  1. Fixed Wireless Backhaul Applications & Solutions • John Seaman - VP of Sales • Trango Systems, Inc. Complete Solutions

  2. Corporate Overview Leading manufacturer of wireless IP backhaul solutions Focusing on point-to-point microwave backhaul Based in San Diego, California Delivering wireless solutions since 1996

  3. World Class Engineering & Manufacturing Poway, California Facility Experienced engineeering & manufacturing teams Long history of producing RF and IP equipment Strong and close partnership with Broadcom Close working relationship with customers ISO9001 Certification • 30,000 square foot manufacturing facility • State-of-the-art, fully automated SMT lines • Fully Automated Optical Inspection (AOI) capability • Comprehensive system and subsystem testing over temperature

  4. Agenda • PTP & Backhaul Applications • Frequency Planning and Licensing • Case Studies & Success Stories

  5. Backhaul Evolution • Backhaul: Once the “after thought” of the wireless infrastructure • Explosive growth in recent years • 4G & LTE are pushing the limits of existing networks • Today’s MW solutions are more powerful and cost effective than ever • Gigabit & Beyond now possible • Wireless Backhaul is essential to today’s network!

  6. Wireless Backhaul Markets & Applications • Mobile Infrastructure - Carrier Networks - 4G/LTE • Enterprise IT Networks • Service Providers - Fixed Wireless - ISPs - WISPs • Healthcare and Education - Campus Networks • Federal, State and Local Government Agencies - Public Safety • Industrial Wireless Networks - Energy - Utility Telecommunications • Transportation Networks - Shipping - Passenger and Freight • Security - Video Surveillance • Broadcast - Radio - TV - Studio Transmissions

  7. PTP Applications

  8. Licensed bands vs. Unlicensed bands Licensed Unlicensed • Advantages • No risk of interference • Higher capacity • FDD • Lower Latency (<1mS) • Product Reliability • Network Reliability • Disadvantages • Licensing fee • Time waiting for license • Typically more expensive • Advantages • No license required • Quicker deployment • Typically lower cost • Disadvantages • High risk of interference • Typically lower bandwidth • Typically FDD • High latency • Interference causes poor reliability

  9. FCC Licensed Band Frequencies • Channel / Antenna Size Options Conditional certification: User may be required to change out antenna if it causes interference. Smaller antennas may be allowed in coordination. *Higher throughput figure represents max throughput for small packets due to header compression

  10. Spoke Linear Ring Branch Network Design Considerations/Options Ring Backhaul Hub/Spoke Backhaul Linear / Daisy Chain Backhaul Multi Ring / Mesh Backhaul Mixed Backhaul Network

  11. Redundancy Planning • Redundant equipment increases overall uptime and customers perceptions. • Critical capacity. • Backhaul links typically major backbones. • Redundancy Methods • Alternate paths • Redundant Rings • 2+0 or 1+1 Hot standby • Unlicensed under-build • On-hand Spares

  12. Path Planning Considerations • Trango can Help! • Pathcheck App • Customized Path Calculations • Terrain Profiles • Link Budgets • Recommendations on frequencies, antenna size, modulation. • Frequency coordination with Radyn • Path Coordinates • Rain Region • Line of Sight • Fresnel Zone • Licensing Coordination

  13. Path Considerations Millimeterwave Rain Attenuation Antenna Sizes, Types, Alignments Atmospheric Multipath • Path Assessment • Link Performance Calc. • Link Availability Calc. (Rain Fade) • Frequency Study • Infrastructure (Shelter, Power, Security) • Antenna System (Structures, Aesthetics) • Grounding & Safety Refraction, k-Factor Path Clearance Frensel zone Feeder Losses Reflections Shelter

  14. Pathloss Terrain Profile 14

  15. Rain Regions – North America (Crane Model)

  16. Adaptive Coding & Modulation (ACM) • Modulation can upshift or downshift without any loss of traffic – 100% hitless • Increases link reliability

  17. Sample Pathloss Report • Location data • Antenna & Radio data • Free space loss • Projected RX level • Fade margin • Rain rate & attenuation • Availability Prediction

  18. Mobile Application for IP Backhaul Planning • GPS mapping with site placement and terrain data • Max Tx power and antenna size based on selected frequency band, regulatory region, channel bandwidth and rain region • ITU rain region, Terrain and Fresnel zone profiles • Site photographs, Map view of the point-to-point link • RF link statistics displayed in real time  • Small Packet Capacity (Mbps), Large Packet Capacity (Mbps) • Max Tx Power (dBm), Expected Rx Level (dBm) • Rx Sensitivity (dBm), Fade Margin (dBm) • Link Quality, Link Outage (minutes per year) • Availability (% yearly) • Email, print, and import/export of path profiles • Quote request tool

  19. Frequency Coordination • Required site information from Pathloss report, tower call signs, etc. • Analysis against existing and proposed stations (other microwave, satellite, TV relay, etc.) to ensure no interference or performance impact. • Confirm performance matches FCC requirements. • Coordination per path.

  20. FCC Licensing • Form 601 • Double and triple check coordinates, line of site and Fresnel zone for path obstructions • If no issues, submit to FCC • Coordinator notifies other licensees in the area for comment. • Approx. 30 days for notice to be reviewed by licensees. • Pay filing fees to FCC per site. • $470 for new, $270 modification • No fee for gov agencies

  21. Microwave System Form Factors Split-Mount All-Outdoor All-Indoor • Separate Indoor unit (IDU) and outdoor unit (ODU) • IDU Rack mount in shelter • ODU Direct Mount to Antenna • IF Cable (coax) from IDU to ODU • Modem and Radio self contained in outdoor unit • Typical connection via POE or direct fiber up the tower • No rack space required, no coax required. • Modem unit and RFU Unit all housed indoors • Rack Mount • Waveguide installation

  22. Case Studies

  25. Multipurpose Microwave Network – Deployed 2012 Funded by HLS grant Interconnects county facilities and mountain repeater sites Pure IP Network for convergence of LMR (Land Mobile Radio) Next Gen 911 FirstNet Ongoing expansion via various grants Goal to interconnect 14 northern CA Counties and FirstNet Plumas County, CA Public Safety Microwave Network

  26. NG911 IP-based system that allows digital information (e.g., voice, photos, videos, text messages, telematics) to flow seamlessly from the public, through the 911 network, and on to emergency responders. Next Generation911 & FirstNet • FirstNet’s mission is to develop and build first nationwide broadband network dedicated to public safety. • Independent entity operating under guidance of NTIA. • Allocated $7 Billion by the FCC to create the network. • www.firstnet.gov
