Embodiment 1

[0016] figure 1 It is a schematic configuration diagram showing a wireless communication device according to Embodiment 1 of the present invention.

[0017] The wireless communication device is roughly divided into: a transceiver unit 1, which performs transmission and reception with other wireless communication devices according to a radio frequency; and a data processing unit 2, which performs data transmission and control and controls the transceiver unit 1.

[0018] The transceiver unit 1 includes a radio frequency unit 10 including an antenna, an electric field intensity measurement unit 20 , a demodulation unit 30 , a modulation unit 40 , a determination unit 50 , a reception control unit 60 , a transmission data storage unit 70 , and a timing control unit 80 .

[0019] The high frequency unit 10 is composed of a receiving unit and a transmitting unit which are not shown. The receiving unit selects and amplifies the frequency component of the designated receiving channe...

Embodiment 2

[0047] image 3 is a configuration diagram showing the outline of a wireless communication device according to Embodiment 2 of the present invention, and figure 1 The elements common to the elements in are given common symbols.

[0048] The wireless communication device is figure 1 A power-saving control unit 90 is added to the transceiver unit 1 of the wireless communication device, and a clock source 3, a clock supply unit 4, and a power supply unit 5 controlled by the power-saving control unit 90 are provided. Other structures are the same as figure 1 same.

[0049] The clock source 3 is a clock generation source other than the transceiver unit 1 and the data processing unit 2, and is composed of a crystal resonator or a crystal oscillator, and generates a master clock MCK. The clock supply unit 4 supplies clocks to each part of the transceiver unit 1 based on the master clock MCK supplied from the clock source 3, and can supply a required clock frequency (for example, h...

Abstract

An object of the present invention is to reduce power consumption of a wireless communication device. When the electric field intensity RSSI is measured in the electric field intensity measuring section (20) at the time of transmission, and the value is equal to or less than the reference value, the transmission permission signal TXE is supplied from the determination section (50) to the data processing section (2) etc., and the transmission data TXD is output. . In addition, at the time of reception timing, the electric field strength RSSI is measured in the electric field strength measuring section (20), the value of which exceeds the reference value and the reception data RXD demodulated by the demodulation section (30) is judged in the reception control section (60) When it is normal, the received data RXD is supplied to the data processing unit (2) together with the received data signal RDE. As a result, the data processing unit (2) is not activated except when necessary, so power consumption can be reduced.

Description

technical field [0001] The present invention relates to low power consumption of wireless communication devices. Background technique [0002] The wireless network is used for data communication between a base station and multiple wireless terminals existing in the area covered by the base station. The base station starts the receiving operation at a certain time, and receives the data transmitted from the wireless terminal side within the time. Also, when transmitting data from the base station to the terminal device, the data is transmitted after confirming that the wireless terminal has not transmitted data for a certain period of time. Likewise, on the wireless terminal side, the receiving operation is started every predetermined time, and the data transmitted from the base station side is received within the time. Also, when data is transmitted from the terminal device to the base station, the data is transmitted after confirming that the base s...
