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 […]

  Antennas are probably the most undervalued and poorly understood elements in WLAN networks. Many times, critical networks are designed with aesthetic aspects as the main driver. No wonder Wi-Fi network performance is such a disappointment in so many places. Radio wave propagation is a complex thing. Radio waves propagate, attenuate, reflect, refract, bend and […]

  This article on CNN’s website has some interesting views about Qualcomm’s recent announcement about MU-MIMO (multi-user-multiple input, multiple output) for tripling Wi-Fi speeds for patrons of coffee shops.  However, I noticed some information in the article that might set false expectations about how quickly these speeds are coming and how soon people will be […]

“Listen” to What Wi-Fi Networks Are Saying

|

  When people responsible for WLAN and Wi-Fi performance in their enterprise or institution hear about the 7signal platform, they immediately see the benefits of our active tests, but it takes a little longer for them to understand the power of 7signal’s passive testing. With active tests, the 7signal sensors “talk” to the network just […]

Meaningful Use for Hospital Wi-Fi

|

  Every time I talk to one of our hospital customers, I hear about meaningful use. The American Recovery and Reinvestment Act of 2009 provides for incentive payments for hospitals that adopt a certified Electronic Health Record (EHR) system and are meaningful users of certified EHR technology to improve patient care. Meaningful use has three […]

Is Network Performance Monitoring (NPM) hot again?

|

  Network Performance Monitoring (NPM) has been around for years, and it may be receiving extra attention again as organizations strive to improve productivity and use network capabilities as a competitive advantage. A good source for understanding trends is the studies that are published by TRAC Research. I find the data from their surveys to […]

  Last week, the IEEE802.11 had the official quarterly (plenary) meeting in Dallas.  Again, it was the 802.11HEW Study Group that garnered the most interest of all activity there. The HEW Study Group has been tasked to kick off standardization leading to a substantial increase in real-world throughput, and into instantly recognizable improvement in the […]
