like their features. Here’s more information on these phones specifically designed for kids.

Disney Mobile, a phone specifically designed for 10-15 year olds includes custom text messaging as well as preset text messaging choices such as “Can U Get A Ride?” Kids can connect to Radio Disney as well as download wallpaper, graphics, and ringtones from Disney. TicTalk phones allow kids to record their own ringtones and download photos. A calendar and to-do list are also available on the TicTalk phone.

But what good are lots of cool features if they are too complicated for your kids to use? Simplicity is particularly key on the Firefly and Verizon Migo phones, which are designed for younger children. The Firefly simplifies things with only five keys. The Verizon Migo, designed for kids between five and nine years old, has five speed dial buttons on the front that parents can program for their kids.

Service Plan Options Interested to know how much these phones cost? In most cases, the phones themselves are more expensive than regular cell phones.

• Customers sign contracts with Disney but the service is actually on Sprint’s network. Interested customers can visit DisneyMobile.com. The Disney service works with LG phones ($110 each) and Pantech phones ($60 each). Subscribers to the Disney service buy two or more phones. One person with the “parent” phone becomes the “family manager” and sets monthly spending allowances for the “child” phone by accessing the Family Center menu on the phone. The monthly family phone plan with two lines and 450 daytime minutes starts at $59.99.

• TicTalk phones can be purchased online at http://www.enfora.com

Rate plans are prepaid according to phone minutes. For example, $25 for 100 airtime minutes.

• A Firefly phone costs $79.99 and includes a travel charger, backpack clip, and 30 minutes of airtime. Firefly has a monthly package starting at $9.99 and a pay-as-you-go $.25 per minute package that requires a minimum of $25. Both can be cancelled at any time.

• The Verizon Migo phone costs about $120 and calling plans vary.

Parents should check out these phones and plans if considering a wireless device for their young children. Kids will probably find the phones easier to use than standard cell phones and parents have the control and peace of mind that they desire.

How to Block Your Cell Phone Number When Calling Someone

There may be times when you don't want the person you are calling to see your phone number. Reasons why you may want to conceal your cell number include:

• You don't want the person you are calling to see that you've called them 10 times in a row.

• You don't know the person you are calling and don't want them to have access to your number.

• You are calling a business or an unknown number and don't want them to know your number.

If you decide that you would like to keep your cell phone number a secret, you will need to block your number. Blocking your number can be done temporarily or permanently. Temporarily blocking your number on a call by call basis is a good idea if there are only a few people whom you wish to hide your number from. To temporarily block your number so it is not displayed on the recipients caller ID simply dial *67 before dialing the number (I.E. *67 111-111-1111).

Keep in mind, you should know that when you use *67 to temporarily block your number there will be nothing to inform you that your number has been successfully blocked. Therefore, if you want to make sure it works, do a quick check and call your home number first before you attempt to use this service on someone else.

If you really want your cell number to be private, and wish to block your mobile phone number permanently, you will need to contact your wireless provider and request a "line block". Once the line block has been established, your number will not appear to anyone. However, if, for some reason, you would like your phone number to be displayed for the recipient, you can reveal your phone number by dialing *82 before dialing their phone number.

Finally, you need to know is that your cell phone number will not be blocked from any toll free numbers (I.E. 800 numbers), or from emergency services.
In addition, blocking your cell phone number may be a good idea if you are attempting to find out who owns a phone number by calling the mystery number back.

How to Trace a Cell Phone Location

New advances in technology have made it possible for anybody to trace a cell phone location.
These advances in technology designed to trace a cell phone location came about as a result of a number of recent events, including the events of September 11, 2001. Technological breakthroughs which have occurred since then include the inclusion of GPS technology in most mobile phones, and an improved ability to detect a phone's location based on signals from local transmission towers.

There are number services on the Internet which allow you to trace the location of a cell phone. They may differ in therms of interface and appearance, butthey are using the same data from the telecom companies.

In the past the only way to gain access to the technology to trace a cell phone location was to buy equipment, and the use of this equipment was largely regulated to official organisations such as the police.

The way these services work is by gathering information from the telecom company that provides the cell phone service. this information includes the location of the cell phone as calculated by a combination of factors including the GPS as previously mentioned, and the distance to each of the nearest cellphone transmission masts. This is the same information which the police get.

