Siklu's presentation for the Purdicom Open Day - Gigabit to the Home - Fixed Wireless Access in mmWave

1. Gigabit to the Home
Fixed Wireless Access in mmWave

Siklu Communications
• Introduction to mmWave
• Gigabit to the home

2. Fixed Wireless Access
• Earlier attempts at GTTH
• Naughties (LMDS,…)
o WiMAX
• Challenges
o Performance as good as wireline
o Comparable or better cost
o Plenty of spectrum
• mmWave (Siklu)– delivers on these challenges

3. 3
The Fixed Wireless Spectrum
Sub-6 Microwave mmWave

4. 4
V-band
• Up to 7GHz: 57-70GHz
• License exempt
E-band
• 10GHz: 71-76GHz, 81-86GHz
• Licensed (£50)
mmWave in UK

5. • Abundant spectrum
• Narrow beam-widths
• Line of sight
• Link distance
Abundant spectrum
• Uncongested
• Wide channels available (2GHz)
 Gigabit throughputs (10Gbps)
Characteristics of mmWaves
Sub-6 Microwave mmWave

6. • Abundant spectrum
• Narrow beam-widths
• Line of sight
• Link distances
Narrow beam-widths
• “Pencil beams” (0.5 to 2.5)
• No interference
• High frequency reuse
• Secure transmission
• Stability essential when <1
Characteristics of mmWaves

7. • Abundant spectrum
• Narrow beam-widths
• Line of sight
• Link distances
Line of sight
• Clear line of sight is essential
• Negligible Fresnel zone

8. • Abundant spectrum
• Narrow beam-widths
• Line of sight
• Link distances
Link Distance
• V-band additionally attenuated by the
oxygen in the air
• V-band and E-band attenuated by
rain
• Effective distances:
o V-band: up to ~1Km
o E-band:
•up to ~3Km for 10Gbps
•Longer for lower air
capacities
•Longer with overbuild ~10Km
Characteristics of mmWaves

9. Atmospheric Absorption
• Oxygen attenuation at 71-76/81-
86GHz
o ~ 0.5dB/Km
o Negligible effect
• Oxygen attenuation at 57-64GHz
o Up to 15dB/Km
o Limited distance, suitable for dense
urban areas

10. Factors that count
• Attenuation due to rain
• Excellent long-term statistics available,
e.g., ERA40: ECMWF’s database based
on 45 years of rain data (1957-2002)
• Oxygen absorption (V-band only)
Factors that don’t count
• Interference
• DFS
• Multipath due to surface reflection
• Attenuation (flat fading)
• Distortion (selective fading)
• Depolarization
• Fading due to beam spreading
• Diffraction due to obstructions

16. Gigabit to the home
Fibre extension: E-band
Access V-band
• Inexpensive chipset
• 802.11ad (Wigig)
• 802.11ay (proposed enhancement)
• Terragraph
• Small footprint
• Beamforming, simplifies installation – sector coverage
• Topology
• Ptp with redundancy (rings)
• Ptmp with redundancy (multiple APs)
• Ptmp without redundancy

17. Sector coverage with narrow beams

18. 18
Network example: Utah, USA
ptp 60GHz with ring protection
Ethernet Ring Protection (ERP), switching time <50ms

19. 19
Network example: Georgia, USA
ptmp 60GHz
359/359 homes connected (100%)
16x poles (average 22 homes/pole)
All on fiber route
53x APs sectors (90⁰) + 359 terminals (average 7 homes/BU,
3.3 APs/Pole)

20. Building the business case
• Target Price of £500 per property connected
• Dramatically lower cost of homes passed
• Lower TCO with Pay as you grow enabling speculative deployment
• Low cost installation – self install and drop ship with zero touch config
Alexa self install
