wireless communication through RS232
Range should be more than a kilometer.
Can anyone help me ?
I want to send only ONE BYTE at a time.
you must have a transceiver on either side....
Based on the band ur going to select there are several transceivers available....
u can use zigbee modules....
there are several other options 2...
check out if anyone can suggest a low cost solution....
Zigbee may not offer that distance. you get RF transceiver for that range.
Hi shahbaz,
Our company offers a product that can create a wireless serial cable for you at 1km. Serial data that is fed on one side is simply regenerated on the output, along with retransmissions and data verification. For more distance you can also use a directional antenna. The serial input is UART, but we have examples of how to convert it to RS232. More information is available at Starman Electric - Wireless RF Modem I/O Transceiver Modules
If price if a concern, please email us and we can work something out.

There are some RF modules from HOPE RF. you can use them. i come to know about one company here which have made USB2RF converter also.
