A reading of major tech blogs on the Internet, Mobile Magazine, inevitably lead to at least a handful of tickets drooling over the 3G mobile phone with all the drooling over the latest offer from the 3G mobile phone manufacturers in Korea, Japan and elsewhere.
The current technology :
Generall
y, most mobile phones on the market today a part of second generation or "2G". This includes standards such as GSM (Global System for Mobile Communications: As the services offered by T-Mobile) and back (Integrated Digital Enhanced Network: developed by Motorola and deployed by Sprint / Nextel).
Multiple phones and networks are also capable of data faster than conventional 2G technology. These are often mentioned as a part of 2.5G or 2.75G. The most common 2.5G technology is GPRS, or General Packet Radio Service, working with GSM networks. Further along the spectrum are technologies such as CDMA2000 1xRTT (1 times Radio Transmission Technology) and EDGE (Enhanced Data Rates for GSM Evolution). Each of the subsequent generations have provided data faster and faster transfer speeds to keep up with high demand services such as picture messaging, downloading ring tones, and mobile web.
3G Deal :
3G mobile technology is said to be a leap forward in data transfer to mobile phones, and as people demand more and more full of content, networks must stay mobile and send data faster than ever.
Video Telephony :
The video is said to be the "killer application" for 3G. As such, many 3G phones are not one but two cameras. The "principal" of the camera is typically on the back of the phone and a megapixel (or better) picture taker. Search for phones with 2 megapixel camera or better is no longer unusual, and some devices offer up to 8 megapixels. The "secondary" camera, but are usually beside the VGA display and a single unit. This is intended to be used for video calls. But in areas where 3G is more prevalent, like urban regions in
Mobile TV and web :
For more information about mobile television, see the official mobile TV here in Encyclopedia phones. Although mobile TV is technically a separate issue of 3G mobile telephony, the two often discussed in the same breath. Often, users download video clips of short duration, and even download movies with 3G technology, especially when the "traditional" mobile TV - including T-DMB - not available.
Ringtones, music and much more
3G is starting to shine, even before it has reached a broad use in the United States Canada, is its use in mobile content downloading. Mobile phones are extremely popular, with several services offered by allowing users to customize their phones with unique ringtones, especially because many phones are capable of MP3 ringtones these days. Instead of a standard ring, imagine, to hear their phone off the explosion of Lil Jon's recent success, or a classic Frank Sinatra song.
Music Phone, such as Sony Ericsson's Walkman line, is also increasing in prevalence. Indeed, some said that in the year 2010, the excess air services in the mobile music - i.e. download music directly on your mobile phone on a clean air, instead of using your personal computer as an intermediary - there are more users online music shops (read: iTunes). 3G technology (and subsequent generations) have had and will continue much to do with this trend. and
3G standards :
There are three major 3G standards, which have already been deployed in selected regions around the world.
* W-CDMA: Not to be confused with CDMA the standard (which is the direct competitor to GSM), W-CDMA is "broadband" Code Division Multiple Access, and is allied with the 2G GSM. There are two ways:
UMTS or Universal Mobile Telecommunications System resources, and is sometimes referred to as 3GSM. UMTS is said to be able to download data at speeds up to 1920 kbit / sec.
FOMA defending freedom Mobile Multimedia Access, and is the mark for 3G services offered by NTT DoCoMo in
Canadian Mobility and Verizon Wireless, the latest is the marketing of its EV-DO services as "V CAST". EV-DO data transfer rate is in line with W-CDMA, which provides approximately 2Mbit/sec downlink.
* TD-SCDMA, stands for Time Division-Synchronous Code Division Multiple Access, TD-SCDMA is designed to give the Chinese people with high speed data that were not "dependent on Western technology". TD-SCDMA tests are currently underway with full deployment expected by the end of the year.
