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

Technology Max Data Rate( in stationary)

2GGPRS,EDGE

up to 470 kbps

3GHSDPA, HSPA+

up to 30 Mbps

4GLTE

up to 1000 Mbps.

5G in near futureStandard not finalized

up to 7.2 Gbps, tested by Samsung last year

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

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.

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

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.
