10
next-gen tech trends
you should
know about
Heard about how Graphene could change
electronics forever, or how
modern Bluetooth devices will be able to
directly access the internet?
Here's your glimpse into the future of
technology
Do
you know your C-RAN from your SON, your WiGig from your Bluetooth
Low
Energy and your MirrorLink from your machine learning? If you don't,
then
dive in and educate yourself concerning the tech trends that get little
attention,
but are already having a big impact.
1
DEVICE-TO-DEVICE COMMUNICATIONS (D2D)
Smartphones
are about to become nodes in the network.Often called D2D or
`proximity
services', device-to-device communications is self-explanatory and
completely
revolutionary. In a way it's odd that the walkie talkie was replaced by
cell
phones that can't communicate directly with one another. D2D is designed
to
take the strain from cellular networks by kicking in when technically
possible
send
an email, a photo or a video to your pal nearby and that data will go via
Bluetooth Low Energy (a tech we'll cover later on) or Wi-Fi Direct, and not
via a cellular tower.
2
MACHINE LEARNING
It's
pattern recognition, it's statistical learning, it's predicting the future,
it's
artificial
intelligence, and it's hot stuff in modern computer science. Although
it
gets complicated, a simple definition of machine learning is when computers
take
the initiative with no input from humans. Well not much the algorithms that
inform
the computer's choices must first be dreamed up by data scientists since
computers
have no generalised analytical ability whatsoever. Machine learning is
used
by Siri and Cortana, by email spam filters and search engines.Its next home?
The
smart car, with machine learning tools for the layman after that.
3 C-RAN
Often
called Centralised RAN or Cloud-RAN, this technology is the cloud and the
cellular
network getting married.The Cloud Radio Access Network (C-RAN) the
next
big thing after LTE is a new architecture that streamlines cellular
networks.
An
easy way for mobile operators to grow both capacity and the speed of wireless
networks
is by making each cell in a cell phone network virtual. The cell towers
and
infrastructure may remain, but by using C-RAN some components are
centralised
in the cloud, and shared between cells. C-RAN depends on wired links
for
faster data transfer. It supports 2G, 3G and 4G, and can integrate with
future
cellular
and wireless standards, too.
4
BLUETOOTH 4.2
Bluetooth
Low Energy is changing the Internet of Things.This latest version of the
shortwavelength
UHF radio wave protocol that has been part of our digital lives
since
the dawn of this century is set to make the IoT a practical reality.
The
biggest recent change is that IoT devices can now talk to each other over
Bluetooth
without using a phone or computer as a conduit. The latest 4.2
specification,
debuting on devices now, is pushing the IoT to new heights.
The
first change is that beacons can only talk to a phone if the user has given
permission,
the data capacity has increased 10-fold, the data transfer speed has
risen
by as much as 250 per cent, and devices can also get on the web directly
over
IPv6.
5
LTE-ADVANCED
Mobile
broadband knows no bounds. The high-speed data standard for smartphones
is LTE-Advanced, otherwise known as 4G+ or
LTE+, and it's all about increasing
speeds.
LTE-Advanced services have already been launched in 45 countries, with
most
supporting Category 6 devices that can handle above 150 Mbps and up to
300
Mbps.
Several
operators are trialling LTE-Advanced technology capable of supporting
up
to 450 Mbps. 4K video streaming, here we come. Most new and upcoming
handsets
from the likes of Apple, Samsung, LG, Huawei and Sony can handle
LTEAdvanced.
6
WIGIG
High-speed
wireless data transfer is what WiGig promises, which may not sound
very
exciting until you realise the speeds involved. WiGig also known as 802.11
ad
can push files, photos and music ten times faster than regular Wi-Fi, and
can
ramp
up as fast as 7 Gbps.
Forget
about changing your router; WiGig is all tied up with the D2D movement
we've
already mentioned. It is perfectly suited to a future where all smartphone
users
are filming in Full HD video, and soon in 4K.Instead of clogging up the
internet,
WiGig will be the fastest way to transfer such files between devices.
WeGig
is increasingly being used in conjunction with 5G cellular networks, too.
Expect
a seamless experience when transferring a big file; you send it as normal
from
your phone to another, which intelligently swaps from cellular to WiGig to
complete
the transfer.
7
BATTERIES IN PORTABLE DEVICES
Batteries
are delaying the revolution. Almost everything we use these days is
powered
by a rechargeable lithium-ion battery, but every time you recharge your
phone
before you go to sleep at night is a reminder of the complete lack of
progress
being
made by chemists in the back rooms of consumer electronics companies.
So
numerous are the devices that need rechargeable batteries that any future
solution
needs to be very cheap, but there are breakthroughs on the horizon.
Graphene-coated
silicon has been mooted as a way of doubling the charge of a
battery,
while others have been working on aluminium-ion batteries and even on
using
sand.
8
GRAPHENE
It's
super-thin, super strong and super-flexible, and it conducts electricity
better
than
copper, and heat better than anything. It's been called the miracle material
of
the
twenty-first century, but graphene really could be about to shake electronics
to
the
core. Mass production and the `band-gap problem' remain, but now that
graphene
can be printed in ink form, there's a growing expectation that it will,
one
day, utterly change computing. Expect broadband internet that's a hundred
times
faster, flexible phones, powerful RFID tags and wireless sensors,
super-efficient
high-speed computing that makes Moore's Law look like laziness,
and
a rash of new wearables. It's all one (or maybe two) technical breakthroughs
away.
9
SELF-ORGANISING NETWORK (SON)
Cellular
networks are in an automation boom. One of the biggest wireless trends
of
all is the self-organising network (SON), which essentially takes the human out
of the day-today tasks of running an ever more complex network.
There
are various flavours of architecture, and they've all primarily been created
to
help run 4G networks, the greater bandwidth of which means ever increasing
complexity
and performance needs. However, at its core SON is about saving
costs
for network operators by eliminating the need for manual configuration of
equipment.
10
IN-VEHICLE SMART PHONE STANDARDS
So
far, the connected car as a coherent concept has been a mess, with most car
manufacturers
keen to push their own platforms for apps and integration with
devices.However,
the smartphone-car interface is beginning to coalesce around
three
operating systems that let smartphones and tablets talk to in-car
infotainment
systems:
Android Auto, Apple CarPlay and Broadcom's MirrorLink.
With
most upcoming connected cars compatible with one or all of these systems,
expect
industry chat to become more about processing speeds, the use of capacitive
touchscreens,
and the functionality of apps rather than which platform is supported.
