A few days ago the first edition of the Wireless Telegraph was published. 37 000 copies were printed. The magazine relates to all important technologies such as NFC, Bluetooth low energy, GPS, Glonass, Galileo, ZigBee, 6LoWPAN, GSM, GPRS, EDGE, UMTS, HSPA, ANT + but also ISM in Sub G and 2400 MHz. Even the new WiFi N standard at 2.4 GHz and 5.8 GHz is confirmed by industry-standard ICs and modules. When the decision was made to develop the magazine it was not known that Google in May 2011 will publish NFC, 6LoWPAN and Android @ Home at I/O in California. That Facebook Â will attach the M2M protocol of IBM (MQTT) was not predictable. That smartphone with NFC and Bluetooth Low Energy will come in 2011 was known. In the last weeks the iPhone 4S (Bluetooth Low Energy), Motorola Razr Droid (Bluetooth Low Energy) and the Nexus Prime (NFC) were launched. By the end of the year it is determined that a few surprises on Android will follow. And before I forget to mention – Bluetooth Low Energy also named Bluetooth 4.0, was renamed to Bluetooth Smart and Bluetooth Smart Ready.
You might have gotten a copy of the Wireless Telegraph. Nevertheless, there are German and English editions in PDF format available:
Please find my article on page 20 and 21: “Power consumption of tracking devices”. The article shows the challenges and solutions for the construction of low-energy M2M devices with and without GPS. The best approach can often work out only at the customer locally. Only when the size and shape of the housing or even possible objects in the near of the unit are known, the optimal antenna design can be figured out. The countries where the product will be used will influence the hardware design significantly as well.
If you are interested in a free consultation and a concept for your M2M device, then send an email to harald.naumann (at) gsm-modem.de or give me a call at. I will present you my experience (25+ years in radio / 15+ years in GSM and GPS). On request you can get references to wireless projects for all over the world. Thank you in advance for any challenge.
