Glossary (V-W)

VPN- (Virtual Private Network)
Private networks that are configured within a public network. Carriers
build VPNs that appear as private national or international networks
to the customer, but physically share backbone trunks with other customers.
VPNs enjoy the security of a private network via access control and
encryption, while taking advantage of the economies of scale and built-in
management facilities of large public networks. VPNs have been built
over X.25, Switched 56, frame relay and ATM technologies. The VPN adds
an extra layer of security. A huge growth in VPN use is expected.
WAE- (Wireless Application Environment)
The part of the WAP protocol that application and service developers
use most in their work. The WAE consists of the WML and WMLScript specs
as well as the Wireless Telephony Application Interface (WTAI) that
specifies how WAP applications can access mobile phone functionality
(initiate a call, send an SMS).
WAP Alert
An exclusive Simplewire product that enables wireless devices to receive
a reroute via text-message to a url where the user can access more information
than can be provided within the character limit of a text-message.
WAP Stack
A set of protocols that covers the whole process of wireless content
delivery: From the definition of WML and WML Script for creating the
actual layout of the content to the specifications of security measures
in the WTLS, and to the lowest parts of the stack dealing with the actual
transport of content.
WAP- (Wireless Application Protocol)
An open standard for communication between handsets and the Internet.
WAP is a wireless communications environment for delivering Web data
to wireless terminals with minimal screen display. An initiative started
by Unwired Planet, Motorola, Nokia and Ericsson to develop a standard
for wireless content delivery on the next generation of mobile communicators.
WAP strips all but graphics for display on small screens, such as mobile
phones. A mini-browser is an integral part of WAP enabled phones. WAP
enabled phones first appeared in Europe at the end of 1999.
