Okay you’ve seen the ads on TV, but do you know what they actually mean?  Welcome to the "new 4G network" sounds great but what the heck does that mean to me?

Okay, let’s talk about theexisting 3G networks first.

3G comprises several cellular access technologies. The three most common ones as of 2005 are:

• CDMA2000 – based on 2G Code Division Multiple Access
• WCDMA (UMTS) – Wideband Code Division Multiple Access
• TD-SCDMA – Time-division Synchronous Code-division Multiple Access

3G networks have potential transfer speeds of up to 3 Mbps (which is around 15 seconds to download a 3-minute MP3 song). For comparison, the fastest 2G phones can achieve up to 144Kbps (round 8 minutes to download a 3-minute song). 3G’s high data rates are ideal for downloading information from the Internet and sending and receiving large, multimedia files. 3G phones are like mini-laptops and can accommodate broadband applications like video conferencing, receiving streaming video from the Web, sending and receiving faxes and instantly downloading e-mail messages with attachments.

4G is not a technology. It is actually a set of parameters which focus on the use of IP and overall throughput that, once achieved, will enable that platform to be classified as 4G. The open-ended nature of the development cycle sets up a great battle between wireless technologies such as WiMax and post-3G cellular. The interesting thing is that each of these has easily understood advantages and disadvantages: Wireless tends to be cheaper and offer more bandwidth but has a smaller footprint, while cellular is pricier but covers more area.

This blog http://thebestringtonesblog.com details how to download free ring tones, and recommended sites to find the best ring tones. There are a couple of videos detailing sites that list some of the better and comical ring tones that can be downloaded either free or for a small fee. In addition, this site has numerous articles on some of the latest cell phones from Nokia and Verizon, as well as numerous additional articles on polyphonic ring tones, and sites that can be reviewed to download ring tones.

In addition, the process of downloading ring tones is briefly explained, per the following; a ring tone maker allows a user to take a song from their personal music collection, select whatever section of a particular song they especially like and send the file to their cell phone. Files can be sent to a cell phone by direct connection (e.g., USB cable), Bluetooth, text messaging, or e-mail.

Some cell phone providers allow users to create their own music tones, either with a "melody composer" or a sample/loop arranger (such as the MusicDJ in many Sony Ericsson phones). These often use encoding formats only available to one particular phone model or brand. Other formats, such as MIDI or MP3, are often supported; they must be downloaded to the phone before they can be used as a normal ring tone.

Do you every get a call on your cell phone and you wonder who it could be?  Since caller id on your cell phone is only provided by names in your contact list, then the caller who just called will not be displayed if its from someone you do not have in your list.

The number of the phone calling the person is sent to the receiving phone,  the carrier sending the number does have a name in its database but that  is not send with the call.  For this reason, you will need to use a utility such as the reverse cell phone lookup to find out who is calling you..  This way you can find out who has been calling.

Reverse Cell Phone Lookup

Or what if you only have the number and you have already forgotten who that number belongs to? In both of these situations, you can surely find reverse cell phone lookup services to be very useful.

Reverse Cell Phone Search

A  reverse cell phone number search is a neat trick that allows you to find out who the owner is of any phone number. Using a reverse telephone number lookup will provide you with complete information about the owner of the telephone.

Working Of Cell Phones

Cell phones, which operate on radio frequency, cover compartmentalized cell like areas with the help of base stations. Learn more. It’s truly amazing when you think how far we have come in the technology of cellular phones.

Cell phones or cellular phones are so called as they cover compartmentalized, cell like areas. The origin of the Cell phone can be traced back to the year 1973 when Motorola came up with World`s first cellular portable telephone which was commercialised as Motorola DynaTAC 8000X.

These days, new cell phones are being added at a rapid pace. The parts of them typically consist of following: circuit board; antenna; keyboard; LCD – liquid crystal display; battery; microphone; speaker.

In recent times, they are available with a wide range of functions. To list a few functions, depending on the type of cell phone you choose: store contact information; keep track of appointments; set reminders; prepare to-do lists; send/receive e-mail; play games; send text messages (sms); access to internet; watch and enjoy TV; built-in calculator; integration with other devices like GPS receivers, MP3 players, etc.

