Nokia next generation fiber technology delivers high capacity, low latency mobile transport solution for 5G era

- Nokia's mobile transport solution extends the performance of
fiber access networks to converge business, residential and mobile
services on a single infrastructure
- Leveraging fixed networks enables operators to reduce CAPEX of
mobile backhaul by as much as 50%
Espoo - Nokia is introducing a broad set of
next-generation fiber access solutions that deliver on the capacity
and latency requirements essential for mobile transport. Nokia's
addition of next-generation 10Gbps passive optical network (PON)
and point-to-point (P2P) fiber to its mobile transport solution
gives operators the capacity, scale and flexibility needed to
support network densification in the 5G era.
Nokia's mobile transport solution enables operators to leverage
existing passive optical networks used in Fiber-to-the-home (FTTH)
deployments and quickly gain the capacity and coverage 5G requires.
Eliminating the need to create parallel and dedicated networks,
operators can now cost-effectively connect radio cells to a fixed
network at scale and gradually introduce more bandwidth as service
needs increase. With some forecasting the number of small cells to
grow at 38% CAGR through 20211, this flexibility will be critical
as networks continuously evolve to better address ultra-broadband
demands.
Nokia's mobile transport solution includes a number of new
enhancements to its 7360 ISAM FX access node and 7368 ISAM ONT
optical network termination devices, delivering the multi-gigabit
capacity needed to support the massive throughput requirements and
cell densification 5G requires. Nokia's ISAM portfolio combines
carrier-grade transport capabilities with best-in-class
synchronization support required in 3G, 4G and 5G mobile transport
networks, providing operators such as Du and Telefonica with access
to the flexibility needed to effectively ready their networks for
5G.
The enhanced mobile transport solution is also being used as
part of a Bell Labs proof-of-concept that demonstrates the
flexibility of 10G symmetrical PON networks for low latency
applications such as mobile fronthaul. By adding gateway
functionality to a next-generation PON network, Nokia is able to
convert mobile fronthaul CPRI signals to Ethernet. The proof of
concept validates the readiness of PON for fronthaul and its
Ethernet-based evolutions for the 5G era.
Federico Guillen, president of Nokia Fixed Networks said:
"The biggest opportunity on the horizon for fixed networks is the
arrival of 5G. It's clear that 5G will require very high capacity
and low delay, but what is less certain is just how much capacity
will be required for backhaul and what latency will be sufficient.
We take the guesswork out of the equation. Our solution allows
operators to access existing PON networks that have virtually
unlimited capacity to meet their needs today, with the added
flexibility to add 10G PON evolutions gradually as demand for more
bandwidth and services increases. The massive throughput and cell
densification strategy of 5G make it a perfect match for existing
FTTH deployments."
Rupert Wood, Research Director at Analysys Mason said:
"Fiber networks and next-generation access technologies such as XGS
and TWDM-PON are uniquely positioned to address the evolving mobile
transport needs in the era of 5G. By leveraging FTTH networks that
are already in place, and vendor technologies such as Nokia's
mobile transport solution, mobile operators can quickly gain
access to the capacity, scale and flexibility needed to support
'anyhaul' applications."
Did you know:
- In urban areas, 5G radio deployments will use cm Wave & mm
Wave spectrum with 150 to 300 radio sites per km².
- Comparable urban FTTH networks are 10x denser, can support up
to 3,000 connections per km² and have by design the headroom to
connect these additional radio sites.
