Comparative Analysis of Wireless Technology Generations: 1G to 4G

This report provides an overview of the evolution of wireless technology, from 1G to 4G, including the different generations and their key features. It starts with 1G technology, which uses FDMA and provides a speed of 2.4 to 14.4 Kbps. It then moves to 2G, which introduced text and picture messages, and 3G, which supports high-speed data up to 3.5 Mbps and allows live streaming. Finally, the report discusses 4G technology, which supports speeds up to 100 Mbps and is suitable for streaming HD videos. The report also analyzes the advantages of 3G and 4G for businesses and employees, including the use of smartphones with minimum features, portability, and low upgrade and maintenance fees. The report also highlights the disadvantages, such as security issues and the need for hardware investments. References are provided for further reading.

Advantages of Wireless Medium

 This technology refers to
the 1st generation
wireless technology.
 This technology uses
FDMA (Frequency
division multiple
access).
 Speed is around 2.4 to
14.4 Kbps.
History- 1G

 MMS, text and picture
messages were the fruits
of 2G technology.
 Inefficiency exists on how
bandwidth is used.
 Phones do not support
high speed.
 It offers maximum speed
of 40 Kbps.
History- 2G

 Smart phones were introduced
in this era.
 There is significant increase in
bandwidth when compared to
2G.
 Enables live streaming
(Agrqwal et al., 2015).
 An average speed of 3.5 Mbps
is supported by 3G networks.
History- 3G

 Supports high speed data.
 It supports maximum speed
up to 100mbps.
 HD videos can be streamed
without a hitch (Kumar &
Iqbal, 2015).
 A normal length movie can
downloaded in matter of
minutes.
History-4G

 Telestra employees should prefer either
3G or 4G networks.
 3G would cost less however the data
speed provided in 4g networks offers
much greater benefits.
 Most digital devices are 4G enabled.
Preferred network for employees

 The resolution size is 720 by 1280
pixels.
 Display size is 4 to 5 inch.
 Ram is 1 to 2 GB.
 Will run on IOS and android operating
system.
 It will be useful for Telestra employees
as a smart phone with minimum
features will be able to run all the apps.
Minimum features of 4G phone

 Employee of the company will
always remain connected.
 At once several devices can
be connected ("The
Advantages of Using Wi-Fi on
Your Smartphone", 2018).
 Portable devices such as
phones and tablets should be
used.
Wi-Fi benefits

 Upgrade fees and also
maintenance fees are low.
 The main requirement for the
company is to contact a service
provider who provides high
speed broadband.

 Users need to be aware of
attacks such as DoS attacks,
phishing, malware attacks,
virus attacks and man in the
middle attacks.
 Security framework needs to
be established to prevent
attacks.
Wi-Fi security issue

 Portability issues will
be there since
desktops and laptops
are bulky in nature.
 The company has to
pump in more
investment due to
hardware
requirements.
Issues in portability

 There would not be any
issues since a handheld
device can perform
nearly the same
function as desktop.
 Upgrade fees are there
and this can be
eliminated if the
company goes for
portable devices.
