Different of Types 3G
Just as with other types of technologies, there are also different of types 3G. You can take advantage of the many features and developments by simply knowing how one type differs from the other. You can save more money by investing only in the right product that actually offers you all the right tools and applications for personal use and work.
You also need to know a bit about the existing networks to know how much speed you are actually getting.
The Types
The two main types of 3G are UMTS or Universal Mobile Telephone Service and CDMA 2000. UMTS is spread out over the present GSM networks, while CDMA2000 takes 3G speeds to CDMA networks. The two types have a couple of high-speed misses, the voice-plus-data 1xEV-DV and the data-only 1xEV-DO, which are currently available in chosen suburban regions and major cities.
More expansion is underway in the near future. The speeds for both UMTS and CDMA2000 are estimated to be about the same as a regular DSL. AT&T has also released a 3.5G speed network in 2006. This is called HSDPA, which stands for High-Speed Downlink Packet Access.
This begins at a speed of about 1.8 Mbps up to an excellent 14.4 Mbps. More devices and networks are being developed at present, introducing the 4G technology, such as WiMax.
3G Capability
To get the benefits and features of 3G technology, individuals will need a 3G phone or smartphone. The start was kind of slow, but there is now a wide array of handsets, featuring 3G technology from different carriers. All the mobiles will try to provide support for the recent 3G networks.
These appear in different styles, ranging from trendy to stylish. Some of the best examples include the Samsung SPH-M520 and LG Venus VX8800. The best 3.5G phones are supported by HSDPA phones, such as the AT&T Tilt and the LG CU720 Shine. Prices of the products will differ, depending on the available features and the brand.
The Different Technologies
Both PC and laptop users can get benefits from 3G networks for mobile broadband, excluding a Wi-Fi network. Individuals will only need a carrier-supplied PC Card. There are PC cards available for both EV-DO and HSDPA networks. Knowing the evolution will help you choose the right product and assess how much you are actually getting.
1G technology include AMPS, the speed is still very slow compared to today’s standards with voice only analogue feature. The 2G technology includes iDen, CDMA and GSM, with speeds less than 29 Kbps. Included features are the push-to-talk, voice, conference calls, caller ID and SMS.
2.5G technology includes EDGE, GPRS and 1x RTT, featuring speeds from 30 Kbps to 90 Kbps. The included features are MMS, web browsing, images, short video and audio clips, applications, ring tone downloads and games.
Recent Technologies
3G technology includes UMTS and 1xEV-DO ranging from 144 Kbps up to 2 Mbps. Some of the included features are full-motion video, quick web browsing, 3D games and streaming music.
3.5G technology includes HSDPA which is an upgrade for UMTS and 1x EV-DV, with speeds ranging from 384 Kbps up to 14.4 Mbps. Features include video conferencing and on-demand video. 4G and more features speeds from 100 Mbps up to 1 Gbps.
Some of the outstanding features include high quality video conferencing, high quality streaming video and voice-over-IP telephony.
Introduction to 3G Technology
3G services for mobile devices have been introduced by various handset creators and cellular carriers. The companies, however, are not very good at explaining the exact details, except for a given few. There seems to be a missing link between the current standard from previous services provided by 2.5G or 2G technology.
Knowing the types and details will help you pick the right tools for your personal use or business. Here are some features.
About 3G
3G cellular technology is defined as the provision of wireless broadband data and information services right to a person’s mobile unit.
Compared to the previous technologies, 3G promises speeds ranging from 144 Kbps, which is 3 times faster compared to the traditional 56K dial-up modem connection up to 2.4 Mbps, which is very near cable-modem speed.
The networks of 3G allows you to browse quickly through web pages, watch on-demand video programs, download and play music, videos and 3D games, watch streaming videos and music videos and have a video conference with others located on the other side of the plant.
More Developments
The HSDPA is a new technology, which may also be called 3.5G, coming very soon. This offers fasters speeds of up to 7.2 Mbps and also promises the likes of 14.4 Mbps very soon. The interface is very much different on a cellular phone, but other experiences like downloading, streaming, web browsing and sending messages and email can be very comparable to a computer broadband connection.
As of the present, there are 3 big carriers that introduced and launched 3G services. There is also a wide array of 3G-enabled handsets now. In early 2005, Verizon Wireless first marketed the devices. Sprint and Cingular followed soon after. Cingular is now known as AT&T. T-Mobile is also joining the pack as it introduces its new 3G network in 2008.
The Accesses
Currently, 3G technology is the most recent in mobile communications. 3G is the shorter term for third generation, making analogue cellular technology generation one and digital/PCS generation two. The 3G technology is planned and devised for the real multimedia cellular phone, also known as smart phones. These tools feature higher bandwidths and transfer rates to cater to web-based applications and phone-based video and audio data files.
The most common include CDMA2000, which is based on code division multiple access, TD-SCDMA, which stands for Time-division Synchronous Code-division Multiple Access and WCDMA or UMTS which stands for Wideband Code Division Multiple Access.
The Networks
3G networks have the capability of transferring speeds up to 3 Mbps which is equivalent to around 15 seconds for every download of a 3-minute MP3 song. To compare, the speediest 3G cellular phones can move speeds up to 144 Kbps, which is equivalent to around 8 minutes to download a 3-minute MP3 song. The high data rates of 3G are recommended when downloading or acquiring information online, as well as sending and receiving huge multimedia files.
3G phones are comparable to small laptops that can cater to several broadband applications like browsing the internet, receiving streaming videos online, video conferencing and sending and receiving faxes.
The soaring towers are among the most important element of the group, allowing the data to be transferred from one hone to another. 3G basically is a cellular phone network protocol.
