Abstract [en]

This thesis investigates the IEEE 802.11b standard that describes radio communication for networks. The standard is carefully explained and the limitations of the standard are presented. To put the system in its context and to study the effects from the frequency translation, surrounding areas such as radio propagation and networks in general are presented. For radio communications the carrier frequency gives the basic properties for the application, long distance communication uses low frequencies and the opposite for short-range communication. The report investigates the possibilities to translate the frequency for an IEEE 802.11b system to move the limits of IEEE 802.11b Three alternative solutions are compared. A final solution evolves from one of them. The resulting solution is based on existing hardware and is ready for testing. One major conclusion is that 802.11b is a well developed standard where the development of the hardware is focussed on the physical size. This miniaturization makes alteration more complex. Finally other interesting wireless techniques that could give the desired properties and other possible further work are presented.
