4. Mobile Market trends And
Drivers
› Mobile data traffic growth:
– 15-fold growth between 2012 and 2017,
mainly driven by video5
› By 2015, 90% of internet traffic will be
video1
› Tablet users are heavy consumers of
video outside the home2
› Mobile broadband subscriptions up:
– From 900M in 2011 to almost 5B in 2016
› Metro densification:
– By 2016, 30% of Earth’s population will live
in less than 1 % of its total land area and
generate around 60% of mobile traffic3
› Wi-Fi devices doubling:
– Shipments of Wi-Fi devices reached nearly 1.1 billion in 2011 and are expected to double by
20154

7. Wifi End-user
scenarios
› Change-over to WiFi is normally in the hands of the end
user.
– Native decision making on smartphones
– WiFi power consumption is still a concern of many users.
› Manual authentication will slow the migration to WiFi off-
load
› Smartphone Apps is a viable solution.

8. Wifi regional rollout
› All operators are reporting some kind of WiFi
strategy.
› Some regional operators are integrating their WiFi
service into the cellular networks.
– SIM authentication.
– WiFi access apps for smartphones.
› Initial attempts to cooperate on the WiFi
infrastructure among operators.
– Preferable from a spectrum and quality of service
perspective.

17. Small Cell backhaul
Strategy
› Most important factors for small cells:
– Location, backhaul, power
› Needed: deployment flexibility
› Fixed Backhaul
– For both indoor and outdoor deployments
– Traditional telecom infrastructure: Copper & Fiber
– Tactical Reuse: Cat5/6, POTS UTP, PON, DOCSIS, DAS, Powerline etc
› Wireless Backhaul
– Mainly for outdoor deployments
– Both licensed and unlicensed spectrum,
Line of Sight and Non/Near-LOS
– New 60GHz & <6GHz options for small cells

21. Heterogeneous Networks
Summary
Heterogeneous Network is about
Capacity and End User Experience
Small cells complement macro layer,
macro functionality is the basis
Inter-layer coordination the key
Improve – Densify – Add
