    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Hi all,

I am after some advise/help/for someone to shed some light please.

I am a final year Computer Networks student and have been given an assignment to discuss SDR and implementing numerous protocols within a single device (GSM, UMTS, LTE, 802.11ac, Bluetooth 4.0, NFC).
Whilst I do already have a good understanding of the 802.11ac and Bluetooth protocols, I am absolutely clueless about the others. I have spent the last 3-4 days reading various pages and sites discussing RF, SDR and the numerous protocols to no avail.

If someone could please shed some light or at least point me in the right direction, it would be much appreciated.

Many thanks,

Somewhere in this room. Right now, you're very col
This website plus a $20 RTL dongle (perfect for a "starving student" budget) should provide you all sorts of possible uses and info for your research: rtl-sdr.com - A blog about RTL-SDR (RTL2832U) and cheap software defined radio. As an example, I'm using one to provide the feed I'm currently hosting, which is in essence a digital trunking scanner (normally a $400-$500 device) that I put together for less than $20.

Good luck!
