krbonne Posted March 12, 2016 Share Posted March 12, 2016 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.
