Systems and methods for powering network access devices from customer premises equipment
A communication system has a network access device (NAD) that is designed to deliver Plain Old Telephone Service (POTS) along with high-speed data to Customer Premises Equipment (CPE).

Certificate echoing for session security
A client establishes a cryptographically protected communications session with a server. To detect a man-in-the-middle, the client echoes information about a certificate purportedly received from the server.

Adaptive synchronous protocol for minimizing latency in TDD systems
Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases. |
