    Welcome to EP.
    "wireless" could mean a lot of many different things.
    You need to be more precise.

    WIRELESS meand w/o wires , it means a system with RF transmiter and a rf receiver at the same frequency
    In this case the tansmitter also transmits orders to the receiver that turns ou and down certatin relays accroding to the order sent by the transmitter
    whats so hard to understend ?

    i intend to do a receiver transmiter that is like those used in the industry
    I intend to use an ARDUINO relays shield like those

    I will need to a atransmitter and a receiver

    Frequency should be like used in the industry , Distance alike

    When you say "industry" ,what exactly do you mean?
    Don't you know what distance do you need?

    Industry means factories , it might be used as a garage door opener as well
    Regarding frequency , it might be infra red maybe better than RF , more immune to noise .

    Now im clear ?

    Not clear enough.
    Industry and factories are general terms and mean practically nothing.

    Infrared is line of sight, mostly short distance many times in a room.
    RF for garage doors is a very common 315/433Mhz , outdoor, range less than 50M or so.
