Since the launch of the world’s first EV-DO Rev. B network in January 2010, many EV-DO operators around the world have either launched or are in the process of launching their Rev. B commercial networks. Momentum is building, and soon Rev. B will be transforming the user experience of millions of EV-DO subscribers.
Rev. B is a cost-effective upgrade from Rev. A and occurs in two phases — Phase 1: Multicarrier, and Phase 2: Hardware.
Phase 1: More channels, more speed
3x faster data rates for all users
Using multicarrier, Rev. B triples existing data rates for all users in the cell including those at the cell edge. It also doubles the capacity for bursty applications such as web browsing.
Phase 2: Greater capacity, double-digit data rates
The second phase of a Rev. B upgrade raises downlink peak rates to an amazingly fast 14.7 Mbps by employing the commercially available CSM6850 cell station modem. This highly optimized modem supports four carriers on a single card, lowering deployment cost for operators. Phase 2 also introduces BTS interference cancellation, which increases uplink capacity by ~65%.
A robust Rev. B device market is already in motion
Qualcomm’s wide range of chipsets has helped populate and accelerate the Rev. B device market with everything from USB dongles/ modems to feature phones and smartphones.
