M2M IoT Cookbook 400x248 IoT M2M Cookbook abstract in the newsThe example of a locating device based on cellular modules (GSM, HSPA, LTE) and GNSS modules (GPS, Glonass, All Galileo) explains how to develop a complex IoT / M2M-device with embedded antennas. The person, who has to develop a telemetry device, ignores the part of GNSS. The 20 years of experience in the development and consulting wireless devices is included in all chapters. The integration of antennas has been paid special attention. The antenna is the key to success with any wireless application. The simulation, and the result, is a quad-band GSM antenna and is explained in detail.

Each developer can easily copy the result without the use of mathematics. In the example of the vending machine, the self-made, integrated antenna not only saves the external antenna, but also the coaxial socket and installation as well. The same antenna can save the expensive SMT mount cellular chip antenna in a locating device and is easily adapted to the Epsilon R of the housing. Other sub-themes are power supply and choice of carrier (USSD, SMS, CSD, DTMF, GPRS) approvals. Typical mistakes of first-time users are addressed too.

The developer selects the antenna design first and then builds the device around the antenna. This results in a large cost saving for hardware and installation. At the vending project the estimated saving was 4,000 installations x $ 10 = $ 40,000. The integrated antenna with the optimised ground plane is so good that during redesign the switch and the coaxial socket to the external antenna were excluded.
