AA2-Mobile Generations

= ⌘AA2-Mobile Generations =

= ⌘History of wireless communications = 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=
 * "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,...

Comments
Future communication systems, composed of IMT-A (ground), High altitude platform (HAP) and satellite

=%Wireless standardisation forums=
 * ITU-T
 * ETSI
 * IEEE
 * 3GPP (3G Partnership Project) and 3GPP2
 * Bluetooth SIG, zigbee alliance

and a lot of others addressing interworking
 * OMA (open mobile alliance)
 * UMTS forum

=⌘Frequency spectrum=

=⌘Current wireless technologies = Ultra short range
 * RFID, NFC

Vicinity
 * Bluetooth, Wibree, Zigbee, WiMedia,
 * ANT+, Bluetooth Smart (Low Energy)

Local area
 * Wireless LAN, 802.11 family
 * Wireless telephony: DECT (Digital Enhanced Cordless Telecommunications)

Mobile Communications:
 * NMT
 * GSM
 * 3G: UMTS
 * 4G:LTE - IMT-A
 * 5G


 * Mobile satellite communication: Geostationary (Inmarsat A, C, M) or low orbit (e.g. Iridium)

=⌘Trend: Personal Networks=

=⌘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.
