hi, i am completely new to wireless technologies . so please help me even if it is very basic question. 
i have to transmit potentiometer voltage signal through rf 2.4ghz transceiver for the project ii am working on.
But i dont have any idea how to link pot with the transceiver.Am i supposed to use microcontroller ckt for this or simple ADC will be fine??
I want to know how the connections are made because i dont understand functioning of transceiver terminals .
Thank u
Which transceiver modules are you using???
If you use the XBee Series 1 modules this can be done (kind of).
A pot can be connected to the sending XBee’s ADC input. It would send the ADC value to the receiving XBee which would vary a PWM output duty cycle (which is low pass filtered to a DC level).
Is this what you want to do?
Thank u fr ur reply.
I am using TR24A transceiver .I am using Arduino Uno board on the receiving end. Do i have to use that board on the transmitting end also?? or i can just connect pot to the transceiver directly by some means.??
I have no idea what the R24A transceiver can do.
Post a link to its Data Sheet.
Have you gotten this transceiver working with your Arduino?
Can you send data across?
Does it have analog inputs and analog outputs?

no,i haven’t got it working yet.Like i told you i don’t even know what are all those terminals mean.I don’t think it has any analog i/o’s .It only has power terminals and SPI interfacing terminals.
Well, the data sheet indicates that all interfacing is through the SPI buss (google “SPI serial” and “SPI on Arduino”) and a few additional status/control lines.
But no information on what commands, data format etc is required and I saw one obvious typo in the DS.
There is much more info needed to use this RF module. Is there a programming/interface guide from the company that sells this?
If not then it is probably best to avoid this module since you will be doing a lot of guessing and trials to maybe get it working.
I’ve done this exact thing using a pair of our nRF24LE1 breakout boards, using the chip’s built-in ADC on the input side. I strapped a SPI DAC (Microchip MCP4921) to the output side so that I had the same analog voltage on both sides of the link.
