RADIUS

Remote Authentication Dial-In User Service. An authentication and accounting system

used by many Internet Service Providers (ISPs). When you dial in to the ISP, you must
enter your username and password. This information is passed to a RADIUS server, which

checks that the information is correct, and then authorizes access to the ISP system.

Radius typically uses port 1812 and port 1813 for authentication and accounting port.

Though not an official standard, the RADIUS specification is maintained by a working group
of the IETF.

Receiver Sensitivity

Receiver sensitivity means how sensitive is the radio for receiving signal. In general; the

slower the transmission speed, the more sensitive the radio is. The unit for Receiver
Sensitivity is in dB; the lower the absolute value is, the higher the signal strength. For

example, -50dB is higher than -80dB.

RJ-45

Standard connectors for Twisted Pair copper cable used in Ethernet networks. Although

they look similar to standard RJ-11 telephone connectors, RJ-45 connectors can have up to

eight wires, whereas telephone connectors have only four.

Router

An IP sharing router is a device that allows multiple PCs to share one single broadband

connection using NAT technology. A wireless router is a device that combines the functions
of wireless Access Point and the IP sharing router.
