Title:
RADIO COMMUNICATION EQUIPMENT AND INFORMATION PROCESSING UNIT
Document Type and Number:
Japanese Patent JP2002204178
Kind Code:
A
Abstract:

To switch a plurality of communication system with a simple and low-cost constitution when the plurality of communication systems are supported and to control a power suitable for each communication system.

An antenna position detector 41 detects the length of the antenna 21 when the antenna is extended or contracted or the position of the antenna 21 when the antenna 21 rotated around an axis. A CPU 43a in a communication controller 43 decides the communication system by referring to a table 44a based on the length or the rotating position of the antenna 21 detected by the detector 41, loads a code corresponding to the system from a memory 44 and executes the system. The CPU 43a also instructs switching of an amplifier 42b to a radio communication I/F 42 and controls the power corresponding to the system. Thus, the systems can be dynamically switched by such simple operation as transferring of the antenna 21 for radio communication. The CPU 32a also control the power suitable for the system at that time and can suppress a wasteful power consumption.
