Sony Ericsson used the GSM Mobile World Conference to launch two new mobile broadband ExpressCards. The EC400 and EC400g simply slide into a laptop's Expresscard slot to allow 7.2Mbps (megabits per second) in download and 2Mbps uploads.

Both cards feature an integrated antenna as well as an additional second antenna that can be flipped up to improve signal reception. The built-in software ensures your network provider is automatically identified and the appropriate network parameters are applied as soon as the card is plugged into your laptop. The EC400g is also equipped with a GPS receiver that identifies and highlights the user’s current location on Google Maps or a similar service.

"With their plug-and-play installation and configuration, the ExpressCards offer immediate access and instant download speeds, allowing you to effortlessly keep pace with the demands of your business," said Johan Tysklind, marketing director of mobile computing at Sony Ericsson.

The cards will be available worldwide by mid-2008 although prices have not been confirmed yet.
