System Description

The Point-to-Multipoint (PMP) system is an advanced digital broadband fixed wireless access system and is a cost-effective solution for voice, data, video, and Internet communications. PMP is capable of supporting Asynchronous Transfer Mode (ATM) and Time Division Multiplexing (TDM) based services. PMP uses Frequency Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA) technology combined with highly efficient 64-QAM modulation techniques to provide wireless access for multi-tenant buildings, small and medium size businesses, and PCS and cellular backhaul services.

The PMP system delivers end-user service from hub stations in cells that can extend up to 10 kilometers, depending on frequency, traffic, and availability demands. To provide up to 360° of coverage, each hub can have up to 24 sector subsystems, each with sector antennas and associated communications equipment.

The new high-capacity remote IDU contains all the necessary baseband electronics. Implementation is flexible and unsurpassed in reliability. The PMP system interfaces with existing PBXs, computers, LANs, routers, switches and bridges. In addition, highly efficient modulation schemes and dynamic power control enable extensive frequency reuse assuring maximum capacity and the highest degree of service.
