Amplitute modulation
Modulation is the process of putting information onto a high frequency carrier wave for transmission. The key reasons for modulation are:
- To allow for frequency division multiplexing and support multiple transmissions via a single channel.
- For practicality, as transmitting very low frequencies would require antennas with miles in wavelength.
There are different types of modulation including analogue modulation (AM, FM, PM), pulse modulation, and digital modulation. Amplitude modulation (AM) varies the amplitude of the carrier wave and produces sidebands at sums and differences of the carrier and modulating frequencies. Double sideband suppressed carrier (DSB-SC) modulation suppresses the carrier wave to improve power efficiency but requires a complex receiver for demodulation.
Passive and active devices
Microwave devices can be passive or active. Passive devices include terminations to absorb microwave power without reflection, as well as directional couplers and phase shifters. Terminations include matched loads made of lossy materials placed in waveguides to absorb all incident power. Directional couplers are four-port devices that couple power between two connected waveguides in one direction only. Phase shifters provide a variable phase shift without changing the physical path length using materials like ferrites or dielectrics.

A Wr@p transceiver establishes a narrow-band powerline communication exploiting the “last meter”, i.e. the power supply cord between the appliance and the outlet, where a proxy device, the smart adapter (SA), flexibly deals with standard home networking solutions. At the appliance side, such an approach allows for (i) connectivity at negligible cost and, (ii) keeps hardware and software virtually independent from the actual home networking protocol (since different configurations of the smart adapter take care of it). In this work, after recalling the basics of Wr@p point-to-point communication, an extension to the multipoint-to-point scenario is introduced. Design of silicon implementations integrated into commercial microcontroller architectures are presented and the results of extensive test of fabricated devices under actual operating conditions are detailed. Moreover, we present a complete Wr@p development solution, featuring wireless networks integration.
