ICTs and Climate Change
 ICTs are part of the problem…
 ICTs contribute 2-3% GHG emissions
 …but part of the solution:
 Energy efficient devices, applications and networks
 ITU and Climate Change




Methodologies for calculating impact of ICTs
Energy reduction e.g. NGN
New Environment and Climate Change study group
Developing standards for smart technologies,
allocating spectrum for satellite remote sensing,
intelligent transport systems, teleconferencing…

transactions and economic development
 Cost of cyber-attacks in the billions annually
 Confidence and security in ICT basis for global
Information Society
 Cybersecurity cornerstone of development
 Legal, technical and institutional challenges to
strengthen cybersecurity

Accessibility
 ITU first to start accessibility studies - 1991
 1994 the international text telephone standard,
Recommendation ITU-T V.18, was published
 Since then, ITU’s accessibility experts have
helped to incorporate accessibility needs into
standards for:
 Multimedia: IPTV
 teleconferencing
 Next generation networks (NGN)
 accessibility check list
 On-line toolkit for policy makers, regulators etc

IMT Background
 Broadband multimedia
 First IMT standards – IMT-2000
 Now more than a billion IMT-2000
(3G) subscribers
 IMT-Advanced
 Global platform for the next
generation of mobile services
 Fast data access, unified messaging
and broadband multimedia – exciting
new interactive services
Committed to Connecting the World
What is IMT-Advanced?
 IMT-Advanced systems will:
 Provide access to a wide range of services
supported by (increasingly packet-based)
mobile and fixed networks.
 Support low to high mobility applications
and a wide range of data rates in multiple
user environments.
 Provide for high quality multimedia
applications within a wide range platforms
with significant improvement in
performance and QoS.
Committed to Connecting the World
Key features

ITU goal
 Emphasize benefits of fixed wireless access in
remote and sparsely-populated regions
 Adopt a cooperative approach
 Maximize the degree of commonality and
harmonization
 Facilitate interworking
 Promote competition
 Any new technology or standard needs to be
interoperable, and to be able to interface and
work with other technologies
Committed to Connecting the World
Mobile Broadband – ITU Stats*
 Global growth of 91.5% from beginning of
2007 to beginning of 2008 (from 136 million
to 260 million subscribers)
 Growth of 200% over same period in Africa,
and 500% in Arab States
 Grew 10-fold in Sri Lanka. 30-fold in Bulgaria
*
Figures refer to number of subscribers to mobile cellular networks
with access to data communications at broadband speeds, such as
WCDMA, HSDPA, CDMA2000 1xEV-DO, CDMA 2000 1xEV-DV etc.
