Europe UK : TDC announced the availability of two new compact High Speed Downlink Packet Access (HSDPA) modules, offering faster transmission of data with speeds up to 3.6M/bits per second. They provide high bandwidth data communication services such as broadband internet, email access, and video and music streaming on portable devices.

The Siemens HC15 and HC25 from TDC allow data to be transmitted and received at up to three times the speed of ISDN. Both modules support voice, fax, SMS and Circuit Switched Data (CSD) enabling them to be used as a modem for PDAs, laptops and other devices via infrared ports or data cables.

The HC15 is a single band 3G device supporting 2100MHz and dual band operation on 900/1800MHz for EDGE/GPRS and GSM. The HC25 is configured for worldwide use and offers 3G on 850/1900/2100MHz and EDGE/GPRS/GSM on 850/900/1800/1900MHz. The HC25 also incorporates a GPS receiver to fulfil the USdirective E911.

The HC15 and HC25 modules measure just 34 x 50 x 4.5mm and weigh less than 10g, making them easy to integrate into compact designs. The modules interface to the host applications via a USB 2.0 slave interface. USB drivers for Windows XP are included as well as Microsoft RIL/NDIS drivers for Windows Mobile 5 and its successor. Normal operation temperature is between -20 to + 65 degrees C. Intelligent power-saving modes are included to minimise current consumption.

ABOVE is an economical and versatile development board for Siemens Wireless modules. The board supports the following modules:

TC63 Quad band, TC65 Quad Band GSM with Java, MC75 Quad Band with EDGE, AC75 automotive EDGE module, XT65 Quad Band with Java and GPS, XT75 Quad Band with EDGE, Java and GPS, HC15 HSDPA (3GSM) and HC25 HSDPA (3GSM). (Only one can be fitted at a time!).

The board is ideal for those wishing to develop with the Java modules as both serial ports are supported, as is the USB port, ideal for use with Eclipse and the SDK.
