Posted by Louise Peter on Oct 31, 2017

It is a classic urban legend horror scene - a young woman is home alone (she is usually a babysitter). She receives creepy phone calls asking "Have you checked the kids?" The babysitter calls the police and the police set up watch outside the house to keep the babysitter safe. The police trace the phone calls and to their horror, they discover that the calls are not coming from another location, but they are coming from inside the house.

Radio Resource Management That Never Sleeps
Posted by Sriram Venkiteswaran on Jul 16, 2016

RRM (Radio Resource Management) is a collection of techniques in which access point radios continuously analyze the RF spectrum to do the following:

  1. Adjust the operating channel to mitigate co-channel interference.
  2. Adjust the operating power to optimize coverage.
  3. Provide coverage hole protection by automatically increasing the power when neighbor APs fail.
  4. Ensure clients are evenly load-balanced between the APs, between channels, and between bands.
  5. Ensure clients are connected to the best possible access points (address “sticky client” behavior) by steering them to the right access point.
  6. Ensure air time fairness by making sure less-capable clients do not consume excess bandwidth.