Cell phones, operating on radio frequency, have come up with an innovative cellular approach to counter limited availability of RF spectrum. Now, several cell phone towers are used to cater to a large geographic area.

Each tower (base station), covers a circular area called a cell. A large region is split into a number of cells allowing different base stations to use the same channels/frequencies for communication. This enables thousands and thousands of mobile telephone users to share far fewer channels.

Another important aspect is that, phones need less power to transmit to reach any base station as each base station covers a smaller area. Reducing the required transmit power reduces the size of the battery and thereby the weight of the phone. This has led to miniaturization of cell phones which would not have been possible without the cellular technology.

When you use your cell phone, following things happen. First the phone locates base station having strongest signal, and requests for a channel assignment. The base station permits channel assignment and the call gets accepted. The call is then forwarded to the local telephone network if it is to a regular phone otherwise it is transmitted through the cellular network. The call is then sent to its destination through the telephone network.

When the cell phone is switched on, SID (System Identification Code) on the control channel compares it to the SID programmed into the phone. If the SIDs match, the phone understands that the cell is communicating with home system. The phone sends a registration request, along with the SID and the MTSO keeps track of the phone`s location in a database. If the SID on the control channel does not match the SID of your phone, then the phone is in roaming.

The three technologies commonly used by 2G cell phone networks for transmitting information: frequency division multiple access (FDMA); time division multiple access (TDMA); code division multiple access (CDMA).

GSM (Global System for Mobile communications) implements TDMA, to connect to the specific service providers in different countries. GSM uses subscriber identification module (SIM). SIM stores all the connection data/identification numbers needed to access a particular wireless service provider.

Standard 2.5G protocols used widely are GPRS, EDGE to name a few. Some latest 3G protocols are: Universal Mobile Telecommunication Service (UMTS); Wideband Code-Division Multiple Access (WCDMA); High-Speed Downlink Packet Access (HSDPA); Evolution Data Maximized (EVDO).

A few popular cell phone models in the market have been offered by Nokia, Ericsson, Motorola, Samsung, LG, etc. with each model with its own range of collections.The year 2008 may be a high watermark in the cell phone history with Nokia N-Gage 2, HTC Dream, Apple iPhone 2, BlackBerry Touchscreen, Sony PlayStation Phone which are expected to be launched.

Mobile Phone Signal Booster

Now that we’re settled in the house, we’ve noticed that our mobile phone reception is quite poor. We both work at home quite often and use our mobiles when we do, so have been looking for a mobile phone signal booster.

First public cell

Cellular phones from the early 1990’s are considered second generation (2G) and they were able to work on mobile phone systems such as GSM, IS-136 (TDMA) and IS-95 (CDMA). Digital mobile phone networks were in use in the United States.

Recent Cell Phone Advancements
 by: Philip Liu 

Cell phones have come a long way since the early days of the 1980s when they were the size of a brick and weighed almost as much. Today, cellular phones come with built-in cameras, polyphonic ringtones, and high-tech games. New 3G mobile phones are also capable of downloading full motion video and full spectrum music. Whereas there were only a few manufacturers of cell phones in the 1980s, today there are many. In addition to original manufacturers such as Motorola and Siemens, today phones are manufactured by Sony-Ericsson, LG, Toshiba, Samsung, Hitachi, Danger, Palm, HP and others.

As wireless cell phone use increases around the globe, the old CDMA and TDMA standards are being replaced with GSM, the global standard outside of North America. Relatively new mobile phone companies such as Vodafone and T-Mobile in Germany and NTT DoCoMo in Japan have taken advantage of increased cell phone use by expanding their mobile phone offerings and plans world-wide. Also, traditional computer companies are moving or have moved into the cell phone industry�PalmOne manufactures the Treo 650, HP is coming out with its own smartphone PDA and Microsoft powers the operating systems of many of the newest cell phones on the market.

In addition to being used as a method of wireless voice communication, cell phones have within the last decade morphed into mobile computing platforms. These new cell phones are powerful enough to power many applications that only a few years ago required one to be stationed at a desktop computer.

