LG Electronics has demonstrated a LTE-CDMA

LG Electronics has demonstrated a successful LTE-CDMA handover for handsets for the first time. The demonstration was held at the Nortel R&D Center in Ottawa, Canada last week.

LG Electronics displayed uninterrupted data transmission technologies, including video downloading, web surfing, and Voice over Internet Protocol (VoIP), using a handset it has developed.

LG Electronics' handset, or the M13 4G LTE trial device, is adaptable to both CDMA EV-DO (850/1900MHz) and LTE (700MHz). It obtained approval for the handset from the US Federal Communications Commission in June.

Based on about 300 LTE-related patents it has obtained and its success in the world's first demonstration of commercialized LTE technology in 2007, LG Electronics is now leading the standardization of LTE in the global market.

LG's LTE IPR Quality Evaluation

Recent LTE IPR analysis by TechIPm showed that LG's LTE patent portfolio is in high quality compare to other LTE IPR holders: To evaluate the quality of LG's LTE IPR for OFDM/MIMO standards, patent disclosers for each essential patent candidate are compared to the technical specifications for LTE OFDM/MIMO standards (TS36.211 V8.70). Total of 16 patent applications published in the United States before Aug. 1 2009 in the lists of patents declared essential to LTE appear at the ETSI IPR Online are used in the analysis. As for the most described field of technical specification, Physical Random Access Channel (PRACH; Section 5.7) was the top in LG's OFDM/MIMO essential patent candidates. As a measure for the essentiality of the candidates, Essentiality Index (EI) is evaluated: EI : Criteria E0 : Patent discloser is nothing to do with LTE technical specifications E1 : Patent discloser is weakly related to LTE technical specifications E2 : Patent discloser is partially related to LTE technical specifications, but required further analysis E3 : Patent discloser is partially related to LTE technical specifications E4 : Patent discloser is related to LTE technical specifications overall E5 : Patent discloser is strongly related to LTE technical specifications Only 18% of the LG's OFDM/MIMO essential patent candidates are classified as E2 and E0. Nearly 90 % (eight E3, three E4, and two E5) of the LG's OFDM/MIMO essential patent candidates are classified as high value of EI for the essentiality.
