Multiple Cell Phones 1

[itsmoked]

Is there a way to have a large constellation of independant cell phones?

Example: You have a hundred sites that you want to gather information at certain times and email it in, but you don't want 100 monthly accounts. They could all have the same phone number. They would only call in.

What happens when someone inevitably, wrong number, dials that phone number?

What would happen if more then one phone emailed(called) in at the same same time.

Yes skalybur I know of them, but I didn't think there were commercial ones.

You didn't hear it from me, but you can have multiple cell phones with the same phone number, at least in the TDMA/GSM world. As long as only one is active at a time, all is well. If you sequenced the phones in time such that only one was powered up at one time, it might work. You can buy all the phones you need on eBay. But probably not practical for 100 phones.

Not sure of the geography of your application, but we've had good luck with the unlicensed broadband radio systems over fairly long distances and rough terrain. Might check

These have worked well for us for water and sewage pump station monitoring.
