reason for slow speed

One FAQ from USB Modem users is., Why USB Internet is slow sometimes or often?
When you go for USB-Modem, you need to ask your service provider..
whether your city has wireless broadband tower installed?
If its been installed, ensure that you have it installed near by your residence.
People will have the tendency to think that why the modem is not performing with the speed that has been promised at the time of purchase.
Its quite simple, the USB Internet is an emerging technology in India. The major service providers have their wireless broadband towers installed in metro cities.In metrocities it delivers onthe promised speed of 3.1 mbps. The broadband technology has EVDO,EDGE connections to make the data flow through the RF signals.
The other cities have only CDMA,GPRS towers installed and using this we can get only dial-up speed upto 153.6 kbps.
Its wise option for travellers who do most of their business online.
Perhaps, it'll take a couple of months for this thing to be installed all-over India.
