This will affect the operating time of the wireless terminal.

  Specifically, when the frequency of the regular communication is high (the interval is short), the operation time of the wireless terminal is shortened. Conversely, when the frequency of the regular communication is low, an appropriate connection destination cannot be appropriately selected. Arise.

  Therefore, in Patent Document 1, in a wireless terminal device, when something touches a provided key, contact detection means for detecting this and a key provided to each of a plurality of keys are provided. A press detection means for detecting whether or not the key is pressed and an invention for executing a process corresponding to the detected key when a contact is detected by the contact detection means are disclosed.

  Patent Document 2 discloses an invention for selecting a wireless AP that is judged to have the highest communication efficiency by measuring the received signal strength from a wireless AP (access point) that is a selection candidate and the interference radio waves of its peripheral channels. Is disclosed.
