The OpenET Alliance announced its first wave of members, and the release of an updated interface specification for cellular terminals.
The alliance membership includes Altair Semiconductor, Anadigics, Huawei, Maxim, Nujira, Sony and the University of Florence.
Traditional RF front ends have become increasingly inefficient as more data is packed into the radio spectrum through standards such as 3G, 4G and Digital TV. Envelope Tracking is the most effective wide-band power optimisation technology for the RF front end of 3G and 4G handsets.
Originally developed in the 1930’s, ET is now increasingly seen as the only viable solution for energy efficient, broadband 3G and 4G products. For consumers it promises smartphones that will last far longer on a single charge, and can support multiple frequency bands for global roaming. For network operators and broadcasters it offers the potential of a 66% reduction in transmitter-site energy costs.
