I will take a crack at it... just to make sure that My understanding is correct too.
In licensed radio world, the default lingo is as follows:- A single channel is actually two channels, one channel is used to Transmit and the other channel is used to receive. and each of these channels pair can be either in V polarity or H polarity (but not mingled). XPIC is used to describe a radio where you can mount two radios together, one using the H polarity and the other using V polarity, but the same channel... But still only one channel (H + V) is used to transmit and the other channel is used to Receive. (Thus Full duplex) MIMO...., = One Channel, both H & V polarities are used, and either one can be used for Tx and Rx (thus half duplex) AF11x = Traditional Licensed radio... one channel/polarity for TX and one channel/polarity for RX Mimosa B11 = Disruptive... a very odd animal... can be configured as... Use one channel (both polarities) for TX and one channel (both polarities) for RX or ... Use Two Channels, both polarities in each channel, and use either one to TX & RX (more like a dual channel MIMO) AF5 = Uses one channel (both polarities) for Tx and one channel (both polarities) for RX AF24 = can be used as One Channel (Dual Polarities) for TX and one Channel (Dual Polarities) for RX or can use the same one channel (dual polarities) for Tx and Rx.
