Ann, a small business owner, would like to implement wireless networking for her business but wants to be sure the wireless is ONLY accessible from within her business' premises. Which of the…

Disabling SSID broadcast hides the network name from casual discovery but does not prevent signal propagation; the network remains detectable and joinable with basic wireless scanning tools.

Unidirectional antennas emit radio frequency energy in a focused beam or limited arc, allowing signal to be directed inward and away from exterior walls. Simultaneously reducing transmit power ensures the signal does not propagate beyond the physical boundary of the premises, effectively preventing outside users from detecting or connecting to the network.

Shorter DHCP lease times control IP address assignment duration and have no effect on the physical range or geographic reach of the wireless radio signal.

Omni-directional antennas broadcast signal equally in all directions including outward through exterior walls, making signal containment to the premises much harder even with reduced power.
