• The term broadband refers to the wide bandwidth characteristics of a transmission medium and its ability to transport multiple signals and traffic types simultaneously. The medium can be coax, optical fiber, twisted pair or wireless.
1G 2G 3G 4G 4G is 4th generation of mobile phone communication std. 4G provide mobile ultra broadband internet access.
4G networks are projected to provide speeds of 100 Mbps while moving and 1 Gbps while stationary.
1G Technology
1G refers to the first-generation of wireless telephone technology was developed in 1970’s.
1G had two major improvements:the invention of the microprocessorAnalog signal.
2G Technology
Around 1980’s
Better quality & capacity - More people could use there phones at the same time
Digital Signals – consist of 0’s & 1’s
3G Technology
Large capacity and broadband capabilities
Allows the transmission of 384kbps for mobile systems and up to 2Mbps
Increased spectrum efficiency –5Mhz A greater number of users that can be simultaneously
supported by a radio frequency bandwidth High data rates at lower incremental cost than 2G–
Global roaming
Fourth Generation
Cost reduction

PROBLEMS WITH 4G
• Taking Time for the companies to make phones that are capable of that speeds .’
• Being able to access the Internet has an economic facet, as the cost of infrastructure, equipment, and services can determine the level of access available to regions, communities, and individuals.
RELIANCE PLANS TO LAUNCH 4G IN INDIA
• As per the latest reports, the company will first launch its 4G service in Jamnagar before launching it throughout the country.
• Apart from this, the company is also planning to set up 1,00,000 towers across all circles and to bring broadband plans for its 4G venture.
