Embedded antenna design – Make or buy – Wireless Congress in Munich

PCB track antenna simulation

Wireless Congress: Systems & Applications 15th. November 2018, Munich, Germany Time: 16:00 – 17:00 Session/Workshop Speaker: Harald Naumann, tekmodul Language: English Registration: https://www.wireless-congress.com/home.html The wireless Internet of Things has a need for inexpensive wireless modules and antennas. An NB-IoT module will cost less than US$ 6 for a 1K unit order. A self-made NB-IoT antenna […]

Make your hands dirty on NB-IoT application – Wireless Congress in Munich

NB-IoT, locating by TDOA

Wireless Congress: Systems & Applications 14. November 2018, Munich, Germany Time 17:00 – 18:00 Session/Workshop Speaker: Wilhelm Oelers, Triptec HL UG Language: English Registration: https://www.wireless-congress.com/home.html Get your hands dirty with an NB-IoT application NB-IoT is the new shining constellation on the LPWAN sky. It stars are called low energy consumption, low price, small sized and […]

akorIoT Nano with Arduino Nano / STM32 Nucleo 32 and NB-IoT, GSM and GNSS module

NB-IoT / GSM eval kit with Arduino Nano or STM32 Nucleo 32

NB-IoT reference design in credit card size including PCB track antenna The wireless IoT market is crying for small mobile devices transmitting for years from tiny batteries. With akorIoT Nano we developed the next open design.  “akor” is the Proto-Celtic word for “open”. With placing the order for akorIoT Nano you get the schematic diagrams, […]

Comparison of TX energy consumption across LPWAN in EU 12 bytes on NB-IoT, LoRaWAN, SIGFOX and GSM/SMS)

Energy / power consumption SMS versus NB-IoT, LoRaWAN and SIGFOX

After comparing NB-IoT, LoRaWAN and SIGFOX’s energy consumptions during transmission in the USA and Europe, here is another direct comparison with GSM and SMS. SIGFOX and LoRaWAN repeatedly call out their low energy consumption when compared to SMS with wake-up and registration on the GSM network. Their commentary is that the two unlicensed LPWAN technologies […]

Comparison of TX energy consumption across LPWAN in US (12 bytes on NB-IoT, LoRaWAN, SIGFOX))

LPWAN link budget - NB-IoT, LoRaWAN, SIGFOX

The physics in US is the same than in Europe. The energy consumption of a radio transmitter is computed by multiplying the power output with time. LPWAN in the unlicend band in the US  has not to follow a duty cycle but a maximum time of 400 ms per data package plus frequency happing. The […]

Comparison of TX energy consumption across LPWAN in EU (12 bytes on SIGFOX, LoRaWAN, NB-IoT)

Comparision energy ( power) consumption LPWAN -Comparision Energy ( power) consumption @ TX LPWAN - NB-IoT, LoRaWAN, SIGFOX

The energy consumption of a radio transmitter is computed by multiplying the power output with time. The graph clearly shows the envelope of various LPWA transmitters in Europe over time. In Europe SIGFOX and LoRaWAN are limited to 14 dBm TX power. SIGFOX and NB-IoT are along the right scale of time axis. However, in […]

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, […]

How to achiev a redesign from unlicensed LPWAN to NB-IoT and back? – A basic idea

Direction in LPWAN

How do you achieve a redesign from BLE/WiFi to unlicensed LPWAN or NB-IoT? What are the pitfalls you might encounter during the redesign? Why can you not use any old antenna to do the job? What you have to know to pass radio certification in different regions? The unlicensed SubGHz bands in Europe, US, Australia, […]
