1. A method of powering a wireless autonomous device, comprising:

  • providing said wireless autonomous device, said wireless autonomous device having energy harvesting circuitry, on-board electronic circuitry, and RF transmitter circuitry;

    generating an RF transmitting profile, said RF transmitting profile including a plurality of pulses each having RF energy of a first RF frequency range, wherein each of said pulses is provided during a respective on period of said RF transmitting profile and wherein each adjacent pair of said pulses is separated by a respective off period of said RF transmitting profile, each said off period not including any RF energy;

    transmitting said RF transmitting profile to said wireless autonomous device;

    receiving said RF transmitting profile in said energy harvesting circuitry, said energy harvesting circuitry generating DC energy from the pulses included in said RF transmitting profile; and

    using said DC energy to power said on-board electronic circuitry and said RF transmitter circuitry to enable said RF transmitter circuitry to transmit an RF information signal to a receiver device, said RF information signal having a second RF frequency range different than said first RF frequency range.
