Uir Practical 7

So fast Lab7.

In Lab7 i did research on the upcoming technologies for mobile devices which are HSOPA and UMB. I get to know that there are two types of 3G technologies in the market.
HSOPA is a technology developed by 3GPP and UMB is a technology developed by CDG. The current techology for 3GPP is HSUPA and CDG is CDMA2000
Currently in the world, most of the telecommunication companies are using HSUPA technology only a small percent are using CDMA2000. But as we compare the specs between the 2 new technologies. UMB has better uplink and downlink than HSOPA. But due the high coverage of HSUPA/HSOPA base station, companies are thinking if they will try the UMB technology because they will need to build the UMB base station around the world which will cost a huge amount of money.

Thats all for Lab7 and off to Lab8 and class test 2!
