Solved: Guest Wireless bleeding outside into parking lot

farhanegal77 · ‎03-02-2016

I am experiencing an issue where our guest SSID is broadcasting and bleeding out the building. It was reported that people in the parking lot can access our guest network. Below are my questions:

1. How do I block the Wireless signal travelling outside the building.?

2. how secure is this capwap encryption? what protocols does it use?

appreciate in advance any feedback.

1. one option is to reduce the TX power, it will reduce the coverage area.

the transmitted power is reduced to limit the effect of RF interference. The reduction has a negative effect on the radio coverage. The transmitted power is directly proportional to the radio coverage area. Therefore, the weaker the transmitted power, the smaller is the radio coverage area.

2. Capwap is the communication between access point and WLC for data encryption .
