Description of the Related Art At present, radio equipment (radio station license) and radio equipment that does not require a qualification include specific low-power radio equipment and weak radio equipment. These radio equipments are obliged to limit radio wave output (up to 10 mW) and to automatically transmit identification signals.

High bps and 3GHz or less (quasi-microwave band)
Therefore, a semiconductor device to be mounted can be manufactured at a low cost, and a computer wireless LAN such as an office can be manufactured.
(Local area network). As for the spread spectrum (SS) method, for example, JP-A-8-195699 and JP-A-7-170210 are referred to.

る。Conventionally, when a wireless LAN is used, it is assumed that the wireless LAN is used in an open space without walls, such as an office, eliminating the need for a LAN cable in the office, facilitating computer mobility, In addition, it contributes to improving the appearance without wiring. For communication to another office, the user uses a LAN cable on the wall.

The distance between stations is less than 10 m when cut off by a concrete wall. Radio waves do not reach between an office and a computer at the end of another office, and communication becomes impossible.

う、ということである。(1) The first problem is that the biggest advantage of wireless communication is that when performing communication between rooms where wiring is difficult, wireless communication is performed in a closed space with walls or the like. In wireless communication with radio wave output restrictions, such as specified low-power wireless equipment, the communicable distance is greatly reduced.
【００１１】その理由は、無線通信の電波群が壁等にぶ
