Explain CDMA/TDMA/FDMA?
Answer / sree
CDMA - code division multiplexiling
FDMA - frequency division multiplexing
TDMA - Time dividsion multiplexing.
the mentioned above three are the techniques used in call management practically .
..
In CDMA , at a time no.of calls can be routed to last mile with limited losses in signal strength.
In FDMA , it can be used in GSM tech for encrypt & de-crypt
In TDMA , can be utlilized
