That was where the phones were found. Pellero determined that across the road in the park that there was a strong signal from the Wind cell antenna. Guess that's irrelevant ?
Here are tidbits from Dr. Pellero's testimony
"99 times out of a 100 the cell repeater 30064 would have been chosen as the repeater serving the points measured in Sant’Angelo Park, there exists a residual possibility in Meredith’s house that could be one, two or three per cent."
Question: It’s not possible to objectively say that the cell repeater 30064 is incompatible with via della Pergola, on the basis of these calculations which take into account the C2 factor, one can say that it is more likely that it was in Sant’Angelo Park, as a probability it’s about 99%?
Answer: Look the probability can be measured in these terms and what I can tell you is that at Sant’Angelo Park, the difference with the next nearest cell repeater is considerable, really considerable, so it would have used this repeater and wouldn’t have searched for another. This also because obviously I have taken into account the results of the measurements that were obtained by the Procura and this certainly permits me to exclude that the repeater 30064 was incompatible with via Sperandio, which emerged from the other side.
The best server cell towers at the cottage (Via Pergola 7) were Piazza Lupatelli GSM11107 and UMTS55201.
The best cell tower for Sant’Angelo Park where the stolen phones were recovered was wind cell 30064. It handled 99% of calls from Sant’Angelo Park and only handled 2 – 3% of calls from Via Pergola 7.
The tower which handled the 10:13 pm MMS message on the stolen phone was wind cell 30064.
