CDMA is actually a digital cellular technological know-how that uses spread spectrum methods to enable multiple consumers to share the identical frequency band, enabling more efficient use of your accessible spectrum.
DSSS is Direct Sequence Spread Spectrum Technique which is a spread spectrum approach wherein the data being transmitted is encoded utilizing spreading code and acquired and after that decoded using the exact code.
EV-DV is surely an extension of cdma2000 1x that provides the voice provider along with large-speed data exactly where data rates can reach higher concentrations than Those people with EVDO. EVDO has long been the popular data engineering for cdma2000 networks whereas EVDV has long been on the halt given that 2005.
The most up-to-date experiments on HSPA downlink speeds completed by Ericsson in laboratory ailments happen to be capable to succeed in up to 168 Mbps.

The spherical excursion delay amongst A and B is 80 milliseconds and also the bottleneck bandwidth on The trail involving A and B is 128 kbps. What's the choose
When a mobile is "exploring", it can be trying to find pilot indicators around the network by tuning to individual radio frequencies and doing a cross-correlation across all doable PN phases. A strong correlation peak consequence indicates the proximity of the BTS.
Packet Data Protocol: EVDO employs a packet-switched data protocol, which means data is Packet Data Services split into packets ahead of transmission. Every packet is encapsulated with specifics of its supply, destination, and sequence within the data stream.