Concurrent with technological innovation and increased adoption worldwide, prices for both hardware and service plans have dropped steadily over the last decade. Whereas only a few years ago most cell phone service providers required 3 year contracts with heavy penalties for early cancellation, now one can get a free state-of-the-art phone with only a one year contract.

Beyond the cell phone hardware, whole new industries have sprung up catering to the needs of cell phone users who demand accessories such as cell phone covers, screen-savers, and ring tones. As well, SMS (simple messenging system) and MMS (multimedia messenging system) lingo is slowly entering the cell phone society vernacular. Use of shorthand abbreviations such as LOL (laughing out loud), SWAK (sealed with a kiss) and G2G (got to go) has become second nature to teenagers who are the main users of phone messenging globally.

Gsm Vs Cdma Mobile Technology

GSM and CDMA network technologies are the two main competing technologies set up by cellular service providers across the globe.

GSM is an abbreviation of Global System for Mobile Communications, while CDMA is an abbreviation of Code Division Multiple Access
The technology:

Mobile communication systems have to make use of the microwave frequencies above 800 MHz for transmission and reception of the signals. Different service providers operate in pre allocated frequency bands given to them by the international standards. Below listed are the methods to access these microwave frequencies.

FDMA (Frequency Division Multiple Access) – FDMA puts each call on a separate frequency.

TDMA (Time Division Multiple Access) – TDMA assigns each call a certain portion of time on a designated frequency.

CDMA (Code Division Multiple Access) – CDMA gives a unique code to each call and spreads it over available frequencies.

GSM is a global standard based on TDMA.
How these technologies affect the common man:
In case of GSM:

If you opt for GSM technology, you have the freedom to choose handset separately from the wide variety of big handset companies like Nokia, Motorola, Sony Ericsson, etc who retail their products in the market.

You can then purchase a SIM card from any of the GSM service providers like Hutch, Airtel, etc and insert it in to your handset and start talking.

You even enjoy the freedom to switch the service provider and still continue with the same handset.

GSM service providers are well networked globally. Therefore it offers much better international roaming. You must check for roaming call rates and coverage in the regions or countries where you visit frequently.

Another major benefit that GSM users enjoy is that if you travel to other countries you can make use your same GSM cell phone there too( if it is a quad-band phone 850/900/1800/1900 MHz). To save yourself from roaming charges from your service provider, you can purchase a local SIM card with call value and a local number in the country you are visiting.
In case of CDMA:

Here the handset is network locked. You have to buy a complete package from the service provider that includes both, the handset and the connection (prepaid / postpaid).

Two main CDMA players in India are Reliance and TATA.

Earlier it was difficult for Reliance users who wanted to retain the same number but wanted to change their reliance handsets, to do so. However now it is possible by making use of the handset change card that is available in a nominal amount.

TATA however made it very user friendly. Due to its T – SIM enabled handsets; it is easier for TATA users to change their handsets

Reliance and TATA now have a range of entry level, mid-segment and features rich advance handsets available with them. However in this case the choice of handsets is limited to the models offered by the Service Provider.

You cannot change the service provider and still keep the same handset.

Voice clarity in CDMA network is supposed to be better as it uses same frequency across all cells.

Here you need to check for International roaming tie ups if you travel abroad frequently. You do not enjoy the freedom like GSM mobiles.

TATA is soon launching T-SIM to enable international roaming with one world one number concept.

Before choosing a CDMA or GSM Mobile phone from any mobile store, you need to understand the features and services provided by these mobile phones well

History Of The Cellular Phone

In today’s technologically advanced world, just about everyone has a cellular phone. Adults, teenagers, and even children carry around portable models of the telephone. What is really hard to believe is that just 15 years ago seeing a cellular phone was quite rare.

The history of the cellular phone is very interesting and shows just how the portable wonder became what it is today.

The history of the cell phone begins with a skilled, analytical chemist named Michael Farady. In 1843 he began exhaustive research to find of space could conduct electricity. He told of his findings, and these advances of 19 th century science and technology have had an immeasurable effect on the development of today’s cellular phone.

