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.

Future of Wimax in doubts

WIMAX as is a very good solution for broadband wireless internet and it is competing with cable and wired dsl(Digital Subscriber line).It’s a latest technology approved by IEEE 802.16 group.WIMAX provides point to multipoint wireless networking.
WIMAX is popular but mostly in developing countries and it will prevail in developing countries. In case of developed countries like Europe and US there is a clear signs of tough time for WIMAX. In developed countries investors are interested to invest in LTE 4G.
In future there will be security risks for WIMAX as faced by WI-FI. In start when WIMAX entered into our life very less hackers well aware about it’s security weaknesses but with the passage of time there will be more security threats to WIMAX.
Intel have invested dollar $43 million in Tokyo based UQ communication. UQ is also using WIMAX technology and they are claiming that they will reach 90% of Japan’s population by 2012.WIMAX range is upto 30 miles as compared to WI-FI range of just few hundred feet.
