Two New Mobiles To Peruse

News has been leaked onto the internet about two new Sony Ericsson mobile phones due out later this year. The two phones are the Sony Ericsson G502 and the Sony Ericsson P1 and they should be announced officially by the mobile manufacturer later this week - when more information will be known about the specifications.

First the G502 which by all accounts looks like a pretty standard mobile from Sony Ericsson, much like the K660i that has recently been released. It will be a candybar shaped mobile with a 2 megapixel camera, Bluetooth, 32MB internal memory and 3G / HSDPA.

There is nothing truly spectacular about the Sony Ericsson G502, but that does not necessarily mean it is a poor quality phone. Sony Ericsson mobiles are generally good quality, even the 2 megapixel camera will be of a high standard image on the screen. And the HSDPA should set it apart from a few other mobiles on the market.

Finally there is the Sony Ericsson P5, which is the new smartphone offering from the popular manufacturer. Slightly less is known about this mobile, but what few things we do know are very exciting. The Sony Ericsson P5 is a smartphone with a qwerty keypad hidden under the slide part. It will be a smartphone running off the latest UIQ 3.3 UI for Symbian operating system, with a 5 megapixel camera, Wi-Fi, GPS and HSDPA.

So the P5 really is the one to watch, there is no word on release dates for either of the new Sony Ericsson's - more information will be made available once the phones are officially announced.

All About CDMA

Today there are two major standards for cell phone technology. CDMA and GSM. Almost all phones in the United States operate on either of these networks. However, the average person tends to be unfamiliar with these terms. Common cell phone service providers like Verizon and Sprint use CDMA technology, while carriers like T-Mobile, and Cingular operate on the GSM network.

CDMA stands for Code Division Multiple Access, but was originally known as IS-95. Qualcomm was the first to created this technology and by 1993 it was adopted by the Telecommunication Industry Association. Later this technology was enhanced and refined by Ericsson.

Since the development of CDMA technology there has been many new releases and platforms. The original CDMA is now referred to as CDMAone. Several different variants of CDMA technology been developed continuously improving quality and data transfer speeds. Third generation CDMA technology, commonly referred to as CDMA2000 encompasses a wide variety of different standards, each continually improving upon the first including; 1X EV, 1XEV-DO, and MC 3X. CDMA2000 is the current standard used by most US carriers today. The first release of CDMA2000 was refereed to as either 3G1X, 1XRTT, or 1X. Designed to provide data transmissions of ten times faster then the previous technology and double the voice capacity of CDMAone.

As stated above, Verizon Wireless operates on the CDMA network. Depending on the phone you have and its capabilities you will notice symbols in the default screen of your phone reading either 1X, 1XEV-DO or some variation of the two. This symbol defines the CDMA2000 standards your phone is operating on. Newer phones will display EV or EV-DO using the newer faster, more reliable CDMA technology.

Enhanced data transfer provides for the new technologies released by companies like Verizon. Including data transfer for files, music, games and the Internet.

WCDMA technology, standing for Wideband Code Division Multiple access, is the most developed and advanced form of the third generation CDMA2000 technology. It encompasses higher data transfer rates and provides wireless connections in markets world wide. Many existing GSM 2G (GSM/GPRS) operators have slowly began the switch to using WCDMA technology.

Qualcomm the original developer of CDMA owns patents of this technology. They have granted royalty-bearing licenses to over 100 network operators. The chart below displays the number of operators, vendors, subscribers and countries each technology is used in.

GSM Cell Phones and Their Benefits

GSM world cell phones are the talk of the industry. Many businesses and individuals are looking into this latest technology. So for the novice, what is GSM? Simply put, GSM is a digital cellular technology that is open and can transmit voice and data. Where GSM differs from older technology is that the system divides each channel into eight time-slots which allows the same phone to be used around the world.

Using these cell phones gives you access to the same services on your cell phone whether you are in the United States or Europe or anywhere else there is a signal. You can use the same telephone number and have the same access as you would in your hometown in any of more than 200 hundred countries.

So why is this important? The GSM world cell phones give you the ability to have one phone and travel around the world with it. You do not need to worry about changing SIM cards or other elements of your phone, or have to take the dreaded second cell phone with you.

Travelers like things made as easy as possible. The bane of many travelers' existence has been the need to have two or more cell phones with them when they travel and then try to guess which cell phone will work in which country. This new technology allows you to take only one cell phone with you and have confidence that it will work, including all the features you need, no matter where you travel to.

Sure there are some remote areas where the GSM world cell phone will not work, however, for the vast majority of travelers these cell phones will be the only cell phone they need. It is easy to see why travelers are rejoicing over this new technology. The only thing they have to worry about is having the right electrical adapter to chair their world phone.

As you search online for the best cell phone, you will undoubtedly be impressed with the GSM world cell phones. For anyone who travels out of the country, the practicality of these phones cannot be overstated. Priced right and with a good selection of models to choose from, it is only a matter of time before world cell phones become more popular than traditional cell phones.

