Cellular Wireless Communication History
CELLULAR WIRELESS COMMUNICATION STARTED IN AUTOMOTIVE 1G 1950s: analogue voice (NMT, AMPS, German A-/B-/C-Netz) 2G 1990s: narrow band digital voice (2.5G added packet data) 3G 2000s: broadband (WCDMA) integrated digital voice and data 4G 2010s: broadband (OFDM) digital data, all IP, multi RAN Tech 4 COPYRIGHT 2012 ALCATEL-LUCENT.

(Wireless) IP Expertise & Experience 70 W-CDMA commercial deployment 9+ LTE contracts and 60+ trials #2 in deployed LTE #1 in DSL - > 215 M lines shipped #1 in GPON Ericsson and Alcatel-Lucent Continue to Lead in LTE Redwood City, Calif. November 17, 2011 A recently published report by Dell Oro Group, the trusted source for market information about the networking and telecommunications industries, indicates that strong momentum in the mobile infrastructure market continued in 3Q11, as mobile RAN revenues increased 20% versus the year-ago quarter. The increase was driven in large part by sales of LTE and WCDMA, which comprised approximately one-half and one-third respectively of the total market s gain. The report also reveals that from 2Q11 to 3Q11, Ericsson and Alcatel- Lucent maintained their top ranks in LTE while increasing their shares to 44% and 30% respectively. 6 COPYRIGHT 20112ALCATEL-LUCENT.

KNOWN CURES FOR IMPROVING THE USER EXPERIENCE Introduce 4G / LTE Technology This will raise the amount of network capacity and improve the user experience (similar to improvements made in wired networks of DSL or cable data) The downside: It requires more equipment, usually in another band (which can have worse loss characteristics) Move the antennas closer to the user to decrease over-the-air loss An important side effect is improved network capacity The downside: It requires even more equipment (more transmitter / receiver combinations; small cell sites) The Industry Goal is to Become Less-Obtrusive while using Less Power 21 COPYRIGHT 2012 ALCATEL-LUCENT.