There are wide range of reasons why you might want to trace a cell phone location, such as trying to find out where a friend or relative rates while you're out and about, keeping track of the location of a child, meeting up with friends, and trying to find shops and restaurants near you. Companies make use of these services in order to track their employees location, and also to provide security for employees when they are working in a remote location on their own. In the end, there are probably as many reasons as there are users.

The way GPS technology works in modern cell phones varies between the different cellphone networks, and with some operators it does not continuously transmit location. This means that when you want to trace a cell phone location, the information that you will be gathering is most likely collected from transmission tower locations.

The location of the phone will be tracked using triangulation - by taking 2 or more readings, it is possible to calculate where the signal is comming from by working out the triangle that fits the signal strengths. The 3rd point is the location of the phone.

However, when the person who has the phone has made an emergency call, this GPS transmission will always be sent. This is designed to ensure that the police can always track a cell phone location, in order to get help to people who need it.

The result of this design that the accuracy of the location which is provided by the service will be greater in areas which are more populated, and have more radio transmission masts, and will be lower in areas where there are very few radio masts, such is the wastelands, deserts, or un-populated areas of countryside. So, it is easier to track a cell phone location with a high level of accuracy in built up areas.

Nonetheless, most times you trace a cell phone location the information from the cell phone masts should be fine. After all, you do not need to know the person's location with a very great deal of accuracy for most purposes.

Matthew Burns is the author of Internet Guider. He has published a guide to cell phone search resources to help you locate cell phone numbers on the Internet.

Mobile Inner Decoration

There are three main components of mobile inner decoration.
1. Mobile Wallpapers
2. Mobile Screensavers
3. Mobile Themes

1. Mobile Wallpapers

Let's start with wallpapers. Each and every mobile phone has this option, either new or old. Like desktop wallpapers, mobile wallpapers are stilled images which can be set as background of the mobile screen. Some mobile manufacturers provide options for animated wallpapers too to be used as background in mobile phones. Large numbers of varieties are available for mobile wallpapers; either you talk in size or in category.

2. Mobile Screensavers

After mobile wallpapers here comes the mobile screensavers. Not all but many mobile phones have this option. Mobile screensavers are animated images consists of set of different images. These screensavers displayed when you leave your mobile phone screen still for a long time.

3. Mobile Themes

Finally after mobile wallpapers and mobile screensavers we have mobile themes. Many mobile phones have option of themes available. Mobile themes are set of images and colors which are used on different places in mobile phone. Color combination remains same but images may vary in different sections of mobile phone. Some themes consist of only two images; one image is used as main wallpaper while the other one is used for navigation.

Hope you will find this article informative for the cause of inner decoration of your mobile phone. You can find wallpapers, screensavers and themes for your mobile phones very easily on web.

Trace Mobile Number

There are many reasons why you may need to trace a mobile number.

If you're in business, you may have missed a call and need to know who it was that was calling you. Otherwise that next lead or deal could stay forever lost.

Perhaps a missed call number seems unfamiliar to you but you haven't heard from an old friend for a long time. Could it have been them?

Are your children receiving unwanted calls and possibly being tormented by bullies via their mobile phone? Tracing that nuisance mobile number could put a stop to all that.

Indeed, are you being plagued by prank calls? Wouldn't you like to put a stop to them too?

Finally, do you have your suspicions about a partner receiving calls from their secret lover and you'd like to find out once and for all what's going on and with whom?

All of this annoyance could be ended by simply tracing that mobile number. What you need to do is a reverse mobile phone look up. As it suggests, you are literally looking up that mobile number that rang you.

From doing so you can expect to find out the following about whoever rang you:

Their name

Their address

A previous address

Details about their relatives

Details about their neighbours

Not all sites offer all of the above information, but you will at least always discover their name and address.

Just think how helpful that would be to you, your business, your children's safety & the security of your relationship.

All you have to do is sign up as a member on one of these excellent sites.
It does cost a little, as these mobile numbers are not out there in the public domain and the directories have to be manually assembled which takes a lot of man hours. Plus, of course they are regularly updated so that you're never let down or disappointed when you do a search.

Once you are signed up as a member you can make an unlimited number of searches in order to gain that much needed knowledge & ultimate peace of mind.

The searches literally take seconds and if you don't receive a result, then you don't have to pay. You can't get better than that, can you?

