EVDO Rev 0 vs EVDO Rev A
We get this question every day, so, here is some information regarding EVDO Rev A vs. EVDO Rev 0.
EVDO Rev A is 25% faster at downloading and up to 800% faster at uploading (and has lower latency).
Both Sprint and Verizon are currently upgrading their EVDO Rev 0 towers to support EVDO Rev A.
Older Rev 0 cards are compatible with Rev A towers, BUT at Rev 0 speeds.
You need both a Rev A card and Rev A network for faster speeds (and lower latency).
Since you have to sign up for a 1 (or most likely 2 year contract), DON'T get an EVDO Rev 0 card. You will find it very costly to upgrade to a Rev A card once you are already in a contract ($250 - $330).
The current Rev A cards are:
Sprint Order Form
Merlin EX720 ExpressCard
Novatel S720 PCMCIA
Ovation U720 USB
Pantech PX-500 PCMCIA
Sierra AirCard 595
Verizon Order Form
Novatel V740 ExpressCard
Novatel USB720 USB
Audiovox PC5750 PCMCIA
Sierra AirCard 595 PCMCIA
