Design Help Needed

[AustinSMU09]

I'm brand new to the forum, so forgive me if this topic has already been discussed. I'm trying to build a remote RF 5-button system in which each of the 5 buttons on the fab will trigger 5 different wireless speakers (alarm). I'm striving to achieve a receiver/speaker size comparable to that of a quarter. I'd appreciate any suggestions that you might have for me. aandres@smu.edu

Thanks!
