Interface of 8051 with antenna

vinay dhuru

I want to interface antenna with microcontroller like 8051 to transfer data from PC.PC will be remotely located and hence to send data I require interface of antenna at both ends ie PC and 8051.Is this possible and how?Can I get circuit diagram

    You don't interface an antenna to a microprocessor. You interface an antenna to a radio transmitter or a radio receiver. This transmitter and/or receiver may be interfaced to a processor.

    What kind of distances are we talking about?

    What knowledge do you have about radio technology?

    There are existing 433MHz transmitters and receivers that has RS232 interface or TTL interface - you can use them at low baudrates together with a serial port. However, the 433MHz band is quite noisy since it isn't regulated - on the other hand, you'll have quite a lot of work at hand if you want to build equipment to use a regulated frequency band.

    Do you have a clear view between the two points? Maybe you can use a laser link instead? It tends to give higher baudrates and can be quite easy to implement.

    Or switch to an ARM project and use a processor with Ethernet support. Then use a WIFI link or similar.

    External WiFi modules are available that could be used with a suitable 8051 derivative...

    Sir,

    Can you tell me the Part No. for RF transreciver I.C. which is easyly available in India and low cost ?

    I want to interface it with Antenna & 8051 uC.
    The Communication will be with in 1 Sqr.km range.
    The Communication will be TxD & RxD line of 8051 uC.

    Actually I want to send & receive some packets among 8051uCs.

    PLEASE LET ME KNOW THE PART No. tanmay_roy8@yahoo.com
    Thank You.

    I don't think anyone here is going to be able to tell you the part number that will work best for your application. That is for you to decide. You need to look at the available technologies, which include wifi, zigbee, and a host of other technologies and decide for yourself.

    Again, here is what YOU need to do:
    -determine the requirements for the communication system
    -determine which technology will meet those requirements
    -determine which part that uses that technology will best suit you needs.

    Range is a linear measure - not an area.

    What do you actually mean by this?
