Level-Setting: PAWR Approach
Attribute Approach
Problem Definition Enhanced efforts of ~400 university researchers who need mid-scale
testing capabilities to ensure success
Early Industry Involvement Multi-use research platforms with “pre-competitive” research topic
areas selected bottom-up by university PIs, with industry input
Research Scope Mid-sized areas within cities, experimental platforms, 10-20 antenna
sites, backhaul, SDRs
Flexibility and Speed 1 - 2 platforms per year in years 1,2 and 3
Streamlined governance,
deployment, and operation
One governance consortium focused on upfront research and policy;
city/university teams propose how to streamline deployment and ops

millimeter-wave bands that are about 28GHz, 60GHz with a
target of 100 Gbps in data rates for small-cell networks that
cover a few city blocks.
Network Slicing to focus on the providing differential
isolated Micro services to multiple users from RAN to
Network slicing .

implementations to orchestrate end-to-end VM,container,
VNF deployment in a cloud native environment including
radio resources that operate on the wireless edge.
Microservices Architecture assembling, controlling, and
composing services. We provide a service control plane that
is layered on top of a diverse collection of back-end service
implementations, including VM-hosted VNFs, container-
based micro-services, and SDN-based control programs that
embed functionality in white-box switches
Massive MIMO 2.5-2.7GHz and 3.5-3.7GHz 128

PHY/MAC/network FDD, full duplex research to
design, build and demonstrate high bandwidth
connectivity to multiple users simulataneously.
RAN CU-DU Split to advance capabilities of
baseband-RRH and other functional splits being
debated n different communities e.g.eCPRI, OTN
backhaul, O-RAN.
Applications/Services in later years – Platforms
will serve as examples of Smart and Connected
Community networks that demonstrate potential
applications/services including Cyber-Physical
Systems, Cyber-Security, Internet of Things,
Robotics, Smart and Connected Health, and Big

What Next ?
Round III RFP – Rural Broadband Focus
• Rural Focus: This third-round RFP seeks to focus on
applying advanced wireless technologies to transform the
deployment and operations of fast, low-latency, and
reliable broadband networks in rural and other low-
density geographic areas in an efficient and affordable
way
• Innovative Technology: Proposers should create a
testbed for experimenting with advanced wireless
technologies and network architectures – combined with
existing technologies – that may transform the existing
rural broadband deployment cost curve through
innovations in technologies and engineering processes
