FM broadcasting
VHF Radio waves do not travel far beyond the visual horizon, so reception distances for FM stations are usually limited to 30–40 miles (50–65 km) They can also be blocked by hills or buildings.
Cell Broadcast
Cell Broadcast is a mobile technology that allows messages (up to 1395 characters) to be broadcast to all mobile handsets and similar devices within a designated geographical area (polygon). The broadcast range can be varied, from a single cell to the entire network.
