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

26

• 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.

27
