Wireless Power Consortium Pushes for "Qi" Standard

The Wireless Power Consortium (comprised of Samsung, Sanyo, Olympus, Philips, Texas Instruments, and others) has started a push towards a wireless charging standard under the moniker "Qi" (pronounced "chee"). "Members of the Wireless Power Consortium are reviewing version 0.95 of its technical specification which defines a proposed standard for charging devices, using up to 5Watts power, delivered by electromagnetic induction. The spec could evolve into a standard — and will be demonstrated by multiple vendors on September 15th to 16th. ... It is less ambitious than the system demonstrated this summer by Witricity, which operates at a distance of a few meters, using resonance, which the company claims has green benefits through replacing disposable batteries."

    It's called pinyin and is the standard romanisation of Chinese characters. It is used in China and therefore they DO use the "latin script".

    Qi, as in the Chinese romanization of æ£.
    This is the same "qi" as Taichi's 'chi'. The life energy
    It's the same 'chi' as the japanese 'Ki' æ-- as in "Tenki" (weather)

    Comparing the peak power of GSM to average power of this system is misleading at best (gsm transmits only 1/8 of the time due to TDM) and a lie at worst (GSM power control almost always pushes the level 10-20dB below that).

    Then 2W max is on 850/900MHz, 1800/1900 has max 1W.
