The Internet speed offered by the original CDMA technology is very low as 14.4 kbps. This is the maximum Internet speed offered by single channel CDMA standard. In extended form ,that is eight channel form it offers up to 115 kbps. But for Internet usage we are using some variations of CDMA standard like CDMA2000.
Internet speed of CDMA2000 is much faster compared to traditional CDMA technology.Here theoretically we can have maximum 2 Mbps. So the speed of CDMA2000 can match the browsing requirements of todays average Internet users. CDMA2000 includes two sets of standards. They are:
1. CDMA2000 1X
2. CDMA2000 EVDO.
The expansion od EVdo is Evolution-Data Optimized.
So in a nutshell the Internet speed by different CDMA standards:
Internet speed by CDMA standard: 14.4 kbps to 115 kbps
Internet speed by CDMA2000 standard: 144 kbps to 2 mbps

Keep posting stuff like this i really like it
Thank you for your comment.
Thank you Mr.Siju for the comments.But can you clearly state between CDMA20001X and HSIA.I bought a BSNL micromax CDMA2000 HSIA MODEM.In the settings there is a question in the network mode whether i want HSIA or CDMA20001x or auto.Which is faster?Which should i choose???
George Joseph
HSIA is faster. If your location has HSIA network available (BSNL),you should select HSIA option. PS only in selected cities HSIA service is availble.
what is the difference between HSIA and EVDO; do they both point to same thing?
Hi, i have a mmx cdma2000 hsia modem. my speed is always less than 100 kbps. can i use any other than bsnl sim and get better speeds with same modem.
what are the settings for using cdma2000 hsia modem using tata photon sim??? i m not able to get it!! please help me guys in running it!!!
Hi Roy,
You can follow the steps provided in the link below. Please note that these steps are for Linux but the settings are same.

again: what is the difference between HSIA and EVDO; do they both point to same thing?
Both HSIA and Ev-Do are falls in CDMA high speed connections. Both terms are used occasionally to represent high speed CDMA connections.
For example Photon plus mention it as HSIA but other ISP like BSNL terms it EVDO.
CDMA2000 1xEV-DO (Evolution-Data Optimized) ----EV-DO
High Speed Internet Access --HSIA (Also falls in CDMA)
