Nokia Bell Labs shows how operators can re-use
existing fiber-to-the-home (FTTH) massive-
scale deployments to satisfy the strict latency
constraints and capacity needs for mobile
transport in 4G and future 5G networks
Breakthrough means operators can prepare for
the ever-increasing amounts of data traffic
needed for 5G and the Internet of Things (IoT) in
a cost-effective way
Espoo, Finland - Nokia has announced a significant
industry breakthrough in the effort to better support
mobile fronthaul and latency sensitive services. In a
world-first, Nokia Bell Labs showed it is now
possible to use a commercial next generation PON
(NG-PON) to transport ultra-low latency CPRI
streams via a standard single fiber running between
the Baseband Unit (BBU) and the Remote Radio
Head (RRH). The proof-of concept demonstration
was done in accordance with the latency budget
requirements for the fronthaul of commercial radio
equipment, showing that existing fiber networks can
be used to cost-efficiently transport mobile traffic
and help accelerate 5G.
Fronthaul is an essential element of the C-RAN
(Centralized Radio Access Network) architecture in
mobile networks, where the processing power is
centralized and moved away from the cell sites.
This can help operators reduce the cost and power
consumption of their on-site installations along
with ease cell cooperation schemes that help
enhance mobile network capacity and coverage. In a
C-RAN architecture, the legacy Common Public
Radio Interfaces (CPRI) and some of the next
generation fronthaul interfaces require ultra-low
latency transport - often in the sub-millisecond
range - to meet the strict timing and
synchronization requirements of 4G and 5G
technologies.
Nokia Bell Labs validated that the use of next
generation PON technology XGS-PON (X=10,
G=Gigabit, S-PON=symmetrical Passive Optical
Network) technology would satisfy these strict
timing constraints and deliver the capacity needed
while reducing the cost of mobile cell site
transport. XGS-PON runs on existing fiber access
networks and allows operators to use GPON
platforms and technology to deliver high capacity
services. This is important for operators who
increasingly need to support anyhaul applications.
No longer requiring a separate network, operators
can now use existing passive optical networks used
in Fiber-to-the-home or Building (FTTH/FTTB)
deployments to quickly and cost-effectively gain the
performance and coverage they require to handle the
mobile transport of their densifying cell sites.
Peter Vetter, head of Access Research at Nokia Bell
Labs, said: "This is an important milestone in the
industry and in the advancement of 5G, showing for
the first time how a PON network can effectively be
used to support very high capacity, low latency
applications. It demonstrates the flexibility of PON
to support traditional CPRI and evolving mobile
specifications, such as fronthaul over simpler native
Ethernets, and validates the readiness of PON for the
5G era."
Federico Guillén, president of Nokia's Fixed
Networks business group, said: "I've often said that
the world is going wireless but wireless is going
fixed. This Bell Labs demonstration is another
example, successfully showing how fixed access
technologies can be used to support mobile
deployments. Mobile environments that may have
traditionally relied on dedicated transport networks
to connect cell sites to their core networks can now
use existing fiber access networks as an alternative.
The massive scale, capacity and coverage of fiber
access networks make them a perfect match to
support 5G"
In addition to mobile transport applications, passive
optical networks are also becoming an attractive
option for operators looking to support latency
sensitive services and IoT applications such as
manufacturing control and connected vehicles.
This technology breakthrough helps ensure mobile
service providers on the path to 5G are well
prepared and further expands Nokia's Anyhaul
mobile transport solutions while strengthening its
portfolio of converged access networks for fixed and
mobile services.
