Update IoT / M2M Cookbook, 3 hour Antenna Tutorial, IoT at Electronica in Munich
This quarter I have a lot of IoT / M2M news for you:
1. Update IoT / M2M Cookbook
Since 4 weeks the update is on the server, listed here:
More than 12 pages are related to ceramic chip loop antennas for GPS/GLONASS and Bluetooth. Loop antennas have no hand effect and will not have a resonant frequency shift by touching the enclosure or PCB.
2. My three-hour antenna tutorial at Wireless Congress in Munich, 9th. to 10th. Nov 2016
Parallel to the exhibition Electronica this year is the two-day congress at the same location. The agenda of the congress looks great. There are four training rooms in parallel. Every presentation and workshop are related to Wireless IoT. See agenda here: and I will share our experience and will show how to design in antennas. My presentation on the 10th. of Nov is called “Self-made PCB antenna versus chip antenna”.
Every participant will get three Flex-PCB-antennas free of charge.
3. Latest wireless modules and antennas at Electronica in Munich, 8th. to 11th. of Nov. 2016
The wireless IoT is already so big that the exhibition Electronica offers one hall (4) for wireless technology. My will stay at hall 4 booth 452:
At hall 4 you can find 100+ stands related to wireless communication.
On 10th. of Nov. I will from 1:00 PM to 6:30 PM at the Wireless Congress (Three hour Antenna Tutorial)
4. Seven pages article about NB-IoT and LPWAN
One week before the exhibition in Munich begins the magazine “Elektronik” will publish its special, yearly edition on “Wireless”. The magazine will contain a seven pages article about NB-IoT and LPWAN written by me. I assume they will publish it online here as well:
The combination of the congress and the exhibition will save your travelling time. What about stopping at hall 4 booth 452 and grabbing some sample antennas and the special edition of the magazine? What about sharing and staying at the three-hour antenna tutorial? What about to talk face to face abut your next wireless project?
Will we meet each other in November in Munich? Many thanks in advance for a confirmation by email to harald.naumann (at)
Best regards from the North of Germany

Space shuttle #LPWAN takes off:
As the captain of the space shuttle #LPWAN N.B boldly leads his crew to the outlying regions of the (mostly) nice blue planet called Earth where no man expected to find a wireless network before. Often, the recurring characters of S. and L.W. support him in reaching his mission goal on the proviso that they are not asked to wear a red shirt. The Ground Control (from where it also talks to Major Tom) has its base in the rooms of #akorIoT ( The leaders of Ground Control are W.0. and H.N. Captain N.B. and his Ground Control team often have conflicts and misunderstandings, because N.B. is independent-minded and does not always follow the orders of W.0. and H.N. taking the Kirk Kobayashi Maru hack as an example to follow.
Please find the first three episodes of the adventure of space shuttle #LPWAN below:

+++ Sunday 13th of August 9:00 after take of the Space shuttle #LPWAN +++

Ground Control to the #LPWAN shuttle: “Can you see all the #NBIoT BTS from space?”Watch the Great Wall of China drift to the West and detect the 400,000 NB-IoT China Mobile base stations. Then I want you to warp over to Germany and stop off at the capital city Berlin and detect the NB-IoT BTS. The list of further 13 German cities with the NB-IoT coverage is posted publicly on my blog. The confidential list of further NB-IoT BTS can be had via encrypted email detailing the further cities. Over and out.”

+++ Sunday 13th of August 10:21, the Space shuttle #LPWAN reaches German airspace +++

Ground Control to the #LPWAN shuttle: “Captain N.B., I told you to visit Berlin, Bochum, Bonn, Chemnitz, Dortmund, Duisburg, Düsseldorf, Erfurt, Essen, Gelsenkirchen, Köln, Leipzig, Leverkusen and Mannheim as listed in my blog:

Dresden was on the confidential list in the encrypted email. You made a secret public! Follow my orders and monitor the 14 cities in the public list first. Over and out.”

