We’ve posted a few times recently about the upcoming enhancements to EV-DO, affectionately called “Revision A”. (Could someone please come up with some better names here?) Today, Sprint announced that they plan to start rolling out EV-DO Rev. A across their network in the first quarter of 2007, and will be demo’ing the new EV-DO cards at the CTIA Wireless Show in Las Vegas, along with partners Nortel, Novatel Wireless and Sierra Wireless. Besides increased speeds (the download data rate increases from 2.0 to 3.1 Mbps and upload speed goes from 144 kbps to 1.8 Mbps), Sprint is also eager to deploy Rev. A for it’s VoIP QoS features, which according to Fierce Wireless Sprint wants so it can aggressively migrate iDEN push-to-talk users onto the CDMA network while also offering them more data-rich services.
