Contrarily, if the frequencybandwidthofsignal is finite, the time length of signal will be infinite when sampling in frequency domain, the time folding phenomenon will certainlyhappen.
The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency.
By 2005 the world's bandwidth could grow a millionfold, making it "virtually free and virtually infinite, " says James Rothnie, an EMCsenior vice president.
