Abstract

A method of adjusting an antenna beam pattern of an antenna array arrangement for a wireless communication network that combines the application of a smart antenna and a clever antenna is provided. The method dynamically controls the smart antenna to adjust the beam pattern to simultaneously compensate for inter-sector interference generated by the side lobes of the beam pattern and to correct the inter-sector interference created by the over extension of the elongated main lobe of the beam pattern. In order to reduce the inter-sector interference of the side lobes, the gain of the antenna is increased to elongate the main lobe. To offset the over extension of the main lobe, the smart antenna is adjusted to balance the soft handoff boundaries in response to the traffic load detected, and the soft handoff boundaries are stabilize to match the time constants of the soft handoff parameters.
