Quortus The company Headquartered near London, UK Software technology company Sub-system oriented Core network functionality at the network edge Technology branded EdgeCentrix, or ECX Radio agnostic Target markets: Enterprise, public-safety, tactical Channels: System integrators, solution providers Small Cell Forum award winner 2012 Best service or application for small cells www.quortus.com3 4. Small Cells in the Enterprise Enterprise voice traffic predicted to grow at 12% to 2017 Needs: Increased integration with IT and local voice systems Scalable, high quality voice and data capacity Challenges: Enhanced quality coverage for voice Mobile hand-off Demarcation between MNO and Enterprise Opportunities New MNO business models such as neutral host & cloud services Improved relationships with Enterprises reduced churn www.quortus.com4 5. New Enterprise solutions Solutions based around Small Cells Cost effective Relative ease of installation Localised intelligence Distributed processing, not unlike small cells themselves Option for hosting New cloud oriented hosting Enabler for future new revenues & services Time to market Leverages value within existing eco-systems www.quortus.com5 6. Small Cell Forum Release 2 Comprehensive guide to Enterprise deployment Set of 25 documents, including a reference architecture Helps unlock Enterprise opportunity Follows-on from successful Residential Release New challenges, increased complexity, more stakeholders Published December 2013www.quortus.com6 7. SCF Reference Architecture More functionality outside traditional MNO core Careful and considered migration towards network edge Two new main architectural functions Enterprise Small Cell Concentrator (ESCC) Enterprise Small Cell Gateway (ESCG) Voice is main Enterprise driver Still the Killer App Data isnt natural! SCF067 Enterprise Small Cell Network Architectures Document available from www.scf.iowww.quortus.com7 8. Enterprise characteristics Residential Single cell (single location) Low user density Low traffic load No mobility Limited local services User expectation same as macro Limited scope to monetise Examples: Home, SOHOwww.quortus.comEnterprise Multi-cell (multi-location?) Medium user density Medium traffic load Mobility, local and out to macro High level of local service interop Higher level of user expectation Potential sources of new revenue Examples: SMEs, corporate buildings Shopping malls 8 9. The migration to the edge Traditional network core: Defined by size and weight as much as functionality Scaled by making big box in the middle even bigger Compare with Internet-style distributed model: Scaled by addition of intelligent endpoints Relatively minor changes to the core (ie to capacity) Need to recognised balance of core/cloud vs edge Powerful drivers for neutral host SP layer www.quortus.com9 10. On-the-edge benefits Offload allows capacity scaling Aggregation allows coverage scaling Service convergence were services used/consumed Allows better leverage of non-cellular ecosystems Drives innovation, and communities not just a phone number Disruption kept at edge, (rapid) innovation at edge More (perceived?!) end-user control monetise-able www.quortus.com10 11.
