Abstract
Abstract A cost effective electronically self optimizing antenna system is provided for use with each subscriber unit in both fixed and mobile wireless applications. The smart antenna consists of multiple antenna elements arranged so that individual beams independently cover sections of free space. Collectively, complete coverage of the desired free space is accomplished. The smart antenna uses a relatively narrow beam directed in the appropriate direction thereby reducing interference and improving system capacity. A controller is included which continuously monitors the signal quality and intelligently selects the optimum antenna beam pattern configuration. All telecommunication protocols, both analog and digital, can be accommodated by the controller.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
A method for determining the optimal configuration of a directional antenna system allowing access between a fixed or mobile subscriber location and a wireless radio frequency communications system having multiple base stations, where said method comprises the following steps: for each of a plurality of antenna configurations, receiving the radio frequency signal through said antenna system; measuring the signal to noise ratio resulting from each of said antenna configurations; prioritizing the signal to noise ratios of said antenna configurations; selecting a default antenna configuration from prioritized said antenna configurations; monitoring the signal to noise ratio of selected said default antenna configuration; monitoring signal to noise ratios of all said antenna configurations; switching to another antenna configuration if the signal to noise ratio produced by said selected default antenna configuration fails to satisfy a predetermined criterion.
Claim 2
Independent Claim
135 words
A method for determining the optimal configuration of a directional antenna system allowing access between a fixed or mobile subscriber location and a wireless radio frequency communications system having multiple base stations, where said method comprises the following steps: for each of a plurality of antenna configurations, receiving the radio frequency signal through said antenna system; measuring the signal to noise ratio resulting from each of said antenna configurations; prioritizing the signal to noise ratios of said antenna configurations; selecting a default antenna configuration from prioritized said antenna configurations; monitoring the signal to noise ratio of selected said default antenna configuration; monitoring signal to noise ratios of all said antenna configurations; switching to another antenna configuration if the signal to noise ratio produced by said selected default antenna configuration fails to satisfy a predetermined criterion.
Claim 3
Dependent Claim
28 words
A method for determining the optimal configuration of a directional antenna system as recited in claim 1 where said predetermined criteria is a preset signal to noise ratio.
Claim 4
Dependent Claim
28 words
A method for determining the optimal configuration of a directional antenna system as recited in claim 1 where said predetermined criteria is a relative signal to noise ratio.
Claim 5
Independent Claim
130 words
A method for determining the optimal configuration of a directional antenna system allowing access between a fixed or mobile subscriber location and a wireless radio frequency communications system having multiple base stations, where said method comprises the following steps: for each of a plurality of antenna configurations, receiving the radio frequency signal through said antenna system; measuring the bit error rate resulting from each of said antenna configurations; prioritizing the bit error rates of said antenna configurations; selecting a default antenna configuration from prioritized said antenna configurations; monitoring the bit error rates of selected said default antenna configuration; monitoring bit error rates of all said antenna configurations; switching to another antenna configuration if the bit error rate produced by said selected default antenna configuration fails to satisfy a predetermined criterion.
Claim 6
Independent Claim
130 words
A method for determining the optimal configuration of a directional antenna system allowing access between a fixed or mobile subscriber location and a wireless radio frequency communications system having multiple base stations, where said method comprises the following steps: for each of a plurality of antenna configurations, receiving the radio frequency signal through said antenna system; measuring the bit error rate resulting from each of said antenna configurations; prioritizing the bit error rates of said antenna configurations; selecting a default antenna configuration from prioritized said antenna configurations; monitoring the bit error rates of selected said default antenna configuration; monitoring bit error rates of all said antenna configurations; switching to another antenna configuration if the bit error rate produced by said selected default antenna configuration fails to satisfy a predetermined criterion.
Claim 7
Dependent Claim
