Range indicators for sectors in a wireless network may be determined by measuring, in a plurality of test locations, signal strengths of pilot signals transmitted by the sectors. Each sector's determined range indicator may be stored as a predefined range indicator for the sector in association with a list of predefined neighbors for the sector. When a candidate sector is added to a mobile station's active set, a neighbor list may be constructed for the mobile station, by taking into account the predefined range indicator for the candidate sector. If the predefined range indicator indicates that the candidate sector has a standard range, then the candidate sector's predefined neighbors may be added to the neighbor list. If the predefined range indicator indicates that the candidate sector has a non-standard range (e.g., indicating a “boomer”), then the candidate sector's predefined neighbors may be omitted from the neighbor list.
