Tim Higgins notes that it might not be smart to connect for cell data to your smartphone via Bluetooth: Bluetooth 1.2, the version most likely found in any given smartphone, tops out at a little above 700 Kbps, well below the top download burst rates available with EVDO and HSDPA. Higgins found in testing that connecting a smartphone via USB provided substantially improved throughput—in one case a best rate three times higher than with Bluetooth.
Bluetooth 2.0+EDR closes in on 3 Mbps, but as a newer flavor, it’s less available due to chip expense. It’ll eventually become the standard, even as EVDO Rev. A moves to over 3 Mbps of burst download speed and HSDPA hits similar marks. (Power usage, may be less of a constraint, because 2.0+EDR “talks” less to achieve the same throughput, thus being more efficient per bit.) [via JiWire]
The mobile access equipment maker Novatel rolls out new family of adapters: The company’s HSDPA/HSUPA products include a new ExpressCard (Merlin X950D), HSDPA USB Modem (Ovation MC870D), an embedded module (EU870D/EU860D), and an ExpressCard to USB adapter (Merlin XUA-1). The ExpressCard is a worldwide HSDPA, HSUPA, EDGE/GPRS modem with support for full 7.2 Mbps HSDPA speeds, and a future firmware upgrade for 2.1 Mbps HSUPA. HSUPA hasn’t been rolled out yet in any significant way because the focus is always on the downlink side for cellular operators. The Merlin XUA-1 is a unique adapter, allowing the use of an ExpressCard via a USB 2.0 port.
Sprint brings EVDO Rev A to Mac and Windows laptops through Novatel Wireless ExpressCard modem: The EX720 will run $180 with a two-year commitment. The announcement explicitly states support for Mac OS X and Windows. Sprint’s monthly service is $60 per month for unmetered usage with a two-year commitment, but no voice plan is required. The ExpressCard is found in most new laptops sold to professionals, and Apple’s single MacBook Pro high-end laptop model. (I write unmetered because it’s not unlimited: there are limits to use.) Sprint already offers a Novatel USB modem, and three PC Card modems.
The EVDO Rev. A network operates at substantially higher upload speeds than Rev. 0 and somewhat better download speeds—average speeds tend to be reported as 200 to 350 Kbps up and 450 to 800 Kbps down. Sprint is claiming in a release 350 to 500 Kbps up and 600 Kbps to 1.4 Mbps down!
The card, like all EVDO Rev. A modems, works with Rev. A and Rev. 0 networks, as well as 1xRTT, a modem-speed standard.
