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
