The mobile electronic device may request a communications link on the lighting communications network and detect modulated illumination light emitted from the LED based illumination device. The modulated light may include an optical code. The mobile electronic device may determine the optical code from the modulated illumination light and communicate an indication of the optical code to the LED based illumination device. The LED based illumination device may determine if the indication of the optical code is correct and provide, in response, a communication link to the mobile electronics device on the lighting communications network. ## Claims ### Claim 1 A Light Control and Data Interface Module (LCDIM) comprising: a radio frequency transceiver;
