SMS Text Messaging is very popular, and new technology that increases cell phone bandwidth will make Multimedia Messages the new preferred communications method.

Sending text messages, technically identified as Short Message System (SMS), but also referred to as “texting”, is a uncomplicated, effortless, and convenient manner to communicate to and from cell phones.  Not just a great system for people to correspond, SMS can be a useful means for software programs to exchange simple messages, and even settings commands, to and from  mobile phones.  SMS texting doesn’t need a direct connection between cell phones; the communications infrastructure for the process is already in position, and it works across most cell service providers. One aspect of text messaging that makes it particularly practical for mobile software programs is that it relies on mobile device fixed identity, the phone number. This feature makes available a unique benefit over other technologies that rely on IP addresses because a cell phone IP address will vary depending on current network.

Short Message Service (SMS) is a communication service component of the GSM mobile communication system.  It utilizes uniform communications protocols that allow incoming and outgoing short text messages between smartphones. SMS text messaging is the most widely used data application in the world, with about 2.4 billion active users, or almost 75% of all cell phone subscribers.

SMS texting as used on modern mobile phones was originally defined as part of the Global System for Mobile Communications (GSM) series of protocols in 1985  as a manner of exchanging messages of up to 160 characters, between GSM mobile handsets.  Since the mid-eighties service support has expanded to comprise other mobile technology such as ANSI CDMA networks and Digital AMPS, as well as satellite and landline networks.  The largest number of SMS messages are mobile-to-mobile text messages, though the standard supports other types of broadcast messaging as well.  Computer to mobile device SMS capabilities are also expanding rapidly.

GSM was initially called Groupe Spécial Mobile.  It is the most popular standard for mobile telephone systems around the globe. The GSM Association, the promoting industry organization of mobile phone network providers and manufacturers, estimates that close to 80% of the global mobile market uses the standard.  GSM is enjoyed by over 3 billion people across more than two hundred countries and territories.  Its ubiquity  enables international roaming agreements between mobile phone operators, providing subscribers the benefit of their mobile phones in many parts of the world.  GSM has evolved from its forerunner technologies in that both signaling and speech channels are digital.  Thus GSM is considered a second generation (2G) mobile phone system.  This also  facilitates the wide-spread deployment of data communication programs.

The pervasiveness of GSM deployment can be seen as a benefit for consumers that are given the ability to roam and switch carriers without having to replace their mobile phones, and also to carriers, who can select equipment from a variety of equipment suppliers. GSM is credited with pioneering affordable implementation of SMS texting, which is now supported on other mobile phone standards.

Recent versions of the standard are backward-compatible with the initial GSM system.  Release ’97 of the standard added packet data capabilities by means of General Packet Radio Service (GPRS). Release ’99 introduced higher speed data transmission through Enhanced Data Rates for GSM Evolution (EDGE).

General packet radio service (GPRS) is a packet oriented mobile data service available to users of the 2G and 3G GSM. In 2G systems.  GPRS data transfer is typically billed per megabyte of trafficsent and received, while data transfer using traditional circuit switching is charged per minute of connection time, without consideration of whether or not the user actually is using the capacity or if it is in an idle state. GPRS is a best-effort packet switched service, as opposed to circuit switching, that has assured quality of service during the connection for non-mobile users.

2G cellular systems combined with GPRS are regularly referred to as 2.5G.  2.5G is a technology bridge between the second (2G) and third (3G) generations of smartphone telephony. It delivers moderate-speed data transfer, by using unused time division multiple access (TDMA) channels. Initially there was some thought to broaden GPRS to cover other standards, but these networks are converting to the GSM standard.   GPRS is integrated into GSM Release 97 and newer releases.

GPRS was developed as a GSM response to the earlier CDPD and i-mode packet switched cellular technologies.  Cellular Digital Packet Data (CDPD) was a wide-area mobile data service which used unused bandwidth normally used by AMPS mobile phones.  The service was discontinued in conjunction with the retirement of the parent AMPS service.
CDPD was developed in the early 1990’s, and was seen as a future technology. However, it had competition from existing slower but less expensive Mobitex and DataTac systems.  CDPD never earned widespread acceptance and in time newer, faster standards such as GPRS earned general acceptance and became predominant.

For consumer markets CDPD had little to offer.  AT&T Wireless initially offered the technology in the US under the brandname PocketNet, one of the very first consumer wireless web service offers. Cingular Wireless later offered CDPD under the Wireless Internet brand (as opposed to Wireless Internet Express, Cingular Wireless GPRS/EDGE data). AT&T Wireless PocketNet failed as a product launch.  However, CDPD was used  by some enterprise and government networks.  It was particularly popular as a first-generation wireless data solution for telemetry devices (machine to machine communications) and for public safety mobile data terminals.

Enhanced Data Rates for GSM Evolution (EDGE) (also referred to as Enhanced GPRS (EGPRS), or IMT Single Carrier (IMT-SC), and Enhanced Data Rates for Global Evolution) is a backward-compatible digital smartphone technology that supplies improved data transmission rates on top of standard GSM.  EDGE is considered a 3G radio technology.  EDGE supplies  more than three-fold boost in both the capacity and performance of GSM/GPRS networks by incorporating sophisticated techniques of coding and transmitting data, that deliver higher bit-rates per radio channel.  EDGE delivers broadband performance and supports high bandwidth data applications such as Multimedia Messaging Service (MMS).

