Technical-Economic Evaluation of Spectrum Regimes: Static, Dynamic and Utopian Allocations for B3G CDMA with Coexisting UWB Devices

The technical-economic performances of static (traditional) and auction-driven dynamic radio-spectrum allocation (FSA and DSA), and of an Utopian "federated" network (with all spectrum and customers) are compared. Spectrum licensees operate cellular CDMA networks populated by heterogeneous data-downloading terminals, which may coexist with ultra-wide-band (UWB) devices. A terminal has its own data rate, channel state, and "willingness to pay". The key performance figure is the economic value of total bits transferred. The Utopian regime always performs best, but is often nearly matched by DSA. The DSA "gain" over FSA ranges from a few percentage points to as high as (in idealised cases) 200%. The technical-economic impact of "high power" UWB under all regimes is considered.
