The document discusses the evolution of wireless technologies from 1G to 5G. It describes the key features of each generation including 1G which enabled analog voice calls, 2G which provided text messaging, and 3G which allowed faster data speeds and smart phones. 5G is presented as the next major phase, promising speeds up to 10Gbps, lower latency, and the ability to connect many more devices simultaneously. Both advantages like high connectivity and disadvantages like high infrastructure costs are noted.

3. • The word wireless is dictionary defined “having no wires ”
. In networking terminology , wireless is the term used to
describe any computer network where there is no
physical wired connection between sender and receiver,
but rather the network is connected by radio waves and
or microwaves to maintain communications.
• Wireless networking utilizes specific equipment such as
NICs and Routers in place of wires .

4. • 1G refers to the first generation of wireless telephone
technology, mobile telecommunications which was first
introduced in 1980s and completed in early 1990
• It allows the voice calls in 1 country.
• 2G technology refers to the 2nd generation . It enables
services such as text messages, picture messages and
MMS.
• 2G network use digital signals.
• 2.5G is a technology between the second (2G) and third
(3G) generation of mobile telephony. 2.5G is sometimes
described as 2G Cellular Technology

7. o 2.5G Includes Phone Calls , Send/Receive E-mail
Messages, Web Browsing.
o 3G technology refer to third generation which was
introduced in year 2000s.Typically called Smart Phones.
o Providing Faster Communication , Send/Receive Large
Email Messages , High Speed Web / More Security
Video Conferencing / 3D Gaming , TV Streaming/ Mobile
TV/ Phone Calls.
o 4G technology refer to or short name of fourth
Generation. Faster & more reliable , Speed up to 100
Mbps , High performance , Easy roaming , Low cost..

10. ALL G’s ………

11. • 5G Wireless: 5th generation wireless technology .
• Complete wireless communication with almost no limitations .
• Can be called REAL wireless world.
• Has incredible transmission speed .
• Concept is only theory not real.
• It is highly supportable to WWWW (Wireless World Wide Web).
• 5G technology has changed the means to use cell phones within
very high bandwidth.
• User never experienced ever before such a high value technology.
Nowadays mobile users have much awareness of the cell phone
(mobile) technology. 5G technology most powerful and in huge
demand in near future.

13. • Next major phase of mobile telecommunication & wireless
system
• 10 times more capacity than others
• Expected speed up to 10 Gbps
• More faster & reliable than 4G
• Lower cost than previous generations
• Better & fast solution
• Most likely, will provide a huge
broadcasting data (in Gigabit),
which will support more than 60,000 connections.

14. Worldwide cellular phones.
Extraordinary data capabilities.
High connectivity .
More power & features in hand held phones.
Large phone memory, more dialing speed, more
clarity in audio & video .

16. Data BW of 10 Gbps or higher
Globally accessible
Dynamic information access
Available at low cost
Longer battery life.
Higher data rates.
More efficient.
Feasibility to connect 10 to 100 number of devices.
Worldwide coverage.
About 90% reduction in network energy usage.

17. Technology is still under process and research
on its viability is going on.
Developing infrastructure needs high cost.
Security and privacy issue yet to be solved.
• Technology is still under process and research
on its viability is going on.
• The speed, this technology is claiming seems
difficult to achieve (in future, it might be) because
of the incompetent technological support in most
parts of the world.

18. • Many of the old devices would not be competent
to 5G, hence, all of them need to be replaced
with new one — expensive deal.
• Developing infrastructure
needs high cost.
• Security and privacy
issue yet to be solved.
• It requires skilled engineers
to install and maintain
5G network.

19. • Business and Industry
• Schools , Colleges
• Doctors , Pilots
• Police and Vehicles etc

20. • 5G- User Centric
• We have proposed 5G wireless concept
designed as an open platform on different layers
• The new coming 5G technology will be available
in the market at affordable rates, high peak
future& much reliability than preceding
technologies.
• Create revolution in the communication era.
