Siemens Brings GPS to the Cell Phone Network Siemens has developed a solution that`s making it easier for mobile phone companies to offer their customers virtual guided tours and other positioning services. This is possible thanks to A-GPS (Assisted Global Positioning System), which Siemens is integrating into cell phone networks. Initial tests of the new positioning system at the Czech cell phone operator T-Mobile in Prague were successful, and Siemens Communications intends to market the system beginning this autumn. Since there currently are no handsets for this technology on the market, a Siemens SX1 cell phone equipped with an A-GPS chip was used in the test phase.
