This presentation simply shows the evolution and future wireless high speed communication technologies.

1. Evolution of wireless network
Wide range communication Networks
• In 1980s 1G analog network
• In 1990s 2G first digital network
• Around 2001, 3G emerged
• 4G LTE introduced in 2011
from this decade long cycle 5G network are due
around 2021

2. Technology Max Data Rate
( in stationary)
2G
GPRS,EDGE
up to 470 kbps
3G
HSDPA, HSPA+
up to 30 Mbps
4G
LTE
up to 1000 Mbps.
5G in near future
Standard not finalized
up to 7.2 Gbps, tested by
Samsung last year

3. 5G
• This technology will commercially available from
2020.
• In 2013, global mobile connection grew to around
7 billion and proliferating rapidly.
• Arrival of smart phones and wearable devices lead
to Internet of Things, for which devices require
reliable and fast data connection

5. Research in 5G
• Government and many mobile and networking
companies invested several billion dollars for the
research and development of 5G technology across
the world
• As of now, Samsung electronics successfully conducted
test of 28 Ghz 5G network in both stationary (up to 7.5
Gbps) and in moving at over 100 km/h (up to 1.2
Gbps)
In both 4G and 5G MIMO antenna and optimized DSP
algorithms are used to enhance the speed of data.

6. Short range Wireless communication
Existing
Technology Range Data rate
Bluetooth
Version 4
up to 10 meters max 24 Mbps
Wireless Fidelity
802.11 b/g/n/ac
up to 100 meters up to 1000 Mbps
Zig Bee up to 100 m - LOS up to 256 kbps

7. New developing technologies (under development)
• Wi Gig is also a Wi Fi technology
• Li Fi uses Visible Light for data transfer – LED can be
used as a data router in this technology.
Technology Range ( tested) Data rate ( tested)
Wi Gig -802.11ad
60 GHz band
Up to 100 m Up to 7 Gbps
Light Fidelity - LiFi Short range ( 5 m) Up to 500 Mbps
