By the end of this talk, You should be able to:
– Understand what 3G is all about.
– Understand the key terms and critical concepts of 3G technology
“Connecting you always”
3 Essential Terminology
• 3G – Third Generation • CDMA – Code Division Multiple Access • EDGE – Enhanced Data Rate for GSM Evolution

• First generation mobile telephony service
– Analog service: first commercial mobile phone service>ATUR 450 (automatic telephone using radio)
– based on NMT 450 (Nordic Mobile Telephone), voice only
– late eighties, ART 900 analog also based on ETACS (Enhanced Total Access Comm System)
– Mobifon800 based on AMPS (Advanced Mobile Phone Service)
– limited voice service

• Second generation mobile telephony service
– analog to digital communications with the intro of GSM early 90's
– cater for voice and data service at a rate of 9.6kbps
– DAMPS (Digital AMPS) also introduced same time

2.5G – Due to demand, packet switched technology introduced GPRS (General Packet Radio Service)
– improved rate of 115kbps
– MMS and SMS service enabled with GPRS
Today, Internet is pervasive, hence the need for access anytime anywhere – This leads to mobile internet and the most pervasive device to capitalize this is the mobile/cellular phone.
– Hence the introduction of 3G

• 3G is an ITU specification for the third generation of mobile communications technology.
– 3G promises increased bandwidth, up to 384 Kbps when a device is stationary or moving at pedestrian speed, 128 Kbps in a car, and 2 Mbps in fixed applications.
– 3G will work over wireless air interfaces such as GSM, TDMA, and CDMA.
– The new EDGE air interface has been developed specifically to meet the bandwidth needs of 3G.

• 3G technologies are an answer to the International Telecommunications Union's IMT-2000 specification. • Originally, 3G was supposed to be a single, unified, worldwide standard, but in practice, the 3G world has been split into four camps.

14 33GG ssttaannddaarrddss –– UUMMTTSS ((WW--CCDDMMAA))
• UMTS (Universal Mobile Telephone System), based on W-CDMA technology, is the solution generally preferred by countries that use GSM. – UMTS is managed by the 3GPP organization also responsible for GSM, GPRS and EDGE. • UMTS supports up to 1920 kbit/s data transfer rates
• FOMA, launched by Japan's NTT DoCoMo in 2001, is generally regarded as the world's first commercial 3G service. • It is compatible with UMTS

16 33GG ssttaannddaarrddss -- CCDDMMAA 22000000
• A significant 3G standard – an outgrowth of the earlier 2G CDMA standard IS-95. – primary proponents are outside the GSM zone in the Americas, Japan and Korea. • CDMA 2000 offers data rates of 144 kbit/s to over 3 Mbit/s. • The most successful introduction of CDMA-2000 3G networks is Japan's KDDI, which under the AU brand has more than 20 million 3G subscribers. – KDDI has upgraded the CDMA2000-1x network to CDMA2000-1xEV-DO which achieves data rates up to 2.4 Mbit/s. – In 2006, AU plans to upgrade the network to above 3 Mbit/s.

17 33GG ssttaannddaarrddss -- TTDD--SSCCDDMMAA
• A less well known standard is TD-SCDMA which is being developed in the People's Republic of China by the companies Datang and Siemens.
• They are predicting an operational system for 2005.

18 33GG ssttaannddaarrddss -- WWiiddeebbaanndd--CCDDMMAA
• Supports speeds between 384 kbit/s and 2 Mbit/s.
• When this protocol is used in a WAN, the top speed is 384 kbit/s.
• When it is used in a LAN, the top speed is 2 Mbit/s.
• Also adopted by the ITU.
