Know 3G, HSDPA, EVDO and 4G Technology

Mobile Community increasingly spoiled for choice with many connections in Indonesia. Sweet promises of the form
speed of 1.5 Mbps up to 7Mbps vigorous dipromokan by Axiata telecom operators such as XL, Indosat, Telkomsel, Axis, 3, until Esia, Fren and Smart. Overall service promises the fastest and cheapest. However, have you know the technology behind the Internet packets such Phones?
Mobile phone companies are now starting to develop new technologies that will help make telecommunications much easier and more attractive for many consumers. One is the advancement of cellular technology 3G technology. 3G technology, which stands for third generation (3rd Generation) aims to improve the EFI siensi data can be transferred via a cell phone. Speed data transfer to third generation mobile telecommunications up to 2 Mbps. In addition to this tour fi, 3G mobile phones also have a voice con-
conventional, fax and data services, as well as high resolution video and multimedia services that can be used while on the move. This also includes mobile services such as banking offi ce and online virtual, video conferencing, online entertainment and Internet access to the world. Mobile phone technology will improve the way people communicate with each other, and develop use of new things on Pop. One of the advantages of technologies such as mobile phone users the ability to use your phone to watch TV shows, and also allows for video conversations with other people who also use the same 3G technology. This makes it one of the 3G phone's most important fi tour better, this is the ability for people to do video conferencing. However, this only
forming a very small portion for the use of 3G phones. Other applications of the 3G technology include map and positioning services, multiplayer gaming, and more popular with this type of mobile phone subscribers who are younger. 3G technology on mobile phones can also benefit you with a variety of applications. 3G can help simplify the tasks of everyday such as shopping, where you can order items that you need to replenish supplies in your home, your local market will be ready to retrieve the goods once you're there, give you the opportunity in time management you.
You can also pay bills and check balances, by going to your bank account with only her
use 3G devices that you own. You can also open the book and the dinner menu booking hotels in all cities. Technology like this gives you the advantage by providing sufficient fl eksibilitas to function at your workplace. Teleconferencing is one of the best applications for 3G technology in your work.
Although the 3G technology offers many new changes and progress in the telecommunications world, still
There are some things that led to the use of 3G telephone communication systems as the technology is harmful. One thing that makes 3G cellular phones disadvantageous to its users is the fact that the type of mobile phone is more expensive than those who do not share the same technology. In addition, fi tour 3G video conferencing technology can be used only with fellow users.


History 3G, HSDPA and EVDO Network
3G was first introduced by NTT DoCoMo in Japan in branding with the name FOMA. Start-known
it in May 2001 and revised again in October 2001. Although there are constraints due to delays in data transmission network realibitas limited. Introducing a second network is SK Telecom of South Korea in 1xEV-DO network in January 2002. Nokia 6650 handset is the first to adopt the UMTS technology. In December 2007, 190 operators in 40 countries have adopted 3G tenology well, as well as 154 Telecommunications Operators in 71 Countries. In the same year, 200 million 3G subscribers already connected. Although the 3 Billion phone subscribers worldwide, only 6.7% of his course. 3G is a wireless communications standard and that the definitive portable nisikan by the ITU (International Telecommunication Union) where this technology in the network including GSM, EDGE, UMTS, and CDMA 2000, DECT and WiMax. Services included in the broad area dare voice, video calls, wireless data, and the environment. Unlike the 2G and 2.5 G which allows the use of 3G data and voice simultaneously with a maximum speed of up to 14Mbit/detik for downstream and 5.8 Mbit / sec for upstreamnya. With this 3G network, operators can more fl eksibel provide network services with more flexibility to maximize Effi ciency in the network.


Evolution from 2G to 4G
2G network is still available as a service to voice and low speed data transmission. From 2G to 2.5 G
A leap in the evolution of 2G is the first technology to introduce GPRS (General Packet Radio Service).
Then combined with voice services and switch its name to 2.5 G. GPRS can provide access speeds up to a maximum 114Kbit/detik 56Kbit/detik. It can access the technology and service WAP (Wireless Application Protocol), MMS (Multimedia Messaging Service) and email communications as well as the WWW (World Wide Web).

From 2.5 G to 2.75G (EDGE)
EDGE (Enhanced Data Rates for GSM Evolution) was introduced in 2003 by AT & T on standardized 3GPP and Amerika.EDGE is one part of the GSM family.

4G evolution
3GPP and 3GPP2 are the extension of 3G technology standards. This is because already has an IP-Network
infrastructure, and with the kembangkannya MIMO network, which is a separate character for IMT-Advanced (4G). 4G standards are capable of reaching speeds diyakinin 1Gbit/detik for downstream and for upstream 100Mbit/detik) This standard has not been achieved. Existing networks and the development of 3G is called 3.9 G or Pre-4G. Qualcomm is the courage to develop this technology. In the month of December 2009, Telia Sonera announced to the world's first 4G technologies to customers. Countries that are able to taste this technology in Stockholm, Sweden, Oslo, and Norway.
