IEEE approves Panasonic's PLC Technology

Panasonic Co., Ltd. and its subsidiary, Panasonic System Networks Co. have developed jointly a PLC (power line communication) technology that has been approved by the IEEE Standard Association as the base technology in the IEEE1901 standard. The IEEE1901 standard documents will be released in the beginning of 2011.

The technology allowing Panasonic's PLC technology to coexist with other PLC technologies-proposed by the two companies in conjunction with CEPCA2-was included as part of the approval. Prior to its approval by the IEEE1901, this coexistence technology was approved in June of this year for ITU-T G.99723.

The approved technology, Wavelet OFDM, is used in products that adopt Panasonic's HD-PLC3 high-speed power line communication technology. Wavelet OFDM is a proprietary technique developed by Panasonic. Wavelet OFDM uses OFDM (Orthogonal Frequency Division Multiplexing) to achieve efficient high-speed data transmission by applying wavelet conversions orthogonally to each subcarrier.
