what are wifi firewalls?
Adding a Wi-Fi firewall to your network wifi firewalls Deploying a Wi-Fi firewall involves installing a central server in your NOC and positioning remote sensors throughout the offices ("air space") to be monitored. Sensor network planning is essential to avoid coverage holes in locations like stairwells where intruders might lurk unobserved. Most appliances use overlay networks of dedicated sensors. Some can also use regular APs that watch for rogues in their spare time. Dedicated sensors have better observation and prevention capabilities, but require more up-front investment to purchase, mount, power, and cable. Sensors that support Power over Ethernet and/or daisy-chaining can reduce that cost. Communication between remote sensors and the central server usually requires modest bandwidth, but a large remote office with limited WAN access may deserve its own server.