In 1865 a dentist by the name of Dr. Mahlon Loomis became what is thought to be the first person who was able to communicate wirelessly through the atmosphere. Between the dates of 1866 and 1873 he was able to transmit telegraphic messages 18 miles between the tops of the Cohocton and Beorse Deer Mountains in Virginia.

Loomis developed a way of transmitting and receiving messages by using Earth’s atmosphere as a conductor. He launched kites, enclosed with copper screens, that were linked to the ground with copper wires. He was awarded a $50,000 research grant from Congress to continue his studies.

Fast forward to 1973 when Dr. Martin Cooper became who is thought to be the inventor of the first portable handset. A former general manager fro the systems division of Motorola, Dr. Cooper was also the first person to make a call using a portable cell phone.

He set up a base station in New York with the first working prototype of a cell phone, called the Motorola Dyna-Tac. Both he and Motorola took this technology to New York to show the public.

In 1977 cell phone went public and public testing began. Chicago was the home for the first trials with 2,000 people. Later trials appeared in Washington, D.C. and Baltimore. It spread to Japan in 1979.

Typical technologies changed in 1988 when the Cellular Technology Industry Association, or CTIA, was formed to lay out practical goals for cell phone providers. Included was research for new applications of development.

In 1991 the Telecommunications Industry Association set a new standard with the creation of the TDMA Interim Standard 54.

The history of the cell phone has had quite a long journey. Even though there was a great demand for cell phones, it took a total of 37 years for them to become commercially accessible in the United States.

It’s hard to believe that, since the cell phone has only become popular over the past couple of decades, wireless service was actually invented almost 50 years ago.

According to the CTIA, there are more than 60 million people who own cell phones. Just 25 years ago the cellular business had a $3 million market, while today it has grown to be an industry worth close to $30 billion per year.

Using A Mobile Phone As A Modem For Accessing The Internet

What features and functionality should you understand in order to fully take advantage of accessing the internet via a mobile phone? Although this can appear complicated and involved … a little information goes a long way to "keep it simple".

For the sake of discussion …. let’s say you have a mobile handset with the following specifications:

Networks…

2G Network-GSM 900/1800/1900
3G Network-UMTS 2100

Data…

GPRS- Clause 10(4Ư/3ư slots),32-48 Kbps
3G-384 Kbps

You have configured the software application given with the phone on your laptop …. and once you connect the phone to the laptop using the USB connection you can access Internet. The settings used in the software application includes "call type=GPRS". The connection speed (downlink) is around 375 Kbps when checked through a freely available tool on the Internet …. and the phone’s modem speed is shown as 460.8 Kbps all the time( on the network connection). Since your speed is less than 384 Kbps (3G speed is given as the phone’s spec), you’re likely using 3G. Since GPRS is also supported, when the 3G coverage is not available, you’re probably able switch to GSM/GPRS.

Your service provider says they support EDGE,GPRS,3G and HSDPA/HSUPA.

Here’s some questions you may ask …..

* What are the theoretical maximum speeds of EDGE,GPRS, 3G?

* What is actually meant by 3G here?

* What is the underlaying technology used by my phone?

* Which method is better to connect the phone to the laptop; Bluetooth or USB?

* Your phone spec says Bluetooth v1.2 and USB2.0 and you’ve heard that USB2.0 (480Mbps) is faster than Blootooth v1.2 (1 Mbps). Is this correct? Will it make any difference, since your connection from phone to the Internet is 375 Kbps?

Here’s some feedback to help you work through such a scenario …. and the associated questions above:

For sure, the speed with USB 2.0 should be much better than that through Bluetooth (of any class).

3G is a network technology that should offer some extended data services in addition to the regular GSM features. However, I would recommend that you check with your service providers since they should have the exact specifications that you asked for.

Theoretical speeds for EDGE are up to 10 times those of GPRS. But again, since these depend on network configuration you need to check with the service provider.

Since your speed is less than 1 mb/s, frankly, it doesn’t matter if you use bluetooth or USB – the speeds cited are correct. I would use what is most convenient for you.

In any case, the edge/hsdpa connection speeds are still slower than either Bluetooth or USB, so they will not bottleneck your speed. So as long as your battery isn’t about to run out, you can connect however you choose to.

