Key Terminology
802.1x
An IEEE standard for port-based Network Access Control; it is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN port, either establishing a point-to-point connection or preventing access from that port if authentication fails.
AES (Advanced Encryption Standard)
An encryption algorithm for securing sensitive but unclassified material by U.S. Government agencies and, as a likely consequence, may eventually become the de facto encryption standard for commercial transactions in the private sector.
ARPU
Average revenue per user
Authentication
The process of determining whether someone or something is, in fact, who or what it is declared to be. In private and public computer networks (including the Internet), authentication is commonly done through the use of logon passwords.
Backbone
A large transmission line that carries data gathered from smaller lines that interconnect with it.
Channel
A transmission path.
DOS (Disk Operating System)
The first widely-installed operating system for personal computers.
DAS
Distributed Antenna System; series of mini antennas placed throughout the building to provide wireless coverage
dBm
Decibel referred to 1 milliwatt
Donor Antenna
A directional, rooftop antenna that transmits and receives RF signals from a desired cell site or tower; from the “macro” network
EAP (Extensible Authentication Protocol)
The original 802.11 standard.
Encryption Keys
A piece of information (a parameter) that determines the functional output of a cryptographic algorithm. In encryption, a key specifies the particular transformation of plaintext into cipher text, or vice versa during decryption.
Lightweight Access Point
The Lightweight Access Point is an 802.11 a/b/g dual-band, zero- touch configuration and management access point that delivers secure, cost effective wireless access with advanced WLAN services for enterprise deployments. This lightweight access point provides industry-leading RF capabilities with a wide breadth of deployment options to maximize wireless LAN performance, security, reliability, and scalability.
Mesh
A mesh network is a local area network (LAN) that employs one of two connection arrangements, full mesh topology or partial mesh topology. In the full mesh topology, each node (workstation or other device) is connected directly to each of the others. In the partial mesh topology, some nodes are connected to all the others, but some of the nodes are connected only to those other nodes with which they exchange the most data.
Microcell, BTS
A “mini” cell site or base station that resides in the building and connects to the carrier’s network via T-1. Does not pull off the macro network; provides dedicated capacity for the DAS
POE(Power over Ethernet)
This technology describes a system to transfer electrical power, along with data, to remote devices over standard twisted-pair cable in an Ethernet network.
Rogue Access Point
A wireless access point that has either been installed on a secure company network without explicit authorization from a local network administrator, or has been created to allow a hacker to conduct a man-in-the-middle attack.
Repeater, Amplifier, Bi-directional Amplifier (BDA)
A device that amplifies and filters RF signals
RF
Radio Frequency; wireless signal
Roaming
A general term in wireless telecommunications that refers to the extending of connectivity service in a location that is different from the home location where the service was registered.
TKIP (Temporal Key Integrity Protocol)
Part of a draft standard from the IEEE 802.11i working group and is an enhancement to WEP (Wired Equivalent Privacy) security.
Unified Communications (UC)
UC bridges the gap between telephony, conferencing, email, voice mail, instant messaging, video, and collaboration across a variety of user interfaces and devices.
VOIP
Voice over Internet Protocol is simply the transmission of voice traffic over IP-based networks.
VoWLAN
Voice over WLAN is a method of sending voice information in digital form over a wireless broadband network.
VPN (Virtual Private Network)
A computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires.
WiFi Alliance
A global, non-profit industry association of more than 300 member companies devoted to promoting the growth of wireless Local Area Networks (WLANs).
Wireless Convergence
Enterprises are beginning to deploy both voice and data services to provide seamless integration between in-building and wide-area services. The goal is to enable a single wireless device to interact seamlessly over multiple wireless networks.
WEP (Wired Equivalent Privacy)
The encryption algorithm built into the 802.11 (Wi-Fi) standard.
WPA
Wi-Fi Protected Access (WPA and WPA2) is a certification program administered by the Wi-Fi Alliance to indicate compliance with the security protocol created by the Wi-Fi Alliance to secure wireless computer networks.
WiMAX
A wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks
Wireless Mesh
A communication network made up of radio nodes organized in a mesh network created through the connection of wireless access points installed at each network user's location.
WLAN Controller
Wireless LAN Controllers are responsible for system wide wireless LAN functions, such as security policies, intrusion prevention, RF management, quality of service (QOS), and mobility. They work in conjunction with Access Points and the Wireless Control System (WCS) to support business-critical wireless applications.
