Methods and systems of adjusting antenna electrical tilt

A system for automatic cellular antenna electrical tilt adjustment comprising:

• at least one cellular antenna arranged in at least one cluster as part of a cellular network;
• a computer in electrical communication with the at least one antenna, the computer programmed to receive signals from the at least one antenna and calculate at least one parameter indicative of mobile client resource use associated with the at least one cellular antenna;
• a hardware processor in electrical communication with the computer and with the at least one antenna;
• a non-transitory memory having stored thereon program modules for instruction execution by the hardware processor, comprising:
• a module for selecting a target coverage parameter for the at least one antenna according to the at least one parameter indicative of client resource use;
• calculating a coverage cost for the at least one antenna using an initial electrical tilt angle;
• iteratively adjusting an electrical tilt angle of the at least one cellular antenna so that the at least one parameter indicative of mobile client resource use is maintained within at least one predefined threshold, thereby providing users of the mobile clients of the at least one cellular antenna with at least a level of service within the at least one predefined threshold and wherein iteratively adjusting further comprises iteratively adjusting the electrical tilt angle according to the calculated coverage cost for the selected tilt angle relative to the target coverage cost parameter.

A computer program product for automatically selecting an electrical antenna tilt angle, the computer program product comprising:

• one or more non-transitory computer-readable storage mediums, and program instructions stored on at least one of the one or more storage mediums, the program instructions comprising:
• program instructions for automatically receiving at least one parameter indicative of client resource use for at least one antenna of a plurality of antennas arranged in at least one cluster as part of a cellular network;
• program instructions for automatically selecting a target coverage cost range for the at least one antenna according to the at least one parameter indicative of client resource use;
• program instructions for automatically calculating a coverage cost for the at least one antenna using an initial electrical tilt angle;
• program instructions for automatically calculating a corresponding interference cost of the at least one antenna using the initial electrical tilt angle;
• program instructions for automatically selecting an electrical tilt angle for the at least one antenna, by iteratively changing the initial tilt angle, so that the calculated coverage cost for the selected tilt angle is within the target coverage cost range, and so that the corresponding calculated interference cost for the selected electrical tilt angle is at a minimum within the target coverage cost range;
• and
• program instructions for automatically changing the existing electrical tilt angle of the at least one antenna according to the selected electrical tilt angle.
