Remote control for open/close gate door

Hi friends,

I'm new in rf world (I'm working with mcu mostly, and analog electronics (less and less in past years)).

I need to make remote controll to open/close gate door (for car entrance), something similar to remote control's on car alarms.

Problem is that I need 6-7 remote units (with same code, frequency or ...) and one base unit which will get command from remote unit to open/close.

I'm sure that this is piece of cake for you.

Some links on working remotes stuff, or approved schematics are welcome.

Thanks in advance.


Mr.Cube

you can use CC1000, CC1020 ICs from TI or ADF7021N from Analog devices.

But you need to have rf knowlegde.

You can also use ready modules like as www.hoperf.com,www.linxtechnologies.com,