+++ Sunday 13th of August 15:10, second misunderstanding of Captian N.B +++

Ground Control to the #LPWAN shuttle: “Captain N.B. please follow my instructions and visit the 14 German cities with public #NBIoT coverage first! You are driving me crazy!!! I gave you no order to visit the parking garages covered by Deutsche Telekom’s NB-IoT technology in Hamburg, Darmstadt, Duisburg, Dortmund, Merzig and Moers. At no time did I instruct you to monitor the NB-IoT coverage in Dresden. I did give you the order to visit the 14 cities Berlin, Bochum, Bonn, Chemnitz, Dortmund, Duisburg, Düsseldorf, Erfurt, Essen, Gelsenkirchen, Köln, Leipzig, Leverkusen and Mannheim. After that, we can talk about further visits in other regions. Over and out.”

Die erste öffentliche UDP/IP per akorIoT im Netz der Telekom beim NB-IoT-Seminar in Berlin
Am 21. Juli 1969 betraten Neil Armstrong und Edwin Aldrin den Mond. Am 14. Juni 2017 betraten MM1 und Triptec mit Hilfe der Deutschen Telekom, Quectel und ST Microelectronics elektronisches Neuland. Es wurde die erste UDP/IP mittels akorIoT auf einem Server von MM1 versendet. Die Baupläne der Apollo 11 waren sicher ein großes Staatsgeheimnis. Die Hardware zum Übertragen der der UDP/IP ist offen und nennt sich akorIoT. „akor“ ist das urkeltische Wort für „offen“. Da der Arduino-Header genutzt wurde, lässt sich das akorIoT einfach auf ein #Arduino UNO, eines der 33 verschiedenen ST Microelectonics Nucleo, oder auch eines der vielen anderen MCU-Kits mit Arduino Header montieren.

Über 100 Teilnehmer und Referenten konnten am 14. Juni gemeinsam erleben, wie eine UDP/IP mittels einer offenen Hardware auf einen Server im Internet gesendet wurde. Die Beteiligten an dem historischen Ereignis sind nachfolgend genannt.

1. MM1 Technologies aus Berlin -
Bisher wurde die #NBIoT -BTS in Berlin meist nur zu Testzwecken mit Evaluierungs-Kits verschiedener Hersteller genutzt. Die Meldungen gingen zu Testzwecken normalerweise auf den UDP-Server der Telekom. Am 14. Juni kam aber nun erstmals ein akorIoT mit STM32 Nucleo zum Einsatz. Es wurde diesmal kein Standard-Kit genutzt. Diesmal wurden die Meldungen auf den Server von MM1 gesendet und von da weitergereicht. Der Quellcode dazu wurde von MM1 entwickelt.

2. Triptec aus Lübeck -
Triptec hat das akorIoT entwickelt und produziert. akorIoT ist ein Funkadapter mit Arduino Header und NB-IoT-Modul BC95 von Quectel. Neben dem BC95 ist dort auch ein GNSS-Modul L76 von Quectel bestückt. Des Weiteren befinden sich Sensoren für Luftfeuchtigkeit, Temperatur und Luftdruck auf der Platine. Das akorIoT wird auch mit dem Multimode-Modul BG96 (NB-IoT, Cat-M1, GPRS) produziert.

3. Deutsche Telekom -
Das Seminar fand im Schulungsraum mit Namen hub:raum der Telekom statt. Die NB-IoT SIM-Karte und die SIM-Karten für die Teilnehmer wurden von der Telekom gesponsert. Im hub:raum befindet sich eine NB-IoT-Basisstation.

4. ST Microelectronics -
STM hat die MCU-Eval-Kits vor Ort gesponsert. Weiterhin sponsert STM die Nucleo-Kits für das NB-IoT-Hackathon am 23. und 24. Juni in Berlin.

5. Harald Naumann
Harald Nauman ist der Autor des IoT/M2M Cookbook und der Ideenträger des akorIoT. akorIoT ist offen für jedes MCU-Kit mit Arduino R3 Header und wurde mit Arduino UNO getestet. Für IoT-Produkte für die Serie passt das akorIoT auf 33 verschiedene STM32 #Nucleo MCU-Evaluierungs-Kits.

Neben den vielen Vorträgen zu NB-IoT waren die kostenfreien Messungen der Antennen durch Triptec und die Live-Vorführungen durch MM1 das High-Light der Veranstaltung. In den Pausen und nach dem Event wurden Erfahrungen auch zwischen den Teilnehmern ausgetauscht. Kopien meines Vortrages zu Design-In von Antennen, Datenblätter zu akorIoT, Antennen und Funkmodulen stelle ich auf Anfrage gerne zur Verfügung - harald.naumann (at)

NB-IoT Hackathon - 23th of June - Berlin, Germany

- Date: Starts June 23 2017 at 8.00am / Ends June 24 2017 at 4.30pm
- Venue: @ hub:raum Winterfeldtstraße 21 10781 Berlin

There will be an NB-IoT #Hackathon in Berlin, Germany. Developers and start-ups are being called to disrupt today’s IoT landscape by creating services & solutions based on the NB-IoT technology.

