HSPA is a mobile technology which enhance data rate on wireless networks. WCDMA is a standard used in GSM technologies. Technologists upgraded WCDMA by introducing HSPA which consists of two protocols. One is HSDPA and other is HSUPA. In fact HSPA is a little upgradation of software .HSPA is related to 3G mobile networks and it provide us 14Mbps downloading and 5.8Mbps uploading speed.
With the presence of HSPA we are able to use wireless broadband as we are using wired DSL. HSDPA is specified in release 5 of 3GPP and HSUPA specified in release 6 of 3GPP.Cell phone manufacturing companies are introducing new mobiles in market for 3G network .Only 3G enable or HSPA enable mobile can communicate with BTS tower of 3G mobile networks .
HSPA is adopting very fast in all around the world. In 85 countries there are 210 HSPA operators. Most probably 47 operators are allowing 3.6Mbps HSDPA speed. There are approximately 350 HSPA enabled devices like 132 handsets, 61 notebooks, 38 data cards, 27 wireless routers, 25 USB modems, 26 embedded modules etc.

Why we need to use 3G mobile networks
IMT-2000 is a standard for 3G mobile networks and is defined by ITU(International Telecommunication Union).This standard includes technologies like GSM EDGE,UMTS, DECT,CDMA2000 and WIMAX.3G able to providing up to 14.4Mbps downloading and 5.76Mbps uploading speed. We can say 3G is a wireless broadband.3G has some drawbacks like 3G is not backward compatible to GSM. So 3G mobiles are not able to communicate with GSM towers until upgraded for 3G network requirement. 3G is available worldwide. I have presented here a statistical picture which I have taken from GSA website. This picture shows growth of 3G worldwide.
By using just 2G mobile technologies we are not able to send or receive data at a very high speed. Many mobile users using WAP to access internet but we are not able to watch TV or receive video calls. Upgrading to 3G is really very expensive for Telecom companies but in future customer will demand high data rates for browsing internet and watching TV live.
