EVOLUTION FROM 1G TO 5G
WHAT IS WIRELESS?
The word wireless in dictionary is 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 communication.
Wireless networking utilize specific equipment such as NICs and
routers in places of wires (copper or optical fibers).
1G refers to the first generation of wireless telephone
technology, mobile telecommunication which was first
introduced in 1980 and completed in early 1990.
it’s speed was upto 2.kbps to 5.6kbps.
it allows the voice call in 1 country.
1G network use Analog signal.
AMPS(Advance mobile phone system) was first
launched in USA in 1G mobile system.
first ever (cordless)phone to work on 1G network was
Motorola dyna TAC8000x. frequency typically 150MHZ to
DRAWBACKS OF 1G
Poor voice quality.
Poor battery life.
Large phone size.
No security .
poor handoff Reliability.
2G technology refers to the 2nd generation which is based
on GSM .
it was launched in Finland in the year 1991.
2G network use digital signals.
it’s data speed was upto 64kbps.
it enables services such as txt messages ,pictures
messages and MMS(multi media message).
It provides better quality and capacity.
DRAWBACKS OF 2G
2G require strong digital signals to help mobile
phone work. If there is no network coverage in any
specific area ,digital signals would weak.
these systems are unable to handle complex data
such as videos.
3G Technology refer to third generation which
was introduced in year 2000s .
DATA transmission speed increased from 144kbps-
typically called smart phones and features
increased bandwidth and data transfer rates to
accommodate web-based application and audio and
Features of 3G Technology
Providing faster communication .
send /receive large email messages.
high speed web /more security. Video conferencing
TV streaming /mobile TV/phone calls.
Large capacities and broadband capabilities .
11 sec-1.5min.time to download a 3 min Mp3 songs
DRAWBACKS OF 3G
Expensive fees for 3G Licenses services
It was challenges to build the
infrastructure for 3G.
High bandwidth requirement.
Expensive 3G phones.
HIGH speed data access.
High quality streaming video.
Combination of Wi-Fi and Wi-max.
Capable of providing 100 mbps-1gbps.
4G should be able to provided very smooth global roaming with 4G PHONE
It offer both cellular and broadband multimedia services everywhere.
One of the basic term used to describes 4G Is MAGIC.
Mobile multimedia .
Global mobility support
Integrated wireless solution.
Customized personal services
also known as Mobile broadband Everywhere.
4G (Anytime ,Anywhere)
The next generation of wireless technology that promises higher
data rates and expanded multimedia services.
Capable to provide speed 100 mbps-1gbps.
High QOS and high security.
Provide any kind of services at any time as per user
More security .
High speed .
Low cost per-bit etc.
DRAWBACKS OF 4G
battery uses is more.
Hard to implement .
Need complicated hardware.
Expensive equipment required to
implement next generation network.

5G WIRELESS TECHNOLOGY
What is Huawei doing to make 5G a reality?
Like others in the networks industry, Huawei is vested in delivering a 5G network as
soon as possible. In November last year, the Chinese manufacturer partnered with
Russian carrier MegaFon to develop and build a prototype 5G network in time for
FIFA World Cup that takes place in Russia in Summer 2018. If developed in time, this
network is expected to be the first publicly launched 5G network and Huawei also
plans to also deliver the world’s first 5G phones in time for the 2018 World Cup.
Huawei firmly believes that 5G will deliver the possibilities of 1Gbps data speeds,
offer latency of less than 1 millisecond and support 100 billion connections as part of
an everything-connected world. The company says that 5G will offer the benefits to
mobile, Internet Of Things and Cloud services allowing data – both physically on your
handset and virtually in the cloud – to be accessed freely and instantly.
5G WIRELESS TECHNOLOGY
5G technology refer to short name of
fifth generation which was started from
Complete wireless communication
with almost no limitations.
It is highly supportable to wwww
(wireless world wide web).
BENEFITS OF 5G TECHNOLOGY
High speed, high capacity.
5G technology providing large
broadcasting of data in Gbps.
multi-media newspapers, watch TV
programs with the clarity as to that of an HD
faster data transmission that of the
BENEFITS OF 5G TECHNOLOGY
Large phone memory ,dialing speed,
clarity in audio/video.
support interactive multimedia, voice
Streaming video, internet and other .
5G is more effective and more attractive.

All totally the best way to help all users is to use 5G
as the next wireless system and in totally it is safety
and secure for public, this the need that demands the
Todays wired society is going wireless and if it has
problem,5g is solution of the problem.
5G technology is going to give tough competition to
computers and laptops.
It will be available in the market 2020 at affordable
cost with more reliability than previous mobiles.
