Software Radio / Data Tunneling - The Well Tempered Hacker Ep 5

Taking another look at Software Radio, this time with the Ettus Research E100, we create a data tunnel and send a network over it. The E100 includes an entire Linux machine within the device so the need for an external computer is gone. We can simply use the internal Linux machine to route packets and control the radio. Two E100s are shown connecting to each other and granting Internet access to a small WiFi Access Point. We use GNURadio's tunnel.py (from the examples directory) which creates a tunnel device called gr0. Adding an IP and configuring a network to route through it is all that is needed to get this going.

E100 hardware is available from http://ettus.com/ for roughly $1,600.00 each. Parts list: E100, RFX900, VERT900

Ubnt has 900Mhz, no ?

[anders94]

@hypnologic Ubnt = Ubuntu? And 900Mhz is a radio frequency. ??? Not following you.

[hypnologic]

@anders94 Ubiquiti Networks.

[anders94]

@hypnologic I understand they are within 2.399-2.485 GHz (Airview2/EXT) and 895-935 MHz (Airview9/EXT) - generally unlicensed bands but with power limits. Same idea though, yes.

@anders94 Example For Non-Line of Sight links - miniPCI cards: doodlelabs RouterBoards and advanced software: MikroTik

[anders94]

@hypnologic Yep, I've played with the RouterBoards - nice devices.

[anders94]

@Zwank36 I'll give it a try.

[Zwank36]

@anders94 if you add compression on top of the encapsulation shouldn't be that bad :P

[anders94]

@Zwank36 Technically they are but I'm guessing we would be down to something like a 20k transfer rate. I have thought of doing an episode on IPSec tunnels - might have to roll that one out.

@JWTvideos Thanks for the feedback. Feel free to suggest other topics.
