KEY
Number
of Cells
§ Total cell estimate for
Toronto ~ 25K cells
§ Mean cells per census tract
= 21 cells
§ Mode cells per census tract
= 16 cells
§ Min cells per census tract
= 0
§ Max cells per census tract
= 139
§ Cell numbers based upon an ITU model for 5G.
§ Calculations use population density and area of
census tract from Canada Census Statistics.
§ Assumes no mm wave transmission in areas of
high density
§ Assume use of MIMO signal processing
techniques
§ No daytime population density increase
considered in this initial analysis.

Optimising Fiber Assets Through Fixed-Mobile Convergence
Reuse of Infrastructure for
Small Cell Deployments
A key challenge for small cell
deployments is connectivity
Connect small cells reutilizing
FTTH infrastructure
Dynamic Bandwidth
Allocation
Traffic load varies over time and
location but network resources
are fixed
Dynamically allocate wavelength
resources depending on
bandwidth demand
Network Sharing

Operator 2
Network sharing between
operators exists today
Provide multi-operator
network capabilities