Any how, don't just take my word for it. Try the best one I've found out there, for yourself by taking a look at my bio box.

Hopefully, you can get your life back and rest easier now knowing how easy it is to trace a mobile number.

See what you're missing when it comes to reverse phone look ups, you'll be surprised what you can find out from my blog http://freereversecellphonelookup.blogspot.com/

Google wants to store all your files

The Wall Street Journal reports that the company is preparing a service that would let users store on its computers essentially all of the files they might keep on their personal computers, such as word processing documents, digital music, video clips and images.

Users could access their files via the Internet from different computers and mobile devices when they sign on with a password, and share them online with friends.

“A document Google inadvertently released on the Web in March 2006 said it was moving toward being able to “store 100% of user data,” citing “emails, Web history, pictures, bookmarks” as a few examples. The document referred to what appeared to be unannounced Google initiatives, including one dubbed “ GDrive ” and said they could help compete with Microsoft.”

Some of the storage space would be free, with additional storage allotments available for a fee. It could be released as early as a few months from now, according to some leaky people who declined to share their names.

Google already does some of this through its existing Web applications, but this service would tie everything together with a single search box. Other companies offer various Internet-based file storage services, but most have been slow to catch on. Some, like Yahoo's Briefcase, require users to go to a Web page and click through a few screens to upload a new file and set various limits.

Google's grand vision faces many bumps, most alarmingly of the privacy variety. No word yet on whether the search giant plans to display ads as part of the storage service, as it does with Gmail, which would likely raise red flags for privacy groups.

Even if it doesn't, consumers receive a lesser level of legal protection for the privacy of their data when it is on an Internet-based file storage system as opposed to just on their own computers, according to Kevin Bankston, staff attorney at the Electronic Frontier Foundation.

Mobile Phones - A New Age Phone For a New Age Gamer

The brand new Sony Ericsson has been launched and combines modern technology used in mobile phones and gaming stations such as the Nintendo Wii. The Sony Ericsson F305 is aimed at computer games fans. The phone will allow users to play games in a different way as users will be able to flick their wrists or swing an arm to play games. The games will include Bowling, Bass Fishing and Jockey with further games available to download.

The two biggest technological products around are games consoles and mobile phones so it is only logical that someone was going to combine both. It is a brave step to take as they have invested a considerable amount of money into the project and is similar to their introduction of the Walkman mobile phone to compete with the Apple iPod.

Our mobile phones play an important part of our lives and this new invention is to maybe to persuade users to take a break from our every day lives and play a game. The phone is designed to encourage interaction with other people and bring the gaming world to you when you most need it.
Recommended retail price is yet to be confirmed but if you opt for pay as you go mobile phones you are likely to pay considerably more than if you chose a monthly contract. The handset will also include extras such as speakers, games controls and a battery that will last up to 8 hours and if you get over zealous bowling the night away there will be a power pack supplied in case of emergency.

You will soon be able to find all the latest phones online and it is here where you should look for the best mobile phone deals by comparing the different providers and their offers.
The brand new Sony Ericsson is the latest in new technological mobile phones. You are sure to pay more if you choose pay as you go mobile phones so make sure you search for the best mobile phone deals online and start your mobile gaming experience.

Wii Mobile

By John Gray

The Sony Ericsson F305 has just been officially announced from the popular mobile manufacturer. This is a mobile that is not centred around a camera, walkman music player or GPS like most new mobile phones - but instead is aimed at the gamers among you. And it takes it's gaming theory from the Nintendo Wii and its clever and enjoyable Wiimotes.

The Sony Ericsson F305 comes with three games pre-installed (Bowling, Bass Fishing and Jockey) which are all intended to show off the motion sensor on the mobile. The games can be played by using the phone like the Nintendo Wii controllers - moving them around to control what is on screen as opposed to pressing buttons. While this does sound like a lot of fun, and indeed the Nintendo Wii has proved to be very popular, it seems like there is a flaw in the concept! While you are able to control the game by moving the phone, it will of course limit your view of the screen as the phone will now be in motion away from you! However only the actual playing will be proof of the pudding. And I imagine that insurance is essential with this mobile - as gaming accidents with mobile 'flying out of hands' could prove costly.

