  3. About Us • Wireless Strategies management team has over fifty years experience in the communications industry including: Fixed Electronic Satellite Cellular Microwave Warfare Communications

  4. The Problem Insufficient Spectrum

  5. Wireless Operator’s View “A wireless operator without enough spectrum is like a body without enough blood… If you don't have enough blood you're going to face major medical challenges. Likewise, Wireless operators will need more spectrum to be able to offer new services and applications.” -Ali Tabassi, Vice President Innovative Technologies, Sprint-Nextel Wireless Strategies Inc.

  6. Equipment Manufacturer’s View In 2006, the CEO Council (CEOs from Motorola, Intel, IBM, HP, Dell etc.) called on the U.S. government to find more spectrum for use as new applications emerge. Wireless Strategies Inc.

  7. The Problem • The amount of microwave spectrum is finite and has been assigned. • It takes many years for the FCC to go through the regulatory process of re-assigning spectrum (usually from Point-To-Point Fixed to Multipurpose, PTMP/Mobile). Wireless Strategies Inc.

  8. Solution The Reuse of Existing Licensed Spectrum by the Licensed Operator without causing Additional Interference. Wireless Strategies Inc.

  9. Perfect Antenna

  10. Path Coordination In a Perfect World there is only the Main Lobe, and therefore only the Main Lobe has to be considered

  11. The Reality

  12. Path Coordination In the Real World there are Side Lobes and therefore the Side Lobes must be Concurrently Coordinated with the Main Lobe.

  13. The Status Quo Paths designed for and operated with Legacy Equipment have not put the Antenna Side-Lobe Radiation to Productive Use.

  14. The Industry Opportunity Use Emerging (IEEE 802.16 – WiMAX – TDD – Smart Antenna) Technologies to Put the Antenna Side-Lobe Radiation to Productive Use Under Existing Rules without Causing Additional Interference.

  15. Win-Win Opportunity • Wireless Carriers: New Customers, Higher Revenues, Higher Profits/Lower Costs and Shorter Service Provisioning Times • Spectrum Managers: Increase in Prior Coordinations and Monitoring Services, Increased Revenues and Profits • FCC: Supports the Commission’s goal of Maximizing the Effective use of Spectrum. • Public Interest: More Competition for their Business, More Features and Lower prices

  16. Business Case

  17. Legacy Example (6GHz) • One Freq Pair • One Path • Reqd Capacity 134Mbps • Min Reqd Load 67Mbps • One Major Subscriber • Operating Load 89Mbps • Mo Rev. $6,000 • Mo PBT $600

  18. Concurrently Coordinated Example (6GHz)

  19. Concurrently Coordinated

  20. Concurrently Coordinated Example (6GHz) • One Freq Pair • Six paths • Reqd Capacity 134Mbps • Min Reqd Load 67Mbps • One Major Subscriber • Five Minor Subscribers • Actual Load 134Mbps • Mo Rev. $14,400 • Mo PBT $8,600

  21. Compelling Business Case • Legacy • One Freq Pair • One Path • One Major Subscriber • No Minor Subscribers • Traffic Load 89Mbps • Mo Rev. $6,000 • Mo PBT $600 • Concurrent Coordination • One Freq Pair • Six Paths • One Major Subscriber • Five Minor Subscribers • Traffic Load 134Mbps • Mo Rev. $14,400 • Mo PBT $8,600

  22. Compelling Business Case • Legacy • One Freq Pair • One Path • One Major Subscriber • No Minor Subscribers • Traffic Load 89Mbps • Mo Rev. $6,000 • Mo PBT $600 • Concurrent Coordination • One Freq Pair • Six Paths • One Major Subscriber • Five Minor Subscribers • Traffic Load 134Mbps • Mo Rev. $14,400 • Mo PBT $8,600 How do WE Get from Here to There

  23. Innovation The FCC has consistently promoted the national policy set forth in Section 257 of the Communications Act by enabling industry operators and equipment providers to maximize the efficient use of spectrum and facilitate innovative services and product offerings.

  24. Facilitating Innovation The Commission’s Rules specify the technical requirements (not how the technical requirements are met)

  25. Regulations Specify • The Shape and Size of the Radiation Pattern Envelope (Tx power x antenna gain) and the location from which it emanates. • They do NOT specify HOW* it is achieved (TWTA, SSA with a Parabolic dish with a dipole, a Flat Panel, or a Multi-Array, etc). *By not specifying HOW, the Commission allows and encourages industry to innovate.

