摘要： A wireless communication authentication program whereby a slave station in a small-scale wireless LAN system can be authenticated by a simple procedure. A wireless communication authentication device periodically increments a first system timer value (Step S1) for which an optional numerical value is set beforehand. A wireless communication device sets therein a second system timer value (Step S2) so as to coincide with the first system timer value and periodically increments the second system timer value (Step S3). The wireless communication device transmits an authentication request command including a third system timer value (Step S4), and the wireless communication authentication device compares the third system timer value included in the authentication request command with the first system timer value thereof assumed at the time of reception of the command (Step S6). In accordance with the comparison result, the wireless communication authentication device determines whether to authenticate the wireless communication device.

摘要： If a radio LAN apparatus moves from a communication range of a first access point to a communication range of a second access point, and if communication link between the radio LAN apparatus and the first access point is broken, a memory control section stops transmitting data to the first access point. At this time, data to be transmitted to the first access point are not deleted from memory. After the radio LAN apparatus enters the communication range of the second access point, the memory control section resumes transmission of the data stored in the memory. Thereafter, the next data are transmitted. Thus, the data is transmitted in proper sequence.

摘要： A control status monitor/decision unit is added to a transmission power control apparatus which determines a transmission power level of a transmission signal to be output from an antenna via a transmission system and controls the same by referring to a received signal from the antenna obtained via a reception system. The unit monitors the control status in the control apparatus and performs the control of the optimum transmission power level according to this control status. By this, a further higher channel quality than that of the conventional apparatus can be maintained.

摘要： A transmission power control apparatus in a communication apparatus which synthesizes IF signals output from a plurality of channel units and emits the synthesized signal from an antenna. In the transmission power control apparatus, when none of channel units transmit an IF signal, a controller changes the connection of a power amplifier from the antenna over to a dummy antenna and supplies the output of the power amplifier to the dummy antenna, and instructs a predetermined number m of channel units to output IF signals, a reference voltage generator generates a reference voltage corresponding to a transmission wave number m, and a variable attenuator or a variable amplifier controls gain so that the difference between detected voltage corresponding to a transmission power and the reference voltage becomes zero.
