Making the urban small cell happen
Early deployments underway
• Urban environment challenging • Flexible backhaul solutions required • Metnet designed to overcome issues
and enable rapid deployment
Metnet self-organising backhaul
• Multipoint-to-multipoint
• Distributed Ethernet network
• Carrier class QoS
• High 1Gbps capacity, low 150µs latency
• Robust distributed GPS synchronisation
• No RF planning or antenna alignment
• Simple installation
Challenges for wireless backhaul
• Dense urban canyons
• LOS and multipath issues
• GPS difficulties
• Limited sites available
• Sub-optimal sites
• Attachment restrictions
• Site access restrictions
• Conservation area in city centre
• Difficult for site acquisition and lamppost planning approvals
• Less restrictions on CCTV poles
• But fewer poles and shorter: 6m vs 8m
• 100-200m links, including NLOS
UK: Cambridge
Existing • Two CCTV cameras with WiFi backhaul • Public WiFi access point
Installed • CCS Metnet node • Small cell • Installed by two people in 45 minutes
Installation on CCTV poles
Flexibility to handle sub-optimal sites
• Temporary indoor installation
• No street furniture currently available
• External nodes require listed building consent
• NLOS link via building reflection
Flexibility to handle sub-optimal sites
223 NLOS link
South Africa: Cape Town
• Deployed for AfricaCom 2015
• Improve coverage and capacity at show
• 10 days to deploy, integrate and test
• Indoor and outdoor small cells
• Rooftops and indoor site for backhaul
• Included 350m NLOS link
• Live deployment since Oct 2014
• Busy commercial area
• Backhauling ZTE small cells
• Increase capacity & optimise coverage
• Difficult RF & GPS environment: Tall, reflective buildings & narrow streets
• Distributed GPS-derived synchronisation
China Mobile: Longyan
• Small unit for easier planning approvals
• Flexible technology for rapid deployment
• NLOS capability for sub-optimal sites
• SON interference-based scheduler for hostile environment
• Distributed GPS for robust synchronisation
• Carrier-class performance
Enabling small cells today
Metnet backhaul with integrated small cell
• Single, compact design
• Under 8kgs
• Simplifies and speeds up deployment
• Hosts small cell variants: LTE-A, LTE-U, MulteFire, WiFi
• First implementation with ip.access LTE small cell
The world’s first self-organising small cell microwave backhaul
