A Preseem Success Story

Alamo Broadband

Learn how this Texas WISP fixed their Bufferbloat issues, reduced ‘internet is slow’ calls, and improved subscriber quality of experience.

Meet Alamo Broadband

With an extensive technical background in network coding, Joe Portman, President of Alamo Broadband, founded his fast-growing WISP in Elmendorf, Texas over seven years ago.

Joe had been researching Bufferbloat and looking for ways to measure and reduce the latency it caused in his network when he discovered Preseem and soon became an early adopter of the QoE platform.

Hidden Latency Was Driving “Slow Internet” Complaints

Before deploying Preseem, Alamo suspected Bufferbloat was contributing to the growing number of “my internet is slow” complaints from subscribers. Those concerns were quickly confirmed.

Large, unmanaged packet buffers, known as Bufferbloat, can create significant latency when a connection approaches capacity. The result? Customers experience sluggish performance, poor video calls, buffering, and frustrating slowdowns even when they have enough bandwidth available.

For WISPs, two common causes of poor subscriber experience are congested access points (APs) and traditional plan enforcement solutions that rely on simple queues. Without detailed visibility into Quality of Experience (QoE), identifying these issues and knowing where to take action can be challenging.

Using QoE Insights to Eliminate Network Bottlenecks

Preseem provided Alamo with the detailed QoE visibility needed to pinpoint exactly where customers were experiencing issues, including specific APs and backhaul radios contributing to poor performance.

With this insight, Joe was able to address the underlying network problems through targeted upgrades and frequency changes to reduce interference. The before-and-after results clearly showed the impact of these improvements, with significant reductions in latency and a better subscriber experience.

After resolving lower-level QoE issues, Alamo replaced its Mikrotik-based plan enforcement solution with Preseem’s QoE Optimized Plan Enforcement. Unlike traditional deep queues that can introduce unnecessary latency under load, Preseem uses modern Active Queue Management (AQM) techniques to maintain performance while enforcing subscriber speeds.

The transition was simple through Preseem’s Sonar integration, requiring only a configuration change without duplicate data entry or additional operational complexity.

The result was immediate and measurable: lower latency, improved throughput, fewer support calls, and happier customers. By combining actionable network insights with intelligent traffic management, Preseem helped Alamo deliver a consistently better Quality of Experience across the network.
