Hi,
Inductive coupling is a method of transmitting data between tags and readers in which the antenna from the reader picks up changes in the tag’s antenna. Am I true?
Backscattering is also a method of communication between passive tags (ones that do not use batteries to broadcast a signal) and readers. RFID tags using backscatter technology reflect back to the reader radio waves from a reader, usually at the same carrier frequency. The reflected signal is modulated to transmit data.
I am very confused with the above statements.
Passive tags absorbs energy from the reader, powers up the ciruitary and then communicates with reader.
What is the method of communication/technology used for data transmission in LF, HF, UHF and micrwave range?
If I am not wrong, inductive coupling and backscattering are two differnt technologies for data transmission. Then how are the above statements true?
Please correct me if I am wrong at any point.
