Hi Folks,
I am a total radio knob, needing help with a project. So thanks in advance for your help and patience.
So I have this idea for a new game that requires a very simple remote control radio device. Basically I want to have a person to person pager, that runs off some form of radio band. Essentially I want to have the function of the call button on a walkie talkie, that makes another unit vibrate. And vise versa. But I don't need any voice communication. So a handheld device, battery powered, and very small, that has a button that pages an identical device via radio, and makes it vibrate. Initially I thought I would use the FRS radio band, but after looking into the FCC rules I believe I discovered that they will not allow that without the ability to transmit voice back and forth.
The travel range I need these to work within is fairly short, say a maximum of 300 to 500 feet, all in line of sight. The only requirements I have is that the devices be as small as possible, have as short of antenna as possible while still working very reliably, and a small battery. So I am assuming to get a short antenna I will need a higher frequency of radio transmission?
So my question to you is, with all your experience with radio, what do you think would be the best radio frequency band to use that would be legal with the FCC without any license? Do you know of a similar product that uses this band that I could check out and see if it would work?
Thanks for your help with this.
