Metageek Eye PA Review

I like pictures of stuff. Some people understand and learn more easily through hearing the spoken word, some through reading text and others prefer pictorial representations of ideas, concepts and information. For me, it's definitely pictures, which is why I love Metageek's Eye PA product. In this article, I take a look at the Eye PA wireless network analysis tool and talk about why I'm so enamored with this product.

If you're like me, one of the first things you do when visiting a new building, venue or customer site is to fire up your copy of Metageek's free (and incredibly useful) WiFi tool: inSSIDer. It's always interesting to see just how many SSIDs organisations are still trying to cram on to the 2.4GHz band or are perhaps creating themselves and their neighbors a whole heap of trouble by not using non-overlapping channels. Here's how things look for me, sat at home, as I write this article:


However, I now have an additional habit when visiting a new …

How Fast Is My iPad on WiFi?

I recently had an interesting customer WiFi performance issue to investigate which turned out to be a whole host of issues on the 2.4GHz band that he was using for his WiFi network. His issues were solved by moving his clients (iPads in this case) across to the 5GHz band, which instantly gave much higher throughput and reliability.

However, when he was testing his much-improved network by doing some throughput testing with an iperf server, I noted a sound of disappointment in his voice when he said that he couldn't get a throughput greater than 35Mbps on his iPad.I told him that this was, in  fact, as good as it was ever going to get when using an iPad, even with high performance 802.11n access points.

I thought it might be useful to have a look at what realistic throughput figures might be for an iPad on a WiFi network when using 802.11n access points, and why we hit much lower throughput figures than we might expect from the AP manufacturer data sheets.

I set up my home lab with…
