  Parallel wireless digital communication with ultralow power consumption is
critical for emerging edge technologies such as 5G and Internet of Things.
However, the physical separation between digital computing units and analogue
transmission units in traditional wireless technology leads to high power
consumption. Here we report a parallel in-memory wireless computing scheme. The
approach combines in-memory computing with wireless communication using
memristive crossbar arrays. We show that the system can be used for the radio
transmission of a binary stream of 480 bits with a bit error rate of 0. The
in-memory wireless computing uses two orders of magnitude less power than
conventional technology (based on digital-to-analogue and analogue-to-digital
converters). We also show that the approach can be applied to acoustic and
optical wireless communications
