Antenna gain and beam angle

Antenna gain and beam angle

Parameters of antennas In addition to the mechanical dimensions and the type of connection, data sheets for antennas specify various electrical and physical parameters. 1. Antenna gain The antenna gain is a relative quantity that refers to a reference antenna. The reference value is the receiving field strength of the selected antenna in receiving direction […]

What is akorIoT?

akorIoT Micro & Nano was world’s first NB-IoT adapter with the freedom to select other cellular radios out of a range of modules without a SIM lock. You can also select any MCU kit with an Arduino compatible R3  or Nano expansion slot.  “akor” is the Proto-Celtic word for “open” akorIoT was the world’s first […]

LPWAN antenna designs, testing and consulting – NB-IoT, LTE-M, LTE, GSM, GPS, LoRa, SIGFOX

Antenna reference customers 1

Slide 7, 8 and 9 from our lecture “Self Made Embedded Antenna Design versus Chip Antenna” The following applications are representative of those adopted by many of our satisfied customers. We are not yet authorized to show some of them, but we will reveal more details in due course, and many applications will become public […]

Unlicensed like Icarus flying to the sun or licensed like Charon in the underground

LPWAN - flying to the sun

Icarus wanted to go high up unlicensed. If you don’t follow the rules like Icarus, then the fall comes after the flight. Icarus melted the wings. Why do the unlicensed LPWA companies of all firms repeatedly report hot-air balloons or weather balloons with extreme ranges and fly towards the sky and the sun? Up there […]

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 […]
