    1 Why Did I Write the IoT / M2M Cookbook?

    I have worked in the Wireless M2M for more than a quarter of a century. Twenty-five years ago, we didn’t even have a word for “M2M” or IoT. We developed Machine to Machine devices without knowing that decades later these creations would be called “M2M devices”. Twenty-five years ago, the GSM network for wireless data communication did not exist. I made my first steps in wireless data communication with Frequency Shift Keying (FSK) on Private Mobile Radios (PMR). On PMRs we achieved communication speeds of 3600 bits per second. A little later we started using public analogue trunked radios. These trunked radio systems provided local terrestrial wireless networks on FSK. Years ago, the final public analogue trunked radio network in Germany was taken out of service. GSM jumped in with its Short Message Service (SMS) and Circuit Switched Data (CSD). CSD provided us 9600 bits per second. We could use SMS and CSD for countrywide data communication easily.

Projekte

  • GSM cell locating at EXPO 2000 in Hannover Germany

    –

    Locating of the salesmen for the tickets of the gondola train by a GSM towers. We got all the details of the GSM base stations like position, Cell ID and power level in region Hannover. All this was possible, because I was aware on non documented AT commands to force an hand over from one GSM cell to another cell. Options for cell location of the past and today are described at the link to PDF file. https://www.box.com/s/aa3ea6b74022d84e5d8a
