serial data wirless

i need an electric circuit to send and receive serial data wirless , i found one that use TLP/RLP but i didnt find them in my country , is there any other way to make one .

Range? Data rate?

Leon

range (20:50) meter , data rate 9600 .

You need two of those for a complete wireless link. One link could be a regular PC using an adapter like the [[XBee Explorer USB](https://www.sparkfun.com/commerce/product_info.php?products_id=8687) or this [[XBee Adapter Kit](http://www.adafruit.com/index.php?main_page=product_info&cPath=29&products_id=126) with an FTDI breakout board or cable. You can also use the second adapter to connect to a microcontroller. Or use two USB adapters to connect wirelessly between two PCs.

The only circuit you would need is one that your specific application might require, and depending on what the application is you may not need one.

What is your actual application? Without more information on that and what you really want to do other than send data wirelessly, there isn’t much chance of anyone helping further.

The XBees are being suggested as one possible solution to the wireless part of your application. :slight_smile:

He’s saying he can’t order these modules from his country and would like a schematic/instructions to make a serial RF link from basic components. Not that he doesn’t know how to use Xbee’s.

Personally I’m no help and I’m just going to guess here, but unless the original poster gives some indication about his abilities with this, it’s beyond basic electronics skills and would require a significant amount of time and learning to make out of passives alone.

Most any kind of wireless data link begins with an RF module rather than discrete components.

iam making RF Helicopter and i want to control it wirelessly , this products i cant get from my country so i want to make the transmitter and receiver circuits with myself .

walid,

Start here:

If you are very innovative and motivated you could learn all the details of radio receivers and transmitters to build your own.

Transmitters are easy to build but may fall under government regulation. Receivers that work well are hard to design and build. But modifying a receiver is not that difficult.

Are there any Amateur radio operators where you live. They would be able to help you with circuits and parts.

You can also hook this up to an embedded network server.

Lantronix specializes in this, specifically with their Matchport product:

It’s a little on the pricey side, but the interface is really easy to navigate, so you won’t have to spend a whole lot of time trying to figure it out.

Hope this helps.

Lantronix available in “his country” ?

Also their modules consume a LOT of power versus 802.15.4 modules - important if battery powered.