3G HSUPA is Third Generation High-Speed Uplink Packet Access – a 3G mobile telephony protocol, which offers increased data transfer speeds and capacity of up to 3.6 Mbps on the downlink and up to 1 Mbps on the uplink, under ideal conditions.

3G HSDPA 3.6 is a 3G High-Speed Downlink Packet Access mobile telephony protocol, which offers increased data transfer speeds and capacity of up to 3.6 Mbps on the downlink and up to 348Kbps on the uplink, under ideal conditions.

3G – Third Generation High-Speed Downlink Packet Access – offers increased data transfer speeds and ables customers to access the Internet and email from their cellphones.capacity of up to 1.8 Mbps on the downlink and up to 348Kbps on the uplink

EDGE (Enhanced Data rates for GSM Evolution) or EGPRS provides data transfer rates significantly faster than GPRS or HSCSD. EDGE increases the speed of each timeslot to 48 kbps and allows the use of up to 8 timeslots, giving a maximum data transfer rate of 384 kbps.

HSCSD (High Speed Circuit Switched Data) enables data to be transferred more rapidly than the standard GSM (Circuit Switched Data) system by using multiple channels. The maximum number of timeslots that can be used is four, giving a maximum data transfer rate of 57.6 kbps (or 38.4 kbps on a GSM 900 network). HSCSD is more expensive to use than GPRS, because all four slots are used simultaneously – it does not transmit data in packets. Because of this, HSCSD is not as popular as GPRS and is being replaced by EDGE.

GPRS – General Packet Radio Service is a mobile data service available to customers with GSM cellphones. With a GPRS connection, the phone is "always on" and can transfer data immediately, and at higher speeds: typically 32 – 48 kbps. An additional benefit is that data can be transferred at the same time as making a voice call.

I would recommend using USB as it is faster then Bluetooth. You will not have a bottleneck created by the bluetooth link.

Regarding the underlying technology …

When you phone is connected to a 3G network it will be using W-CDMA (Wideband Code Division Multiple Access) W-CDMA is the higher speed transmission protocol as used in the UMTS system, it is a third generation follow-on to the 2G GSM networks deployed worldwide.

When you phone is on 2G GSM it is using a form of TDMA (time division multiple access).

Again …. the main message is this: Wherever possible, simplify and make it convenient for you!

Texting Abbreviations And A Text Message Primer

It seems today that everywhere you look people are text messaging. Perhaps you just bought as cellular telephone and all you intend to do is talk on it. You are minding your own business when across the screen of your phone is displayed what looks like some foreign language. You look at the screen and look again. Shaking your head, you dismiss the strange combination of letters and numbers as a malfunction with your phone. You put it back in your pocket, but not only does it beep but it also starts to vibrate in your pocket. This is an all to common scenario faced by many people when dealing with new technology and the application of new ways of interaction with something familiar. In this care the combination of telephone (primarily a communication tool used listen and talk) and text. Something you read and respond to by typing. These are two very different means of communicating and either is possible on the modern day cell phone and even, in many cases a landline.

First, a distinction must be made between the two types of converging technologies, that is the landline (common corded telephone or cordless phone with service most often provided by a local phone company) and a cellular telephone which uses radio waves from transmission towers and is more like a radio receiver than a conventional telephone. There are two main types of cellular signal in North America CDMA and GSM/TDMA. This main difference between the two is the way in which each handles the frequency bandwidth. However, a more thorough explanation of Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) will be saved for another article.

Typically, however, people text with cell phones, and assuming you learn how and some of the short form abbreviations that people use when they are "texting", this can be a quick and efficient way to communicate a short, simple message to someone else. Texting is also often called SMS Messaging. SMS stands for Short Message Service. It is text transmitted digitally to other cellular phones. It is called "short" because you are usually limited to 160 characters per message. This has lead to a widespread use of short forms. These acronyms common in computer circles have gone mainstream thanks to the now common and frequent use of text messaging
.
One the most basic of cellular phones, three letters of the 26 in the alphabet are associated with each key and depending upon the number of times a key is pressed, a different letter is displayed. However some more advanced cellular phones make use of a full sized QWERTY keyboard with one key for each letter of the alphabet as well as special letters and symbols.

