Hi, CDMA, (Code division multiple access) is one variant of an RF Network using CDMA protocols. Many other protocols exist and many are designed just for the application.

Google CDMA and you will find many articles.

THANKS DEAR

BUT I WANT KNOW WHAT THE DEFFRANT OF C.D.M.A & R.F

Solanki Jigar,

Hi, I can add little to what I said before but perhaps this will make matters clearer.

1 RF networks are Networks engineered utilising Radio Frequency (1 to 100 MHz approximately) to convey information from one user to other , perhaps multiple users.

2 CDMA or Code division Multiple Access is a set of protocols which define how the network is addressed, how signals are sent, how addresses are worked out, how instantaneous power levels are computed, how signals are routed, how information is secured and protected and so on. I guess that CDMA could be employed over RF Networks but it is primarily a protocol for wired networks, I believe.

3 Other Network protocols include Bluetooth and WiFii albeit these are in different frequency bands. There are many, many other protocols in existence, and in daily use.

4 Different protocols would be designed and employed for different requirements and can be designed from the ground up or maybe variants of existing protocols.

I do hope that this is a sufficient explanation; if not go to Google and Wikipedia where different levels of explanation can be found.

Good Luck

Sleepy

THANKS DEAR

I M VERY HAPPY TO YOR ANS BUT ALSO YOU KNOW WHICE NETWORK IS GOOD

FOR US IN MOBILE TACNOLOG.

IF HAVE ANY KIND OF INFORMATION IN ABOVE MATTER PL. TELL ME

THANKS & REGARDS
