Diversity control method
First Claim
1. A diversity control method of selecting a plurality of antennas having directivities and disposed in different directions, comprising the steps of:
- selecting at least two antennas from the plurality of antennas;
performing first diversity control of comparing strengths of reception powers of the selected at least two antennas and selecting one antenna having a stronger reception power than others; and
performing second diversity control of comparing radio conditions of the at least two antennas in a predetermined period if the radio conditions of the at least two antennas have deteriorated in the first diversity control and changing at least one of the antennas to another new antenna based on a compared result.

Abstract
A diversity control method of selecting a plurality of antennas having directivities and disposed in different directions is disclosed. At least two antennas are selected from the plurality of antennas. First diversity control of comparing strengths of reception powers of the selected at least two antennas is performed. One antenna having a stronger reception power than others is selected. If the radio conditions of at least two antennas have deteriorated in the first diversity control, second diversity control of comparing radio conditions of at least two antennas is performed in a predetermined period and at least one of the antennas is changed to another new antenna based on a compared result.
