Embodiment Construction

[0039] Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

[0040] When redundancy of communication is realized by using a frequency band such as the ISM (Industrial Science Medical) band (band) of the so-called 2.4 GHz frequency band, there is a side lobe (Side lobe) of the transmission wave emitted from one communication circuit and is input as an interference wave to the other party. There is concern about the other communication circuit that is placed close to the one communication circuit.

[0041] At this time, when the radio wave intensity of the side lobe of the interference wave is higher than the radio wave intensity of the frequency main lobe (Main lobe) that the communication circuit should receive, there will be a problem that normal reception cannot be performed.

[0042] The wireless communication device of the present invention cuts off the specific frequency components of the side lobes of the fre...

Abstract

The invention provides a wireless communication device and a wireless communication system using the same. The device is capable of avoiding communication interruption caused by multipass fading witha compact and inexpensive configuration. The wireless communication device includes a first transceiver which performs communication by using each of a plurality of channels contained in a first frequency band, a second transceiver which performs communication by using each of a plurality of channels contained in a second frequency band that is higher than the first frequency band and separated from the first frequency band through a separation band having a predetermined frequency span, and a control device connected to the first transceiver and the second transceiver capable of communicatingwith the first transceiver and the second transceiver, selects one channel from the plurality of channels of the fist frequency band and one channel from the plurality of channels of the second frequency band to set a channel pair including a pair of channels, and causes the first transceiver and the second transceiver to communicate the same data by using the set channel pair.

Description

technical field [0001] The present invention relates to a wireless communication device and a wireless communication system using the wireless communication device. Background technique [0002] Conventionally, in wireless communication, there is a problem that communication is interrupted due to interference caused by multipath fading (Multipass Fading). As a device for avoiding communication interruption due to multipath fading, for example, the following device is disclosed: the device is an interference canceling device for canceling interference among a plurality of signals simultaneously transmitted from a plurality of transmitting antennas And be received by a plurality of receiving antennas at the same time, the device has a plurality of interference cancellers, at least one interference canceller corresponds to each signal to be sent, each interference canceller receives a signal from each receiving antenna, and each interference canceller outputs a signal correspon...