The world is a big place but just got a little smaller thanks to the newest technology that has brought us GSM world cell phones.

GSM Cellular Phone

A GSM cellular phone is a type of cellular phone that uses the (G)lobal (S)ystem for (M)obile Communications to send and receive phone calls. GSM is a digital standard; first offered commercially in 1991 and is currently the most popular mobile phone transmission technology in the world.

The GSM standard uses TDMA digital technology, which allows for three different voice calls to be placed in the same time slot, rather than one call using the old analog cellular phones. This is possible through digital compression, which GSM then builds upon with the addition of encryption. A GSM cellular phone takes up the same amount of transmission space as the old technology, but has the additional benefit of added security.

One of the great benefits of a GSM cellular phone is the addition of a SIM card, or "Subscriber Identification Module." This little chip slips into the back of a GSM cellular phone and provides all of the users’ personal information. This includes contacts and calendar information in most cases, and more importantly the subscriber’s personal identification information. Having this information on a removable chip enables a GSM cellular phone user to move a SIM card between cellular phones and still receive voice calls to the same number. It also prevents user from having to re-input personal information each time a new phone is purchased.

GSM Cellular Phone Advantages

A GSM cellular phone offers superior sound quality. Background sounds, disturbances, and static sounds are vastly reduced; and crossed-line conversations are also almost eliminated in a GSM cellular phone. GSM cellular phone sound quality is more like that of a fixed telephone. The main advantages of a GSM cellular phone are International Roaming ability, good sound quality, small affordable handsets and ability to handle a high volume of users. Unlike analog phones, your conversation using a GSM cellular phone within the digital network is safe and secure.

With superior battery life & digital technology of a GSM cellular phone, you get twice as much talk time from each battery charge, compared with analog phones. In addition, the digital service offered by the GSM cellular phone network, allows more calls to be handled at any one time, therefore reducing congestion in areas of dense population and high usage.

A GSM cellular phone offers roaming facility, which means, you can use your GSM cellular phone, with the same phone number in other countries around the world that operate through the GSM cellular phone network or you can just move your SIM card to another GSM cellular phone.

In Europe and most of Asia, GSM is the standard used by everyone. Having one technology is great, because users can simply move their chips to a different GSM cellular phone if they travel to different countries or in most cases use the same phone. This is in contrast to the US, with so many competing standards and difficulty transferring between carriers.

The adoption of GSM technology and GSM cellular phones as a standard also paved the way for the rise of text messaging in many countries. While text messaging is starting to become popular in North America, it is nowhere near as popular as it is in Europe and Asia. Carriers in the US in particular use various technologies in addition to GSM and must then route text messages through third party gateways. This is how a Sprint user can send a text message to a Verizon customer. Until a few years ago this wasn't possible and served to prevent text messaging from truly catching on.

GSM and GSM cellular phones have found a significant boost due to Cingular Wireless becoming America's largest mobile provider. They have adopted GSM technology and promote the GSM cellular phone's ease of use due to a swappable SIM card. Though the US still has many competing technologies, a GSM cellular phone is the international choice. If you plan to travel frequently overseas, a GSM cellular phone might be a wise decision.

The GSM standard has been around for a relatively long time. Its popularity continues to grow because of the addition of GPRS and integration of cameras, MP3 players and other gadgets into a GSM cellular phone. Modern GSM cellular phones support the creation of text and picture messages. Because of these additions, this relatively old standard is actually being phased in within the US.

Dual Sim Mobile Phones

In the Indian phone market the CDMA (Code Division Multiple Access) technology has a fair reach but the GSM (Global System for Mobile communications) or better known as the sim card technology has a preferred appeal.

The CDMA service providers have reduced call rates for their consumers but have an inferior network reach over the GSM technology. Hence dual sim card phones are also designed to support one CDMA network and the other, a GSM network. The dual sim phones in India were first launched by Spice mobile phones. They pioneered in providing a reasonably good handset which used the dual sim technology. They garnered immense popularity for their dual sim phone launch and have been synonymous with this phone technology.

The common drawback of these dual sim phones is the battery life. The switching of the networks reduces the battery life and it is inconvenient for the user to charge the phone every few hours, if you use it extensively. These dual sim mobiles try to pack in the multimedia features but they are not up to the mark. Hence a dual sim phone serves only the purpose of a plain phone supporting 2 networks and the other features are not attractive.

Samsung Mobile also launched a couple of dual sim card phones. They have received appreciation for the ease of operations and the smooth navigation between the networks. The dual sim card mobile phones are very promising and they have a huge potential market. The dual sim card provides for the comfort of using two numbers at the same time. It gives you the ease of switching between networks at your convenience. It also provides with the comfort of attaining calls and messages from both networks simultaneously.
