HyPHY Flex Reference Design Provides Carrier-Grade OTN Fronthaul
for C-RAN
PMC-Sierra, Inc. (PMC®) (NASDAQ:PMCS), the semiconductor and
software solutions innovator transforming networks that connect,
move and store big data, today announced an OTN-based solution for
fronthaul networking in Centralized Baseband RAN (C-RAN)
architectures used for LTE and LTE-Advanced systems. Until now,
C-RAN deployments have been stalled by complex fronthaul latency
and timing requirements. PMC’s solution meets the required latency
and beats jitter specifications with up to 75 percent margin,
enabling OTN to be used to implement carrier-grade fronthaul (see
infographic and video). Customers using PMC’s widely deployed HyPHY
OTN processors can upgrade their existing designs to rapidly bring
OTN-based fronthaul equipment to market.
To accommodate unprecedented mobile traffic growth, leading
operators worldwide, such as China Mobile, SKT, NTT and Orange, are
evolving their Radio Access Networks from distributed to a
centralized base station model to maximize return on CAPEX and OPEX
while improving spectral efficiency. A centralized RAN architecture
lowers CAPEX through reduced site engineering expenses and improved
baseband utilization. OPEX is reduced through lower power
consumption, site leasing and maintenance expenses. However,
centralizing baseband processing requires a high-capacity,
high-reliability fronthaul network capable of transporting Common
Public Radio Interface (CPRI) up to 20km from cell site to baseband
processing resources.
OTN is the standard protocol for transporting multi-service data
over DWDM networks. With PMC’s breakthrough solution, OTN is now
proven to provide sufficiently low latency and jitter to meet 3GPP
specifications for end-to-end latency and jitter while multiplexing
multiple CPRI signals onto a single 10G wavelength, substantially
reducing fiber consumption and reducing expensive optic modules
(see whitepaper).
“Solving the mobile fronthaul networking challenge is the key to
enabling C-RAN,” said Dr. Chih-Lin I, chief scientist of wireless
technologies, China Mobile Research Institute, CMCC. “CMCC is
looking for more cost-effective, scalable and carrier-grade
fronthaul solutions. As the standard protocol for carrier-grade
transport, OTN is a very compelling option and we’re excited to see
ecosystem partners like PMC innovating to deliver solutions that
address the networking needs of mobile fronthaul.”
“Distributed remote radios in a C-RAN architecture has
tremendous potential to address expanding mobile capacity and
coverage needs, but it creates a fronthaul networking problem that
PMC has now solved,” said Babak Samimi, vice president of marketing
for PMC’s Communications Business Unit. “PMC’s new OTN-based mobile
fronthaul solution not only meets operator needs, it also allows
carriers to build on their end-to-end OTN strategy and benefit from
the operational efficiency and management simplicity that comes
with a converged network.”
Based on PMC’s field-proven HyPHY 20Gflex and HyPHY 10Gflex
devices, the reference design provides the OTN management and
protection functionality required for large-scale RAN deployments.
PMC’s innovative new embedded software measures and reports uplink
and downlink latency, equalizing it to within nanoseconds. The
solution supports up to 16 CPRI links on a single wavelength to
maximize fiber resources.
Availability
PMC’s fronthaul reference design will be available in March
2015. The reference design includes software and firmware updates
to the existing HyPHY SDK and firmware binary files, FPGA sample
code, as well as application notes. With this reference design,
existing HyPHY 20G/10Gflex designs can be easily upgraded for CPRI
fronthaul support. For more information, visit
