1xRT
1xRT is short for a single carrier radio transmission technology. A 3G wireless technology is based on the CDMA platform. 1xRT does have the capability of providing ISDN-like speeds of 144Kbps.
802.11
The IEEE standard for wireless communications accepted in 1977 and since then has been enhanced:
802.11 - Applies to wireless LANs with 1 to 2 Mbps in the 2.4GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).
802.11a - An extension to 802.11 that provides up to 54 Mbps in the 5GHz band using orthogonal frequency division multiplexing (OFDM) encoding scheme rather than FHSS or DSSS.
802.11b - An extension to 802.11 generally referred to as WI-FI with transmission speeds to 11Mbps that includes a fallback to 5.5Mbps, 2Mbps, and 1Mbps in the 2.4GHz band range. It was ratified in 1999 allowing wireless speeds to Ethernet standard of 10Mbps. This is the most compatible industry standard today but could be replaced by the newer standards such as 802.11g or other ones to come.
802.11g - An extension to 802.11 that provides 20+ Mbps in the 2.4GHz band range.

CDMA
Code Division Multiple Access is Qualcomm's digital wireless technology. Each call is distinguished by a unique code resulting in a higher use capacity. Sprint PCS and Verizon Wireless use this technology in their wireless networks.
CDPD
Cellular Digital Packet Data is a wireless transmission method that uses the analog cellular networks (AMPS). It allows information to be transmitted on on idle voice channels and transmissions are sent in packets. The data rate on CDPD is 19.2 kpbs.
HTTP
Hypertext Transport Protocol is the set of rules for exchanging text, graphics, sound, video, etc. on the world-wide web. Web servers like Apache are simply HTTP servers that service requests from an Internet browser like Internet Explorer, Netscape, Mosaic, etc. The port used for HTTP is 80.
Java
Java is an object-oriented programing language from Sun and can be used to develop applications on the web. A major feature of Java is portability across networks and with any device using a Java Virtual Machine.
Java Beans
Java Beans is an interface that lets you build re-usable components that can be deployed in a network. These Java Beans can be combined with other components on the same computer or distributed across the network to form an application.
JDBC
Java Database Connectivity is an Application Program Interface (API) for connecting programs within Java to the data in popular databases.
JMS
Java Message Service is an API that supports messaging between computers on a network. JMS provides a common interface to standard messaging protocols used to exchange data between computers rather than users.
JNDI
Java Naming and Directory Interface enables Java based applications to access multiple naming and directory services such as LDAP, CORBA, etc.
JSP
Java Server Pages is a servlet-based technology for controlling the content or appearance of web pages. Servlets run on the web server and JSP is comparable to Microsoft's ASP.
LDAP
Lightweight Directory Access Protocol is a software protocol for enabling anyone to locate organizations, individuals, and other resources on the Internet or Corporate Intranet. Developed by Microsoft being very similar to Novell's NDS.
RSA Key Encryption
RSA is an Internet encryption and authentication system that uses an algorithm developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. The RSA algorithm is the most commonly used encryption and authentication algorithm and is included as part of the web browser from Microsoft and Netscape.
SSL
Secure Socket Layer is the industry standard for protecting web pages. This protocol provides data encryption and server authentication, message integrity, and client authentication. SSL is built into major browsers such as IE and Netscape in two strengths: 40-bit and 128-bit with most secure websites using 128-bit encryption. When you connect to an HTTPS web server, you are using SSL.
VPN
Virtual Private Network is a private data network that makes use of the public telecommunications infrastructure, maintaining privacy through the use of tunneling protocols such as L2TP. VPN can promote better utilization of router/switch hardware and assist LAN Management.
WAP
WAP is the Wireless Access Protocol for use in cellular telephones, pagers, handheld devices, and wireless computer equipment. WAP provides a complete environment for wireless applications that includes a wireless counterpart of TCP/IP. WAP also uses WMLScript, a compact JavaScript like language that runs in limited memory. WAP supports input methods such as keyboard, voice recognition, finger pad, etc. WAP is device independent.
WEP/WEP2
Wireless Equivalent Privacy and WEP 2 simply provides basic network security for wireless networking equipment. WEP in combination with 802.1x and a Radius Server running Kereberos 5 can significantly increase security, however, additional devices can be procured to make the wireless network even more secure.
WI-FI
Wireless Fidelity standard of 802.11b with speeds up to 11Mbps in a 2.4GHz band range.
WI-FI5
Wireless Fidelity 5 is the standard of 802.11a with speeds up to 54 Mbps in the 5GHz band range.
WML
Wireless Markup Language, formerly called HDML (Handheld Devices Markup Language) is a language that allows the text portion of web pages to be presented on cellular telephones and PDAs via wireless access. WML is part of WAP.
