NEC sharpens the beams with Blue Danube RF Coherency Technology

When Steve Perlman first introduced pCell technology to the world, using interference to deliver a precise cell of coverage to every connected device...

The problem is, it's not true. As Martin Cooper reveals in his new memoir Cutting the Cord: The Creator of the Cell Phone Speaks Out, cellular technology was actually being developed in the late '50s and through the '60s. By the time Star Trek debuted in 1966, Cooper and his team at Motorola were practically in the home stretch; in 1973, they debuted the first-ever handheld mobile telephone, the brick-like DynaTAC. Cooper himself made the first cell phone call on October 17, 1973--to his chief competitor at AT&T, with whom he'd been in a bit of a cellular space race, as revealed in the book.

Best Readings in Full Duplex Wireless Communications While conventional half-duplex wireless systems rely on transmitting and receiving in non-overlapping time slots or frequency channels, full duplex (FD) communications and the underlying self-interference cancellation (SIC) techniques may improve the attainable spectral efficiency while reducing latency. This is made possible by recent advances in antenna design and signal processing techniques specifically in multiple input multiple output systems, which make SIC of 80-110 dB possible. In fact, SIC has been demonstrated in applications...
