Aspects of the present invention relate to methods and systems for managing and allocating bandwidth in a communication medium. Some aspects relate to the determination of bit usage patterns for use in allocating bandwidth. Some aspects relate to the further determination of a derived usage pattern from the bit usage patterns and allocation of tone-slots within the derived usage pattern.

Methods and systems for frequency and time division access

The embodiments of the present invention provide a mechanism to synchronize centralized networks. Each centralized network includes a central coordinator controlling and managing network activities. The embodiments provide a way of allocating beacon slots, such that one of the beacon slots is synchronized to the alternating current line cycle and thus functions as a master timing sequence. In some embodiments, methods, devices, and systems are provided for detecting transmissions of non-coordinating networks.

Synchronizing channel sharing with neighboring networks

Embodiments of the invention provide methods, systems, and devices that coordinate access to a common medium between two networks. Typically, a gateway is employed that requests resources from a home central coordinator and/or access coordinator. If resources are not available from the home central coordinator and the access coordinator, a neighbor network protocol is performed to obtain additional resources.

Coexistence of access provider and in-home networks

Embodiments of the present invention comprise methods and systems for establishing, managing and transitioning between network coordination modes.

Method for transitioning between coordination modes for interfering neighbor networks

Aspects of the present invention relate to distributed network coordination and administration. Some aspects relate to network coordination and management using an interfering network list that may be maintained by a network controlling authority. Some aspects relate to allocation of specific bandwidth segments by a network controlling authority to avoid network collisions and improve network efficiency.
