Title: Transmission power control method for phs base station
Inventor: WATANABE MASAHIDE
IPC: H04B7/26
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To suppress the variance of a callable area for a PHS base station regardless of weather conditions by controlling the transmission power of the PHS base station based on the parameter concerning the weather. SOLUTION: The radio wave propagation characteristic of a PHS using the carrier of 1.9GHZ band is easily affected by raindrops and snow, and the transmission loss, i.e., the ratio between the transmitted power Pt and the received power Pr is reduced in the fine weather and increased in the bad weather. In other words, the weather is bad with high humidity and low atmospheric pressure. In this respect, the humidity and the atmospheric pressure are used as the parameters concerning the weather. Both humidity and atmospheric pressure information are inputted to a transmission power controller 4. The controller 4 calculates at a every prescribed time the transmission power accordant with the weather based on a fuzzy rule and controls the transmission power according to the calculation result.  The standard atmospheric pressure is decided based on the past monthly average value calculated at the place of the PHS base station.

IPC: H03K5/13
Filed: 1990-09-28
Abstract: PURPOSE:To make an output stable by providing a capacitor in parallel with a CMOS buffer between the input and the output of the CMOS buffer. CONSTITUTION:When the input voltage from an input terminal IN changes from a logical high level to a logical low level, the input voltage of a CMOS buffer B is decreased gradually in a rate of the time constant.
