4G technology and its history, 1G, 2G, 3G

1. -Vipin Tejwani

2. 1G
 Based on Analog Telecommunication Standards.
 Started in 1980s in Europe & USA.
 Used Analog Radio signals.
 Range: 2.9KB/s to 5.6KB/s.
 First ever (cordless)phone to to
work on 1G network was
Motorola DynaTAC 8000X.

3. 2G
 Started in 1991 in Finland.
 Based on GSM (Global System for Mobile
Communications) Technology.
 Used Digital Radio signals and SIM(Subscriber Identity
Module) card.
 Range : 15kB/s to 40kB/s.

4. GSM Technology
 Global System for Mobile Communications (originally
it was called Groupe Spécial Mobile).
 Concurrent development started in USA and Europe
in the 1980’s.
 Developed by the European Telecommunications
Standards Institute (ETSI) in the early 1990’s

5. GSM Services
 Voice calls.
 Short Message Service (SMS)
- In 1985 GSM allowed messages of at most 160
characters to be sent between handsets.
- Only in USA over 6 billion
SMSs are sent everyday.

6. GSM Services…
 General Packet Radio Service (GPRS)
- Provided IP-based packet data transmission .
- Allowed users to “simultaneously” make calls and
send data.
- Provided “always on” Internet access and the
Multimedia Messaging Service (MMS).

7. 3G
 Based on Universal Mobile Telecommunications
System (UMTS).
 UMTS is an upgrade from GPRS with much more
bandwidth.
 Range of 3G(UMTS):
 144kB/s 384kB/s in rural.
 384kB/s to 27MB/s in urban.

8. 3G Services
 Mobile TV.
 Video Conferencing.
 Global Positioning System (GPS).

9. 4G
 Latest and Fastest Generation of mobile phone
communication.
 Based on same 3G Technology with improvements
named as LTE.
 First used in 2009 in Sweden.
 Range: 100MB/s to 1GB/s.

10. 4G (LTE)
 LTE stands for Long Term Evolution.
 Next Generation mobile broadband technology.
 Promises data transfer rates of 100 Mbps.
 Based on UMTS 3G technology.
 Optimized for All-IP traffic.
