摘要： A radio LAN master station system which provides long distance communication and suffers from small interference by another system located inside and/or outside of a service area comprises a transceiver, and a plurality of directional antennas each directed to a respective section with some angular spacing, through a power distributor which couples said transceiver with said antennas. Polarization plane of any antenna is orthogonal to polarization plane of an adjacent antenna.

摘要： In each of communication stations, among all of spread spectrum signal waves having the carrier frequencies separated from each other in units of an integer multiple of the frequency amount R, all the spread spectrum signal waves having the carrier frequencies separated from each other in units of an even-number multiple of the frequency amount R are converged into a first group; all the spread spectrum signal waves that are adjacent to the aforementioned spread spectrum signal waves and that have the carrier frequencies separated in units of an even-number multiple of the frequency amount R are converged into a second group; and the first and the second groups of spread spectrum signal waves are simultaneously transmitted according to orthogonal polarized waves to perform information transmission.
