Market analysts and prognosticators joined in the frenzy, seemingly unable to separate future dreams from first article hardware. As such, market expectations were set high, and high they stayed, as one product after another fell short and slammed into the reality wall. In fact, the ring of these claims still echoed in the ears of customers as they tried to use products that were expensive, bulky, fragile, unsupported, incompatible, uncooperative and unstable.

Not only is this technology capable of supporting larger diameter networks, but they also tend to have lower bandwidths and higher latency effects than do the in-building networks. This tends to present a unique set of problems in application development. Significant body of research on network and system adaptation through infrastructure awareness components has been or is being conducted. This research is described in Chapter 7. However, the transformation of this research into commercially available “mobility middleware” is yet to occur.

The second digital system accepted by CTIA is CDMA, which stands for Code Division Multiple Access, and which allows users to share the entire radio spectrum through different, uniquely assigned codes for transmission and reception. In the next subsections, we briefly describe the TDMA and CDMA cellular systems. 1 Time-Division Multiple Access (TDMA) TDMA is a digital transmission technology that allows a number of users to access a single radio frequency channel without interference, by allocating unique time slots to each user within each channel.
