Hi Pix
Thanks for your feedback and it meant a lot as i have been following your posts very seriously.But the question is we don’t know the culprit operator, see the site is a sharing site with multiple operators and the culprit could be one of them but it’s also in a very close periphery of other GSM sites which could easily interfere if they are using our frequnecy here in india we have multiple operators close to 10-11 GSM operators so the option suggested by you is really little vague.Till now our NPI team has been able to show the interference in those sites where KPI’s are really bad we have done everything from our sides, so this has been the solution for exclusion to be shown to our customer.Pls is there a way that we can catch its PLMN other than DT on its SIM.
