Gi-Fi will helps to push wireless communications to faster
drive. For many years cables ruled the world. Since the installation of these
optical fibers need much cost,caused a greater difficulty and thus led to wireless access. The first
and foremost one is Bluetooth which is used to cover 9-10 meters. Later on
WI-FI entered into field which can cover 91 meters. However the need for
increase in data rates are growing, so to meet the requirements we need another
way of transmission.
Gi-Fi is a wireless technology developed to work in a range
of 10m with transmission rates of gigabits per second. Gi-Fi is evolved since in
Bluetooth and WIFI transfer rates are 800kbps and 11mbps respectively, but for
Gi-Fi as the name specifies it is gigabits per second.
How it works???
In this we use
duplexer so that antenna can be used for
both transmission and reception purposes. During transmission, intended data
files are converted from IF signals into RF signals using two mixers. To
have high signal strength the converted RF signals are fed to power
amplifier at the transmission side. During reception, RF files are converted
to a range of normal data files. In receiver side, we use
heterodyne receiver construction to avoid leakage from direct conversion.
With Gi-Fi we can even reduce the power consumption from
10Watts(in Bluetooth and Wi-Fi) to 2Watts which is mainly essential. With the
GIFI we can access home appliances and internet radio modules. Gi-Fi is even highly secured as it follows IEEE 802.15.3C By considering
the success of Wi-Fi and Wimax. we can surely say that GIFI is able to play a key
role in next years.
