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 […]

BG95 / BG77 antenna selection and antenna matching

LPWA frequencies in comparison

In order to save development and approval costs, the antenna, frequency bands, ground plane size and housing should be carefully designed at the beginning of development. If the company lacks in-house experience with radio, antennas and worldwide approval, we recommend consulting an external consultant. The following text is intended to make you think. I use […]

The LPWAN game changer – 1 Euro per SIM card and year

1 Euro per SIM and year

The Germans are the masters of long words and long sentences with the verb at the end (frustrating simultaneous translators the world over). German datasheets are 30% longer, or in a font size so small they are hard to read.  But, Germans are capable of short stories as well. To cut a long story short, […]

Clever SW stack on LoRa modules in Lower Saxony – Germany

LoRa PCBs

The LoRaWAN software stack is based on plain Aloha. Plain Aloha is a model that describes the typical package loss due to collisions of uplink transmissions in an unsynchronised communication system. With a LoRaWAN system, the model shows 82% package loss at maximum throughput. On top of this we get additional package loss during LoRaWAN […]

Internet of Things Case Study – Smart Parking

Internet of Things Case Study – Smart Parking – “Telemoritz” in Hanover

In Patras, Greece, developers are already working on a smart city technology development using NB-IoT. But how can they avoid the need for a SIM card and its subscription? Let’s consider the technical proposition. Technical needs Smart parking sensors are sending one status update message of 10 bytes two to eight times per hour. 30 […]

NB-IoT live in major German cities

NB-IoT-module on Arduimo shield

Deutsche Telekom AG has its NB-IoT network live in several major German cities (Berlin, Bochum, Bonn, Chemnitz, Dortmund, Duisburg, Düsseldorf, Erfurt, Essen, Gelsenkirchen, Cologne, Leipzig, Leverkusen and Mannheim. There are now no longer any obstacles to developing and using NB-IoT applications. akorIoT with NB-IoT + one of 33 STM32 Nucleo or Arduino UNO = your […]