Now that you have a basic background of text messaging and what it is, lets take a look at some common "initialisms" and define them. A further distinction must be made here between acronym and initialism. The difference between acronyms and shorthand is that with acronyms, you pronounce the letters as a new word. "). In, shorthand, pronunciations are like an initialism (a set of initials) in which you say the letters one-by-one. Below are twelve test message initialisms and their corresponding meanings:

^5 High Five CM Call me GGOH Got to get out of here
2U2 to you to CYT See you tomorrowHAGO Have a good one
A3 Anyplace, Anywhere, Anytime DRIB Don’t read if busyLOL Laugh out loud
BWL Bursting with laughter EG Evil grin TTYL Talk to you later

This short hand is not pronounced together but taken individually. Not only is it letters, but it can be a series of numbers too. Here are a couple of examples:

411 is information
404 means "I have not got a clue"
459 means "I love you"

Not surprisingly the younger generation are more accepting of these conventions, but with texting becoming more and more the norm, those who want to stay informed and want to keep up with the technological convergences between utility and unnecessary convenience make it a point to learn.

An important point must be made here about safety and texting. Because of the distractive nature of cell phones and texting, many states and provinces have made it illegal to talk and text while driving. Even "hands free" implementation of these technologies, although safer, still distract your attention from the road. This has lead to serious accidents and traffic hazards.

While this only covers the basics of text messaging, its beginnings and implications, please find at the end of this articles some clickable resource links where you can learn more and download a reference to common text message shorthand. It does not have to be a confusing garble of letters and numbers. Once learned, text messaging is a quick, efficient and usually unobtrusive way to communicate.

Having said all of the above, there is no substitute for face-to-face open communication with people. Go over to see someone in person and interact verbally and with expressions. It will make a difference in their day that you actually took the time to come over and visit. This will not only make the other person feel better, but you too.

GSM Cellular Phone – 6 Powerful Must Have Benefits GSM Cellular Phones have been around since the early 1990’s. It is only recently that consumers have reaped the benefits of this new technology. Read on to learn more.

By design, the method of transmission for a GSM Cellular Phone is through Global System for Mobile (GSM) communication. Although this system was recognized in the past, it had been first employed on a commercial basis only back in 1991. Nowadays, most of the cell phones throughout the world use the GSM.

Because GSM utilizes the TDMA digital technology, the possibility exists to have up to three voices in one slot in contrast to the analog cell phones where only one voice had the ability to go into one slot. The GSM technology can do so because it utilizes digital compression along with its in-built encryption characteristic. Therefore, even in the event that the space used is the same, there will be more usage capacity.

There are numerous benefits in employing the GSM Cellular Phone for which it owes its amazing global popularity. Some of the most prominent advantages are itemized below:

1. You have the ability to use it as a SIM card – You can get a lot of freedom with the Subscriber Identification Module or the SIM card. You can gather all kinds of information on this chip and then utilize it in whatever other mobile set as and when you change it. The other kinds of sets do not offer this type of freedom to you.

2. Surpassing quality of sound – because the GSM Cellular Phone utilizes technology that is digital in nature, it allows the filtering out of every unnecessary background noises, thus leaving a loud and clear voice transmission for outstanding communication.

3. High Security – There is integrated security for the GSM Cellular Phone that no seperate telephone system has available without specifically requesting it. Therefore, you have the complete assurance that your two way conversation is both safe as well as secure at all time, and at anyplace without costing you any extra money.

International Options

4. It makes available international roaming capabilities – the GSM Cellular Phone can quite easily link up and associate to other international digital providers and thus furnish you with the independence of utilizing your cell phone even when you travel internationally abroad. Although the calls are somewhat costly, customers are happy to utilize this facility because it is hard to communicate to everyone of their new numbers as and while they travel.

5. Extended talk time – the digital technology provides a great deal longer talk time because the battery is utilized in the best practical way. This is additionally increased by the fact one can administer more than one call at any given time.

6. GSM Cellular Phone Extra Options – this kind of cell phone has the ability to incorporate Camera, MP3, FM radio etc., which makes this phone an outstanding entertainment gadget in addition to the useful accessory that it is.
