NB-IoT and Sigfox comparison – number of base stations / gateways

In order to understand why more base stations automatically represent a better network, some explanations are necessary. Sigfox has planned 2400 gateways for Germany. These 2400 gateways are confronted with 24,000 LTE base stations from Vodafone and approximately the same amount from Deutsche Telekom. These 48,000 LTE base stations do not all need to be […]

How to calculate the link budget in LPWAN

How to calculate the link budget

The link budget is the total of all losses and gains from the transmission of a radio wave. A wave is amplified or attenuated by the antenna.  During the transmission of a signal between transmitter and receiver, data can be lost. The study of losses and gains is therefore important to calculate the reliability and […]

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 new benchmark in LPWA indoor penetration is underground

Estimated LoRaWAN cell size versus cellular BTS in Munich

Light indoor, indoor penetration and deep indoor with LPWAN is yesterday’s news. 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 tunnels. With NB-IoT you […]
