The idea here is that IDT's switches will offload tasks that take up a lot of bandwidth from the digital signal processors, thus improving bandwidth performance by up to 20%.

People expect four to five bars signal and enough bandwidth to stream video at all times.

It's also providing copper cable networks for the "last mile" of installed wire from central switches to homes and businesses, and products that help increase bandwidth, maintain signal integrity and optimize wavelength.

The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency.

And, because the digital signal occupies only 65% of the excess allotted bandwidth, stations can use the leftover spectrum to transmit text information like the artist's name, song title or more advertising.

This provides a means of switching a signal between two wavelengths a neat trick for using bandwidth more effectively.

Bandwidth - which in the UK will come when the analogue signal is switched off - needs to be freed up by regulators and manufacturers have to provide phones that can cope with TV viewing alongside the myriad other functions already eating up battery life.
