So, you’ve built your predictive design and now it’s time for the rubber to meet the road – the infamous AP-on-a-Stick survey. To perform this piece of your wireless design you’ll need a lot of “unique” gear… tripods, laptop shelves, tons of wireless adapters, APs, and enough battery power to get you through the day.
When I was building out my survey kit, I noticed one flaw with the “professional” battery packs built for wireless surveys. Beyond being very bulky and expensive, the majority of them only support 802.3af. The newer and larger APs often prefer 802.3at (also called PoE+) these days. In some cases, they can use 802.3af, but they turn off several spatial streams in the 2.4GHz radio to adjust for the lack of power.
That’s less than ideal, isn’t it?
Thanks for the Internet, I was able to cobble together a pretty affordable battery pack that supports both 802.3af and 802.3at and lasts an incredibly long time. Here’s the pieces and parts that have worked for me:
The total will run you about ~$140.00 and it lasts for an extremely long time. Just power up the Intocircuit, hook it up to the Tycon converter using the adapter, and connect your AP. I’ve used it for several gigs now and despite looking a little “homemade,” it does the trick.
