Wireless Communications Interoperability Future Trends and Directions Environmental Factors • Radio congestion will increase • Spectrum will continue to be limited • Infrastructure development will remain costly • Federal funds will be limited Industry Factors • Competition is limited • Engineers listen to other engineers more than end users—they add functionality because they can • Designers often misunderstand or don’t inquire enough about user needs • Commercial products set expectations Future Ideas • Fed govt and state/local govt should partner with commercial companies to provide primary data coverage; back up for voice • State and local govts need more experienced engineers working for public safety—accurately assess needs; communicate better with designers and vendors (or require independent expert/university partner to help them) • All levels of govt should mandate more training for end users—learn functionality; certification testing, e.g., state POSTs • Fed govt should clear the 700 band and reserve for PS Future Ideas (cont) • Local reqmts must force a holistic approach to design—consider human engineering factors in addition to technical and field operations • Fed govt should sponsor research into developing a modular approach to radio design—start with a “mainframe box” and add desirable features • Software defined radios—future solution; we can’t wait for it • Fed govt directs the development of open standards; states apply—will improve competitiveness Future Ideas (cont) • RFPs should include life cycle replacement; Fed govt should help by encouraging this in grants
