Method and apparatus for converting optical signals to radio channels
First Claim
1. A method for converting a pulse modulated input signal (A) to a radio frequency signal (D, E), the method comprising the steps of:
- i.) receiving the pulse modulated input signal (A), wherein the pulse modulated input signal (A) is an optical signal, wherein the pulse modulated input signal (A) is received from an optical controller (1);
(ii) decoding the received pulse modulated input signal (A) into a decoded data bit-stream (B);
iv.) modulating a radio frequency signal (D, E) with the decoded data bit-stream (B);
v.) transmitting the modulated radio frequency signal (D, E); and
vi.) converting the received pulse modulated input signal (A) to an electrical signal to charge a battery used to operate a transverter.

Abstract
The invention relates to a conversion of a pulse modulated signal to a radio frequency signal enabling use of applications and protocols designed for wireless optical links on radio frequency channels. The method comprises receiving the pulse modulated input signal, decoding the received pulse modulated input signal into a decoded data bit-stream, encoding the decoded data bit-stream into a recoded data bit-stream, under use of the recoded data bit-stream modulating a radio frequency signal, and transmitting the modulated radio frequency signal. In the receiver path a received radio frequency signal is converted to a pulse modulated output signal by the steps of demodulating the received radio frequency signal into a demodulated data bit-stream, decoding the demodulated data bit-stream into a received data bit-stream, encoding the received data bit-stream into a pulse modulated output signal, and forwarding the pulse modulated output signal.
