1 LONG HAUL MULTI- GIGABIT MICROWAVE: A NEW APPROACH An Advanced Technology Webinar From Aviat Networks 14 August 2013

2 WHAT WE WILL COVER TODAY The drivers for Trunking Microwave applications Typical Trunking Microwave characteristics Split-Mount Trunking Microwave Solution Reducing Trunking Total Cost of Ownership The Impact of Tower Outsourcing on TCO Conclusions and Q+A

3 TRAFFIC EXPLOSION

4 Commercial LTE Network Launches (cumulative) Source: GSA

5 How to meet expanding capacity demands?

7 In many cases fiber is just not an option: Too expensive Not practical Too vulnerable

8 Long Haul, or Trunking Microwave has formed the backbone of networks around the world.

9 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

10 SIMPLIFY REDUCE SITE COMPLEXITY SAVE DRAMATICALLY LOWER TCO SAFEGUARD ASSURED CAPACITY EXPANSION

11 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 Antenna Waveguide Indoor Unit

12 4 Gbit/s 3 Gbit/s All-Indoor Trunking 2 Gbit/s 1 Gbit/s 10 GHz 20 GHz 30 GHz 40 GHz

13 4 Gbit/s 3 Gbit/s 2 Gbit/s All-Indoor Trunking Most effective for highcapacity applications between 2 and 4 Gbit/s 1 Gbit/s 10 GHz 20 GHz 30 GHz 40 GHz

14 PROBLEM IS, TRUNKING RADIOS ARE BIG REALLY BIG.

15 SO YOU LL NEEDS ONE OF THESE

16 ALONG WITH A LARGE GENERATOR (OR TWO) AND A LOT OF FUEL

17 AND ALSO ONE OR MORE OF THESE BEASTS

18 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 Antenna Coupler ODU Coax Simple coax IDU-ODU connection However, combining multiple channels using couplers introduces significant path losses Indoor Unit

19 4 Gbit/s 3 Gbit/s 2 Gbit/s 1 Gbit/s Split-Mount Access 10 GHz 20 GHz 30 GHz 40 GHz

20 4 Gbit/s 3 Gbit/s Most effective for access applications <1Gbit/s 2 Gbit/s 1 Gbit/s Split-Mount Access 10 GHz 20 GHz 30 GHz 40 GHz

21 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 Antenna Waveguide Coax OBU ODU No pressurization needed ODUs easily removed and replaced for maintenance Indoor Unit

22 4 Gbit/s 3 Gbit/s 2 Gbit/s 1 Gbit/s Split- Mount Trunking Combining the best features of indoor trunking and splitmount access 10 GHz 20 GHz 30 GHz 40 GHz

23 SO THAT THIS CAN EASILY FIT INTO ONE OF THESE

24 OR EVEN THIS

25 ANOTHER STEP ALONG THE PATH TO SUSTAINABILITY

26 SYSTEM GAIN COMPARISON Split-Mount Trunking All-Indoor Trunking Split-Mount Access Tx Power Output dbm Rx Threshold (10-6 BER) dbm Branching/Coupler Loss db Antenna connection loss db System Gain db (-7dB) 83 (-9.5dB) * Based upon system configuration for 7GHz / 28MHz / 256QAM / 4+0 ACCP, No SD 7 db Advantage = one full antenna size per link

27 PURCHASE PRICE Installation Maintenance Training Upgrades Spectrum fees Power usage Tower costs Air Conditioning costs

28 VENDOR SELECTION CRITERIA TCO and other OPEX drivers rated highest, above purchase price 1 = most important Microwave Strategies and Vendor Leadership: Global Service Provider Survey, July 29, 2013

30 INFRASTRUCTURE OUTSOURCING/SHARING Network outsourcing or sharing becoming common for operators seeking to reduce costs and focus operations Active - spectrum, switches, antenna, etc Passive - tower, shelter, power supply, batteries, aircon, etc) Backhaul leased capacity (over fiber and/or microwave)

31 TCO COSTS - EXAMPLE CAPEX (Initial) Microwave Equipment Price Spares CAPEX (Recurring) S/W Upgrades for Capacity Expansion OPEX (Initial) LOS and Site Survey Site Development and Preparation Design (engineering services) Installation & commissioning Field corrective maintenance Repair and return (MLA fees) Spectrum License (Initial Free) OPEX (Recurring) Spectrum License Annual Fee Tower lease (x' antenna) Power, Cooling and Other Maintenance

32 Original Antenna Diameter, ft TCO SAVINGS BY REDUCING ANTENNA SIZE ,000 20,000 30,000 40,000 5 Year TCO Saving, USD The larger the antenna, the bigger TCO Savings

33 MICROWAVE TCO - 5 LINKS, INCLUDING TOWER

34 MICROWAVE TCO - 1 LINK, TOWER EXCLUDED

35 MICROWAVE TCO - 1 LINK, WITH LEASED TOWER

36 MICROWAVE TCO - 1 LINK, WITH LEASED TOWER CAPEX IS ONLY A MINOR CONTRIBUTOR FOCUS ON OPEX IS MUCH MORE IMPORTANT!

37 COMPARATIVE TCO ANALYSIS CAPEX TCO OPEX

38 COMPARATIVE TCO ANALYSIS Major drivers: Antennas size and number Site footprint (container versus a cabinet) Power consumption Air conditioning Up to 30% TCO Saving with Split-Mount Trunking

39 SIMPLIFY REDUCE SITE COMPLEXITY Site cabinets, instead of shelters Reduced site power needs Smaller antennas Reduced tower loading No waveguide or pressurization

40 SAVE DRAMATICALLY LOWER TCO No need for expensive shelters Lower equipment CAPEX Higher system performance Site running costs slashed Smaller antennas = lower tower lease charges

41 SAFEGUARD ASSURED CAPACITY EXPANSION Simple capacity upgrades Guaranteed capacity Take advantage of the latest radio and Carrier Ethernet features Common platform with access radio

42 AVIAT STR 600 New Split-Mount Trunking Solution Outdoor Branching Unit (OBU) ODU600T high performance ODUs High system gain Simple sparing (one ODU per band) Now shipping in frequency bands from 5 to 11 GHz worldwide

43 IN CONCLUSION Split Mount Trunking combines the best of both worlds Ultra-high capacity links with the convenience of split-mount Enables dramatically lower costs Optimize assets in preparation for tower outsourcing Guaranteed capacity without compromise SIMPLIFY, SAVE, SAFEGUARD
