⌘History of wireless communications

From1Gto3G.png

while 1G and 2G were all about radio interfaces,

  • 3G and Beyond 3G (B3G) are all about services
  • 4G is using mobile broadband everywhere
  • 5G will be truly heterogeneous network

⌘Speed of technology

TechnologyAdvances.png

  • "There might be a need for 5 computers" (1943 Watson(?), 1951 Hartree)
  • Mobile: NMT, GSM, GPRS, EDGE, UMTS, 3G, HSDPA, SMS, EMS, MMS,... DVB-H,...

⌘Expectations towards global coverage

  • According to Ericsson, Mobile Technologies are available for 50% of the world's population (2013), and the coverage will increase to 75% by 2017.
  • According to Internet.org (Facebook, Opera Software, ....), only 1/3 of the world's population has access to the Internet (2013).
  • An extrapolation by the Basic Internet Foundation points out that even in 2017 about 45% of the population will not have access to Internet, mainly due to affordability. Thus they promote the free access to basic information of the Internet, being text and pictures.
