Wireless communication device that is capable of improving data transmission efficiency

摘要

A wireless communication device includes a data transmission and reception section that wirelessly transmits a plurality of test packets; a signal sensing section that senses a power of a spatial radio wave signal on a frequency channel that is the same as the plurality of test packets and outputs sample data of the sensed spatial radio wave signal; a calculation processing section that converts the sample data into time series sample data; a collision detection section that calculates a packet collision rate based on the number of packet collisions and the number of the plurality of test packets if there is a packet collision due to interference of the plurality of test packets with another communication; and a control section that adjusts a parameter that the data transmission and reception section uses based on a calculation result of the collision detection section.

1. A wireless communication device, comprising:
a data transmission and reception section that wirelessly transmits a plurality of test packets; a signal sensing section that senses a power of a spatial radio wave signal on a frequency channel that is the same as said plurality of test packets and outputs sample data of the sensed spatial radio wave signal; a calculation processing section that converts the sample data that are output from said signal sensing section into time series sample data in which the sample data are plotted in time series; a collision detection section that determines whether or not there is a packet collision due to interference of said plurality of test packets with another communication based on said time series sample data and calculates a packet collision rate based on the number of packet collisions and the number of said plurality of test packets that have been transmitted if said packet collision occurs; and a control section that adjusts a parameter that said data transmission and reception section uses to transmit data based on a calculation result of said collision detection section.
