Why Wireless WAN?
A wireless WAN offers many advantages for those industries that can benefit from mobile connectivity. Typical usage includes: utility services, such as meter readers; mobile sales, such as realtors; government services, such as police; and many others. For those who use a tradition PC environment, the WAN connects the user to email and data retrieval. In the thin-client environment, the WAN serves as the conduit for instructions up, and graphics updates down. While performance at lower bandwidths may appear to be significant, when comparing mobile thin client computing to traditional computing, the difference is minimized with sufficiently high bandwidth. For example, the overall performance of a thin client using Ricochet to send graphic updates is comparable to a PC transferring data and generating the user interface locally. In fact, in some cases a thin client backed up by a fast server with optimized storage can result in user access times much shorter than those of a traditional
