WebWCDMA is a step further in the CDMA technology. It uses a 5 MHz wide radio signal and a chip rate of 3.84 Mcps, which is about three times higher than the chip rate of CDMA2000 (1.22 Mcps). The main benefits of a wideband carrier with a higher chiprate are: • Support for higher bit rates • Higher spectrum efficiency thanks to improved WebChip rate is measured in "megachips per second" (Mcps), which is millions of chips per second.
