Recently our team received word that several clients in a classroom where disconnecting while doing online benchmark tests. The clients will rename nameless but were of the “lower end” variety. These clients were single band 802.11n devices which have had a bad track record of reliability, no matter what the…
What NetBeez Does NetBeez captures network and application performance (e.g. latency increase) from the user perspective on wired and wireless networks. Sensors at each network location run tests and simulate the user experience. We have dozens of demo NetBeez agents deployed around the country and the world and we collect…
Supporting people who work from home is something I can relate to since I’ve been one of those employees for more than a year now. I work from my home in San Jose, CA and the rest of the NetBeez team is in Pittsburgh, PA. Being a technical person, I…
Multiple Input Multiple Output (MIMO) routers have become the standard in commercial and consumer WiFi. However, combining optimally multiple wireless signals in order to achieve higher data transfer rates is a challenging problem for dynamic and crowded wireless environments. The good news is that an MIT group has demonstrated significant…
A couple of months ago I blogged about using a Raspberry Pi as home network monitoring agent. The idea was to collect data from home networks and compare the performance of different ISPs as well as detect outages and be notified about them. Guess what? There is nothing new under…
On April 14th, I presented Distributed Network Monitoring for Wireless Metropolitan Networks during Mobility Field Day 1.Mobility Field Day is a two-day live-streamed event on wireless mobility organized by Stephen Foskett and his group. You can watch the recording of the video here. In my presentation, I first talked about…
Between the 3rd and the 8th of April 2016, the Internet Engineering Task Force (IETF) group met in Buenos Aires, Argentina. Bill Jensen and James Dishongh are two of the network engineers involved in the design and deployment of the network infrastructure that provided wired and wireless connectivity to the…
There are more than 8 million Raspberry Pis around the world, and at least a million in the US (I don’t have numbers, but I think this is a safe assumption). In a previous post, I described how to use a Raspberry Pi to monitor your parents’ home network. But…
