2. WHAT IS BROADBAND????
• 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.

3. 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.

4. 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 microprocessor
 Analog signal.

5. 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

6. 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

9. 4G STANDARDS
• 4G is set with mobile Wimax std and LTE std.
• LTE technology is the new radio interface that uses wide radio channels
and delivers extremely high throughput rate.
• Wimax stands for worldwide interoperability for microwave access.
• Wimax is IP based wireless broadband access technology
• Wimax is a wireless digital communication system, also known as IEEE
802.16.

11. 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.

12. 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.
