@asyal, thanks for the Stack Exchange link it is defiantly useful for simulating the low/bad cell signals and I think we need to consider getting an enclosure for more detailed testing.
That said I was hoping for a way to issue a command on the target that would simulate a network drop out which would result in calls to the AirVantage session handlers. Once I test this I would then like to restore the network and watch the system behaviour. (I have changed the post subject to better reflect my request)
Any way to do this without attenuators and/or an RF enclosure?
