I recently had an encounter at my day job that left me staggered. There was a network outage at one of our locations. Our WAN is a VLAN leased from a wireless ISP, or WISP. We had some power outages over the weekend in the area, so when the network was down on Monday morning, […]

Power Matching: Transmit Power, or EIRP?

This question has come up on Twitter in the past, and is something I have needed to have clarified for myself previously. I am referring to power matching between access points and clients.

Short Point-to-Point Upgrade
