Wireless local area networks defined by the IEEE 802.11 standards are very popular nowadays. Most of the smart phones, tablets, portable PCs have a radio unit for accessing these wireless networks. The required hardware is cheap, easily and widely available for mass production, the sufficient frequency bands (ISM) are open for unlicensed use for the public. Devices used in wireless networks (e.g. access points, repeaters, antennas, amplifiers) are widespread commercially. The standard is mature, the networking technologies and services built on top of it can be maintained reliably and cost-effectively.
The goal of my thesis is to build a system which can easily transmit an available Internet access to the subscribers through a wireless, dynamically scalable mesh network.
In my thesis I give a brief introduction to wireless networks, their pros and cons, and their possible applications in a mesh environment. I demonstrate a multi-node, simply and dynamically scalable network and it’s administrative interface. I also present the measurements I used to verify the correct behaviour of the network.
The implemented system described in this thesis can be easily and cost-effectively used to provide wireless Internet access to residential and office buildings, and other areas with higher number of clients (like outdoor events, concerts).
