Picochip has shown off its vision for next-generation femtocells, including picoXcell technology that will allow its customers to create an entire 3G cellular basestation in an ultra-small form factor such as a USB dongle. The concept of a basestation on a USB dongle is one of several Picochip developments. Others include enabling technology for small form factor public access HSPA+ femtocells; picoArray technology that is already delivering 4G services around the world and enabling LTE trials; and the company's new platform for dual mode (LTE and HSPA+) small cells. The availability of ultra-small femtocells will allow operators to easily add HSPA+ home-basestation capabilities to appliances such as residential gateways, cable modems and set-top boxes, simply by plugging in a USB key. The company said that a"private cellsite" solution like this will solve consumer problems of 'not-spots' or coverage holes,deliver far faster data services than on a conventional cell, improve battery life and enable a variety of innovative "home zone" services.
