Guys I need to transmit a signal at the range of 0 to 10 meters (aprox) .which signal can I use???? RF or IR..

If RF .then how can I reduce d distance range to RF ???

Why not a laser diode beam? IR if the beam should not be seen. Optical if this is not a requirement. Can be modulated for security.

I want to do it in low cost and I wanna transmit the signal in 360°

Do you mean a spherical wave front like a radio transmission? Then RF is probably best. Or a spherical LED lamp modulated by the signal being transmitted.. The receiver may need to have a telescopic collector to eliminate external interference.

The RF transmitters generally operate on a voltage range. The lesser is the voltage, the lesser is the range.

The 433 MHZ RF transmitter has the approx range of 100 meters ... How can I reduce its range to 0 to 10 meters????

Difficult to precisely confine the range. Run it on a lowest permissible voltage. That's the most you can do.
