Tracking indoor and outdoor by GNSS and cell ID

Tracking test: Main trip to Amsterdam

Field test: tracking indoor and outdoor In order to demonstrate the tracking goods and assets across borders, a field test was executed over several days in different countries and different methods of transport. In addition to delivery vehicles and cars, trams and walking were also used. The car was parked in an underground car park […]

NB-IoT for smart bin / intellegent container

akorIoT SensPRO - NB-IoT , LTE-M, GPRS reference design

Enquiry for a smart waste container We have already developed many antennas for metal containers on GSM, UMTS, NB-IoT, LTE-M, LoRaWAN and Sigfox. For us the radio technology does not make a big difference. The akorIoT SensPRO is already a reference design for such a smart bin. Request for the smart waste bin Hi Harald, […]

How your wireless IoT idea can become a real product The Timeline: May 2018: Inquiry Tracker with harald.naumann (at) lte-modem.com February 2019: Order for development with akorIoT Group August 2019: Pre-series/ field test order with akorIoT Group Basis = akorIoT SensPRO http://www.gsm-modem.de/M2M/m2m-componets/akoriot-senspro-reference-design-nbiot-ltem/ Radio modules = Quectel BG96 Multimode NB-IoT, LTEM, GSM GNSS Module= Quectel L76L, […]

Why to use NB-IoT instead of LoRaWAN or Sigfox?

Why NB-IoT instead or LoRaWAN and Sigfox

Why now NB-IoT instead of LoRaWAN or Sigfox? There are hundreds of reasons for NB-IoT and hundreds against LoRaWAN and Sigfox. Below is a typical example. The potential customer already prefers NB-IoT and we can deliver NB-IoT with fallback to GSM. In Germany there is no Sigfox Indoor in my city. In the three neighbouring […]

IoT M2M Cookbook – The outlook for embedded antenna design

GSM PCB antenna simulation

The IoT M2M Cookbook contains a simulation of a dual F antenna for cellular. This antenna has been customized several times by customers, or by us on behalf of customers. The Gillette order button using this base design and described in the book supports NB-IoT, LTE-M and GSM from about 750 MHz with 960 MHz […]

NB-IoT and Sigfox comparison – number of operators in Germany and the States

Cellular operators versus Sigfox in US

In order to minimize the risk, the developers of IoT devices try to avoid single source components and services. For microcontrollers and radio modules it becomes difficult, but mostly similar components from different manufacturers are used. The LPWAN technology has to be chosen sooner or later. NB-IoT and LTE-M are offered by different network operators […]
