Embodiment Construction

[0012] Achieving sufficient antenna separation to support simultaneous operation on 2 VHF voice channels and 1 data link channel on a smaller aircraft is very difficult, if not impossible at all. Therefore, in the case of future plans to use both voice and data links for air traffic control communications, there is a need to design a method that makes it possible to support simultaneous voice on 3 or more VHF channels with less than 3 VHF antennas The need for devices that operate with data. On the other hand, larger aircraft have been able to support simultaneous operation on 3 VHF channels using 3 radio / antenna pairs. One of the benefits of using 3 radios, in addition to the ability to support simultaneous operation on 3 voice or data channels, is the ability to dispatch the aircraft in the event that one radio fails and still be able to support voice and data link communications . Therefore, while future aircraft designs will benefit and welcome the reduction in the numbe...

Abstract

A multichannel two antenna radio unit device comprising a left very high frequency (VHF) radio and a right VHF radio is provided. The left VHF radio unit comprises a left VHF radio transceiver, the left VHF radio transceiver comprising a left wideband multi-channel receiver configured to receive voice channels and data channels in an aeronautical VHF communication band, the left VHF radio configured to communicate on at least two voice channels and at least one data channel. The right VHF radio comprises a right VHF radio transceiver, the right VHF radio transceiver comprising a right wideband multi-channel receiver configured to receive voice channels and data channels in an aeronautical VHF communication band, the right VHF radio configured to communicate on the at least two voice channels and the at least one data channel, and communicatively coupled to the left VHF radio unit via a bi-directional serial bus.

Description

technical field [0001] The present application relates to a reduced aircraft VHF communication antenna using a multi-channel VHF radio. Background technique [0002] A cellular radio base station is capable of supporting two-way communication with multiple mobile users on multiple channels simultaneously using a single antenna without interference between channels. Avoidance of cross-channel interference is possible because these cellular radio frequency bands are divided into separate frequency bands for transmission and reception (known as frequency division duplex operation), or the same frequency band and channel are used for transmission and reception but the channel is divided Divide into time-synchronized transmit and receive slots so that all channels transmit or receive simultaneously (known as time-division duplex operation). By designing the cellular system so as to avoid mutual interference, cellular radio base stations can transmit and / or receive simultaneously...
