USB EV-DO Rev. A modem reviewed

5 Comments

Sprintnovatelovationu7206Those folks at SlashGear have gotten their hands on one of the first EV-DO Rev. A USB modems out there and have published a review of the littlest high speed modem.  It looks like the Sprint U720 USB modem is a little bigger than I would have expected but it’s great to see a USB modem for the next generation of EV-DO being released.  SlashGear got the new Sprint modem working on a Mac too which is good news for all the fanboys out there.  I have to admit I am surprised that the observed speeds of the U720 were lower than those I regularly get with my Verizon PC Card modem even though my service is not Rev. A. yet.  The U720 review reports speeds of "512Kbp/s downstream and 312Kb/s upstream" which is far below the capabilities of the Rev. A standard. The Sprint U720 opens new possibilities for UMPC owners without a PC Card slot and it’s cool to see these USB devices appear in the real world.

UPDATE:  SlashGear tested the Rev. A modem in a market where Rev. A has not been deployed so that is the reason for the low bandwidth they report.  The reported speeds are still far lower than the first generation EV-DO I get with my PC Card.  I wonder if that’s a trade-off in these super small modems with tiny antennas compared to the PC Card big brothers?

I can’t believe the size of the antenna would be the bottleneck, but I don’t live in a market with any EV-DO, so I can only look and dream while tethered to my various coffee houses.

I remember when the quality of the espresso determined my patronage.

Probably a USB power issue, not enough juice out of the 5V .5 amp USB supply to reach the highest peak RF power for the highest perormance.

When I tether my Samsung ZX20 (HSDPA) phone via USB not only does it not charge the battery but the phone will actually run down the battery.
