1. Optimizing Backhaul for Picocells in 4G Networks Amir Makleff President and CEO BridgeWave Communications

3. The general trend of higher bit rates/shorter distances is widely recognized2 © BridgeWave Communications www.bridgewave.com | 1-866-577-6908 2

5. Network holes between Macro Base Stations, originate from geography, building layout or legacy network planning

6. These “holes” yield slow data rates and dropped calls

7. Solution:

9. Large number of nodes to achieve coverage

10. Different types of nodes in a variety of locations:

11. In buildings

12. Roof tops

13. Street-level

14. Light or utility poles

15. High capacity

16. Propagation in urban canyons

17. Aesthetic fit (inconspicuous)

19. Low Opex/recurrent fees (e.g. license)

20. Small deployed footprint

21. Aesthetic fit in urban environments

22. Bit rates expandable up to 1 Gbps

23. To support mesh and daisy chaining

24. Short deployment lead time5 © BridgeWave Communications www.bridgewave.com | 1-866-577-6908 5

26. Abundance of spectrum

27. High capacities

28. Attractive licensing & highly-directive transmission

29. Natural immunity to interference

30. High frequency reuse

31. Minimal frequency planning

32. Short wavelength

33. Small size of hardware and integrated solutions

34. Quick deployment

36. V-band (“60GHz”) 7GHz (57-64GHz)

37. Unlicensed (e.g., USA, UK)

38. E-band (“80GHz”) 10GHz (71-76GHz and 81-86GHz)

39. Light-licensing (e.g., USA, UK)

41. Absorption of O2 ~14dB/Km

42. Also rain

43. 1-2Km for 1Gbps links @5’9s

44. 80GHz:

45. Rain

46. 2-4Km for 1Gbps links @5’9s

47. Neither is impacted by:

48. Multipath fading due to narrow beams and relatively short links

49. Fog (<0.4dB/Km)60 GHz Excessive rain150mm/h Heavy rain25mm/h Fog Drizzle0.25mm/h 80 GHz

51. Typical examples:

52. Implications:

53. Security

54. Low probability of detection (LPD)

55. Low probability of intercept (LPI)

56. High interference immunity

57. High frequency reuse

58. “No” multipath5.8 GHz = 1,140’ wide @ 1 mi 60 GHz = 128’ wide @ 1 mi

60. Narrow beam width

61. Oxygen absorption at 60GHz.

62. At 60GHz, an infinite linear cascading of links may be achieved using only one pair of FDD frequencies and 2 polarizations:

64. Street-level deployment requires a different approach:

65. Aesthetic

66. Concealed / disguised

68. Scalable capacity >1Gbps

69. Distance scalable from picocell to macrocell backhaul

70. Fast and simple deployment

71. Good frequency reuse

72. Good interference immunity

73. Minimal frequency planning

74. Good fit for urban environment

75. Aesthetic, “concealed” solution

76. Small footprint

77. Low Cost

78. Low Total Cost of Ownership per bps

79. Minimal OpEx and recurring fees (e.g. license)

80. Challenges

82. Including fiber, microwave, millimeter wave, etc.

83. Millimeter Wave radios offer distinct advantages for small cell backhaul:

84. High capacity links

85. Abundance of spectrum

86. Good urban fit

87. Fast and inexpensive deployment

88. 60GHz solutions ideal for small cell deployments and is a proven technology for similar applications© BridgeWave Communications www.bridgewave.com | 1-866-577-6908 1-408-567-6900
