Term Definition
Access Point (AP) A device that provides network access to associated stations (connected wireless
devices). A wireless router can function as an AP.
ACK Acknowledgment. This is a response to a transmission to indicate that the data
packet was received correctly.
ARP Address Resolution Protocol. This is a broadcast protocol for mapping IP
addresses to MAC addresses.
CHAP Challenge-Handshake Authentication Protocol. This is a protocol for
authenticating users to an ISP.
CPE Customer-Premises Equipment. This is also known as a station.
dB Decibels. This is a measure of intensity.
dBm Decibel-milliwatts. This is a measure of power relative to 1 mW. This is commonly
used to measure wireless signal power. A higher power leads to better signal
quality.
DDNS Dynamic DNS. This is a system for updating domain names in real time. It allows a
domain name to be assigned to a device with a dynamic IP address.
DHCP Dynamic Host Configuration Protocol. This is a protocol for allocating IP addresses
dynamically so that addresses can be reused when hosts (e.g. computers) no
longer need them.
DNS Domain Name System. This is a distributed and hierarchical naming system
for computers, services, or any resource connected to the Internet or a private
network.
EIRP Equivalent Isotropically Radiated Power. Each country sets the legally permitted
maximum for the EIRP limits on each channel.
ESSID Extended Service Set Identifier. This is the name of the wireless network. It is case-
sensitive and up to 32 alphanumeric characters in length. The ESSID differentiates
one wireless network from another. All access points and devices trying to
connect to a specific wireless network should use the same ESSID (and password)
to enable effective roaming.
FTP File Transfer Protocol. This is a protocol for transferring files between network
nodes.
HTTP Hypertext Transfer Protocol. This is a protocol used by web browsers and web
servers to transfer files.
IP Internet Protocol. This is the primary communications protocol used for relaying
network packets (also known as datagrams) across an internetwork using the
Internet Protocol Suite. IP is responsible for routing packets across network
boundaries. It is the principle protocol that establishes the Internet.
ISP Internet Service Provider.
L2TP Layer 2 Tunneling Protocol. This is a tunneling protocol used to support virtual
private networks (VPNs) or as part of the delivery of services by ISPs. It does not
provide any encryption or confidentiality by itself. Rather, it relies on an encryption
protocol that it passes within the tunnel to provide privacy.
LAN Local Area Network.
