gigahertz (GHz) is one billion Hertz. The standard US electrical power frequency is
60 Hz, the AM broadcast radio frequency band is 0.55-1.6 MHz, the FM broadcast
radio frequency band is 88-108 MHz, and wireless 802.11 LANs operate at 2.4
GHz.
SSID (Service Set Identifier)
SSID is a group name shared by every member of a wireless network. Only client
PCs with the same SSID are allowed to establish a connection. Enabling the
Response to Broadcast SSID requests option allows the device to broadcast
its SSID in a wireless network. This allows other wireless devices to scan and
establish communication with the device. Unchecking this option hides the SSID to
prevent other wireless devices from recognizing and connecting to the device.
