B . 2200 packets per second and 20% bandwidth for HMI and maintenance traffic
C . I/O control traffic can be run on 2.4 or 5 GHZ channels
D . I/O control traffic should be run on 5GHZ channels only
E . Standard I/O RPIs less than 20ms are not practical for wireless media because the maximum latency and jitter become comparable or greater than the RPI
F . Standard I/O RPIs less than 10ms are not practical for wireless media because the maximum latency and jitter become comparable or greater than the RPI
