ISO 2.4 GHz Hell Holes

[TyFord]

I'm looking for places to stress test some audio gear that runs up there.


It has Frequency Diversity that sends uncompressed 24-bit, 48 kHz mono audio on two dynamically allocated frequencies, each of which change quickly and inaudibly because the transmitter and receiver are duplex and are constantly talking to each other. It has Time Diversity that sends the audio in multiple time slots. Sort of like the redundancy scheme offered by DAT machines, but in the air, not on tape. It has Space Diversity using two antennas on both the transmitter and receiver. Latency is about 3.8 mSec.

So, where are the best 2.4 GHz Hell Holes? Maybe a Pandora? Starbucks? On the floor at NAB?

Suggestions.

Thanks,

Ty Ford

The trade show floor at NAMM and a Starbucks in Manhattan both come to mind. Also, any large live concert with thousands of smart phones pinging every WiFi network in the vicinity.

The last time I attended Interop, next one is March 31-April 4 2014, I found that the entire 2.4 spectrum was 'locked' by all the devices in the place. I didn't have at the time my current 'widget' that allows me to use 802.11 at 5 MHz bandwidth, which doesn't do anything for the 'noise floor', but may allow signaling where other 20/40 MHz devices are being held off because they detect packets flying through the air.

I recently had a shoot on the observation deck of the empire state building. I wasn't doing anything wireless but had my rode videomic plugged into my DSLR (suffice it to say audio was not a concern). After playing back my footage I noticed a crazy hum coming from the audio and realized it must have been interference from the broadcasting antennas. My 5D II auto levels wouldn't work for a little while after that (not sure if that was the reason or not.) Now everything works again.
