Glossary - 10 WT4070/90 Wearable Terminal Integrator Guide
U
Visible Laser Diode (VLD). A solid state device which produces visible laser light.
W
Warm Boot. A warm boot restarts the wearable terminal by closing all running programs. All data that is not saved to flash
memory is lost.
WAP. (Wireless Application Protocol) A set of specifications, developed by the WAP Forum, that lets developers using
Wireless Markup Language build networked applications designed for handheld wireless devices. WAP was designed
to work within the constraints of these devices: a limited memory and CPU size, small, monochrome screens, low
bandwidth and erratic connections.
Wearable Terminal. In this text, wearable terminal refers to the WT4070/90 wireless portable computer. It can be set up to
run as a stand-alone device, or it can be set up to communicate with a network, using wireless radio technology.
WEP. Wired-Equivalent Privacy protocol was specified in the IEEE 802.11 standard to provide a WLAN with a minimal level
of security and privacy comparable to a typical wired LAN, using data encryption.
WPA. Wi-Fi Protected Access is a data encryption specification for 802.11 wireless networks that replaces the weaker WEP.
It improves on WEP by using dynamic keys, Extensible Authentication Protocol to secure network access, and an
encryption method called Temporal Key Integrity Protocol (TKIP) to secure data transmissions.
WPA2. Wi-Fi Protected Access 2 is an enhanced version of WPA. It uses Advanced Encryption Standard instead of TKIP.
WLAN. Wireless local-area networks use radio waves instead of a cable to connect a user device, such as a wearable
terminal, to a LAN. They provide Ethernet connections over the air and operate under the 802.11 family of specifications
developed by the IEEE.
