Hi,
I am kristoff, ham radio operator ON1ARF.
One of the things I am interested in this: pi@hsmm23-2:~ $ iwconfig
wlan0 IEEE 802.11bgn ESSID:"HSMM-MESH-ON1ARF" Mode:Ad-Hoc Frequency:2.357 GHz Cell: Not-Associated Tx-Power=30 dBm
(...) ra0 Ralink STA ESSID:"" Nickname:"MT7610U_STA" Mode:Ad-Hoc Frequency=5.82 GHz Cell: 3A:7C:B3:6B:19:FC Bit Rate=65 Mb/s
Modifying kernel-modules for wifi for ham-radio mesh-network applications (HSMM-mesh).
Sofar, I managed to extend the range of the certain wifi devices to the complete ham-radio bands (2.3-2.45 Ghz and 5.65-5.85 Ghz), but I like to go further then this:
- changing the frame-formats to make then incompatible with normal wifi (especially on 2.4-2.45, 5.65-5.71 and 5.735-5.835, which overlap with normal wifi)
- longrange wifi: e.g. the 10 MHz or 5 Mhz bandwidth version of 802.11a-2007 (certain atheros chipsets should be able to do this ?)
- reducing the kernel-drivers to ham-radio use only (remove 802.11n and ac, remove encryption, only ad-hoc mode).
Does anybody have any practicle experience with this?
My current platform is on RPi (by cross-compiling the kernel on ubuntu LTS).
This is intended for licensed ham-radio operators that have permission to operate on the 13 cm and 6 cm ham-bands.
Cheerio! Kr. Bonne.
