DIMETIC, Maastricht 9/10-07_BD3 Wireless technologies and services Microwaves - Radiocommunications 1) Mobile and cordless communications (equipment for terminals and infrastructure) –2G: GSM, 2+ (GPRS, EDGE) –DECT –Bluetooth –TETRA –3G: UMTS, CDMA2000, TD-SCDMA, 3+ (HSDPA) –4G? 2) Components for mobile terminals 3) Mobile services (operators, content producers, etc.) 4) Maritime communications and navigation –communication (VHF, UHF & satellite) –navigation (satellite)

DIMETIC, Maastricht 9/10-07_BD4 Disruptive Technology S-curves for the established and disruptive technologies

DIMETIC, Maastricht 9/10-07_BD5 Technological life cycles The technological life cycles of the mobile communication industry

DIMETIC, Maastricht 9/10-07_BD6 Wireless history – the origins University research s: Maxwell, Hertz, Branley, Lodge, Popoff.. Commercial application: Wireless Telegraph Company founded by Marconi 1897 Wireless transmission across the Atlantic 1901 by Marconi One dominant group of customers: the navies

DIMETIC, Maastricht 9/10-07_BD7 Wireless history – public broadcasting Consumer radio based on radio valves or tubes took off from the early 1920s RCA founded 1919 General Electric (Edison) and Westinghouse the major equipment producers Europe: Philips, Telefunken, AEG, Siemens

DIMETIC, Maastricht 9/10-07_BD8 Wireless history – 0G (’landmobile’) Major boost during WW2 Boost of non-military applications after WW2 The commercial fleets: maritime radiocommunications ’Landmobile’: police, firefighters, transport companies (truck fleets, taxis etc.) Major companies in landmobile: General Electric, Motorola (founded in Chicago with the emergence of wireless technologies – the Galvin family) Danish Storno (founded 1947): No. 3 producer of equipment world wide in the 1960/70s.

DIMETIC, Maastricht 9/10-07_BD9 Wireless history – 1G a US invention, but… AT&T introduces first mobile telephony system in 1946 in St. Louis. Bell Labs scientist Ring invents the concept of cellular systems in AT&T, RCA and Motorola file proposals to use 800 MHz band for cellular systems 1983 FCC grants first commercial cellular licenses 1983 Ameritech launched first commercial cellular system in Chicago.

DIMETIC, Maastricht 9/10-07_BD10 Wireless history – 1G the Nordic market became the ’lead user’ NMT standardization began in 1970 among the Nordic PTO. NMT 450 MHz implemented in Sweden October 1980 and in Denmark, Finland and Norway in early However, first implementation actually in Saudi Arabia August 1980.

DIMETIC, Maastricht 9/10-07_BD11 Wireless history – 1G (analogue) the various standards NMT 450 and 900 from appr NMT introduced in 36 countries AMPS actually introduced in more countries than (e.g Latin America) But the penetration ratios in the Nordic countries significantly larger than anywhere else in the world. TACS in the UK and C-450 in West Germany

DIMETIC, Maastricht 9/10-07_BD12 Wireless history – 2G (digital) the various standards GSM from 1992: an EU effort. NMT ’copied’ - as an institution - and enlarged to the entire EU. ETSI formed in 1988 (took over from CEPT). GSM: the world winner. Operated in 103 countries in D-AMPS (Motorola and AT&T) and CDMA (Qualcomm) in the US. PDC in Japan.

DIMETIC, Maastricht 9/10-07_BD13 Wireless history – 2G a ’family’ of ETSI standards GSM 900 and GSM 1800 (called DCS 1800) DECT = cordless phones. Never a breakthrough in integration of GSM and DECT, although this will fulfill evident user needs. TETRA: a ’public, but closed’ system for police, firefighters, ambulances etc. ERMES: paging

DIMETIC, Maastricht 9/10-07_BD14 Wireless history – 2.5G GPRS: always on; makes WAP possible, higher transmission speed EDGE: makes transmission in the Kbit within reach GRPS and EDGE are ’extensions’ of the existing GSM networks EDGE is growing fast in the US GSM market

DIMETIC, Maastricht 9/10-07_BD15 Wireless history – 3G not a world standard IMT2000 a great ITU vision but did not succeed ETSI decision in January 1998 on W- CDMA = UMTS. The 3GPP group. CDMA2000 Qualcomm. 3GPP2. TD-SCDMA China? 3+ HSDPA
