Power saving for combined GSM/GPS modules

  • Our tiny combined GSM / GPS modules GM862-GPS and GE863-GPS now come with a low power chip for the GPS part inside. You also get nine upgraded features of the firmware. Further facts are listed at

    Changing of the GPS chip does not touch the RTTE approval.


    We are glad to offer the features without changing the price. Further Round Solutions will save you power by using our low power GPS antennas. We offer the worlds smallest GPS antenna ANT-NXG354 (12x12 mm only) with a two stage LNA (25dbi) and a supply current 13 mA only.


    Telits calculation of power consumption with the old chip set:
    70 mA ±20%, including 50 mA for the GPS chip and 20 mA for the antenna LNA. Part # GM862-GPS, GE863-GPS


    Telits calculation of power consumption with the new chip set:
    55 mA, including 35 mA GPS for the GPS chip and 20 mA for the antenna LNA. Power saving = 15 mA. Part # GM862-GPS-LP, GE863-GPS-LP.


    Round Solutions calculation with the new chip set and ANT-NXG354:
    48 mA, including 35 mA GPS for the GPS hardware and 13 mA for the antenna LNA. Power saving = 22mA

    That means Round Solutions clients can save 46% more power by following our hint.


    Based on our embedded GSM antenna ANT-GXE475 you can save even more power. It has 30x6x5 mm only and is non-sensitive against the hand effect. Round Solutions customers can build the smallest devices, because we offer the tiniest GSM or GSM/GPS modules as well. They can develop the cheapest products, because our BGA modules will save money since no connectors and RF-cables are needed. Last but not least you will benefit with the fastest time-to-market by using of our rapid prototyping of plastic cases.
    All components and services will be presented on November 14th – 15th at the http://www.telemobilityforum.com with our presentation: "Making of mobile devices like playing with toys"


    BTW, will you visit the Monza, Italy M2M event too? Are you interested to arrange a meeting?
