  1. A Short History of the World Wireless Communications "I took the speed reading course and read 'War and Peace' in twenty minutes. It's about Russia."  - Woody Allen

  2. 2007. First iPhone is2.5G A short history of wireless communications: networks & phones 2002 Sanyo SCP-5300.

First mass produced GSM phone. 2008 First Android phone Take history as being ~~ correct;not completely sure, not expert.

  3. Example: Inbound Call (2G/3G)

  4. Adding broadband (3G) data • PDSN (looks like an aggregation router for DSL): • Terminates the PPP session, provides NAT (some carriers). • Provides AAA (accounting, authorization, authentication) • DHCP. • Why PPP (point to point protocol – layer 2 protocol)? Auth, encryption, compression.

  5. Mobile Phone O/S’ Harvest. Shrinking market share. • Brew (CDMA featuephone) • Qualcom, used by CDMA ODMS (all). • Symbian *GSM featurephone) • Nokia + (Sony/Samsung/etc.) => Accenture (2011).. - Loosing. - Will RIM strategies work? - Will Microsoft/Nokia work ? • RIM (Blackberry O/S), ends with O/S 7. • RIM purchase QNX (emb R/T Unix)=> O/S . • Purchases Ubitexx to enable BES backend for services on iPhone and Android (2011) • Microsoft: Windows Mobile, Windows 7, Windows 8, ……. • Alliance with Nokia - Apple seems like the winner (profit), but …? - Android will win (market share.) - Are the ODMs spooked. - What about patent wars? • Apple iOS. • iPhone rules profitability. • Does Apple make it work this time? • Android: Linux/JavaME for embedded. • Google writes it’s own byte code interpreter to get around SUN/Oracle. Oracle sues. • Palm O/S => Web O/S • HP purchases Palm then kills Web O/S ?? • JavaME. Seems to completely loose out to Android. Loosers. Doesn’t look recoverable. • Stay Turned – Patent Wars in Process ? • May always be a market for feature phones (Symbian)?
