All,

Does anyone know of any RF shielding solutions that provide battery power to keep the acquired mobile device powered?

There maybe situations where if the device looses power, it may not be possible to gain access to the device again due to encryption or difficult passcodes.

You might want to check this out http//www.teeltech.com/tt3/black-hole-forensic-bag.asp.

It has a built-in shielded USB port.

Call for quote always scares me.

Try this one Black Hole Data Bag Kit

I have this bag, and I have a warning. In an area of particularly strong signal, I've had a phone in this bag connect to the tower and download a couple SMS messages. I don't know if this would happen with any other bag–I suspect it would–so it's best to just use the bag long enough to put the device in airplane mode. If you can't do that, then test your bag repeatedly with different phones and networks before puting it in service in your lab.

The kit I bought came with a secondary trasportation bag which has no window and better RF shielding. The phone in both bags can't connect, but then without the window, I can't enter the PIN and gain access to the phone either.

Just for the record

http//www.forensicfocus.com/Forums/viewtopic/p=6562541/#6562541

In the comparative tests made by Purdue University
http//docs.lib.purdue.edu/cgi/viewcontent.cgi?article=1033&context=techmasters&sei-redir=1
that particular make/model didn't do very well

In this graph it is clear to see that the Black Hole Bag fails to isolate most of the
mobile phones during the tests. It is evident that SMS messages are the least isolated of
the call types. Voice calls started out penetrating this shield as often as SMS but were
more affected by time. This is most likely explained by the increase in noise in the
communication channel that being placed inside the RF shield causes. As the SNR
decreases the phones have a harder time communicating with the tower despite still
receiving some signal. This supports the hypothesis that SMS messages require less SNR
than the other call types.
Overall the Black Hole Bag had a 54.12% failure rate during these tests.

while still better than others, the really preoccupying issue coming from the conclusions is that no "safe" product was found

It is evident that the shields do not always isolate the mobile phones. None of the
RF shields tested were able to successfully isolate the phones 100% of the time.

Thanks for the info, jaclaz. I wouldn't say I've had anywhere near a 50% failure rate with my version of the Black Hole bag. A couple SMS messages on an HTC Thunderbolt are all I've seen. My personal BlackBerry and several iPhone (3GS, 4S and 5) have all been properly shielded by this bag. I'm less than a block from a tower too, so it's a pretty strong signal area.

If possible, get the phones delivered to you in airplane mode. Since I deal with civil cases, this is usually possible.
