Re: [ipwave] IPWAVE Side Meeting

[Chris Shen <[e-mail]>]

Hi Alex,

I answer your questions as follows:

- is the manual available? ("Made a new manual for running OCB mode")
>
Yes, it is in the following github link:
https://github.com/ipwave-hackathon-ietf/ipwave-hackathon-ietf-106/blob/master/IPWAVE-Manual-Hackathon-IETF106-v0.2.pdf



> - have you made a patch file?
>
I didn't make patch file for this implementation.
Based on existing resources, there are some patch work to enable
OCB mode in the Linux kernel.
One of them is much concrete, which was made by Czech Technical University
in Prague and Volkswagen.
The resource link is as follows:
https://ctu-iig.github.io/802.11p-linux/
But when I follow their instructions to configure OCB mode, there
are some unclear steps and some compiling errors coming out,
so I have modified the Makefile and explored other ways to configure
OCB mode, which is shown in the manual.

I didn't use QoS. For the current webcam streaming, I use gst-launch
from Gstreamer. This gst-launch uses UDP and RTP to stream webcam.

I checked packet dump, there is no QoS information, so I believe the
packets
just use 802.11 Data headers.
I will send you the packet dump later, since I didn't save them.



> - the wifi card wilocity is on USB or is it internal to the laptop?

For the current test, we replaced the original wifi card inside a laptop
with an Athero wifi card using ath9k driver. This wifi card uses PCIe-mini
interface to connect with the laptop.
We also use the laptop internal antennas for 5.9GHz band. Initially,
we are not sure if the antennas of the testing laptop can support 5.9GHz
band, so we connect the wifi card with external antennas that support
5.9GHz.
After testing, we found that the laptop internal antennas can also support
5.9GHz band, so we just use them.
If you have a USB dongle that has PCIe-mini interface, I believe an Atheros
wifi
card can work as well, but you need to have external antennas to connect
with
the wifi card on the USB dongle.

Thanks!
Chris.
