The basic idea is to have an audio transceiver in various rooms of my house. Each should have buttons like Room 1, Room 2, and so on. Pressing a button and speaking should result in the corresponding receiver receiving the voice signal. Full duplex is not necessary. Frequency range is not important. Would rather avoid (obviously) the 88-108 MHz FM. Range need not be more than 200 metres LOS. I would like some ideas to start going about making this project.
I searched on the forum and Google for wireless intercoms and such, but couldn't find any satisfactory results.
Thanks!
