The new benchmark in LPWA indoor penetration is underground

Estimated LoRaWAN cell size versus cellular BTS in Munich

Light indoor, indoor penetration and deep indoor in LPWAN was yesterday. The new record for the penetration through walls and floors was achieved in Munich on August 10, 2018 with NB-IoT. Due to the great heat in the office, our Munich team continued the NB-IoT tests in the Munich subway tunnel. With NB-IoT you will […]

Antenna matching service

As the question about the costs and the procedure for the matching of antennas frequently occurs, we have described the process and explained it with some examples of projects. To estimate the costs, the answers to the following questions are necessary. Standard questions on antenna matching: Which radio modules were used? How many radio modules […]

November 2018, Munich, Germany Time 17:00 – 18:00 Session/Workshop Speaker: Wilhelm Oelers, Triptec HL UG Language: English Registration: 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 […]
