Gi-Fi NEXT GENERATION WIRELESS TECHNOLOGY
[attachment=27275]
INTRODUCTION
Wi-Fi and WiMax have captured our attention.As there is no recent developments which transfer data at faster rate
as video information transfer taking lot of time.This leads to introduction of Gi-Fi technology
It offers some advantages over Wi-Fi, a similar wireless technology.In that it offers faster information rate(Gbps),less power consumption and low cost for short range transmissions.
WHAT IS Gi-Fi?
Gi-Fi is the world’s first transceiver integrated on a single chip that operates at 60GHz on the CMOS process.
It will allow wireless transfer of audio and video data at up to 5 gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth the cost.
Disadvantages of Bluetooth & Wi-Fi
The bit rates of Bluetooth is 800Kbps and Wi-Fi has 11Mbps.
Both are having power consumptions 5mw and 10mw .And lower frquency of opration 2.4GHz.
For transferring large amount of videos,audios,data files take hours of time in Bluetooth and Wi-Fi.
So to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology
ARCHITECTURE OF GI-FI:
The core components of a GI-FI system is the subscriber station which available to several access points.
It supports standard of IEEE 802.15.3C supports millimeter- wave wireless pan networks
The wireless pan is computer network used for communication among computer devices (including telephones and personal digital assistants) close to one person.
An 802.15.3c based system often uses small antenna at the subscriber station. The antenna is mounted on the roof. It supports line of sight operation.
FUNDAMENTAL TECHNOLOGIES IN 802.15.3C:
It transmits multiple signals simultaneously across the wireless transmission paths within separate frequencies to avoid interference.
ULTRA WIDE BAND FREQUENCY USAGE:
These features are Ultra-Wideband (UWB) is a technology for transmitting information spread over a large bandwidth (>500 MHz) that should, be able to share spectrum with other users.
It consists of
High bit rate
High security
Faster data transmission
FEATURES OF Gi-Fi:
High speed of data transfer:
Gi-Fi is data transfer rate is in Giga bits per second. Speed of Gi-Fi is 5 gbps.
which is 10 times the present data transfer. Hence we can swap large video, audio, data files with in seconds.
Low Power Consumption:
It consumes only 2 mwatt power for data transfer of gigabits of information.
where as in present technologies it takes 10 mwatt power. which is very high.
Small Size:
The chip, just 5 mm per side, has a tiny 1 mm antenna
It uses the 60 GHz ‘millimetre-wave’ spectrum
Other features:
It is also highly portable, high mobility.
It deployes line of sight operation having only shorter coverage area,it has more flexible architecture.
APPLICATIONS:
House hold appliances:
To watching movies,audios,videos without buffering in home theatre
To watching tv channels in HD quality
Office appliances:
As it transfers data at high speeds which made work very easy .its also provides high quality of information from internet .
Video information transfer:
By using present technologies video swapping takes hours of time ,where as by this we can transfer at a speed of gbps.
Advantages
High Security:
As the IEEE 802.15.3C provides more security.
it provides link level and service level security.
Cost-effective:
which is very less cost as compare to present systems.
As go on development the price will be decreased.
Disadvantages
The main disadvantages of the Gi-Fi is the it is work in short distance only and it is not work in long distance
CONCLUSION :
Within five years, we expect Gi-Fi to be the dominant technology for wireless networking.
By that time it will be fully mobile, as well as providing low- cost, high broadband access, with very high speed large files swapped with in seconds
