[[Grassroots]] efforts have also led to [[wireless community network]]s widely deployed in numerous countries, both developing and developed ones. Rural wireless-ISP installations are typically not commercial in nature and are instead a patchwork of systems built up by hobbyists mounting antennas on [[radio masts and towers]], agricultural [[storage silo]]s, very tall trees, or whatever other tall objects are available.

Where radio spectrum regulation is not community-friendly, the channels are crowded or when equipment can not be afforded by local residents, [[Free-space optical communication#LEDs|free-space optical communication]] can also be deployed in a similar manner for point to point transmission in air (rather than in fiber optic cable).
