SMARTRange™ is a wireless transceiver architecture based on a new type of radio demodulator. This novel, patent-protected architecture drastically improves receiver efficiency, thereby doubling the range over previous designs, while maintaining ultra-low power consumption.
How do receivers work?
Receiver sensitivity is affected by two factors, the noise generated in the receiver circuits, and the amount of noise that can be tolerated when recovering data from the received signal in a circuit known as a demodulator. Reducing the generated noise in the receiver and/or improving the noise tolerance of the demodulator, will improve receiver sensitivity and range.
Existing receivers use one of two demodulation schemes, coherent or non-coherent. Coherent schemes trade excellent noise tolerance at the expense of high power consumption, while non-coherent schemestrade poor noise tolerance in return for low power consumption. Both coherent and non-coherent schemes therefore demonstrate significant disadvantages, due to fundamental limits of the receiver demodulation scheme.
SMARTRange™ uses a new type of mathematical transform, never previously applied in radio demodulators, to deliver excellent noise tolerance and low power consumption. SMARTRange™ therefore dramatically improves the efficiency over previous designs. The power that SMARTRange™ products save in the demodulator allows us to put more power into the receiver circuits, thus lowering noise generated and delivering a receiver with much improved receive sensitivity and range.
