Radio Settings - Enable Frame Burst & Beamforming?

  • Question
  • Updated 3 years ago
These two settings in "Radio Profiles" have no corresponding help doc yet.
  Enable Frame Burst (AP230/AP1130/AP130) 
  Enable Transmit Beamforming (AP230/AP1130/AP130)
These are not enabled by default. What is the potential disadvantage to enabling these?  Is it simply a risk of overloading the CPU? 

We have mostly AP230's and AP1130's in both indoor and outdoor settings.  We have two use cases: a) up to 70 clients (mostly smart phones) per 5.8GHz radio of lighter http traffic; and b) 10-20 clients per 5.8GHz radio of busy http use including video streaming (smart phones, tablets & laptops).

Explicit Transmit Beamforming requires client support. There is an airtime overhead sending the sounding/calibration frames and there is not yet sufficient client support to make this worthwhile, a net performance win, in the vast majority of deployment scenarios. That dynamic is likely to change in the future as older clients are replaced. For now, it's disabled by default therefore.

Frame Bursting also requires client support and there could be compatibility implications enabling it, it's not yet widely used. There's a discussion here you may be interested in: https://community.aerohive.com/aerohive/topics/ap230_frame_bursting_is_it_an_unicorn
