10BASE-T
IEEE 802.3-2005 specification for 10 Mbps Ethernet over two pairs of Category 3 or
better UTP cable.
100BASE-TX
IEEE 802.3-2005 specification for 100 Mbps Fast Ethernet over two pairs of
Category 5 or better UTP cable.
Access Point
An Wi-Fi internetworking device that seamlessly connects wired and wireless
networks.
Authentication
The process to verify the identity of a client requesting network access.
Auto-Negotiation
Signalling method allowing each node to select its optimum operational mode
(speed and duplex mode) based on the capabilities of the node to which it is
connected.
Base Station
A WIMAX service provider’s equipment that is installed at a fixed location to provide
network connectivity for subscriber stations within a defined service area.
Beacon
A signal periodically transmitted from a Wi-Fi access point that is used to identify the
network and maintain contact with wireless clients.
Carrier-to-Interference-Plus-Noise Ratio (CINR)
A measurement of the channel quality in a WiMAX link. Subscriber stations measure
the received CINR and send the information back to the base station. The base
station can then adjust modulation and coding for the link to optimize throughput.
Center Frequency
The radio frequency at the center of a WiMAX channel. WiMAX channels can be of
different widths (the channel bandwidth) and the transmitted radio signal is spread
across the full width of the channel.
Channel Bandwidth
The range of frequencies occupied by a WiMAX radio signal. The amount of
information that can be transmitted in a radio signal is related to the channel
