About four years ago, the IT department at UTK was asked to provide temporary Wi-Fi outdoor coverage in a parking lot to support online payments for the Volapalooza event! The cost of an outdoor rated AP was a definite show stopper for the student committee’s budget. So we improvised a PVC electric box completely sealed and we stuck an Aruba AP-105 in it connected with Cat5, thinking that it would last for the week end and perish from its natural electronic death during the summer from extreme temperatures (the box is exposed to the sun from about 10 am till 1 pm). It was an experiment. We don’t have the extreme temperatures of Houston, but Knoxville-TN does have its fair share of extreme temperatures. I pass by the AP on a regular basis, and it’s still spewing 802.11 frames at a decent rate! A testimony to the resilience of electronics!
