How does the Luz pie cut up on the telephone data?
There were 3 mobile operators in Luz in May 2007 – Optimus, TMN and Vodaphone. Other companies may have been working as virtual operators – those who supplied a service but did it by simply renting bandwidth from one of the three key players.
So, I want to focus on the big 3 and what is available from the information on the table.
Heriberto has detailed the latitude and longitude of the masts in Luz, and the direction of each main beam from the antennae.
I have cut up Luz based on a simple assumption. If a mast has 2 lobes, one pointing west and one pointing east, then there will be a boundary between these two. That border will split the zones covered by the lobes.
On the following graphic, apartment 5A is the pink dot. The lines are the boundaries between lobes for each mast.
The green lines are the areas covered by the Optimus mast, located on the Luz water tower. It has 3 (unequal) segments. It is poor for analysing movement within Luz as one lobe covers the bulk of the town.
The yellow lines are the TMN mast. It is on the top of 2 Rua Primeiro de Maio. This has 2 lobes, pointing east-west, so the boundary is basically north-south. The boundary is somewhere around block 5, but the graphic is not meant to be 100% accurate. It gives the basic idea, but there must be a wobble factor.
The red lines are the Vodaphone mast boundaries. Heriberto puts the mast slightly elsewhere, but I think it is also on top of 2 Rua Primeiro de Maio. It is 2 part, and slightly angled to the TMN mast.
It cuts the Luz pie into block 5 plus Tapas 9 to the east, with the Dolphin, Kelly’s and Smithman to the west.
I don’t know what is in the Scotland Yard data, so I don’t know how detailed they can delve.
But I wonder if this gives me enough to hunt down the Scandal at Chaplins? Is this a game changer?
