picoCell/microCell/nanoCell Base stations are low powered GSM nodes designed for indoor or small area GSM coverage. Their transmission power is low enough to meet the legal restrictions of many countries.

Here are two examples;

http://www.ipaccess.com/ipaccess_pages2/bts2.html

Both of these Base Stations have an RJ-45 in order to do Ethernet on the
back end; GSM in, IP out.

I wonder if anyone has experience interfacing one of these or a similar
product with Asterisk?

I also wonder if Digium has any plans to supply PCI cards which provide
similar functionality?

The prospect of recycling old cell phones for use as Asterisk extensions
is extremely attractive.

Cellular phone ---GSM---> picoCell ---IP---> Asterisk

This looks interesting, but can you explain this a bit more? The term "IP out" is incredibly vague, and on neither of the websites (after a 30 second review) did they say exactly what they mean with "IP out". Does this turn GSM calls into SIP transactions? Does it need another similar device somewhere else on the IP network that then turns the calls back into TDM via an FXS interface? What _does_ IP mean in this context?
