i am intrested to control things wireless (like remote control cars ) .and i dont know any thing about that where to start and how to start and what are the books.

pls tell me the prerequisites subjects to be learned

and the subjects (or books ) to be learned to design such circuits

( the educational details about me : i am doing my bachelors degree in electronics and communication )
thankyou

Try XBee or nRF24L01+

Talking electronics , google it .

This field has a lot of topics to get familiar with.

A partial list:

* How to send and receive radio broadcasts
* How frequency bands are allocated for radio-control usage
* Legal regulations (public, private, commercial)
* Coping with interference and reliability problems
* How to send several command signals on one frequency
* How to distribute commands to devices on vehicle
* How to operate a servo
* Electronic speed control circuitry
* Miniaturization and weight considerations
* Motor types and specifications
* Methods of propulsion, steering, etc.
* Power utilization on vehicle
* Battery selection and management
* Auxiliary lights, camera, mechanical systems, etc.
* Coping with vibration, dirt, moisture, etc.

This is a great deal to cover. The best way to get a grasp of it all is by hands-on experience with an R/C car, boat, plane, robot, etc.

It should not be difficult to find free how-to instructions about R/C on the internet. It's an easy field for people to be excited about.

If you want to get moving quickly at the start, obtain a manufactured radio transmitter and receiver system, instead of trying to make it yourself.
