Wireless method for gates

摘要

The method involves executing channel hops in a time raster between (0.625 -10) millisecond adaptively selecting the channels utilized for frequency-hopping method. A complete communication cycle is provided comprising an incoming data transmission, and a response takes place on the channel within the time raster. The number of transmitted data is adapted to the useful data that must be transmitted. The establishment of a connection is synchronized between a stationary unit (12) and a mobile unit (4) on an adaptively predetermined synchronization channel.