As well as the gaming aspect the Sony Ericsson F305 has pretty average features such as a 2 megapixel camera, multimedia player, FM radio and expandable memory. While it is not a bad phone, Sony Ericsson tend to make very few of those, it is not really outstanding in any area. While the gaming aspect is quite clever the small 2.4 inch screen and limited resolution will probably not propel it into stardom.

However, if gaming is your thing then look out for the Sony Ericsson F305 in late summer.

Evolution of the Mobile Technology

"If you can dream it, you can do it", according to this we can leap 3G to 4G along its features and future trends in mobile technology. In wireless communication, mobile technology is advanced and in this system 4G is the latest at present.

The article discusses 4th generation. 4G mobile, aims to provide an effective solution for the next generation mobile services. Progressing from previous three generations, 4G mobile systems have been significantly improving in terms of interactive multimedia services:

The first radiotelephone service was introduced in the US at the end of the 1940s, and was meant to connect mobile users in cars to the public fixed network. In the 1960s, a new system launched by Bell Systems, called Improved Mobile Telephone Service" (IMTS), brought many improvements like direct dialing and higher bandwidth. The first analog cellular systems were based on IMTS and developed in the late 1960s and early 1970s. The systems were "cellular" because coverage areas were split into smaller areas or "cells", each of which is served by a low power transmitter and receiver.

First generation:-
1G analog system for mobile communications saw two key improvements during the 1970s: the invention of the microprocessor and the digitization of the control link between the mobilephone and the cell site. AMPS ( Advance mobile phone system ) was first launched by US which is 1G mobile system. It is best on FDMA technology which allows users to make voice calls within one country.

Second generation:-

2G digital cellular systems were first developed at the end of the 1980s. These systems digitized not only the control link but also the voice signal. The new system provided better quality and higher capacity at lower cost to consumers. GSM (Global system for mobile communication) was the first commercially operated digital cellular system which is based on TDMA.

Third generation:-

3G systems promise faster communications services, including voice, fax and Internet, anytime and anywhere with seamless global roaming. ITU’s IMT-2000 global standard for 3G has opened the way to enabling innovative applications and services (e.g. multimedia entertainment, infotainment and location-based services, among others). The first 3G network was deployed in Japan in 2001. 2.5G networks, such as GPRS (Global Packet Radio Service) are already available in some parts of Europe.
3G technology supports 144 Kbps bandwidth, with high speed movement (e.g. vehicles), 384 Kbps (e.g. on campus) & 2 Mbps for stationary (e.g.inbuilding )

Fourth generation:-

At present the download speed for mode data is limited to 9.6 kbit/sec which is about 6 times slower than an ISDN (Integrated services digital network) fixed line connection. Recently, with 504i handsets the download data rate was increased 3-fold to 28.8kbps. However, in actual use the data rates are usually slower, especially in crowded areas, or when the network is "congested". For third generation mobile (3G, FOMA) data rates are 384 kbps (download) maximum, typically around 200kbps, and 64kbps upload since spring 2001. Fourth generation (4G) mobile communications will have higher data transmission rates than 3G. 4G mobile data transmission rates are planned to be up to 20 megabits per second.

Before understanding 4G, we must know what is 3G ? 3G initiative came from device manufactures, not from operators. In 1996 the development was initiated by Nippon Telephone & Telegraph (NTT) and Ericsson; in 1997 the Telecommunications Industry Association (TIA) in the USA chose CDMA as a technology for 3G; in 1998 the European Telecommunications Standards Institute (ETSI) did the same thing; and finally, in 1998 wideband CDMA (W-CDMA) and cdma2000 were adopted for the Universal Mobile Telecommunications System (UMTS).

W-CDMA and CDMA 2000 are two major proposals for 3G. In this CDMA the information bearing signal is multiplied with another faster ate, wider bandwidth digital signal that may carry a unique orthogonal code. W-CDMA uses dedicated time division multiplexing (TDM) whereby channel estimation information is collected from another signal stream. CDMA 2000 uses common code division multiplexing (CDM) whereby channel estimation information can be collected with the signal stream.

Access Technologies (FDMA, TDMA, CDMA) -
FDMA: Frequency Division Multiple Access (FDMA) is the most common analog system. It is a technique whereby spectrum is divided up into frequencies and then assigned to users. With FDMA, only one subscriber at any given time is assigned to a channel. The channel therefore is closed to other conversations until the initial call is finished, or until it is handed-off to a different channel. A "full-duplex" FDMA transmission requires two channels, one for transmitting and the other for receiving. FDMA has been used for first generation analog systems.

