If the broadcast range of your transmitter is more than a few metres, you count as a radio station and need a proper license to broadcast.Why do you need to broadcast 5km?
Most countries have strong restrictions FM transmitters. Personal use is usually limited to a few meters. To be allowed to transmit to several kilometres you often are required to have some form of radio station permit. As to how to physically get that kind of range: Bigger antenna and more power I would guess but I can't help on the details.
