- snooper
- Someone who casually and usually inadvertently interfaces with a wireless network.
- spread spectrum
- The spreading of the carrier signal over a wider part of the frequency spectrum. Direct sequence and frequency hopping are two types of spread spectrum.
- TCP (Transmission Control Protocol)
- A protocol that establishes and maintains connections between computer devices attached to a network. TCP is used in conjunction with IP, which is commonly referred to as TCP/IP.
- TDMA (time division multiple access)
- A process that allows only one user to transmit in any given time slot. Each user has use of the entire bandwidth during its assigned time slot.
- terminal emulation
- A mechanism for users to interface over a network to applications running on a centralized computer. VT-220, 3270, and 5250 are types of terminal emulation.
- transceiver
- A device that both transmits and receives information. The transceiver resides in a radio NIC.
- VPN (virtual private network)
- The use of special software on the client device that controls access to remote applications and secures the connection from end-to-end using encryption.
- WEP (Wired Equivalent Privacy)
- A part of the 802.11 standard that defines encryption between devices connected to a wireless local area network.
- Wi-Fi
- A brand name given to wireless LANs that comply with standards as defined and published by the Wi-Fi Alliance. Wi-Fi standards are based on the 802.11 standard.
- Wi-Fi Protected Access (WPA)
- A security protocol defined by the Wi-Fi Alliance that enables computer devices to periodically obtain a new encryption key. WPA version 1 implements TKIP and WEP; whereas, WPA version 2 implements the full 802.11i standard (which includes AES).
- wireless LAN
- A network that satisfies wireless networking needs within the area of a building or college campus. 802.11 and Wi-Fi are popular standards defining wireless LANs.
- wireless MAN
- A network that satisfies wireless networking needs within the area of a city. Wireless MANs make use of 802.16 and proprietary standards.
- wireless PAN
- A network that satisfies wireless networking needs within a small room or reach of a person. Bluetooth and 802.15 are popular technologies for wireless PANs.
- wireless WAN
- A network that satisfies wireless networking needs over a large geographical area, such as a country or the entire world. Satellites offer a means for extending radio signals over a wireless WAN.
- WISP (wireless Internet service provider)
- A company that offers wireless connection services to the Internet for homes and offices. WISP often provide wireless access in public wireless LAN hotspots.
