This presentation was used in the 'What to do until the fibre arrives' webinar.
The presentation examines how mobile operators can lower backhaul costs by using wireless backhaul now, and investing in fibre later.
This strategy uses wireless as an interim solution for operators planning to move to fibre that need to increase backhaul capacity, but cannot move to fibre today.
The presentation shows over ten years, operators can save 27% when deploying wireless first, and building a fibre network later - or save 31% when deploying wireless initially and leasing fibre later.

•Can wireless backhaul ease the transition to fibre?
Lance Hiley
VP Marketing, Cambridge Broadband Networks Limited
•Why point-to-multipoint (PMP) is so good for this approach
•Operator backhaul deployment examples

7. Wireless backhaul options (licensed spectrum)
Conventional PtP
• For: High capacity
• Against: Coverage awkward, spectrum opex, high installation costs
E-band
• For: High capacity
• Against: High capex and opex
LoS multipoint microwave
• For: Good coverage, low cost of ownership, High capacity
• Against: Requires area-licensed spectrum
Non-line of sight multipoint microwave
• For: Good coverage, low cost of ownership
• Against: Low capacity, spectrum can be expensive

8. Architecture 1: Point-to-Point Microwave Radio, Star Topology
• The most common microwave topology in use today
− For N links, 2N radios
− Dedicated RF channel for each node B served
− Well-suited to constant bit rate traffic
− Well-suited to long links

9. Architecture 2: Point-to-Multipoint Microwave Radio
• The fastest growing microwave topology today
− For N links, N+1 radios
− Shared RF channel amongst all node Bs served
− Well-suited to variable bit rate (bursty) traffic
− Well-suited to dense environments

2 ODUs per link 3 hub ODUs plus 1 RT per link
2 truck rolls per link added 1 truck roll per link added
2 antenna rentals per link 3 hub site rental plus 1 per link
2 units power per link 3 unit power per hub plus 1 per link
• 160 ODUs/truck rolls/antennas • 93 ODUs/truck rolls/antennas
• 160 units of power consumption • 93 units of power consumption
At 80 Links = PMP Saving of 67 ‘units’

12. Opex analysis: using UK published leased fibre prices
• Leased fiber pricing used in the Cumulative capex and opex, Year 5
base case is higher than many
$120,000
developed countries
$100,000
Model strives to use median values,
Per RAN site
including developed and emerging $80,000
countries, which pushes prices up $60,000
$40,000
• Using UK published retail
$20,000
pricing: Fiber 40% more expensive
than PMP, 27% less expensive $-
than PTP PMP PTP E-band Fiber, leased

• In competitive markets, PTP is

16. New fibre deployment: Urban Ring
•Early stage fibre deployment limited to urban rings
•PMP extends reach of fibre rings quickly, with similar
performance
•Delivers ubiquitous coverage quickly
