A method of improving a location estimate of transceivers co-located at a sectored cell site, the method comprising: identifying a plurality of transceivers (402a, 402b, 402c) that are co-located at the sectored cell site, wherein identifying the plurality of transceivers that are co-located comprises: accessing location information of a plurality of transceivers from a data store of a plurality of unique transceiver identifiers (IDs) and associated respective location estimates; grouping the plurality of transceiver IDs together into possible co-location groups based on the location estimates so that transceiver IDs associated with respective location estimates within a distance threshold of each other are grouped together; and for each possible co-located group: determining if the plurality of transceiver IDs of the plurality of transceivers in the possible co-located group are consistent with a co-location sector scheme used in labelling unique transceiver IDs of sectored cell sites; and identifying each of the plurality of transceiver IDs with consistent transceiver IDs as co-located transceivers; determining a location of a virtual transceiver as an average of respective location estimates (408a, 408b, 408c) of the plurality of identified transceivers; and assigning the determined location of the virtual transceiver to each of the transceivers (402a, 402b, 402c) determined to be co-located. identifying a plurality of transceivers (402a, 402b, 402c) that are co-located at the sectored cell site, wherein identifying the plurality of transceivers that are co-located comprises: accessing location information of a plurality of transceivers from a data store of a plurality of unique transceiver identifiers (IDs) and associated respective location estimates; grouping the plurality of transceiver IDs together into possible co-location groups based on the location estimates so that transceiver IDs associated with respective location estimates within a distance threshold of each other are grouped together; and for each possible co-located group: determining if the plurality of transceiver IDs of the plurality of transceivers in the possible co-located group are consistent with a co-location sector scheme used in labelling unique transceiver IDs of sectored cell sites; and identifying each of the plurality of transceiver IDs with consistent transceiver IDs as co-located transceivers; determining a location of a virtual transceiver as an average of respective location estimates (408a, 408b, 408c) of the plurality of identified transceivers; and assigning the determined location of the virtual transceiver to each of the transceivers (402a, 402b, 402c) determined to be co-located. accessing location information of a plurality of transceivers from a data store of a plurality of unique transceiver identifiers (IDs) and associated respective location estimates; grouping the plurality of transceiver IDs together into possible co-location groups based on the location estimates so that transceiver IDs associated with respective location estimates within a distance threshold of each other are grouped together; and for each possible co-located group: determining if the plurality of transceiver IDs of the plurality of transceivers in the possible co-located group are consistent with a co-location sector scheme used in labelling unique transceiver IDs of sectored cell sites; and identifying each of the plurality of transceiver IDs with consistent transceiver IDs as co-located transceivers; determining a location of a virtual transceiver as an average of respective location estimates (408a, 408b, 408c) of the plurality of identified transceivers; and assigning the determined location of the virtual transceiver to each of the transceivers (402a, 402b, 402c) determined to be co-located. determining if the plurality of transceiver IDs of the plurality of transceivers in the possible co-located group are consistent with a co-location sector scheme used in labelling unique transceiver IDs of sectored cell sites; and identifying each of the plurality of transceiver IDs with consistent transceiver IDs as co-located transceivers; determining a location of a virtual transceiver as an average of respective location estimates (408a, 408b, 408c) of the plurality of identified transceivers; and assigning the determined location of the virtual transceiver to each of the transceivers (402a, 402b, 402c) determined to be co-located.
