IoT M2M blog

The home of free hints and tips about wireless IoT / M2M

Thank you

Thank you for contacting us. More about Mr. Harald Naumann here . Our project questions are:

  • Do you have a company profile or website?
  • What is your planned IoT / M2M application?
  •  Do you have prior experience with wireless applications?
  • What will be the estimated quantities in the first, second and third year of mass production?
  • In which countries you would like to sell your product?
  • When do you plan the start the development, to hold the first prototype in your hands and to pass the necessary certifications?
  •  Are you aware of the number and type of certifications you will need and their costs in your target territories?
  • Will the antenna be inside or outside the enclosure?
  • What will be the size of the enclosure or the PCB inside the enclosure?
  • What kind of supply voltage and source do you plan to use (AC, DC, battery inside with charger etc.)
  • Do you need to outsource the development?

Based on your answers to the above questions we will provide a hardware and software concept outline.

For small quantities we prefer concepts utilising connector-based radio modules. For medium to large quantities we prefer SMT mounted radio modules. All components specified will be surface mount to save money and the time and cost of manual work.
If your IoT / M2M device is to be a GPS tracking device then we will need further details. The hardware concepts to track an eagle, a truck, an expensive asset like oil on canvas or a dog are quite different.
If you plan an embedded antenna on a PCB inside a small enclosure, then you will save a lot of money by designing the device around the antenna. The antenna is the key in any wireless application.

Thank you for your time and thank you in advance for your detailed answers. The more detail you can provide, then the more detailed will be our recommendation.
The IoT / M2M Cookbook listed here is a good starting point to guide you and to help you save time and money in development.

  1. Hi

    I’m interested in this book. I’m looking for opportunity to learn how IOT works, how to do my own IOT device.I’m looking for Open Source project to work on IOT


  2. Hi Prathap, you got an email. The book describes in detail how to move from an idea to a IoT device in mass production. If you tell me one to three ideas, then I will make you an proposal. The proposal could contain some open source projects in IoT as well.

  3. Hi Mr. Harald,
    first of all, thanx a lot for giving so much of info.

    Like Prathap and many others, I am also interested in the cookbook.

    I need help in designing GSM & GPS antenna for a vehicle tracking device.

    GSM should be PCB trce on the same board

    The device should be suiting to work in India

    GPS should be again on the same board with a ceramic patch (Using LNA from the module & optional External Active Gps antenna)

    The proto is already made but with lot of deficiencies. Please lt me know if you want more info.

    Thanx again,
    M. Ramdas

  4. Dear Mr. Ramdas, I just give back what I got before. My boss shared 30 years his knowledge with me. I do the same, but I use my blog and my IoT M2M Cookbook for sharing. In the book is a GSM PCB trace antenna public. A lot of readers made a copy to their designs. If you like I can help with the GSM modules and with the GPS modules as well. I also can help with a GPS module with integrated GPS patch antenna and integrated switch to an external active GPS antenna.
    Best regards from Germany to India

  5. Dear Mr.Naumann,

    I’m interested in IoT and I want to study about it.
    Can you send me your IoT / M2M Cookbook ?

    Thanks and best regards,

  6. Hi Me.Harald,
    I am interested in IoT,i want to create my own vehicle based tracking system,could you help me.and could you send your book.

  7. Hi Candru, you will find an offer in your email inbox. I also can help with evaluation kits for prototyping a GPS tracker. At you will find several cellular / GPS radio adapter with Arduino header. The Arduino UNO we use for testing. Prototyping we do on STM32 Nucleo.
    A typical design process:
    Best regards

  8. Hi Harald,

    I am a newbie in this field and I would really like to learn more about IoT, I would like to get a copy of this cookbook, this book would be really great help for me to start with.


  9. Hi, Harald.
    I am interesting in PCB antena design for GPSR and 3G modem.
    We need to pass CE certification with them.

    I would like to buy your IoT M2M Cookbook.


  10. Hi Oleksandr, thank you for your order again. The antenna design you showed to me on PCB get tested by my akorIoT team. It works. The bandwidth is fine. Only the centre frequency is shifted but is maybe okay because we tested without an enclosure.

  11. Hi Harald, I would like to read your book ! Waiting your feedback.

  12. Dear Jeremy, Thank you for your interest. You will find an email with an offer in your inbox. Maybe you are interested in antenna matching or antenna design services:
    If you plan an own wireless IoT product then akorIoT Micro and akorIoT Nano are good and cheap starting points:
    Best regards from Germany

  13. Hi Harald,

  16. Mr. Harold,
    I’m a student working towards an associates degree in electronics engineering. (I’m unsure if I want to take it to a 4 year degree of a bachelors of science in electrical engineering) I absolutely love electronics though. I just finished wiring my father’s mailbox with a reed switch and wifi esp8266-01, to send an email whenever it is opened, the email is then forwarded to a cell in the form of sms. (my pops is getting old)
    I’d love a copy of your book. when I price check wwan lte modems at digikey or mouser its astonishing. I can buy a decent refurbished cell phone for half the price of a 4G-LTE module in the mini pcie ff. The prices are insane.
    So for my prototype I’m just going to use a gpio module connected via usb to a cell phone for M2M.
    I am sure the cookbook contains a wealth of knowledge, and hopefully some insight to a less expensive option when designing for production.

  19. Hi Harald,

    Greetings from India. Appreciate your content on LPWAN and antenna design. I would love to get your ebook.


  20. Hello,
    I have an question. We assume that my new product contain a certificate GSM module and is connected to a PCB antenna designed by me following your advice. In order my device to take a CE certification must be full tested again? My custom antenna will cancel the GSM module certification?

  21. Antanstasios, The CE (RED) certification only applies to the radio module and is not transferred to the complete circuit board with the enclosure. CE +CE <> CE. With a bad antenna with a bad return loss, harmonics can be generated quickly. Also a good chip antenna wrongly integrated, with too small ground plane or with bad platinum layout may lead to harmonics. If you don’t have any experience or measurement equipment (Vector Network Analyser), it is difficult to evaluate a self-made PCB antenna. If the experience is missing then I recommend an external consultant for antennas. A consultation with report often costs only 3 to 4 hours working time and saves thousands of Euros in radio certification.

  22. Hi Mr. Harald,

    Thanks for sharing good info.

    I am interested in the cookbook.

    I need help in designing GSM,GPS and WiFi antenna for a vehicle tracking device and remote monitoring devices.

    GSM should be PCB trace on the same board
    Target area is Indian sub-continent.

    GPS antenna on board with a ceramic patch.


  23. Hi Harald I’m working on remote sensors and wondering about network registration times. The application can sometimes be powered by batteries so time X load is important. I’m wondering if I can get or buy a copy of your latest cookbook. Cheers.

  24. Hi Mr. Naumann,
    I am interesting in PCB antena design.
    I would like to ask you if i could buy a copy of your IoT M2M Cookbook.

    Kind regards

  25. Dear Brian,
    for GSM a few seconds are common but 1 minute is fine as well. With NB-IoT it is up to 10 seconds but a few minutes is fine as well. If the module was registered before then it is much faster. A multimode module a GSM, NB-IoT and LTE-M will search worst case 25 minutes for a network- You have to tweak the module with AT commands to speed up the registration.
    For the IoT M2M Cookbook, you will find an offer in your email inbox.

  26. Dear Vishal,
    You will find an offer in your inbox. GSM and Wifi antenna can made by PCB track. GPS antenna could be a patch or a chip antenna.

  27. Dear Mr. Naumann,

    i would like to ask you if i could get a copy of your IoT M2M Cookbook via E-Mail.
