Ericsson's Screen Phone, which runs the open-source Linux operating system, combines both Internet access and a speaker phone, and will communicate with a homebasestation using the emerging Bluetooth technology for wireless personal area networking.
The H9080 are charged via the included homestation which also doubles as a homebase for the headphones preventing users from misplacing their headphones.
These modules, powered by AAA batteries, can be placed anywhere in your home and will simultaneously blast audio alerts on the basestation and the wireless speakers.
