3.6GHz 802.11y for Competitions

Even if FIRST reduces each field to a single channel and makes the field/robot system more stable the effect of reusing a channel will be degraded performance with one or more network.

Once the other network is out of FIRST's control the risk of channel monopolization is high.

As we have both stated putting the show stopping robot communication on a different channel is possible. That other channel should be easier to diagnose without robots of various different needs placing demands on it. The field systems are common and required for all fielded robots. TCP/IP and video is not required but nice to have.

On the topic of 3.6GHz it only perpetuates binding the necessary field communications to the extra optional traffic.
It would be far cheaper to use RS232/TTL serial to RF adapters for the field traffic.
Licensing issues may apply to both options.

Course we could try IRDA for the fields and make the fields more RF immune.