A very interesting software application that uses the connectivity between the mobile device  and the internet to capture and archive MMS Multi-Media Messages, GPS location,  SMS messages, and Call Event Logs is PhoneBeagle Mobile Monitoring.  Follow this link if you are interested in    Cell Phone Monitoring Software that works with with BlackBerry  and  Android  Smartphones,.    Visit this link for more information regarding the latest software for  Parental Monitoring and Employee Monitoring of Mobile Phones .

What Sony Ericsson phone should I buy? The choice of a cell phone is easy or difficult depending on how you see the various capabilities included in the majority of the newer designs. Literally speaking, buying a mobile phone has become a pretty challenging task with shoppers addressing specialists in order to be able to understand something from the hi-tech features incorporated in modern design.

In order to be able to determine which Sony Ericsson phone suits your needs, it is a good idea to compare not only features but also price categories as well. Thus, try to learn all sorts of technical details for an item belonging to a certain price group. The internal and external memory, the bluetooth connectivity, the built-in camera and radio, the WAP browser or the GSM modem, represent the elements you should learn about. Moreover, the Sony Ericson phone should match private or business necessities as well, because more capabilities are necessary for different work-related tasks.

The Sony Ericsson phone with an incorporated Walkman has brought a breath of fresh air on the market. This kind of devices are pretty accessible and besides their affordable nature, they also bring excellent music rendering quality. Many market sectors wear the imprint of this innovations, but youngsters have been the first to make this Sony Ericsson phone popular. The battery life is also important for the matter, because the music player or the radio can eat quite a lot of it. Moreover, a sometimes neglected aspect is the importance of being able to transfer data from the phone into a personal computer, and your Sony Ericsson phone needs to match such criteria.

The standard media manager that you may have grown used to on average Sony Ericsson phone models has been replaced by a new version in the recently released designs. There is an XMB media manager for all the Sony Ericsson phone designs that rely on the Java Platform 8 or A200 Platform. With the smart phone generation, another door has been opened towards the future with the use of the Windows Mobile Operating System into the Sony system.

Sony Ericsson W850i is a slider; a cell phone with an innovative design that replaces the older joystick with the five-way scroll key. A large screen and an included Walkman, these are two other hot features that have made Sony Ericsson W850i win the market. While buyers who have an idea of what a phone should be from the technical point of view, make a more serious selection, less informed users are won over by the look of the phone. Available either white or black, this phone seems to give a touch of elegance to the user; the main merit here comes from the 24 carat gold Walkman logo that catches the eye and makes an impression.

We could say that the beauty of Sony Ericsson W850i is not superficial, as it is an overall well built phone. The keypad is modern, featuring a light effect in the form of pulses that follow the music beat. On the inside, the music player is high class, rendering very quality music and an impeccable stereo sound in the FM radio too. The promotional package includes a stereo headset that amplifies the bass frequencies thanks to the incorporated Mega Bass feature. Music lovers really enjoy this mobile device thanks to its 1GB memory stick Pro Duo, which means that the phone can store around 250 tracks and still work well.

The software incorporated in Sony Ericsson W850i makes the management of the device more than user friendly. The drag and drop operation allows an easy and quick file transfer by means of the USB cable. You can also download music directly into the phone thanks to the Walkman software that operates very rapidly. A very smart feature has been introduced in the design: the so-called TrackID. If you listen to a song on the radio but do not know who plays it, this piece of software helps you track the album and the artist. A really incredible feature!

Sony Ericsson W850i has a built in camera that renders very good quality pictures, using both the zoom and the digital flash. The video camera allows one to make 3G video calls or to record. There is no autofocus included in the design, which makes the K800i model superior to Sony Ericsson W850i. Despite this minor flaw, reviews claim that Sony Ericsson W850i makes one of the best Walkman phones ever released. A cheaper non-3G version of Sony Ericsson W850i is also available for anyone interested in getting a bargain. Have a look at both models and see which works best for you!

Sony Ericsson W800i opened the Walkman brand series produced by the company, preparing the market for a different kind of product. The new modern design enhanced the Bluetooth features, USB connectivity and Infrared, all incorporated in a very trendy look. This phone model was released in 2005, and although lots of new features were added to more modern phones ever since, Sony Ericsson W800i is the one that started it all. The external memory has only 2 gigabytes of storage, but we have to consider the period when it was designed and produced. For that moment in particular, such memory size was enough.

There are video recording features incorporated in the Sony Ericsson W800i, the camera has an autofocus and a flash. Moreover, the playback time for the device when operated in the music mode is of thirty hours which definitely means a lot if we consider the life extent of modern batteries. In fact, if the phone is on standby for a longer period of time, then, recharging will only be necessary now and then. According to the specifications, the battery has a 400-hour operational period and a talk time of nine hours. Sony Ericsson W800i can be still purchased from many retailers, and the prices have dropped significantly from the time of the release.

A minor disadvantage of this phone is the fact that it relies on a joystick for memory navigation. Lots of users claim that this is more susceptible to damage and in time functionality problems tend to appear. Sony Ericsson W800i is also very prone to wearing, scratching and minor breaks in time particularly if it is not treated carefully. Sometimes dust may get inside the display ruining the visibility on the screen. Yet, such inconveniences are pretty rare and have not prevented Sony Erricsson W800i from becoming very popular and well sold.

The Chinese imitation known as Music Mobile W800c is the fake variant of Sony Ericsson W800i. There is a striking similarity between the two models, and it is doubtless that the Chinese design pays tribute to the W800i series. The quality of this fake model is doubtful and Sony Ericsson W800i in its original variant is definitely superior. Should you come across this item while searching for a good mobile, it is advisable to consider more than just the price tag before getting it. Otherwise, you may waste your money on a poor mobile device that can fail you any moment!