TDMA: Time Division Multiple Access (TDMA) improves spectrum capacity by splitting each frequency into time slots. TDMA allows each user to access the entire radio frequency channel for the short period of a call. Other users share this same frequency channel at different time slots. The base station continually switches from user to user on the channel. TDMA is the dominant technology for the second generation mobile cellular networks.

CDMA: Code Division Multiple Access is based on "spread" spectrum technology. Since it is suitable for encrypted transmissions, it has long been used for military purposes. CDMA increases spectrum capacity by allowing all users to occupy all channels at the same time. Transmissions are spread over the whole radio band, and each voice or data call are assigned a unique code to differentiate from the other calls carried over the same spectrum. CDMA allows for a " soft hand-off" , which means that terminals can communicate with several base stations at the same time.

Beyond 3G

In the field of mobile communication services, the 4G mobile services are the advanced version of the 3G mobile communication services. The 4G mobile communication services are expected to provide broadband, large capacity, high speed data transmission, providing users with high quality color video images, 3D graphic animation games, audio services in 5.1 channels. We have been researching the vision of 4G mobile communication systems, services, and architectures. We also have been developing the terminal protocol technology for high capacity, high speed packet services, public software platform technology that enables downloading application programs, multimode radio access platform technology, and high quality media coding technology over mobile networks.

Reasons To Have 4G -
1.Support interactive multimedia services: teleconferencing, wireless Internet, etc.
2.Wider bandwidths, higher bit rates.
3.Global mobility and service portability.
4.Low cost.
5.Scalability of mobile networks.

Mobile phones : more risky than smoking and asbestos

Research undertaken by Dr Vini Khurana, has shed new light on the dangers, and takes the view that prolonged mobile phone use could kill more people over time than smoking or asbestos.

There have been mixed messages about the possible dangers of mobile phone use. Clinical studies have on occasion produced contradictory findings, making it difficult for mobile phone users to arrive at a realistic assessment of the risks. Research undertaken by Dr Vini Khurana, has shed new light on the dangers, and takes the view that prolonged mobile phone use could kill more people over time than smoking or asbestos.

Professor Khurana is a top neurosurgeon with many awards to his name. He has reviewed more than 100 studies on the effects of mobile phone use. Recently he placed the results of his research on a brain surgery website - www.brain-surgery-us. He cites a body of evidence that demonstrates a link between mobile phone use and brain tumors. Professor Khurana believes the use of a handset for 10 years or more could double the risk of a brain tumor.

A number of clinical studies have made a connection between mobile phone use and brain tumors. One of the best known is a study by Swedish oncologist and cancer epidemiologist, Lennart Hardell. The Hardell research indicated that - " ...use of mobile phones for 10 or more years give a consistent pattern of increased risk for acoustic neuroma and glioma. The risk is higher for ipsilateral exposure (i.e., cell phone use preferentially on the same side as the eventually diagnosed brain tumor)."

Mobile phone technology is something users tend to take for granted. The importance of mobile phones in emergency situations is an obvious plus. The potential hazards of placing a gadget to the side of the head that emits radio waves, is a secondary concern for most. The power generated by a handset fluctuates. Adaptive power control (APC), takes place on a continual basis and can go from a high of 2 watts to as low as 1 milliW. The selected power level depends on a number of factors such as distance from the base station, presence of tall buildings or other physical obstacles, and whether the handset is being used indoors or outdoors.

The effects of mobile phone radiation on human tissue can be classified as both "thermal" and "non-thermal." Thermal reactions occur when tissues are heated. This heating effect can cause molecular changes within cells, possibly leading to the cancerous transformation of the cell. Non-thermal effects occur over time and are connected with "pulsing" of the carrier signal. Studies have linked non-thermal exposure with DNA damage. In a section of his research titled "emerging concepts and concerns", Professor Khurana offers useful insights and advice on mobile phone use.

