433MHz (433.92MHz in fact) is the most used frequency on earth. It's a free use unprotected Short Range Devices frequency used by a lot of devices.
To name a few, car keys, door openers, external wireless thermometers
and pressure sensing devices, radio ham TV,... and
wireless alarm systems.
Apparently not. Seehttp://www.wpc.dot.gov.in/faq.asp#3What are the license- free bands?433 MHz is not listed there.
because is a industrial standard
No -- the RF in RFID means radio frequency, ~900 MHz maximum. The infrared spectrum ranges from 1 THz (= 1,000,000 MHz) and up -- a big difference in frequency.
' GSR 564 E ' is a certification required in India for low powered RF products that uses frequency band between 865-867 MHz.
Yes, but it will be less efficient than one designed for FM.
Transmit RF frequency subtract to the Receive frequency
