Ahh, Auckland's underground toy trainset. Yet another pointless
money-pit to continually waste tax / rate-payer money on. :-\
City Rail Link to Have Full 5G Coverage From All Three Mobile Operators
-----------------------------------------------------------------------
Aucklanders will be able to stay connected on their mobile phones and
other devices when they use the City Rail Link (CRL), the country's
first underground railway, next year.
a
City Rail Link Ltd, its main contractor, Link Alliance, aand
telecommunications companies One NZ, Spark and 2degrees have begun
installing the infrastructure that will bring both 4G and 5G high-speed
mobile connectivity throughout the 3.45-kilometre-long CRL tunnels and
at the new Te Waihorotiu, Karanga-a-Hape, and Maungawhau Stations.
a
"Installing technology that allows high-speed communications
connectivity is an important part of delivering a world class railway
for Aucklanders. Not only will passengers get to new places faster, but
they will also be able to stay in touch, stream, and access information
while underground" says City Rail Link Ltd's Chief Executive Patrick
Brockie.
a
One NZ is leading the installation of the physical infrastructure on
behalf of all three network providers, supported by their technology
partner Nokia. It is the first time the three mobile operators have
collaborated to build a solution of this scale, ensuring continuous
mobile coverage in the tunnels across their networks.
a
Besides keeping passengers connected, 5G also plays a vital safety role
for the City Rail Link - helping protect people in the event of an
underground incident.
a
"Connectivity underground is crucial for real-time train tracking,
emergency communications, and integration of CRL with Auckland
Transport systems that keep public transport running," says Auckland
Transport Chief Executive Dean Kimpton. "It will help to keep trains
and passengers on time and online."
a
One NZ and CRL Ltd say installing underground mobile infrastructure is
a complex technical task, requiring careful coordination with the wider
fit outs of the CRL station and tunnel systems.
a
"We're proud to be leading the design and implementation of the mobile
network infrastructure for Auckland's underground transport network,
helping to deliver a better-connected Aotearoa. Testing is complete,
and our teams are now busy underground installing the system that will
support modern urban transport and help Kiwis stay connected throughout
their journeys," says Thaigan Govender, One NZ General Manager Mobile
Access Network.
a
Although cell coverage above ground is widespread thanks to cell towers,
establishing it underground poses significant challenges. Solid
materials such as concrete, steel, and earth used to build the CRL make
it harder to provide consistent wireless connections.
a
The work involves the installation of a large amount of sophisticated
hardware and software - over 350 radio transmitters connected by
74 kilometres of cabling, and 30 kilometres of leaky feeders (cables
that transmit radio frequencies) - to ensure mobile coverage throughout
the CRL tunnels and stations. Installation will continue into early next
year and full coverage is expected when CRL opens in 2026.
