The OpenET Alliance, the industry association that promotes energy efficient wireless transmission through Envelope Tracking (ET), has 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.

Steven Baker, technical director of the OpenET Alliance, said, "It is significant that our membership is drawn from right across the supplier ecosystem, embracing chipset platform, PA and modulator vendors, OEMs and academic institutions. No one supplier has all the answers, so this kind of industry collaboration is key to effective development in the sector."

The updated interface specification for terminals, which has now been published to OpenET members, includes recommended system noise specifications to support full bandwidth LTE signals.

In addition to publishing ET interface specifications, the OpenET Alliance, through its systems working group, is developing a common system simulation model to ensure that all participants share a deep understanding of system issues that underpin specification and design choices. It is expected that this will lead to earliest delivery of effective components and products. Following the success of this early work, additional specification development is planned in 2012 for 'medium power' pico and femto infrastructure, public safety and military applications.
