AI Technical Summary

Technical Problem

Existing communication devices experience prolonged waiting times during wireless communication scans to select a communication carrier, which delays data transmission.

Method used

A communication device equipped with a wireless communication module and a microcomputer that instructs the module to scan multiple frequency bands. When data transmission is necessary, the microcomputer waits for a scan of an unsampled frequency band and initiates data transmission via the wireless communication module.

Benefits of technology

This approach significantly reduces the waiting time for data transmission by allowing immediate data delivery once a suitable frequency band is scanned, enhancing the efficiency of wireless communication.

Abstract

To shorten a waiting time for data transmission while scanning wireless communication for selecting a communication carrier.SOLUTION: A communication device 100 is provided that includes a wireless communication module 121 for communicating with a server 400 via a base station 300 of a communication carrier, and a microcomputer 110 for instructing the wireless communication module to scan a plurality of frequency bands. When the need for data transmission arises, the microcomputer causes scanning of frequency bands that have not yet been scanned to wait for, and transmits data via the wireless communication module.SELECTED DRAWING: Figure 4
