Other types of resonator, dielectric resonators and surface acoustic wave (SAW) devices, are used to control higher frequency oscillators, up into the microwave range.
The effects of acceleration and vibration tend to dominate the other noise sources; surface acoustic wave devices tend to be more sensitive than bulk acoustic wave (BAW) ones, and the stress-compensated cuts are even less sensitive.
Then the solution of the acoustic wave equation is : Boundary conditions are needed at this stage to determine and the other undetermined constants.
These cuts operate at bulk acoustic wave (BAW); for higher frequencies, surface acoustic wave (SAW) devices are employed.
This assumption leads to the linear or small signal acoustic wave equation.
In the case of indoors, some devices are available, including the UWB (Ultra-Wide Band), Wi-Fi and acoustic wave devices but the beacon is suitable in many cases because of its affordability at a few thousands of yen per beacon.
