SEATTLE-Motorola Inc.’s Cellular Infrastructure Group has introduced a new radio telephone system called INReach that keeps people connected in large industrial facilities, airports or convention centers, using cellular telephones rather than proprietary handsets.
INReach interconnects with the building’s private branch exchange system, so typical cellular user fees don’t apply. “This technology allows customers to extend the mobility and tetherless capability of cellular communications to in-building (use),” said Marty Singer, vice president of business development and planning for Motorola’s Cellular Infrastructure Group.
Guests at large hotels or resorts can keep in touch with the front desk. Highly mobile employees can carry INReach phones as an extension of their desk phone.
The INReach system operates through two components along with the distributed antenna system-the INReach System Console and the Micro Cite. The console is a digital loop concentrator and an industrial personal computer. The Cite is Motorola’s first compact, fully self-contained cell site. Both units may be located with the PBX or be connected remotely. The system is scheduled to be available in the first quarter of 1995.
All call progress tones, announcements and billing can be done through the PBX, so no backhaul to a cellular switch is required. Typical system configurations can support 2,000 subscribers.
