There is NO licence-free band for a received range of 1km.
This is difficult to digest, as all power output constraints talk in terms of ERP which is a function of bandwidth and Frequency.
Besides, the main rule for Licence-free band operations is Low power Short Range devices without external antennae.
All specifications are in "funny" techno-legal language, less understood by lesser mortals. But the end result is the same: There is NO Licence-free band for a range of 1KM.
Meaning, the rules does not allow Free communication beyond 100m.Are you sure? This action cannot be undone. -
