AnyData launches first cellular 'world modem'

By Gary R, in , posted: 24-Jan-2008 17:15

The AnyData ADU-630W is the first USB modem to operate on either UMTS or CDMA networks offering a true world modem in a single package.

Inside are separate radio modules and diversity antennas to support both UMTS and CDMA. On the outside are separate external antenna connectors for UMTS and CDMA. LEDs notify which sort of network the modem is connected to. The modem supports:
  • GPRS/EGPRS - 900/1800MHz
  • HSDPA - 2100MHz (up to 7.2Mbps)
  • CDMA 1xRTT, EVDO Rel0, EVDO RevA - 800MHz
The modem comes with a removable Li-ion battery pack which offers a power boost for when a laptop is operating on battery or for USB ports which will not deliver enough power. The modem uses a single USB port and it shows up as a single USB device in Windows. The software uses a debug port to select which radio module to operate.

The obvious limitation is that the CDMA side of things requires carrier approval and data roaming agreements. The HSDPA side of things just requires a SIM card.

It is quite a small package measuring just 50x100x14mm and weighing around 30g. Not bad considering all the electronics crammed into the case. It is not a simple task to build a radio device that operates on so many different frequencies when interference and multiple antennas have to be considered.

So far the modem has been released by a carrier in Eastern Europe where it is configured for CDMA 450MHz.

Wow... This would be great for Telecom New Zealand, since they are going to have both CDMA EVDO and HSDPA networks running in parallel for at least the next five years - good solution for users who need roaming overseas.
