  1. Point to Multi-Point microwave backhaul in Next Generation mobile backhaul networksTNMO London May 2010

  2. The Company • Headquarters in Cambridge UK • Market-driven, world class technology • Research and product design in Cambridge • Manufacture by Benchmark • Largest carrier-class PMP vendor, four-fold increase in sales 2007 to 2009 • More than 50 customers in 35 countries • First Backhaul vendor sponsor to join NGMN Alliance

  3. Agenda • Evaluating last-mile backhaul alternatives for European Operators • What are the cost implications • PMP Backhaul • Considerations for next generation networks • Conclusions

  4. The backhaul crunch Next Generation Mobile Broadband networks also need to make money

  5. The wall of mobile data • Smartphones and Dongles are just the beginning • Machine-to-machine communications will change dynamics of mobile Source: Nokia

  6. Key Factors in Backhaul Deployment • Must be enough for Backhaul Requirements of today and tomorrow – with an established capacity roadmap • Drive down ever increasing antenna lease and spectrum costs along with radio equipment site costs • System Capacity • System Operational Cost • System Capital Cost • Speed to Deploy • Equipment needs to provide services in a few hour, not weeks or months – with minimal planning and licensing • Equipment plus Installation must meet market targets

  7. Evaluating last mile backhaul for European Operators What are the options?

  8. Last Mile Backhaul Options Western European Operators – Grading Of Principle Backhaul Options Grading 1-5 where 1 is very poor and 5 is excellent Source: Informa Telecoms & Media

  9. Cost comparison: various backhaul technologies Source: Informa Telecoms & Media • Forecast cost to transport data traffic: as traffic increases, the need to build or upgrade backhaul increases • Voice traffic is assumed to be carried on E1 • Cost increases towards the end of the forecast period due to volume of traffic • Deployed Fibre is second most expensive but is a long term option for some operators • Microwave technologies are the most cost efficient

  10. A balanced backhaul solution PMP has the lowest microwave OPEX PMP has the lowest CAPEX Informa Telecoms and Media: “Last Mile Backhaul Options for West European Mobile Operators”

  11. Evaluating last mile backhaul for European Operators What are the cost implications?

  12. Mobile operators want backhaul solutions that cost less, deliver higher performance and reduce the complexity of their networks

  13. Cost comparison: Tier-1 UK Operator • Cost comparison (Europe) between PMP and the other two prominent technologies, PTP and hybrid fibre (leasing) • Although both leasing fibre and hybrid backhaul technologies are considered cost-efficient, analysis shows that PMP can provide better cost savings in backhaul, even compared to the widely established PTP microwave in Western Europe. • The analysis presented has been undertaken for an international Tier-1 operator running a mobile broadband network in the UK. Calculations are for a 5-year period. • Cost savings of PMP compared with TDM/fibre leasing for the total cost to transfer traffic amounts to US$497 million per year during 2010, increasing to US$2.8 billion per year for 2014 • PMP is expected to offer cost savings of US$26 million during 2010 and this will increase to US$248 million during 2014 compared to PTP microwave.

  14. PMP Microwave Backhaul Is there a another way?

  15. PMP Microwave Architecture Point-to-point Point-to-MultiPoint Single Hop = predictable latency Access point PtP uses 1 frequency, 2 radios and requires 2 installations per link PMP uses 1 frequency per sector. To backhaul 9 cell sites, VectaStar uses 8 fewer radios:10 vs. 18

  16. GE GE GE GE GE GE GE Outdoor Indoor GE GE GE Backhaul on Demand Step 2: Zero footprint sector Step 1: Single PtP link Step 3: Multi-sector Gigabit Ethernet Hub Site a PMP Ethernet Hub where there is a need to provide or upgrade backhaul coverage Add sectors as demand increases Hub economics enable variable sector sizes/capacities Radio Controller available to aggregate multiple sectors and provide hybrid support New sites require one radio – deployment time halved PMPsystem architectureenables a paradigm shiftin microwave backhaul network design

  17. 30Mbps 30Mbps 30Mbps 30Mbps Stat-MuxandAggregation Point-to-Point backhaul planners have to provision for peaks, i.e. 30Mb/s per NodeB: Trafficmeasurements from 4 HSPA Node Bs in a VectaStar network sector Total provisioning: 4 x 30Mbps =120 Mbps PTP: Bandwidth not used is wasted! 150 Mbps Sector th’put VectaStar aggregates cellsite traffic in sector Built-in optimisation and statistical multiplexing reduces peak backhaul requirement to40 Mbps 120 Mbps Vectastar: Unused bandwidth is available for other cellsites in the sector 40Mbps 40Mbps

  18. LTE PMP Backhaul solution for London: 145 Cell sites 8 Hub sites 150Mb/s Peak 30Mb/s Mean Utilises overlapping sectors to increase capacity in dense, high traffic areas Comparison showed that at 100Mbps, PtP exhausts available spectrum. VectaStarused less than half the spectrum needed for PtP Case Study: LTE Network London

  19. VectaStar CAPEX advantage compared to Implemented PtP from 2 links: Point to Point is 40% moreexpensive at 5 links Point to Point is 80% moreexpensive at 15 links • VectaStar Cost to Deploy Compared to Point-to-Point • CAPEX London LTE network business case Broader London Case Study of Savings over 5 year Business Case - With 360 BTS and 13 Hubs – Net Present Value: Point to Point is 44% more expensive in CAPEX (First Year) Point to Point is 38% more expensive in OPEX (All Years) VectaStar used Half the Spectrum of the PtP solution Deploy PMP Access Point Network for Lower Capex than PtP - AND save on OPEX
