Abstract
A home networking transmitter (100), receiver (200), station (300), network manager (404), network (400) and method adapted to network devices (344/336/338/346) over phone lines (406) in a home. A bandwidth other than the 4 to 10 MHz band defined in the HomePNA 2.0× specification and a Baud rate higher than 4M baud may be used for communications between a plurality of devices (334/336/338/346). PHY and MAC layers are improved to increase the performance of home phone line networks. Advantages in the PHY layer include numerous higher symbol rates, higher constellations, variable power level, error correcting codes, byte interleaving, ISI-free pulse shape and pre-equalization. Advantages in the MAC layer include managed bandwidth resources allocation, guaranteed quality of service for latency sensitive applications, solicited grants, support to devices with low power consumption and support to device with low processing power.
