WebWCDMA is based on 5-MHz channels using direct-sequence spread spectrum with a chip rate of 4.096 Mcps operating with paired uplink/downlink channels in an FDD mode. (Recently, the chip rate has been reduced to 3.84 Mcps, but the system characteristics remain the same.) WebChip rate is measured in "megachips per second" (Mcps), which is millions of chips per second. See spread spectrum, CDMA and 802.11. Advertisement. PCMag Stories You’ll …
