LONG HAUL MULTI-GIGABIT MICROWAVE: A NEW APPROACH

6,018 views

Published on

As the data capacity demand on mobile phone and other wireless operator networks booms, their telecom backbones, or backhaul infrastructures, have struggled to keep pace. To get high volumes of data from coast to coast, operators have in more recent times relied on fiber optic technology for their voice and data traffic. However, for these long-haul operations, fiber lacks practicality, flexibility, cost effectiveness, security and quick time-to-market. Increasingly, operators are turning to the original long-haul telco solution to meet all these needs: microwave radio.

LONG HAUL MULTI-GIGABIT MICROWAVE: A NEW APPROACH

  1. 1. LONG HAUL MULTI- GIGABIT MICROWAVE: A NEW APPROACH An Advanced Technology Webinar From Aviat Networks 14 August 2013
  2. 2. AVIAT NETWORKS WHAT WE WILL COVER TODAY • Typical Trunking Microwave characteristics • Split-Mount Trunking Microwave Solution • Reducing Trunking Total Cost of Ownership • Conclusions and Q+A • The drivers for Trunking Microwave applications • The Impact of Tower Outsourcing on TCO
  3. 3. TRAFFIC EXPLOSION
  4. 4. Commercial LTE Network Launches (cumulative) Source: GSA
  5. 5. How to meet expanding capacity demands?
  6. 6. AVIAT NETWORKS In many cases fiber is just not an option:  Too expensive  Not practical  Too vulnerable
  7. 7. AVIAT NETWORKS Long Haul, or Trunking Microwave has formed the backbone of networks around the world.
  8. 8. AVIAT NETWORKS HIGH CAPACITY, GUARANTEED • Multi-channel microwave systems are key for providing guaranteed high capacity links for long-haul and aggregation applications • New techniques can help, but don’t fit the application: • Higher modulations >1KQAM • MIMO • Ethernet Optimization, eg: Header Compression, etc • Asymmetric links
  9. 9. ASSURED CAPACITY EXPANSION REDUCE SITE COMPLEXITY SIMPLIFY DRAMATICALLY LOWER TCO SAFEGUARD SAVE
  10. 10. AVIAT NETWORKS Antenna Waveguide Indoor Unit ALL-INDOOR TRUNK RADIOS • All-indoor trunking radios were originally designed for N+1 SDH applications • Supported features generally lag the rest of the microwave market by >12 months • Consist of a full equipment rack, with additional clearance needed for waveguide connections • Connected to antenna(s) by semi-rigid, elliptical waveguide – requires pressurization, dehydration and regular maintenance
  11. 11. AVIAT NETWORKS 4 Gbit/s 2 Gbit/s 3 Gbit/s 1 Gbit/s 40 GHz30 GHz20 GHz10 GHz All-Indoor Trunking
  12. 12. AVIAT NETWORKS 4 Gbit/s 2 Gbit/s 3 Gbit/s 1 Gbit/s 40 GHz30 GHz20 GHz10 GHz Most effective for high- capacity applications between 2 and 4 Gbit/s All-Indoor Trunking
  13. 13. PROBLEM IS, TRUNKING RADIOS ARE BIG… REALLY BIG.
  14. 14. SO YOU’LL NEEDS ONE OF THESE…
  15. 15. AVIAT NETWORKS ALONG WITH A LARGE GENERATOR (OR TWO)… AND A LOT OF FUEL
  16. 16. AVIAT NETWORKS AND ALSO ONE OR MORE OF THESE BEASTS…
  17. 17. AVIAT NETWORKS SPLIT-MOUNT ACCESS RADIOS • Split-mount access radios can be used for high capacity applications • Usually much more cost effective than indoor trunking radios • Compact indoor unit, suitable for installation in outdoor cabinet • Simple coax IDU-ODU connection • However, combining multiple channels using couplers introduces significant path losses Antenna Coupler ODU Coax Indoor Unit
  18. 18. AVIAT NETWORKS 4 Gbit/s 2 Gbit/s 3 Gbit/s 1 Gbit/s 40 GHz30 GHz20 GHz10 GHz Split-Mount Access
  19. 19. AVIAT NETWORKS 4 Gbit/s 2 Gbit/s 3 Gbit/s 1 Gbit/s 40 GHz30 GHz20 GHz10 GHz Split-Mount Access Most effective for access applications <1Gbit/s
  20. 20. AVIAT NETWORKS Antenna Waveguide Coax Indoor Unit OBU ODU SPLIT-MOUNT TRUNKING RADIOS • Combines the best of both worlds • Environmentally sealed OBU, containing channel-specific filters and branching • Low-loss combining of 4x ODUs onto a single- or dual-polarized antenna • Mounted close to antenna – no waveguide loss • No pressurization needed • ODUs easily removed and replaced for maintenance
  21. 21. AVIAT NETWORKS 4 Gbit/s 2 Gbit/s 3 Gbit/s 1 Gbit/s 40 GHz30 GHz20 GHz10 GHz Combining the best features of indoor trunking and split- mount access Split- Mount Trunking
  22. 22. SO THAT THIS… CAN EASILY FIT INTO ONE OF THESE…
  23. 23. OR EVEN THIS…
  24. 24. AVIAT NETWORKS ANOTHER STEP ALONG THE PATH TO SUSTAINABILITY
