Concession reviews are undertaken every five years, and it was between two review dates that Kevin Lindsay, Business Systems Support Analyst for Merseyrail became aware of the spike in passenger demand for WiFi access and recognized that something had to be done.

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.