He points out that there is a growing body of evidence that brain tumors, such as vestibular Schwannoma and astrocytoma are associated with "heavy" and "prolonged" mobile phone use. Moreover these conditions tend to occur on the side of the head exposed to the mobile phone. He has taken the additional step of issuing a warning that reflects the level of his concern about the growing evidence of the impact of mobile phone use on health:

"... unless the Industry and Governments take immediate and decisive steps to openly acknowledge and intervene in this situation, even while waiting definitive confirmation by large and well-constructed multi-centre studies worldwide, malignant brain tumour incidence and its associated death rate will be observed globally to rise within a decade from now, by which time it may be far too late to meaningfully intervene, especially for those who are currently children and young adults."

In a list of cautions, the professor recommends keeping mobile phone use down to a minimum. When using a mobile, he suggests increasing the physical distance between the device and the side of the head, by using "speaker mode" or "hands-free mode." Avoid turning the head into a "mobile antenna" by reducing use of Bluetooth devices and unshielded wire earphones. Finally he urges that the use of mobile phones by children should be restricted to emergency situations.

Free Reverse Cell Phone Look Up

Wouldn't it be great if you could get a free reverse cell phone look up?

Maybe, sometime in the not too distant future this may actually be possible but for now it can't truly be offered.

There are many many sites on the web that do offer free reverse phone look ups, but these only cater to landline phones.

So why do they exist but the same isn't possible for cell phones?

Simply, because all the landline numbers are in the public domain and so are obtainable by anyone. (Unless you are un-listed or not published)

Cell phone numbers, however, are not easily obtainable and the directories that are produced for all the cell phone numbers that exist are huge, time-consuming to assemble and costly to produce.

That is why the only reliable and guaranteed reverse cell phone look up sites are those that require you to sign up as a member for a very small fee. They have to cover their costs.

Any sites that offer the same for free are more than likely not legitimate or are working from very outdated or incomplete lists.

Why waste your time and effort searching on all of these free sites in order to gain nothing?

In mine and many others experience it pays to join a reputable site in order to get speedy correct information.

All you have to do is enter the cell phone number you want to trace, click search and seconds later you'll receive at least that person's name & address. Often a lot more too.

Once you're a member you can make as many searches as you like for no extra cost & if they can't produce a result for you, you don't have to pay your membership. I like those odds.

So, do yourself a favour and appreciate that there's no such thing as a free reverse cell phone look up.

How to Trace a Cell Phone Location

New advances in technology have made it possible for anybody to trace a cell phone location.

These advances in technology designed to trace a cell phone location came about as a result of a number of recent events, including the events of September 11, 2001. Technological breakthroughs which have occurred since then include the inclusion of GPS technology in most mobile phones, and an improved ability to detect a phone's location based on signals from local transmission towers.

There are number services on the Internet which allow you to trace the location of a cell phone. They may differ in therms of interface and appearance, butthey are using the same data from the telecom companies.

In the past the only way to gain access to the technology to trace a cell phone location was to buy equipment, and the use of this equipment was largely regulated to official organisations such as the police.

The way these services work is by gathering information from the telecom company that provides the cell phone service. this information includes the location of the cell phone as calculated by a combination of factors including the GPS as previously mentioned, and the distance to each of the nearest cellphone transmission masts. This is the same information which the police get.

There are wide range of reasons why you might want to trace a cell phone location, such as trying to find out where a friend or relative rates while you're out and about, keeping track of the location of a child, meeting up with friends, and trying to find shops and restaurants near you. Companies make use of these services in order to track their employees location, and also to provide security for employees when they are working in a remote location on their own. In the end, there are probably as many reasons as there are users.

The way GPS technology works in modern cell phones varies between the different cellphone networks, and with some operators it does not continuously transmit location. This means that when you want to trace a cell phone location, the information that you will be gathering is most likely collected from transmission tower locations.

The location of the phone will be tracked using triangulation - by taking 2 or more readings, it is possible to calculate where the signal is comming from by working out the triangle that fits the signal strengths. The 3rd point is the location of the phone.

However, when the person who has the phone has made an emergency call, this GPS transmission will always be sent. This is designed to ensure that the police can always track a cell phone location, in order to get help to people who need it.

The result of this design that the accuracy of the location which is provided by the service will be greater in areas which are more populated, and have more radio transmission masts, and will be lower in areas where there are very few radio masts, such is the wastelands, deserts, or un-populated areas of countryside. So, it is easier to track a cell phone location with a high level of accuracy in built up areas.

Nonetheless, most times you trace a cell phone location the information from the cell phone masts should be fine. After all, you do not need to know the person's location with a very great deal of accuracy for most purposes.
