WIRELESS NETWORK PROTOCOL FOR CONVERGING BROADCASTING, COMMUNICATION AND CONTROLLING IN A SHORT RANGED PICO-CELL

摘要

In wireless devices for transmitting/receiving at least one of broadcasting, communication and controlling, a wireless network protocol transmits repeatedly data structure with a certain period in a unit of the same cycle, and maintains synchronization of the devices in a unit of the same cycle. As a result, a frequency hopping is performed in a unit of a cycle. Here, length of the cycle is set to below 20msec so that a buffer used for transmitting/receiving a broadcasting signal and a voice/data communication has length of below 20msec. Cycles form a network cycle. Control frames included in the cycles in the network cycle are differently assigned in accordance with their use, and so the control frames may be used for various controls. A payload frame in the cycle used by a user may be set freely in the range of length of the cycle. In addition, the user may set optionally transmission direction, transmission velocity, transmission output power, etc in a unit of a frame and use the buffer in a unit of the frame. As a result, a user interface may be set simply.
