1-) Create a table [Filter_With] with only one field TXT_SUBSCRIBER_CELL_ID
2-) Populate this table with the TXT_SUBSCRIBER_CELL_ID's in the where clause.
3-) Join the Filter_With table with the TBL_TOWER_ANALYZER table.

4-) Define an index for the TXT_SUBSCRIBER_CELL_ID field in the TBL_TOWER_ANALYZER table.
5-) Define an index for the DAT_START field in the TBL_TOWER_ANALYZER.
