While India finds
its way around 4G, in some parts of the world the conversation has moved
up a notch to 5G. And this was clear at the Intel Developer Forum in
San Francisco, where the chipmaker tried to paint a picture of what the
5G world might look like. As it turned out, it wasn’t just about a
faster Internet.
What is 5G?
For the consumer it will mean ultra high data speeds (upwards of
20GBPs), ultra low latency, and new devices and form factors. But behind
all this will be mobile edge computing with serious processing power
being added to base stations.
Intelligent networks
The network will have no option but to transform. If 4G is driven by
video, 5G will be driven by the Internet of Things. And that means the
network will have to be intelligent enough to understand how to allocate
its resources, a capability it does not have at the moment. It will
need to figure out that it is the self-driving car that needs a
fraction-of-a-millisecond response every time — and maybe not the
toaster. So, it will have to be content-aware, user-aware and
location-aware.
Not really neutral
Any lack of context would mean wastage of precious bandwidth, as the
service runs the chance of allocating more bandwidth where it isn’t
required. It can also not afford to be neutral when it comes to data, as
that could again lead to wastage. The neutrality will have to be
limited within “swimlanes”, but not all use cases. Regulatory frameworks
will also need to evolve to keep pace with this change.
Internet from the sky
Base stations might move to drones or balloons to ensure that the
Internet of Everything is also the Internet of Everywhere. This new
revolution will take access to connectivity and, through it, access to
knowledge to vast sections of the population, and entire geographies
that have been cut off so far. The drones might initially act like the
post service, downloading content to a location at a regular predestined
interval, and uploading all the pending data there. Internet in these
cases might not really be real time.
Connected world
Everything from the farm that produces food to the refrigerators that
store it will be connected. Even by conservative estimates, we are
looking at some 50 billion connected devices by the end of 2020. To put
that in perspective, there are over 15 billion connected devices in the
world at the moment, according to rough estimates. And this 50 billion
will not include the billions of sensors that will be reporting on
everything from body temperatures to water levels in rivers.
But when?
Of course, all this isn’t happening in a hurry. With countries like
India struggling even with 4G, the 5G world is at least a few years away
for most countries. However, it will be easier to achieve for countries
like South Korea and Japan who have mature 4G networks and ecosystems.
Also, the 5G environment cannot be created by any one company or group
of companies. It will need concerted efforts by almost all tech
companies, service providers and governments. One of the first
challenges will be in setting up a universal standard to ensure that
everything is communicating in the same language.
