Use MOS Score to Troubleshoot Voice Over Wi-Fi

The quantitative assessment of the quality of Voice Over Wi-Fi communications is often measured by its MOS score (Mean Opinion Score). The MOS score ranks the quality based on a number in the range of 1 to 5. The original idea behind the MOS score was to take the mean average of all the individuals rating the quality of a test call. That soon changed, as modern network analyzers can calculate MOS ....Read more

Differences Between TCP and UDP

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are the most common network protocols used in network device communication today.The connection-oriented TCP was developed first and is more common, as it guarantees delivery and accuracy of the data transmission. The protocol tracks and acknowledges all information sent between two devices, and if data is lost or corrupted durin....Read more

Problem: Wireless AP Won’t Join Controller

If you are having problems with wireless AP’s not joining the controller check the following:• Verify that both the power and ethernet link lights are ON at the wireless AP.• Verify switch port to router is Trunked!• Verify switch port to wireless AP is Trunked!• Make sure the wireless AP installer has NOT plugged the RJ-45 into the console port of the AP.• If the switch is not directly connected ....Read more

The Physical Layer Matters

We are in the networking age of multi-gigabit wireless connections. Lightning-fast Wi-Fi technologies move data from one place to another, routing business-critical traffic at speeds never imagined. There is, however, a critical component to the system that network engineers of today often overlook: the physical layer. Wireless connections are carrying an unprecedented traffic load from one device....Read more

Documenting Your Wi-Fi Network Doesn't Have to be Painful

It’s true that Wi-Fi network documentation isn’t the most fun thing to do. In fact, it can be such an eye-rolling task that engineers in many organizations avoid it until necessary. In some cases, documentation is considered a low priority task – until a problem strikes. When troubleshooting a critical problem, good Wi-Fi network documentation can mean the difference between quick resolution and c....Read more

I Want to Upgrade to 802.11ax. Can I Just Buy and Install Some APs?

There is an important migration path if your organization is considering the implementation of 802.11ax. With this new wireless technology, the benefits are huge in terms of user capacity and bandwidth per user. However, these gains can only be realized if 802.11ax is properly implemented. It’s not as simple as just buying APs and lighting them up.While 802.11ax can co-exist with older technologie....Read more
