What is The Normal Internet Speed Using CDMA Technology

CDMA (Code Division Multiple Access) is one of the popular mobile transmission technologies in voice and data communication. Many service providers offer CDMA based dedicated mobile broadband connection. Let us check the difference in speed offered by various standards. 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. However, even this eight channel form is not enough to start a high-speed connection. So for Internet usage, we are using some variations like CDMA2000.

Upgrades of Code Division Multiple Access

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 today's average Internet users. CDMA2000 includes two sets of standards. They are:
  1. CDMA2000 1X

  2. CDMA2000 EVDO

The expansion of EVdo is Evolution-Data Optimized. Now let us compare the speed difference of different standards.

  1. Internet speed by CDMA standard: 14.4 kbps to 115 kbps

  2. Internet speed by CDMA2000 standard: 144 kbps to 2 mbps

One major disadvantage for using CDMA phones to access the mobile Internet is its higher need for energy. It is widely noted that CDMA technology forces mobile phones to use more battery charge and reduce the battery life. However, if you are using a USB modem to access the Internet on your laptop, this issue won't affect much. Tata Photon and Reliance Netconnect are providing USB modems to connect CDMA mobile data network. These Service Providers offer HSIA for high paying customers and CDMA for low paying customers. For example, Photon plus uses HSIA standard but Photon Whiz uses simple CDMA1X. Another example is Micromax CDMA2000 HSIA modem.

I hope this article is enough to calculate the normal Internet speed using CDMA technology. If you are confused with different terms like GSM, CDMA, HSIA, etc, I recommend you to visit the link below. In that article, I have clearly written the bandwidth of each mobile communication technologies.

    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???

  4. 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?

  6. Anonymous3:32 AM

    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.

  7. 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!!!

    1. 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?

    1. 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)

      Hey, I have a mmx cdma2000 hsia modem. my speed is generally under 100 kbps. could I at any point utilize some other than bsnl sim and get better rates with same modem.

    3. To answer this I need to know the model number of your CDMA modem.
