Is there is a standard cabling impedance for coax cable connecting access points to antennaÃ¢Â€Â™s. I have read that the cabling can be 50 ohms or 75 ohms. Which is current?
Most WLAN gear is terminated in 50 ohms. There are exceptions, but not many. It's important to make sure that your AP/Bridge, Cable, Connectors, Antennas, and anything else in the signal path has the same impedance - regardless of what the impedance is.
