| 摘要 |
The present invention is a wireless terminal device comprising a plurality of antennas (50), wherein the plurality of antennas (50) are used in sequence to communicate with adjacent terminals which are other wireless terminal devices, and a mesh network is formed in which relay channels from the adjacent terminals to a gateway are automatically altered according to changes in the wireless communication environment. The wireless terminal device comprises an information acquisition unit (communication controller (57), communication quality measuring unit (61)) for acquiring from the adjacent terminals information on the number of hops from the adjacent terminals to the gateway and measuring communication quality with the adjacent terminals in each of the antennas (50) when the antennas are used, an antenna switch (51) for switching the antenna being used, and a used antenna determination unit (communication controller (57)) for determining the antenna being used during reception on the basis of the hop number information and the communication quality and causing the antenna switch (51) to select the determined antenna. |
