NEXT-GENERATION
ALL PROGRAMMABLE BACKHAUL
Integrated microwave and millimeter wave modems
with network aware high-speed packet processing
Most mobile backhaul networks have evolved into complex
combinations of legacy voice-centric networks and new data-centric
packet-switched IP networks. Stringent and varied deployments require
flexible, scalable, and high-capacity modems that can support multiple
bands, modulation rates, and LoS/non-LoS connections. Integrated
hierarchal traffic management, switching, packet processing, and OAM
functionalities have also become vital for meeting strict service-level
agreements and for efficiently rolling out new services that effectively
monetize investments in wireless infrastructure.
There has been innovation of various technologies to address capacity
and coverage challenges. Primary among these are Cloud-RAN and
small cells – both of which require hauling capabilities. It is being
increasingly viewed that wireless fronthaul and small cell backhaul can
be best served with millimeter wave links, in both point-to-point and
mesh topologies. Xilinx’s wireless backhaul solution has advanced
modems and packet processing elements specifically designed to meet
those market needs.
Xilinx All Programmable FPGAs and SoCs and proven IP put wireless
network designers a generation ahead. Our industry-leading 28nm
portfolio helps meet fast-changing our market requirements with highperformance, low-power silicon and productivity-boosting design tools.
Lower geometry nodes such as 20nm and 16nm bring significant
increase in performance and decrease in power dissipation.
Design integration is increasingly becoming a top priority for vendors.
Xilinx devices are highly integrated to enable designers to implement
more functions using fewer chips. As many as seven discreet devices
can be replaced with a single Xilinx Zynq™-7000 All Programmable
SoC and MPSoC in16nm. Xilinx FPGAs and SoCs are ideally suited
for multi-gigabit wireless modem solutions meeting the power and
performance requirements at right price points.
Next-Generation Scalable Millimeter Wave Modem
Point-to-Point Microwave
The challenge for product designers is to support a range of different products with increasing complexity and productivity
while maintaining lower costs. The platform-based approach seems to be best at addressing those requirements. At the core of
those platforms, All Programmable devices offer flexibility, migration options and scalability across different applications.
A 1024QAM modem core is a must have to meet stringent requirements for today’s wireless backhaul networks, where
reliability, timing, and cost constraints are paramount. The Xilinx solution supports legacy interfaces such as multiple E1/T1
and SDH as well as Gigabit Ethernet. Data rates are scalable up to 1Gbps in a single polarization and 2Gbps in dual-polarized
mode. Enhanced phase noise tolerance enables BOM cost reduction and optimization for end equipment and exploits the
benefits of higher-order modulations in field.
Upper millimeter wave bands are a good fit for small cell backhauling, where high capacity LoS links can be used for short-haul
data transmission. An efficient way to achieve this is by mesh or multipoint network topologies that can be implemented using
Xilinx vBand or eBand TDD modems. 10Gbps wireless fronthauling solutions can be designed leveraging the same platform.

Xilinx flexible packet processing is enabled by its innovative Software
Defined Specification for Networking (SDNet™) SmartCOREs™ with
the ability to support IP transport tunneling, Layer 2 Ethernet or Layer
3 IP/MPLS deterministically in hardware. The SDNet companion core
- Hierarchical Traffic Manager -- assures granular QoS, limits network
congestion, and enhances per user services quality. Operators could
further enhance their ARPU with new monetization services enabled by
the SDNet traffic management platform. The programmable aspect of the
SDNet tool chain and easily parameterizable traffic management functions
meet and exceed diverse mobile backhaul services requirements.
