What is Tomcat ?
Tomcat is a reference implementation of the Java servlet
and JavaServer Pages (JSP) specifications. It is
intended as a platform for developing and testing
What is UDDI ?
Universal Description, Discovery, and Integration (UDDI)
is an XML-based standard for describing, publishing, and
finding Web services. UDDI is a specification for a
distributed registry of Web services.
What is UMTS
Developed by Nortel Networks, Universal Mobile
Telecommunications Service (UMTS) is a standard that
will provide cellular users a consistent set of
technologies no matter where they are located worldwide.
UMTS utilizes W-CDMA technology.
What is VLR
The Visitor Location Register (VLR) is a database that
contains temporary information about subscribers.
What is WAE
The Wireless Application Environment (WAE) provides a
application framework for small devices. WAE leverages
other technologies such as WAP, WTP, and WSP.
What is WAP
Wireless Application Protocol (WAP) is a protocol for
transmitting data between servers and clients (usually
small wireless devices like mobile phones). WAP is
analogous to HTTP in the World Wide Web. Many mobile
phones include WAP browser software to allow users
access to Internet WAP sites.
What is WAP Gateway
A WAP Gateway acts as a bridge allowing WAP devices to
communicate with other networks (namely the Internet).
What is W-CDMA
Wideband Code-Division Multiple Access (W-CDMA), also
known as IMT-2000, is a 3rd generation wireless
technology. Supports speeds up to 384Kbps on a wide-area
network, or 2Mbps locally.
What is WDP
Wireless Datagram Protocol (WDP) works as the transport
layer of WAP. WDP processes datagrams from upper layers
to formats required by different physical datapaths,
bearers, that may be for example GSM SMS or CDMA Packet
Data. WDP is adapted to the bearers available in the
device so upper layers don't need to care about the
What is WMA
The Wireless Messaging API (WMA) is a set of classes for
sending and receiving Short Message Service messages.
See also SMS.
What is WML
The Wireless Markup Language (WML) is a simple language
used to create applications for small wireless devices
like mobile phones. WML is analogous to HTML in the
World Wide Web.
What is WMLScript
language designed as part of the WAP standard to provide
a convenient mechanism to access mobile phone's
What is WSP
Wireless Session Protocol (WSP) implements session
services of WAP. Sessions can be connection-oriented and
connectionless and they may be suspended and resumed at
What is WTLS
Wireless Transport Layer Security protocal (WTLS) does
all cryptography oriented features of WAP. WTLS handles
encryption/decryption, user authentication and data
integrity. WTLS is based on the fixed network Transport
Layer Security protocal (TLS), formerly known as Secure
Sockets Layer (SSL).
What is WTP
Wireless Transaction Protocol (WTP) is WAP's transaction
protocol that works between the session protocol WSP and
security protocol WTLS. WTP chops data packets into
lower level datagrams and concatenates received
datagrams into useful data. WTP also keeps track of
received and sent packets and does re-transmissions and
acknowledgment sending when needed.
