BBI

The picture shows the BIM tablefor one test site, showing C/Imeasurements with SPC 181.This way we can show that theBBI is working.


The BIM is based on the DL signal levelmeasurements that the MSs have reported

for the serving and the neighbor DFCA cells.It is long-term statistical data that gives ageneral cell-level view on how the MSstypically experience the signal level ratiobetween the serving cell and a neighborcell.

The C/I Ratio means that if the source andthis interfering cell were to have the samefrequency allocated on the same timeslot,

then they the co-channel C/I would be theshown. The higher the C/I ratio in the table,the less is the potential for interferencebetween the two cells.
