Features of Skype
1. peer to peer, no server required, therefore, no operation cost like cellular communications
2. overlay, not relying on existing Internet protocols beyond Layer 4, resilient to malfunctions of Internet services
3. scalable, using supernodes among every 500 nodes, adaptive to constant configuration changes
4. high quality codec for crystal voice
5. strong penetration to NAT and firewalls
6. free for now and maybe forever for on-net calls
7. implementation of packet voice
8. consumes reasonable bandwidth, consumes significant CPU
9 . teleconference, voice communications for 5 parties at most
10. millions people online all the times, number keep rising.
11. provide presence like messengers, great feature compared to old phones

mobile Internet
cellular handsets:
PHY: All digital
Signaling:
SMS, Short Message Service, up to 160 bytes
SMS, EMS use control channels while MMS use regular channels shared by data and voice.
Media Access: TDMA for multiplexing, using one of 8 time slots repeatedly
GSM, Circuit Switching, 9.6 (*2), 12.4(*2, HSCSD)
GPRS, General Packet Radio Services, Packet Switching, 9.05 kbps/13.4 kbps (*1,2,3,4)
WAP, content bearer protocol, certificate, cookies
WML, wireless markup language (or HTML-C as in i-Mode, XHTML)
MMS, Multimedia Messaging Service
Tariff
GPRS vs. GSM
pricing based on data volume or air time
Business Issues:
Will MMS make a hit?-
Function Integration

Recorder-TV,
British Royal Navy Sea Harrier (http://www.targetlock.org.uk/seaharrier/)
Format convergence products
2. DVD-Combo, DVD/VCD/CD
3. Card Reader, SD/SMC/MMC/CF
Advanced Applications
Positioning, LBS, GPS required for high precision
Security features
WIM: A Wireless Identity Module (WIM) can contain
both trusted and client certificates, private keys
and algorithms needed for WTLS handshaking,
encryption/decryption and signature generation.
The WIM module can be placed on a SIM card
and is then referred to as a SWIM card.
Social Issues:
base stations in communities
Near Fields
3G Technology Trends
Spread Spectrum: CDMA vs. TDMA (so called 3G)
MMS business issues
1. archiecture of MMS delivery systems
2. comparison to Internet
Principles of SS
1. from FDMA, TDMA to CDMA
2. related applications: IS-95, W-CDMA, 802.11
authentication and billing of wlan with SIM card
1. authentication
2. billing
3. coverage of both 802.11 & GPRS/3G
4. roaming across APs and WISPs
5. user base
