I had the brilliant idea of building a device that will send GPS location over SMS text messages.
this, after i lost my prototype quad Arducopter last week. it felt not too far, i could hear it, but a few days of searching in the forest gave nothing....
R.I.P. dear copter.
here is the last successful flight, in memory..
to the point,
the Xbees are working at 900Mhz,
and the DroneCell is quad band, but the local cell company is using both 900Mhz and 1800.
should there be interference between them ?
and how can one know if the Dronecell will choose 900 or 1800 Mhz ? given the cell company support both...
