Siemens announces wireless data transfer at 500 Mbps using visible light

Siemens issued a press release announcing the wireless transmission of data at 500 Mbps at a range of 5 meters using a white LED, breaking the previous record of 200 Mbps. The variation of light intensity used to modulate the data is imperceptible to the human eye. Siemens sees practical applications where such a system could be used to transmit data via ceiling lights when WLAN radio frequencies are congested.
