An antenna system is provided for use in wireless communication, the antenna system is contained in a modular structure. The antenna system includes a plurality of co-located antennas, including at least one active modal antenna, each of the antennas being adapted for operation at a distinct frequency band. The antenna system further includes an active tuning module for tuning a frequency response of the co-located antennas.

Multi-antenna module containing active elements and control circuits for wireless systems

A method and apparatus for flexibly filtering upstream scheduling messages in a communication system is described. The inventive method and apparatus uses software to rapidly filter a MAP message comprising a plurality of information elements. In accordance with the inventive method, a communication device inputs a MAP message and outputs a filtered MAP message comprising upstream transmission information relevant only to the communication device. The communication device stores data relevant to its upstream transmit opportunities. This data is derived from information elements that are associated with the communication device. In one embodiment, the communication device stores a transmit time. In another embodiment, the communication device stores a transmit time and a transmit duration. In yet another embodiment, the communication device stores a transmit time, a transmit duration and an IUC.

An interrupt driven interface coupling a programmable media access controller (MAC) and a process controller. The interrupt driven interface is operable within a cable modem system. The specification by which the cable modem operates to transfer data between the programmable media access controller (MAC) and the control processor is loaded into a memory location within the system, and the physical system is operable to provide for backward compatibility, in that, the addition of new messages and the deletion of old messages within the specification is performed via software upgrade. The necessity of a re-design and re-fabrication of the programmable media access controller (MAC) and the control processor, and the interface between them is completely obviated by the present invention.