#NBIoT stands out due to its energy efficiency, low costs, and deep, long-range transmission capabilities. This is a great opportunity to be on the cutting edge of LPWA (low-power wide area) technology and build solutions for the age of #M2M communications.

Are you a developer or start-up working on radio technologies, smart metering, device monitoring, or sensors? If so, you cannot miss this event. Don’t see your area of expertise mentioned? Not to worry, we understand that there is a huge diversity of #IoT applications, so if you are part of the ecosystem sign up now!


1. Smart Buildings
Today buildings are equipped with loads of high-tech equipment for energy control, climate regulation or people transport. A load of these is still unconnected and flat out stupid – this has to change!

2. Smart Metering
Measuring and controlling the flow of energy into and out of a building is a core challenge for the utility industry.

3. Predictive Maintenance
Remote machinery can be painful and money intensive to maintain and operate – especially if something breaks. Knowing when, how and which part is turning into a problem can be vital for frictionless operations.

1st Price Gold Award 7500 € Cash
2nd Price Silver Award 2000 € Cash
3rd Price Bronze Award 500 € Cash

You can't make it but you are keen to make your IoT idea come true? Do not hesitate to ask for an akorIoT radio adapter on NB-IoT with Arduino header or samples for NB-IoT modules for your first PCBs - harald.naumann (at)

World’s first free and open IoT out of the box with #NBIoT module and #Arduino header
Many #IoT / #M2M Cookbook customers asked me for an evaluation kit within the last two years. I launched the first version in September 2016 during M2M Summit. In February 2017 the multi cellular version came true. The working name is HARduino because it has an Arduino R3 compatible UART interface.

HARALD – ALD + duino = HARduino

The Arduino shield will support at first stroke a:
• Quad-band GSM module
• Penta-band UMTS module with fallback to GSM
• LTE-Cat1 module with fallback to UMTS and GSM
• NB-IoT (LTE-Cat-NB1) module
• Combined LTE-Cat-NB1 & LTE Cat-NB1 module

I got my first NB-IoT modules last year. The footprint of the NB-IoT module and the GSM module are the same. Even the AT command set is the same. This means customers can start with a prototype on #GSM or #LTE and migrate to NB-IoT easy.

The Arduino shield comes with:
• Temperature sensor (standard)
• Humidity sensor (option)
• GNSS module (#GPS, #GLONASS, #Galileo, #Beidou) module (Option)
• Automatic MCU voltage detection from 3 Volt to 5 Volt
• eSIM and standard SIM card without SIM look

NB-IoT-LTE-Cat-NB1-M1 for any MCU eval kit:
• Freescale
• Intel Galileo
• Microchip PIC
• Nordic Semi
• STM Nucleo
• and a lot of more

The radio adapter was tested with an Arduino UNO. However, UNO customers are not the target customers. The radio adapters are planned to support IoT customers with IoT products for mass production.

It is world’s first free IoT/M2M out of the box because:
• Free to select the MCU
• Free to select the Compiler
• Free to select the language
• Free to select the IoT portal
• Free to select the SIM card
• Free to select consulter
• Free to select antenna designer

Services around the HARduino adapter:
• Studies with up to prototypes
• Customised HARduinos with other sensors or wireless modules
• Schematic diagram and layout design review
• Development of IoT devices for mass production
• Antenna consulting, antenna matching up to customised antenna designs
• Antenna radiation pattern measurement
Bluetooth LE to cellular gateway on HARduino plus Nordic Semi BLE eval kit:

Are you interested in an HARduino as well? Which versions are you interested in? Which HARduino shall we design next? Do you miss something in the HARduino concept?

And the main question – Is HARduino the right name for the radio adapter? Shall we call it IoTfree or FreelyIoT or FreelYoT? What name do you recommend? What is the recommendation of your marketing team? Thank you in advance for your feedback to harald.naumann (at)
