Spectral Efficiency News Today

Are you tired of waiting for the next download or waiting for your mobile signal to die down and dropping calls? The answer is LTE Advanced, which enables you to watch high-definition videos on your phone without buffering. We'll go into greater depth in this article about LTE Advanced, which has the potential to transform

It has been years in the making, but 5G has finally become a reality. Coverage has been expanding rapidly in the U.S. Here's everything you need to know.

Nokia has announced the results of a trial conducted last year over a 3,551 km subsea cable between Jurong in Singapore to Manado in Indonesia – and they are pretty impressive.

Meet Martin Cooper, the inventor of the cellphone, a pioneer of wireless communications, and a critic of smartphone addiction.

The 2.5-pound, 10-inch-long model’s inspiration came from a bespoke, two-way radio system that Motorola created in the 1960s for Chicago police.

NextNav said it will use Nestwaves capabilities to combine signals from existing terrestrial LTE/5G networks with its own TerraPoiNT location system. #pressrelease

The problem is, its 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 comp...

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 outp...
