DNA has unveiled an upgrade to its backbone network which will allow it to support 5G services once they are ready to deploy.
The work, which has already begun, forms
part of DNA's preparations for the 5G era, but will also
immediately benefit mobile and fixed network customers, even
before 5G networks arrive, the Finnish mobile operator
Critical equipment for the backbone
network has already been upgraded and DNA’s
backbone network speeds have been raised by multiples of 400
Gbit/s to a maximum of 1.2 Tbit/s. In addition, the minimum
speeds of local area networks, i.e. regional networks, have
been raised to meet new and future requirements.
"Because data usage continues to grow
rapidly throughout Finland, minimum speeds have been increased
and capacity raised everywhere. Use of mobile data is
increasing fastest, and backbone network capacity is another
key factor in the smooth provision of mobile data. We will
continue to increase speeds and capacity, as part of normal
network maintenance and servicing," comments Mikko Kannisto,
Director of DNA's Transmission Networks.
The upgrade plans will also see network
architecture and signalling upgraded in order to enhance the
programmability of the entire network, including both the
national backbone network and its area networks, while making
interoperability more seamless.
A total of 20.85GB of data was transmitted
per user through the mobile network in the first quarter of
2018, compared to 14.97GB per user in 2017, according to
"Significantly more synergy gains can be
generated through better programmability. This will enable us
to produce and maintain multiple services on the basis of the
same work. Customer service will improve, as services become
more versatile and speeds grow," said Kannisto.
