Just curious CI, are you sure this is a wireless device? Perhaps they are just in the process of getting it set up, and while it wouldn't cost a lot to get this one thing done, how many hundreds of these "one things" are involved in a project of this scale?
You asked earlier why the project is taking 4 years, but now you are wondering why they don't do a few things more than once?
It's like moving into a house, do you do the move first, then unpack? or do you unpack each box as it comes in so that you have access to your cheese grater the moment it comes into the house?
For me, I look at it like they closed down the area, and find other ways around. The fact that they are keeping it as open as they are is part of the reason it's taking so long. I'm sure if they shut it right down they could have it all done in 18 months.
