RURALBROADBANDBLACKSPOTS
could become athing of the past after
Vodafone launched what it claims is
experimental network-sharing
technology to broaden the number of
suppliers that can offer 4G access in
less populated areas of the UK.
Collaborating with Intel, the network
giant’s system of open radio access
networks (OpenRAN) is aproject
devised to release cutting-edge
networking equipment from the
stranglehold of asmallnumber of
companies, in what is believed to be the
first of its kind in Europe.
With OpenRAN, Vodafone is hoping the
design of hardware and software in networking
infrastructure becomes standardised so that it
can be used by awider number of
providers to more easily deliver mobile
data services to rural areas.
“OpenRAN improves the network
economics enabling us to reach more
people in rural communities, and that
supports our goal to build digital
societies in which no-one is leftbehind,”
said Vodafone’s CEO Nick Read.
Trials will run in 120 rural locations
in the UK, as well as abroad in countries
including the Democratic Republic of
the Congo and Mozambique.
Vodafone’s announcement feeds intoindustry
and public sector effortstoexpandnetworking
access to countryside locations, given the staggering
infrastructure gap that exists in the UK between the
nation’s urban and rural areas.

PROTECTINGMEDICALDATAis an important part
of ensuring that sensitive information stays private.
But such data can help deliver useful insights to the
medical world to deliver better diagnosis and care.
Now Nvidia has joined forces with King’s College
London (KCL) to createartificial intelligence systems
to extract insights from medical data without
actually taking that information from its source.
The technique,known as federated learning, uses
multiple parties to train acentralised deep neural
network. Nvidia and KCLuse this method fora
central system, which contains the algorithms to
analyse medical imaging data at alocal hospital
rather than sucking up data intoacentral server.
Instead, aclient is installed on the hospital’s
systems, which processes the imaging data locally
and only sends back what it has learnt from that
information, rather than the data itself.
“The centralised server then takes multiple
realisations of the model that have been trained on
separatedatasets and creates aconsensus out of it,”
explains Jorge Cardoso,associateprofessor at KCL.
“This consensus is sent back to the hospitals,
learns from data again and the updated models are
sent back to the centralised server.”
The process is repeated until the algorithm learns
all that it can from the data, without discovering
who the data belongs to or where it came from.

help keep medical data private
c
TESLAHASUNVEILEDafeature that allows users
to remotely ‘summon’their cartotheir location.
However,the tech has already run intoproblems,
with cars crashing intoobjects and other vehicles.
Social media posts relating to the Smart
Summon feature show Teslas driving intoagarage
door,being struck by areversing vehicle and more.
The software updatetothe Tesla app was rolled
out to select users on 26th September.
“With Smart Summon,
customers who have purchased
Full Self-Driving Capability or
Enhanced Autopilot can enable
their car to navigateaparking
lot and come to them or their
destination of choice,aslong as
their car is within their line of
sight,”said the company.
“It’s the perfect feature to use if you have an
overflowing shopping cart, are dealing with afussy
child, or simply don’t want to walk to your car
through the rain.”
Smart Summon works by having aTesla owner
with acompatible car hold down abutton in the
Tesla app to summon the vehicle; releasing the
button will cause the car to stop.
But in the week after the app updatewas released,
problems started to arise.Inone
instance,anowner expected the
car to detect oncoming cars at a
junction and stop automatically,
only to be disappointed.
“I took my fingeroffwhen I
saw that it wasn’t slowing down,
but I’m not sure which kicked in
first,”saidthe owner.
