6 Technology Screening Overview The technology screening used key metrics to identify the most promising candidates from each technology family –The key metrics for terrestrial technologies that were selected and used are data rate and communications range –For the satellite and over-the-horizon family of technologies, the screening criteria was a gate (ability to use protected spectrum) and the technology data rate –Each technology family was assessed and plotted on a tri color chart, with acceptable, marginal and good regions inferred from COCR requirements –Most promising technologies from each family were selected for detailed evaluation (depending on family performance, 0, 1 or many were selected) Next two slides provide screening results in a graphical format. The third slide provides a summary of the technology screening results.
