Motorola Inc has a Mobile Business Unit which is currently investigating the integration of mobile communications systems into portable computers, according to Wireless Internet and Mobile Computing, a Chevy Chase, Maryland-based publication. The unit is working on PowerPC-based notebook computers with wireless technologies built in, supporting voice, data and video, and is talking both to internal Motorola units and independent companies about the technology that could be included. Motorola’s options include the use of various chipsets and radio modules into notebook computers for two-way paging, packet radio, PCS and cellular communications, said the publication.
