future wireless technologies - after 2020
TRANSCRIPT
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.
Technology Range ( tested) Data rate ( tested)
Wi Gig -802.11ad60 GHz band
Up to 100 m Up to 7 Gbps
Light Fidelity - LiFi Short range ( 5 m) Up to 500 Mbps
