RAN/Backhaul Key Elements
� SDN-enabled networking� Centralization for resource management and optimization
� Access side and EPC side virtualization
� Orchestration to create LTE ad hoc network
� NFV � Dramatic reduction in the number and cost of elements
� NFV of key functions to effectively orchestrate RAN
� Open and standardized approach� Interoperable with service provider’s existing network components
� Does not put additional capacity requirement on SP network
� Auto SON� Self-configuring, self-optimizing, self-healing RAN – real time
� CWS eNodeBs (LTE and Wi-Fi)� Integrated access and backhaul
� Flexible backhaul (LOS and NLOS)

SDN Mesh = Integrated Edge Router
“SDN-driven backhaul could save carriers up to $9 billion
by 2017” (Strategy Analytics)
� CWS: access+ backhaul in the same form factor:
� 2X GigE, 2X built-in mesh radios, LTE macro
backhaul, custom
� Full-featured third generation mesh technology� Mesh is pure “multi-point” to “multi-point” link, i.e. there is no server
node, client node, etc.
� Multi-homed – any egress (wired or LTE) on a given node is available
to full mesh cluster. E.g. 10 meshed cluster of CWS has 3 Ethernet
backhaul that terminates on 3 of the 10 CWS, this backhaul is shared
among all 10 nodes.
� CWS can provide Ethernet backhaul to external devices as well e.g.
external Access Points, traffic camera etc.6

Transport Options
� Multiple Secure Transport Options
� Wired broadband
� LTE based backhaul
� Wireless mesh (NLOS, licensed and unlicensed spectrum),
with broadband
� Backhaul mesh interconnect with broadband
� Self-optimization and self-healing
� Loads re-balancing via SON capabilities
� Coverage Adjustment based on traffic and network needs
� Packet re-routing in case of a link failure

Example - Rural Deployment –
What do we bring ?
� Simple quick Installation –
� 6 hours to install and commission one CWS
� 3 days to light up a rural community with cluster of 4 CWS
� Planning “Lite”
� Eliminates the backhaul Challenge
� Use what is available when it becomes available & aggregate all sources
� In Band 4G Backhaul
� Mesh Backhaul
� Fiber / DSL / ADSL
� Low cost of Operation
� 80W power consumption
� Standard domestic Supply

Rural HetNet Architecture

� CWS connect together via wireless mesh to form a CWS cluster
� Mesh is pure “multi-point” to “multi-point” link, i.e. there is no server node, client node, etc.
� Multi-homed – any egress (wired or LTE) on a given node is available to full mesh cluster
� The Cluster aggregates all backhauls available
� Each CWS supports two independent wireless mesh � can operate on multiple frequency and transmit /receive packets independent of each
other
� Each CWS is self-configured and self-managed via the LTE Access Controller
� Each CWS has an integrated GPS receiver location reporting and time sync

How Solution Addresses Rural Coverage
Challenges
Challenges Parallel Solution
Cost: Need to spend as much on
low density rural network
infrastructure as for high density
urban areas
Reduced Cost:
eNodeBs are built from low cost commodity components
LAC runs on COTS hardware
Time and skill level to deploy Less time and lower skill level to deploy
Instant on auto SON for instant/plug-n-play deployment
On-going maintenance Hands free with SON � local community can manage itself
Backhaul � LAC enables mesh backhaul on CWS nodes, only a few require fixed backhaul
connections
� Two independent wireless mesh: can operate on multiple frequency and
transmit /receive packets independent of each other
� Nodes can daisy chain to each other to extend coverage
Power � Low power consumption
� Can run up to 24 hrs on car battery as a power back up.
Spike in Usage/traffic mitigation Optimize spike in usage due to season; special circumstances, time of day, etc.
SON on LAC auto optimizes resource usage
X2 brokering mitigation, ICIC, CoMP for great customer experience
Resilience: potential equipment
damage or vandalism in remote
locations
Monitor any potential equipment damage or vandalism in remote locations

Mesh links
(n/NLOS)
� SDN mesh backhaul links can be configured for mesh deployment multi-point to
multi-point scenarios or long haul point to point links
� Only few CWSs need wired backhaul or LTE backhaul from macro
