What is CDMA 1x ?

CDMA 1x is the previous version or the older version of EVDO which has speed upto 144kbps.

If BTS near you is not Evdo enabled then you will get CDMA 1x speeds of upto144kbps.

Speeds & Performance depend on Signal Strength which varies place to place . some people have reported to get about 1.5mbps speed and some only get around 100kbps only. so i would suggest you to contact your nearest local exchange and ask for a live demo. here is a brief account of my personnel experience.

In Bsnl EvDO you aren’t directly connected to Internet.instead you are connected to a Proxy server on bsnl’s network which has a private IP, in 10.xx.xx.xx range. that proxy server then connects to Internet Gateway aka National Internet Backbone. so as a result, proxy server blocks all incoming connections to it, except those coming from known ports like port 80,443 etc.Every Proxy server has a unique Public IP address, and all subscribers connected to it will share that Public IP address. Its entirely different from convention when every Subscriber has unique Public Ip address This Approach was two shortcomings:




Bsnl Evdo is good service with gives excellent speeds on the move comparing to other alternatives like GPRS. The technology involved is quite new in India, this can be judged from the fact the DOT has not issued any format licenses for 3G CDMA. when licenses are issues we would expect similar roll outs from other operators also. I would recommend people to try this service atleast once, if they find it suitable they should subscribe to it Further Reading:
