  1. does data card speed effect CDMA network PERFORMANCE ? —– being a old version micromax mmx 310c data card is having speed of 7.2 Mbps while latest MMX 350C CDMA data card provides up to 3.1 Mbps speed ……..but this latest one is compatible for windows 8 and above but MMX 310C will not work with upgraded windows OS ……now i m running windows 7 ….which one I need to buy …

      • Kamlesh Sir ——what is Rev B EvDO technology ….a friend of mine saying “select dongle that is compatible to RevB technology because Relaince is upgrading their network to RevB” ——-does MMX 350C CDMA DATA CARD compatible to Rev B ?

        • Micromax has listed in the company website as EVDO at http://www.micromaxinfo.com/dongles/3g-data-card/mmx350c

          He does not mention Rev. A or Rev. B. So, you can expect Rev. A.

          EV-DO Rev. B is a multi-carrier evolution of the Rev. A specification. It maintains the capabilities of EV-DO Rev. A, and provides the following enhancements:

          Higher rates per carrier (up to 4.9 Mbit/s on the downlink per carrier). Typical deployments are expected to include 2 or 3 carriers for a peak rate of 14.7 Mbit/s. Higher rates by bundling multiple channels together enhance the user experience and enable new services such as high definition video streaming.

          Reduced latency by using statistical multiplexing across channels—enhances the experience for latency sensitive services such as gaming, video telephony, remote console sessions and web browsing.

          Increased talk-time and standby time

          Reduced interference from the adjacent sectors especially to users at the edge of the cell signal which improves the rates that can be offered by using Hybrid frequency re-use.

          Efficient support for services that have asymmetric download and upload requirements (i.e. different data rates required in each direction) such as file transfers, web browsing, and broadband multimedia content delivery.
