DN question in 3G Drive Test

Tg Yaw Isaac (Ghana):
Hello team, please I conducted a drive test on 3G and the planning engineer made the below comment:
“DN is HSDPA KPI plot in Y sector need to be defined.”

Can any one explain to me what it means?
Does it have anything to do from field.

Tg Adeel Ahmed (Pakistan):
Some nbr relation is missing and it showing as DN ( Detected neighbor) which need to be define… ask planning team if you know exact cell id of detected nbr

Tg Yaw Isaac (Ghana):
Thanks Ahmed

Tg Kayode S. Banjo (Nigeria):
They are detected neighbor n need to reaffirm their location before adding them is important
