RF automation comparison

A Data-Driven Comparison of Cisco and Aruba’s RF Automation – Part 2

by Veli-Pekka Ketonen

In part 1 of our blog on RF automation, we began to compare Cisco and Aruba’s RF automation features using 7signal’s system of Sapphire Eyes and Mobile Eyes for Wi-Fi performance Management. We looked at power levels and channel balance. Today, we are going to continue our comparison by taking a closer look at channel stability, Read More

RF Automation showdown

A Data-Driven Comparison of Cisco and Aruba’s RF Automation – Part 1

by Veli-Pekka Ketonen

Wi-Fi RF automation is a hot topic. Not because it’s new (it’s not) but because there are strong believers and non-believers. The discussion lacks facts and measurement data, which we will cover in this 2-part blog. 7signal worked in cooperation with Avans University of Applied Science to characterize 802.11ac Wi-Fi performance and behavior in their environment.

Wi-Fi roaming issues

Get Help with Wi-Fi Roaming Issues

by Veli-Pekka Ketonen

Wi-Fi roaming issues are frustrating and often relate to a few key things, such as poor network design, where there is excessive cell overlap due to high access point power levels. As a result, client devices “stick” to the distant cell. Another culprit of Wi-Fi roaming issues is RF bleeding between floors, where clients connect to an access Read More

Wi-Fi beacon

Controlling Beacons Boosts Wi-Fi Performance!

by Veli-Pekka Ketonen

No matter what kind of Wi-Fi access point you have, it sends beacons. Beacons consume airtime and erode the capacity of your network. Configuring your beacons properly has a significant impact on how your network performs.

Why I Started 7signal – The Need For Speed

by Veli-Pekka Ketonen

Looking back, my life seems to be defined by two things: going faster and getting better. When I was growing up I was a race kart driver and almost every weekend my father and I drove to different cities in Finland to compete. We went to races in other countries in Europe too. The best Read More

WLAN Spectrum Analysis: Proactive vs. Reactive

by Veli-Pekka Ketonen

Spectrum analysis is a layer 1 technology for identifying presence, type, level and location of RF interference. Today’s wireless access point integrated spectrum analysis functionality does not run continuously, which is a significant limitation. Integrated spectrum analyzers commonly use the same radio chip for WLAN spectrum analysis and for serving client devices. For this reason, Read More

Success Story: Improve WLAN by Identifying 2G, 3G and 4G Network Interference

by Veli-Pekka Ketonen

This may come as a surprise to many experts, but mobile networks generate interference to WLAN networks and may clearly degrade WLAN performance. Most would not think to consider this as a relevant source of Wi-Fi interference, however, I explain below how we identified the issue and got one organization back on the path to Read More
