A New Class of Spin-Wave-Based Devices May Improve Overcrowded Electromagnetic Spectrum

Author: Nina Welding

Grocery stores. Coffee shops. Even some cities offer public WiFi. Add to those access points the number of private WiFi networks that exist and it’s easy to understand why the allocation and usage of the electromagnetic spectrum — the number of “channels” available for wireless communication — is stretched to its limits. The impending demand of machine-to-machine (M2M) and Internet-of-Things (IoT) devices will put even more of a strain on spectrum usage. Possible solutions to this problem, such as dynamic spectrum access and cognitive radios, have been proposed but their success is based upon a more efficient use of the spectrum.
