In the 50-100 GHz frequency range, the permanent use of lower-order modulation is ideal - the large spectrum allocations and "pencil beam" antenna beamwidths make the use of narrow RF channels unnecessary. By utilizing lower-order modulation, transmit amplifiers can be run near their maximum power ratings and radios are able to accept much weaker RF receive signal levels. These factors keep link costs down without sacrificing link performance. Since these links normally use low-order modulation, this limits the use of adaptive modulation as a tool to significantly improve link budgets. BridgeWave's AdaptRate technology overcomes this limitation, providing temporary increases in link budget (when needed) by reducing over-the-air signal bandwidth, rather than by changing modulation order. Reducing the air signal bandwidth by a factor of ten reduces the amount of background noise that the received RF signal must exceed by a factor of ten (or 10 dB). This 10 dB noise reduction provides 10 dB of additional rain fade link budget, an amount sufficient to materially improve link availability in the presence of strong rain fades.
