Corporate customers tend to have an account manager they can escalate to so
they can then call in favours in the mobile NOC to at least indicate the
servicing cell plus panel and rssi.
Then a directional antenna plus sdr having a poke around 900 or whatever
Vodafone are running their 2g on these days.
Then it's a case of making sure the box is generating some noise as if it's
just attached then the pings are very infrequent. Getting it to make a
voice or data session for a period of time is what you'll really need while
you triangulate it.

I would guess that the NZ Police would know the answer to this, they must need to track cell phones as part of their job.
Perhaps you could report the buoy as missing, maybe mention that it is marking something valuable dropped at sea, they may be able to locate it for you.

Hi everyone.
I am posting here as a last resort and this isn't really relevant to to this group, but more than anything I am hoping someone here may have some more knowledge about cellular technology than me. I have a customer that has lost a fairly expensive Buoy off the cost of Otago and it's GPS has stopped working. Vodafone have confirmed they are still seeing it connected to their cell tower (2G only) but the Vodafone helpdesk people aren't particularly helpful when we start asking them about options for finding a rough location at sea so we have an idea where to look for it.
Does anyone know if it's possible to triangulate a location of a cellular device these days? Is there a cutoff distance from the tower that the device will no longer be able to connect (e.g. if there is this helps narrow the search area at least)? Does anyone have an contact details for someone at VF that might be able to help?
If anyone has any info that might help, please contact me off list.
Thanks in advance.
