Traffic jams in the future could cause potentially dangerous data
snarl-ups as cars packed with entertainment, safety and navigation
features vie for airwaves with smartphones, tablets and networked
features in other vehicles, according to a study.
By 2024, mobile
networks will see machine-to-machine (M2M) connections jump 10-fold to
2.3 billion from 250 million in 2014. Half these links will be
automotive, said the study published on Thursday by Machina Research.
On the roads, about one in five vehicles worldwide will have some
form of wireless network connection by 2020, or more than a quarter of a
billion connected vehicles, according to a forecast from technology
research firm Gartner.
Connected cars with onboard WiFi
connections could cause spikes in cellular data demand when traffic
grinds to a halt as drivers seek alternative routes and bored passengers
search for entertainment on phones and tablets, the Machina study says.
says car navigation and collision detection systems that rely on local
networks to identify obstacles could then become strained, if they are
not carefully designed and regulated.
The report says the dangers
will mount over the next decade but stops short of painting a picture of
bloody roadside pile-ups. Such scenarios can be averted if network
operators pay more attention to managing surging, unpredictable data
demands in congested areas and device makers do more to ensure their
products do not interfere with other network users.
terms of overall data volumes, connected cars don't present much of a
problem," said Matt Hatton, founder and chief executive of Machina, a
British market research firm specialising in machine-to-machine data
"But network resource management is not based on
total traffic volume. It's based on particular cell sites during peak
times of network use," Hatton said of the antennas and equipment used to
transfer mobile calls and data to and from a local area.
traffic in rush hour could double in the immediate vicinity of congested
areas due to the electronics on board connected cars, Machina
Already, most drivers stuck in traffic jams expect
mobile phone coverage to drop out from the sheer volume of callers who
suddenly find themselves bumper-to-bumper.
Less noticeably, phone
users in densely populated areas can see superfast 4G data connections
drop to slower 3G links or even 2G connections capable only of limited

cars, as with other M2M devices, don't behave like smartphones," Hatton
said, due in part to the vastly more diverse set of devices that will
come into play with so many machines talking to other machines.
