Wireless Electronic Notice Board
[attachment=66390]
Abstract
Notice Boards are a common occurrence in
variety of institutions which we come across on a
daily basis. In the current scenario the notice/
advertisement boards are being managed manually.
There is a long process involved in order to put up notices
on the notice board. This wastes a lot of resources like
paper, printer ink, man power and also brings about loss
of time. In this paper we have proposed a system which
will enable people to wirelessly transmit notices on a
notice board using Zigbee. In this paper we have
proposed a system by which only authorized people can
access the notice board using a graphical user interface.
We can also make the system compatible with more
than one wireless technology.
INTRODUCTION
Wireless technology has been making tremendous
progress over the past few years. The ever increasing
use of wireless networks serves as an indicator of the
progress in the area of wireless networks. The demand
for wireless technology is increasing not only in
industrial applications but also for domestic purposes.
Some benefits of wireless technology are:
• Completes the access technology portfolio:
customers commonly use more than one access
technology to ser- vice various parts of their
network and during the migration phase of their
networks, when upgrading occurs on a scheduled
basis. Wireless enables a fully comprehensive
access technology portfolio to work with existing
dial, cable, and DSL technologies.
• Goes where cable and fiber cannot: the inherent
nature of wireless is that it doesn’t require wires or
lines to accommodate the data/voice/video pipeline.
As such, the system will carry information across
geographical areas that are prohibitive in terms of
distance, cost, access, or time. It also sidesteps the
numerous issues of ILEC colocation
COMPARATIVE STUDY
Table I below summarizes [4] [1] the key
differences between the three short-range wireless
technologies. As shown below, Wi-Fi provides higher
data rates for multimedia access as compared to both
ZigBee and Bluetooth which provides lower data
transfer rates. ZigBee and Bluetooth are intended for
WPAN communication (about 10m), while Wi-Fi is
de- signed for WLAN (about 100m). Although
certain ZigBee chipsets can reach a range of upto
100
ZIGBEE PROTOCOL
ZigBee is a specification for a suite of high level
communication protocols using small, low-power
digital radios based on an IEEE 802 standard for
personal area networks. [5] ZigBee devices are often
used in mesh network form to transmit data over
longer distances, passing data through intermediate
devices to reach more distant ones. This allows ZigBee
networks to be formed ad-hoc, with no centralized
control or high-power transmitter/receiver able to reach
all of the devices. Any ZigBee device can be tasked with
running the network.
FUTURE SCOPE
Electronic Notice Board is one of the application
where Zigbee can be used effectively. It can also be
used in Malls and Highways for Advertisement purpose.
A moving display with variable speed can also be used
in place of static display
