  3. 3. WHAT IS 4G? In telecommunications, 4G is the fourth generation of cellular wireless standards.  It is a successor to the 3G and 2G families of standards.  In 2009, the ITU-R organization specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards, setting peak speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users). 
  4. 4. DEFINITION OF 4-G TECHNOLOGY  4G is not one defined technology or standard, but rather a collection of technologies and protocols aimed at creating fully packet-switched networks optimized for data.
  5. 5. NEED FOR 4-G TECHNOLOGY Lower cost to user than current 3-G Technology.  Higher data rate than 3-G.  Service and application ubiquity  High degree of personalization and synchronization between various user appliances.  Higher capacity of network.  Smooth handoff across heterogeneous networks .  Seamless connectivity and global roaming across multiple networks.  Interoperability with existing wireless standards 
  6. 6. COMPARISON BETWEEN 3-G AND 4G Unlike the 3G networks which are a combination of circuit switched and packet switched networks, 4G will be based on packet switching only. This will allow low-latency data transmission.  Leading U.S. Carrier 3G EVDO network currently averages 400 to 700 Kbps with peak rates up to 2 Mbps. International Carrier is testing 4G communication at 100 Mbps while moving, and 1 Gbps while stationary 
