The App

Building Reliable Network Infrastructure

Get the right software for the job— crafted for professionals who outgrew iPerf.

Here’s what you can do with Tessabyte:

Wi-Fi Speed Tests: Test wireless networks for throughput and reliability.
Network Capacity Tests: Assess the maximum data transfer rate that a network link can support.
Link Quality Analysis: Determine the quality of individual network links.
Stress Tests: Simulate high traffic loads and observe how the network behaves under congestion.
Quality of Service (QoS) Assessment: Evaluate how different traffic types are prioritized in the network.
Firmware and Hardware Updates Validation: Verify the impact of network device firmware or hardware upgrades.

LAN Bandwidth Tests: Don't take your local network speed for granted. Test, verify, and monitor.
Network Topology Planning: Understand how network design choices impact performance.
Comparative Benchmarking: Compare the performance of different network components or analyze how your network behaves at various times of the day.
Security Assessment: Evaluate the impact of security measures on network performance.
Load Balancing Verification: Test the effectiveness of load balancing in a network.
SLA Compliance Verification: Ensure that the network meets its Service Level Agreements.

Association limits, airtime, and contention determine real Wi-Fi client capacity

Wi-Fi Capacity: How Many Active Clients Can an Access Point Really Support?

How many Wi-Fi clients can a single access point really support? The answer isn’t as simple as a number. In real networks, every device competes for the same airtime, and as more clients join, each gets a smaller slice of the pie. In this article, we look at how Wi-Fi capacity actually works — and why adding “just a few more devices” can quickly turn a fast network into a slow one.

A Wi-Fi 7 reality check for offices and schools

The Wi-Fi Test That Passes in the Lab and Fails in the Real World

If you have ever validated a Wi-Fi upgrade in a quiet lab and then spent the next week explaining to users why “everything looks fine on our end,” you already know how this story ends. The lab test measured the PHY at its best. The real network lives and dies by airtime. This post is for Wi-Fi engineers. It is about understanding why that number collapses at 10:30 AM on a Tuesday, and how to test in a way that predicts what users will actually experience.
