1. To run an existing networkbased application locally (within the walls) using wireless network cards and notebook PCs, no modification to the existing software application is needed. The wireless card is simply a method for untethered access. The actual application is still loaded on the workstation PC, but the data is accessed on the server via the wireless network card.

2. It is also possible to run an existing network-based application locally using wireless network cards and a Microsoft terminal server. A terminal server client on the remote device accesses the terminal server to start a Windows-emulation session. This runs the application that accesses the data . The actual application is not loaded on the workstation PC. This is known as a "thin client" application, because most of the work is done on the back-end server, and very little work is performed on the local PC. This fast and efficient method can use older, slower computer workstations. This is also the perferred approach to using a Pocket PC with limited memory. It allows all application screens to be presented, just as if they were running locally on the Pocket PC.

3. The Terminal Server client also runs through Internet Explorer as a plug-in. Remote users with access to the Terminal Server client or Internet Web browser can access their company's applications remotely over the Internet.

4. Remote users may also have a wireless access to the Internet, using the CDMA or GPRS network protocols. CDMA stands for Code Division Multiple Access, the most common but slower method of connecting wireless devices. GPRS stands for General Packet Radio Service, which is a very high speed "cellular" service for wireless communicationds. Remote access with wireless network cards designed to communicate with the GPRS or CDMA can be accomplished with any wireless device. The remote device uses the Terminal Server client to access the applications quickly and efficiently.
