摘要： Wireless communication systems using transmitter initiated communications methods. Several devices in the system listen by following a common frequency hopping sequence. When communication is desired, a transmitting device sends a request to send signal to an addressee; if available, the addressee sends a clear to send signal, and the transmitting device and the addressee then perform communications using a separate frequency hopping sequence. Methods for adding new devices are also included. In an example, a new device uses a discovery frequency hopping sequence to ping a number of frequencies until the common frequency hopping sequence is discovered. In another example, a new device listens on a single frequency forming part of the common frequency hopping sequence until the common frequency hopping sequence overlaps the single frequency.

摘要： Various techniques are disclosed for improved reliability of wireless communications using packet combination-based error correction. For example, a method includes receiving a first message transmitted wirelessly, where the first message contains a first copy of a data packet and has at least one error. The method also includes receiving a second message transmitted wirelessly, where the second message contains a second copy of the data packet and has at least one error. The method further includes identifying a set of bit positions based on where the first and second copies of the data packet differ and modifying the set of bit positions to produce a modified set of bit positions. In addition, the method includes modifying one or more bit values in the modified set of bit positions to produce at least one modified copy of the data packet and determining if the at least one modified copy of the data packet is error-free.
