Abstract

802.11 Wi-Fi technology is commonly used for creating wireless
access networks with a maximum range of one hundred meters. With careful
planning and proper antennas, this same technology can also be used to make
point to point links up to several kilometres. Since, it is not always feasible
and wise to run cables over long distances to connect different networks,
therefore, wireless links may turn out to be cost effective alternative to
their counterpart wired links while creating long distance networks
and providing network
scalability. Wi-Fi-based
point to point links can therefore be used to connect two local area network
(LAN) segments, which besides being cost-effective, provides network
scalability and other advantages such as high speed, centralized and easier
management and high throughput for line of sight (LOS) applications. A
Wi-Fi-based point to point link can extend the range of wireless LAN by a few
hundred feet to few miles which can further be increased by using highly directional
antennas for point to point links, while serving as a backup network in
different organizations. So, we have designed a soft private branch exchange
(PBX) system for a university campus or organization, facilitating voice over
internet protocol (VoIP) calls and
instant messaging, employing the idea of Wi-Fi- based point to point links. Moreover, we have also analysed the
quality of service (QOS) of the given setup in terms of data rate and
connectivity using bandwidth test and ping test respectively, for both
transmission control protocol (TCP) and user datagram protocol (UDP) scenarios.
