  4. Small-Cell Backhaul: Wireless Solutions The Myths & Value of Microwave MW: Area-Licensed Spectrum(26/28/32/42 GHz) Perceived as Attractive Candidate Solutions: Sub 6 GHz, PtP/PtMP  NLOS 60 GHz, PtP  High Capacity, Unlicensed Perceived as Macro-Cell Backhaul Oriented: MW Technologies, PtP/PtMP 4

  5. MW Technology for Small-Cell Backhaul Reality • Has inappropriate form factor and shape • Has high consumption, and complex installation • Can have attractive shape & compact size • Benefits from existing, field-proven H/W and S/W • Brings innovations • Antenna auto-alignment • Zero-touch provisioning • Low power consumption 300x300x285mm 265x145x166mm Perception 5

  6. MW Radio Capacity for Small-Cell Backhaul Reality • There is plenty area licensed spectrum, with an attractive licensing scheme • Two channels are sufficient, for a Small-Cell Backhaul network • Links achieve up to 540 Mbit/s Full Duplex, which is future-proof for LTE Small-Cells • PtMP configuration can efficiently offer up to 2.2 Gbit/s, at aggregation sites • Many channels, and complex techniques are required for sufficient throughput • MW spectrum is congested and expensive Perception 6

  7. Link Planning for Small-Cell Backhaul Reality • A Multipoint, multi-hop architecture extends to any location, maximizing the LOS connectivity • Pursuing LOS connectivity is best-practice as range, capacity and reliability are optimized! • Near LOS may be possible for small radio paths (i.e. link through vegetation) • RF planning procedure is very simple and known to operators (same as for macro-cell backhaul) • LOS is difficult to be achieved in reality • Requires complex RF planning Perception 7

  8. MW for Small-Cell Backhaul Reality Perception Macro-Cell Technology Insufficient Performance Myths Busted MW Evolves with Significant Innovations for Small-Cell Backhaul MW Delivers LTE-Backhaul Grade Performance MW Utilizes Simple, Proven Network Planning Procedures Complex RF Planning 8

  9. Small-Cell Backhaul: A New Service Layer New Service Layer, Greenfield Deployment, Specifically for Small-Cells 9

  10. Small-Cell Backhaul: The Microwave Solution Microwave: Area-LicensedSpectrum 26/ 28/ 32/ 42 GHz Bands Flexible Connectivity: PtPand/or PtMP Multi-hop/Relay Architecture Accelerating Backhaul & Small-Cell Deployment 10

  11. The Value of Area-Licensed MW Spectrum Plenty of Regulated, Uncongested Spectrum: 26 GHz: 1762 MHz 28 GHz: 1232 MHz 32 GHz: 1568 MHz 42 GHz: 2000 MHz • Higher Practical Value: • Regulated, clean spectrum • Contiguous spectrum facilitates optimized RF planning • Area license fee, independent of links number (fixed expense) • Greatly simplifies licensing logistics 6.5 GHz Bandwidth • Superior Performance: • Less affected by multipath, (vs. sub 6 GHz) • Less affected by rain, (vs. 60 GHz) 11

  12. Macro-Cell & Small-Cell Backhaul: Co-Existence in the same Spectrum Blocked Path Blocked Path Re-Use the same spectrum (i.e. 28 GHz) & freq. channels, with minor, coordinated RF Planning Highly uncorrelated backhaul layers! Cross-layer radio signals are blocked or absorbed 12

  13. Any Architecture Microwave Solution The solution supports any type of PtP connectivity Realizes Any Network Architecture: Multi-hop, Relay Extensions, PtP Rings MW units can be also configured as PtMP, for optimized connectivity 13

  14. Reaching Any Location: Multipoint Extensions Multipoint Nodes: Realize multihop PtP and/or PtMP connectivity Multipoint Nodes Efficiently Extend Connectivity Along the Street Canyons Buildings may obstruct direct LOS links between adjacent mall-Cells i.e. PtP  PtMP Relay: Extends reach to the “hidden” Small-Cells, efficiently 14

  15. Street-level Multipoint Extensions Small-Cell PtP 2nd Hop PtP 3rd Hop PtMP 1st Hop PtMP 2nd Hop Fiber PtMP 1st Hop Small-Cell Flexible, Scalable, Easy-to-Deploy Architecture 15

  16. Raising The Value of Multipoint Connectivity Multipoint Nodes: A single unit (system) realizes: PtP or PtMP functionality A common radio greatly facilitates: RF planning, network design, equipment deployment, and operations Software Define Radio efficiently realizes different connectivity roles: PtMP Hub, PtMP Terminal, PtP Unit Software Defined Radio is a Key Component for Realizing Efficient Multipoint Extensions 16

  17. Connecting Small-Cells Optimally: PtMP • PtMP Value: • N+1 Units for N Links • Only 2 Units on Aggregation Lamppost • PtMP Value: • Single Channel per Aggregation Point (Hub) • Dynamic Bandwidth Allocation • Centralized QoS PtMP Value: New Links Require only Terminal Installation Adopting PtMP Connectivity Greatly Reduces the Equipment BoQ & Footprint 17

  18. MW & LOS Performance Certainty • NLOS Planning: • Statistical Link Gain • Unknown Interference • Uncertain, varying, unreliable performance MW LOS Planning: Deterministic planning delivers predictable results Intelligent mechanisms can mitigate the street-level multipath effects MW Deterministic Planning Guarantees “Deploy-&-Forget” Performance MW LOS Performance: Carrier-Grade, 99.99% Availability, Max Capacity (1024 QAM) 18

  19. Clutter Absorbs MW Co-Channel Interference TS Rx @ F1 TS Rx @ F1 F1 Channel Blocked Interfering Path F1 Channel Blocked Interfering Path PtMP Tx @ F1 PtMP Tx @ F1 Terrain clutter blocks Interfering Paths and absorbs Multipath  No Interference! 19
