Radio Frequency (RF) Terms: GHz, MHz, Hz
The international unit for measuring frequency is Hertz (Hz), equivalent to the
older unit of cycles per second. One megahertz (MHz) is one million Hertz. One
gigahertz (GHz) is one billion Hertz. The standard US electrical power frequency is
60Hz, the AM broadcast radio frequency band is 0.55-1.6MHz, the FM broadcast
radio frequency band is 88-108MHz, and wireless 802.11 LANs operate at 2.4GHz.
SSID (Service Set Identier)
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.
Station
Any device containing IEEE 802.11 wireless medium access conformity.
Subnet Mask
A subnet mask is a set of four numbers congured like an IP address. It is used to
create IP address numbers used only within a particular network.
TCP (Transmission Control Protocol)
The standard transport level protocol that provides the full duplex, stream service
on which many application protocols depend. TCP allows a process or one
machine to send a stream of data to a process on another. Software implementing
TCP usually resides in the operating system and uses the IP to transmit information
across the network.
WAN (Wide Area Network)
A system of LANs, connected together. A network that connects computers located
in separate areas, (i.e., different buildings, cities, countries). The Internet is a wide
area network.
WECA (Wireless Ethernet Compatibility Alliance)
An industry group that certies cross-vender interoperability and compatibility of
IEEE 802.11b wireless networking prod WPA (Wi-Fi Protected Access)
