Abstract: The present invention discloses a wireless LAN, a peer-to-peer wireless LAN, a wireless transceiver and a method of transmitting data, all of which are capable of operating at frequencies in excess of 10 GHz and in multipath transmission environments. This is achieved by a combination of techniques which enable adequate performance in the presence of multipath transmission paths where the reciprocal of the information bit rate of the transmission is short relative to the time delay differences between significant ones of the multipath transmission paths. In the LANs the mobile transceivers are each connected to, and powered by, a corresponding portable electronic device with computational ability.

Abstract: A frequency comb multiple access (FCMA) communications system in which address and message data are transmitted on a common channel to different users. The data transmitted are in the form of signatures, each of which consists of combined specific frequencies selected from a range of discrete frequencies available in the bandwidth of the common channel. Each signature corresponds to an address and to a data message directed to the address. This system does not require handshaking nor channel assignment. A transmitter and a receiver for the system are also disclosed.