  26. Microwave Transmission/Reception System A Microwave Transmission/Reception System Consists of two pieces: • A Signal Generator/Receiver (Transceiver) • An Antenna consisting of two pieces • i. Primary Element - determines the RPE • ii. Microwave radiator(s) such as a dipole or horn, etc.

  27. T/R T/R Transceiver Regulations • Do not specify physical dimensions • Do not specify where the Transceiver(s) are located

  28. Antenna Regulations • Do not specify physical dimensions • Do not specify the type of Antenna or where the Microwave Radiator Element(s) are located • Do not specify the RPE of the Radiating Element(s) -By not specifying HOW, the Commission allows and encourages industry to innovate.

  29. Part 101-115 of the Rules Antenna Radiating Elements Not Specified Feed Horn with Convex Reflector Physical Location Not Specified RPE Not Specified Dipole RPE Not Specified Physical Location Not Specified

  30. Parabolic Dish with Feed Horn and Convex Reflector T/R

  31. Parabolic Dish with Dipole T/R

  32. Transceiver and Radiator Element’s Location and RPE Not Specified for a Dish Antenna

  33. Transceiver and Radiator Element’s Location and RPE Not Specified for a Multi-Array Antenna

  34. Transceiver and Radiator Element’s Location and RPE Not Specified for a Multi-Array Antenna

  35. T/R Transceiver and Radiator Element’s Location and RPE Not Specified RPE Not Specified Dipole Physical Location Not Specified

  36. 50dBm 70dBm 10dBm 30dBm The Regulation EIRP (Std A) Stand alone Radiation Element EIRP Tx Po 30dBm, Dipole Gain 2dBi

  37. 20dBi 40dBi -20dBi 0dBi The Regulation RPE

  38. Antenna System Regulations The location and radiation pattern of an antenna system’s radiator(s) has never been specified and has never been a cause of concern, because it is the level of Interfering signal “I” arriving at the victim receiver from the interfering system in its totality that is used for coordination interference calculations, C/I and T/I (This applies to any type of antenna system and path)

  39. Prior Coordination Boundary Existing Path Site B Site A Carrier C C/I or T/I Interference I Site D Site C Proposed Path

  40. 50dBm 70dBm 10dBm 30dBm Log Polar Plot of the RPE of a Std A Requirement for Any Type of Antenna Around Site C in dBm Tx Po 30dBm

  41. Linear Distance Plot of the Interference Contour Around Site C for Any Type of Std A Antenna (For a given Victim receiver antenna gain)

  42. Victim Antenna Main Lobe 10 deg off Site C Antenna Ctr Line Victim Antenna Main Lobe 20 deg off Site C Antenna Ctr Line Victim Antenna Main Lobe 40 deg off Site C Antenna Ctr Line Victim Antenna Back Lobe Prior Coordination Boundary 125 miles Except within 5 deg of Ant Ctr line when it is 250 miles

  43. Legacy Network Everything Required to perform a Coordination Study is known

  44. Linear Distance Plot of the Interference Contour Around Site C for a Std A Parabolic Dish Antenna (For a given Victim receiver antenna gain)

  45. Std A Parabolic Dish Prior Coordination Boundary Existing Path Site B Site A Carrier C C/I or T/I Interference I Site D Site C Proposed Path Interference Contour I (For a given Victim Rx Ant Gain)

  46. Smart Antenna with Distributed Radiators • A smart antenna with distributed radiators is an antenna system that combines an antenna array with a digital-processing capability to transmit in an adaptive spatially sensitive manner so as to always maintain the Interference at the Victim receiver(s) input from any Distributed Radiating Element ( IDRE ) less than the coordinating Interference ( I ). Therefore, the interference signal IDRE is not a cause of concern because it is the level of Interfering signal I that is dominating the coordination interference calculations, C/I and T/I .

  47. Concurrently Coordinated Network Everything Required to perform a Coordination Study and to Maintain IDRE < I is known

  48. Linear Distance Plot of the Interference Contour Around Site C for a Std A Smart Antenna with Distributed Radiators (For a given Victim receiver antenna gain)

  49. Std A Smart Antenna with Distributed Radiators Prior Coordination Boundary Existing Path Site B Site A Carrier C C/I or T/I Interference I Site D Site C Proposed Path Interference Contour I (For a given Victim Rx Ant Gain)
