Can turning off analogue TV make broadband better?

Insatiable demand for wireless services means that, despite new
technology, the airwaves are running out of room. Could making use of
the space between signals be the solution to all our problems?, a BBC
News report asks.

By 2014, global data traffic will increase by 39 times from current
levels, reaching 3.6 exabytes (around 3.9 billion gigabytes) per
month, according to wireless firm Cisco.

And this means that current wireless networks are approaching breaking point.

Every device that uses wireless technology - from remote-locking car
keys and TV controls right through to the latest smart phones or
tablets - uses a part of the spectrum.

While it is hoped that 4G and LTE technology will relieve some
pressure on capacity, many see this as only a short-term solution.

"People are becoming more used to being connected, having elements of
their homes or workplaces linked up to something - everything from
your laptop to your wireless network," says Richard Traherne, of
product development firm Cambridge Communications.

"The fact we're consuming more data means there is more pressure on
this finite resource of radio spectrum."
