why do you need the sniff codes to create a "distance teaching system"? if you have the openBTS working you can use normal phones with it. i don't see how does it relate to GSM Sniffing at all... then again, I'm not a PhD student Cheers, Francisco On Mon, Jan 24, 2011 at 3:57 PM, Marten Christophe <technosabby(a)gmail.com>wrote;wrote:

People prefer to donate (money, items) to organization that have a proven track record, that one can relate to (e.g. 'Die Tafeln' in germany, organizations that provide heating for homeless in winter..). You should start building some trust, this involves writing code in our community. So here is something you could do. 1.) Setup a wiki/site for your phd at your university and point us to it 2.) Put the plans for your system on that page 3.) Build a prototype, thanks to the invention of layers you don't need to have any hardware for that. E.g. start with a prototype that is announcing classes through the CBCH with your own encapsulation of the message. Build the code based on osmocomBB to receive this... 4.) Go for other physical channels with more bandwidth, again no RF is needed you can just start using a SDCH and make the l1ctl connect to your repurposed BTS code. 5.) Sylvian has shown how to get raw BURSTS from the DSP, maybe he is kind enough at this state to help you in transmitting raw bursts. You could realize the 3rd) with two osmocomBB then... at this point you could even do 4th. 6.) if you have done 1.) to 5.) have a prototype in software, some basic illustration that the RF side is working. Ask for donations for a USRP1 and the flex frontends and the antenna. I am sure that once you have shown that 1.) to 5.) are done, that you have a NGO at hand for a field trial that one can make a tax deductible donation to that NGO and they will buy you the USRP from that money. so please build the trust by building up the system regrads holger
