Detailed Description

Spectrum Wifi Phy Multiple Spectrum Test.

This test is testing the ability to plug multiple spectrum channels to the spectrum wifi PHY. It considers 4 TX-RX PHY pairs that are independent from each others and are plugged to different spectrum channels that are covering different frequency range. Each RX PHY is also attached to each of the other 3 spectrum channels it can switch to.

In the first scenario, we consider the default case where each TX-RX PHY pairs are operating on different frequency ranges and hence using independent spectrum channels. We validate that no packets is received from other TX PHYs attached to different spectrum channels and we also verify the amount of connected PHYs to each spectrum channel is exactly 2. The test also makes sure each PHY has only one active spectrum channel and that the active one is operating at the expected frequency range.

In the second scenario, we consecutively switch the channel of all RX PHYs to the one of each TX PHY. We validate that packets are received by all PHYs and we also verify the amount of connected PHYs to each spectrum channels is either 5 (1 TX PHY and 4 RX PHYs) or 1 (the TX PHY left alone).
