What’s the biggest source of QoE degradation in a WISP network?

With the exception of optimization gear, any equipment in your fixed wireless setup can negatively affect QoE. You obviously want to make sure you have sufficient backhaul capacity and the appropriate performance access points (APs). That said, every hop and buffer along the way can increase latency, limit bandwidth, and introduce packet loss.

This can happen at the transit point, your routers, backhauls, and your APs.

Learning from all of the Preseem deployments we’ve done, QoE degradation almost always comes down to the APs. There are exceptions, like backhauls with insufficient capacity or congested transit links. Most often, however, the most problems we have found are at the access points. 

For example, the performance between different APs, even if using the same model on one tower, can be very different. You can have very good latency numbers from one AP in one direction but the one next to it may have high latency and various QoE issues.

There are many different factors that can impact the QoE delivered by your APs. These include:

  • Congestion
  • Interference
  • Adverse weather conditions
  • Individual subscriber’s signal strength
  • Plan enforcement mechanism

The key is figuring out which APs have the issues, what the issue is, and knowing how to fix it.

Watch as Preseem co-founder and CEO Gerrit Nagelhout explains the biggest culprit leading to poor quality of experience (QoE) for WISP subscribers.
