Preseem Helping WISPs: New Mexico-based WISP Finds & Fixes Major Network Issue

Blog #1: Fixing a Network Issue


Roswell, New Mexico-based Wireless Internet Service Provider (WISP)

What Exactly Happened?

During a routine network check-up, Preseem helped identify that a particular site had experienced a sudden change in Quality of Experience (QoE) for users. This indicated a possible major network issue. The site was experiencing massive latency and delivering reduced bandwidth to subscribers. This signified that the site was down and subscribers were also experiencing poor QoE, as shown in the images below.

Image 2: Site 100 isolated with consistently high latency (implying that subscribers were also experiencing poor QoE)

Preseem then worked with the customer to investigate the site and identify the possible causes for this issue. Preseem was able to pinpoint the exact time when the issue started. Ultimately, the site had a power outage at that time and this explained such drastic performance issues. After the client rebooted all networking systems at the site, QoE performance went up as shown in the images below.

Key Takeaway

Real-time QoE monitoring allows WISPs to identify network issues proactively. This also allows them to take action to keep subscribers happy and avoid support calls and costs. It’s important to know if network elements are up or down (using traditional tools). However, it’s also critical for WISPs to know the quality of data being delivered to customers. This information is available through QoE-based monitoring platforms.

Preseem is a QoE monitoring and optimization platform developed exclusively for WISPs. Click here to book a demo with us today.
