1 Deployment of a next generation public WiFi and LTE small cell network in London s Square Mile

2 Metnet self-organising backhaul Multipoint-to-multipoint, mesh Self-organising, self-optimising, self-healing Carrier class QoS High 1.2 Gbps capacity per node Very low link latency Carrier grade synchronisation GPS, 1588v2 and SyncE No RF planning or antenna alignment Simple installation Commercial in confidence 2

3 City of London small cell network In April 2017 the City of London unveiled plans to significantly improve wireless connectivity throughout the Square Mile The City had offered around 3,000 street assets for use in a public tender for use as telecommunications infrastructure based upon 4G small cells next generation Wi-Fi network neutral host backhaul system. Contract to build and manage the network was awarded to CTIL, infrastructure joint venture between Telefonica/O2 and Vodafone. Project is one of largest single investments in wireless infrastructure ever seen in London Commercial in confidence 3

4 Ecosystem Players City of London Corporation CTIL O2 iwireless JB Riney TYCO Cisco Nokia CCS Virgin Media Municipality awarding wireless concession. Infrastructure joint venture between Telefónica and Vodafone. Awarded contract to build and operate network. Telefónica UK s operating subsidiary responsible for building and managing the network, involving O2 Wireless and O2 WiFi divisions. Systems integrator responsible for network design, site acquisition and installation. City of London contractor responsible for managing street furniture. City of London contractor responsible for managing CCTV locations. Aironet 1560 WiFi access point provider. Small cell provider. Metnet self-organising microwave backhaul provider Fibre backhaul provider. Commercial in confidence 4

5 Key network components CCS 28GHz Metnet small cell backhaul solution 1.2Gbps high QOS SON mesh backhaul Cisco Aironet 1560 Wave2 Wi-Fi small cell Gbps capable Nokia FWEA V3 (1800 Flexizone) FDD LTE small cell multi-operator capable up to 120 concurrent users Virgin media 1Gbps fibre to the kerb offering Commercial in confidence 5

6 mmwave backhaul challenges Dense urban canyons Neutral host for WiFi and 4G LOS and multipath issues GPS difficulties Limited sites available Sub-optimal sites Attachment restrictions Site access restrictions Commercial in confidence 6

7 Metnet: important features for this deployment Security and traffic shaping/qnq features for multi-operator support AC power terminated in standard isolator (no need for bulky transformers clogging columns) Simplified node design (e.g. multiple antenna types or mounting kits not required) Service availability better than 99.99% Mesh resilience vital for frequent power cuts (UKPN faults, cars hitting columns, etc.) Re-parenting nodes essential for meeting launch targets Link preferences used to influence topology (link stability, avoid LOS obstructions, etc.) 100% success rate for deploying links to each planned site (target capacity met at each site) Minimal site re-visits required for optimization Zero touch configuration Commercial in confidence 7
