What is a "Cdma Frequency Range"? The Most Authoritative Explanation.

What is the band used in CDMA?

Centralized Methods 1 The band used in CDMA is 824 MHz to 894 MHz (50 MHz + 20 MHz separation). 2 Frequency channel is divided into code channels. 3 1.25 MHz of FDMA channel is divided into 64 code channels.

What are the features of CDMA?

CDMA, which is based on the spread spectrum technique has following salient features − In CDMA, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence and then transmitted using a wide frequency range.

Why is frequency arrangement not possible in a CDMA system?

In actual situation, because of complicated radio propagation and irregular cell allocation, it is not easy to allocate frequency (or timeslot) appropriately. In a CDMA system against this, since all users share the same frequency, the arrangement of the frequency is not an issue.

What is the capacity advantage of CDMA?

The major capacity advantage of CDMA is that it reuses the same allocated frequency in every sector of every cell. In IS-136 and analog cellular systems, there is a seven cell repeat factor, with three sectors. This means that only one out of every 21 channels is available to each sector.
