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. A short history of wireless communications: networks & phones 1924? There is one version of this picture that attributes it to Bell Labs. 1983. Analog Motorola DynaTAC 8000X 1992. Nokia 1010. First mass produced GSM phone. 2002 Sanyo SCP- 5300. First Camera Phone (note – first clam shell phone around 1994 from Moto) 2003 – First RIM Bberry. Keyboard, email, enterprise. Take history as being ~~ correct; not completely sure, not expert. 2007. First iPhone is 2.5G 2008 First Android phone

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’ Stay Turned – Patent Wars in Process ? May always be a market for feature phones (Symbian)? Symbian *GSM featurephone) Nokia + (Sony/Samsung/etc.) => Accenture (2011).. Brew (CDMA featuephone) Qualcom, used by CDMA ODMS (all). 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 JavaME. Seems to completely loose out to Android. 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 ?? Apple iOS. iPhone rules profitability. Does Apple make it work this time? Harvest. Shrinking market share. - Loosing. - Will RIM strategies work? - Will Microsoft/Nokia work ? - Apple seems like the winner (profit), but …? - Android will win (market share.) - Are the ODMs spooked. - What about patent wars? Loosers. Doesn’t look recoverable.
