Glossary
ARP
Address Resolution Protocol, a network layer protocol used to convert an
IP address into a physical (DLC) address, such as an Ethernet address. A
host wishing to obtain a physical address broadcasts an ARP request onto
the TCP/IP network. The host on the network that has the IP address in
the request replies with its physical hardware address.
CINR
Carrier to Interference and Noise Ratio, a measure of quality for wireless
signals.
CPE
Customer Premises Equipment, communications equipment that resides
on the customer's premises and is owned or leased by the customer.
Gateway
A node on a network that serves as an entrance to another network.
IEEE
Institute of Electrical and Electronics Engineers (pronounced I-triple-E),
an organization that develops standards for the computer, networking,
and electronics industries.
MAC Address Media Access Control address, a hardware address that uniquely
identifies each node of a network.
PKM
Privacy key management, a protocol used to authenticate nodes on the
network, and distribute and maintain private keys used for traffic
encryption.
PoE
Power over Ethernet, a solution where electrical current is run to
networking hardware over an Ethernet Category 5 or higher data cable.
No additional AC power cord is needed, minimizing the amount of cables
needed and the hassle of installing extra outlets.
RSA
Rivest, Shamir, and Adelman, a public-key encryption technology that
requires an extraordinary amount of computer processing power and
time to break. The RSA algorithm has become the de facto standard for
industrial-strength encryption, especially for data sent over the Internet.
RSSI
Received Signal Strength Indicator, a circuit or signal that indicates the
strength of an incoming signal into a receiver, such as your TR-WMX-3.5.
SNR
Signal-to-Noise Ratio, the ratio of the amplitude of a desired analog or
digital data signal to the amplitude of noise in a transmission channel at
a specific point in time.
