Information Darknet for hackerspaces
Status Alpha


Off the record darknet to link hackerspaces together, using pre-existing free technology to serve our own out of band network without the need to depend on government-controlled infrastructure.

Technology

Radio

There are a few options for using radio:

Band Frequency Spacing Modi Antenna size Max. power Max. speed Max. reach (norm.)
CB (27 MC) 27 MHz 10 kHz FM, AM, SSB 11m (or 5.5 (or 2.75)) 4 W (FM/SSB), 1 W (AM) 9600 baud 50 km
UHF LPD 430 MHz 12.5 kHz FM, WFM 70cm 10 mW 9600 baud 10 km
UHF PMR 446 MHz 12.5 kHZ FM 70cm 500 mW 9600 baud 10 km
Wifi 2.4 GHz  ?  ? small  ? watt 300 mbit 2 km
