Amsterdam Project Overview

Amsterdam Locations • Pilot project conducted in

Amsterdam, where over 160 small

cells were installed on bus shelters,

and connected mainly using fibre

• Deployment Phases:

– 30 small Cells live: April 2014

– 160 small Cells live : August 2014

• Design of the Backhaul solution

based on:

– Street furniture assets

– Fibre Design

– Backhaul & Services Design

Fibre Design Foundations

• Fibre double-head ring topologies

• Rules per fibre string:

– end points at existing macro sites

– two different end points per string

– a maximum number of small cells in the string

– short distance between sites

– no common fibre paths between strings

– no more than two small cell at a dead end

• Fibre design provided a high reliability and

capacity backhaul for the small cells,

keeping a live connectivity even in case of

fibre cuts and/or aggregation equipment

faults

• no or low power is required

• high reliability (no active

components)

• very high dedicated

capacity per small cell

(full 1 Gbps)

• low latency and jitter

• very cost efficient solution

(no OpEx and very low

CapEx).
