Thursday I will be out most of the day… I am going everywhere. I have a meeting at North Ryde. Then I need to drop in at Civinex at Sydney Olympic Park before visiting Cebit at Darling Harbour. So I will be a busy boy. Not sure if I will have wireless access anywhere – I doubt it unfortunately. We will see.

I have been doing some product testing the tracker, on what happens if it looses cell phone coverage. Unfortunately, there are times here that the tracker does not need an antenna – so I have built what is called a ‘Faraday Shield’. It is what keeps the microwave signals inside your microwave oven, and is a way to make sure that signals cannot get in or out.

I have a photo of mine below. This is obviously only for testing, but it works. The phone in the tracker cannot contact a base station no matter what, which is exactly what I needed. And thankfully the software in the tracker is working outside cellphone coverage, and I can prove it now.
