Augmented with Comparative Charts, photos, and diagrams, this Handbook describes, in meaningful terms, the currently available radio-based terminals and enterprise owned and operated Radio LANs employed to achieve exceptional -- almost sensational -- improvements in individual productivity, in material resource management, and in customer service levels.
Two important trends have materialized since the last edition. Radio LANs are being decoupled from the RF terminals of the same suppliers. This trend ultimately will enable one Radio LAN to service diverse types of data devices from many and varied suppliers. Lack of upper layer standards remains the only major impediment to such Radio LAN interoperability.
The second trend is a retreat from the Target Protocol Dependent Radio LAN architectural approach that became popular in 1995. While the retreat is and will continue to be slow, the return to Controller Protocol Dependent architecture is essential for satisfying the capacity and response time performance requirements of Radio LANs used for transaction processing. So important is this trend for the long range benefit of integrated enterprise automation that WCCN has broken its "no-editorials in the Handbooks" rule. In this edition, we have included an editorial in strong support of this return to sound radio network architecture.
Additionally, this Handbook provides a rare, non-engineering-comprehensible description of how Frequency Hopping and Direct Sequence Spread Spectrum work.
