In every commercially deployed radio technology, from cellular phones to WiFi (802.11b) to WiFi5
(802.11a), the methods employed to create the signal transport, called the modulation technique,
are widespread early on. They can vary from mono-phase to bi-phase to multi-phase
approaches. The marketplace drives these disparate approaches to a standard over time, and,
typically, the most efficient methods (measured as a combination of factors such as power
consumption, cost to build, data rate, transmission distance, and bit error rate) are the ones
chosen in the end. This white paper discusses mono-phase and bi-phase Ultra-Wideband (UWB).
