Often we come across posts HSDPA, 3G, WCDMA and EVDO in 'smart friend' that we have, but do we understand what the purpose of it all? lest all do not know all the terminology around us. yayayaya. but anyway no problems, Because now i will share to you all. right, starting from HSDPA. What is HSDPA?

HSDPA stands for High Speed ​​Downlink Package Access in Indonesian language gini Renk klo HSDPA modem the ability to download files that exist on the internet to a user's computer / laptop the user. Example: download MP3s from the internet. There is no mention HSDPA is a mobile telephony protocol and is sometimes referred to as 3.5 G technology HSDPA is an evolution of the W-CDMA standard and designed to enhance the data transfer rate 5x higher. HSDPA channel memdefinisikan a new W-CDMA, the high-speed downlink shared channel (HS-DSCH) whose mode of operation is different from W-CDMA channels that exist now. (Wikipedia)

There's such thing as HSUPA stands for High Speed ​​Upload Package Access gini in the Indonesian language, the ability klo HSUPA upload data from your computer / laptop to the internet user. Example: speed UPLOAD photos to our facebook.

Okay, have started to understand the technology of HSDPA and HSUPA networks? right, now go to 3G technology. often we hear of this technology, we learn about what it Yook 3G.

3G (from English: third-generation technology) is a standard defined by the International Telecommunication Union (ITU) adopted from IMT-2000 to be applied to the mobile phone network. This term is generally used to describe the development of technology teleponnirkabel third version. Through 3G, mobile phone users can have quick access to the internet with a bandwidth of up to 384 kilobits per second when the device is at rest or moving as fast as pedestrians. Rapid access is a mainstay of the 3G which is certainly capable of providing various facilities to the users like to watch videos directly from the Internet or talk to other people using video. 3G beats all its predecessors, both GSM and GPRS. Some companies will make the mobile world as the new standard 3G wireless networks on the market or developing countries.

As for the notion WCDMA is the technology used in GSM (hello, sympathy, sun, Xplor, etc.) while the technology to support high speed on the CDMA CDMA (Fren, Esia, Flexi, StarOne) called EV-DO.

W-CDMA is the name of the GSM technology that allows for 3G technology. HSDPA purposes, no other, is to increase the maximum speed of data transfer, quality of care, and efficiency.

EVDO or Evolution Data Only / Evolution Data Optimized is a standard for transmitting data wirelessly third generation communication, known as 3G, unlike 3G on GSM, EVDO specially created just for CDMA by using radio frequency. (Wikipedia)

Using CDMA 2000 EVDO network to provide access to the telecommunications network interface moving at a speed of 2.4 Mbps EVDO Rev.0, and 3.1 Mbps for EVDO Rev.A, EVDO Rev.B while still not known what speed the can be generated by this revision, which must surely superior transmission bandwidth capacity than the two previous EVDO.
