There are 7.5 billion people in the world and more than 4 billion of them don’t have access to the internet that means that over 50 percent of the world is missing out.
Global internet traffic is said to triple over the next five years the majority of this traffic is going to come from wireless devices such as your smartphone. The wireless spectrum is already in very short supply, and as the IOT (internet of things)grows, all of your household gadgets and machines will become accessible through wireless.
So how can we support the growing internet traffic?
The answer so far is by using dynamic spectrum management (DSM) it seems to be the perfect solution to the problem. “DSM enables the spectrum to be used more efficiently, it relies on a Geolocation database which contains details of assets and rules, which allow’s the spectrum to be allocated in real time based on the location of the user and some other things such as radio parameters” quote from Nominet.
TV white space or TVWS is helping to make the internet accessible to people it could never have reached before, TVWS, in short, is the name given to parts of the wireless spectrum that were made available during the digital TV switch over,there are huge benefits to using tvws radios as they can offer broadband speeds over several kilometres the signal can also travel through permanent obstacles. TVWS is free for anyone to use and build their own network.
So how does it work? Well your TVWS client station talks to a base station then the base station connects to a database over the internet and the database shows and gives a list of available channels to use connecting to one for you to use.
How and who will it benefit?
DSM will benefit anyone who lives in an area where traditional broadband cannot reach. The internet has become almost essential for modern day life and people are missing out due to their location, difficult terrain or developing countries. TVWS is a very cost efficient way of bringing the internet to them when otherwise not possible.
It’s not only beneficial to consumers but it also hugely benefits network operators by extending connectivity by up to 10km with no line of sight or need for large infrastructures used for 3G/4G/5G it also enables new business models, this means it is extremely cost effective to set up in new territories that would otherwise be impossible or expensive to reach.
So all in all dynamic spectrum management seems the right solution for the problem we are facing in our ever expanding modern world.
