Assessment of the CIR in BWA networks using switched beam antennas

The results are envisaged to be utilised in next generation smart antennas for mobile broadband systems. One of the reasons of the deployment of 3G smart antennas (UMTS CDMA) is the improvement of co-channel interference. Future broadband-smart antennas shall reuse the results, hereby described.

The Space Division Multiple Access (SDMA) realised by smart antennas for broadband access shall have the additional advantage to reduce the EME whose impacts on the environment may be higher at these frequency bands (tens of GHz).

This result shows how employing switched beam antennas the carrier-to-interference ratio, which limits the number of active users and coverage of a given BS, can be increased. It also shows how the number of elements influences the obtained CIR. Design rules are provided to optimise the complexity to performance ratio.
