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 […]

From concept to your wireless IoT button

IoT button

The akorIoT Group has a development team with many years of experience in wireless data transmission which today this is termed “Wireless IoT”.  The integration of antennas into enclosures is another area of expertise for the akorIoT Group; in addition to standard antennas such as solderable chip antennas or flex PCB antennas, customer-specific antennas are […]

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 […]

Antenna Return Loss by VNA

Antenna Return Loss by VNA

The upper left graph illustrates the measurement of a filter with two ports at the Vector Network Analyser (VNA). Port 1 is feeding the device under test and is measuring the reflection. Port 2 is measuring the received energy. The lower right graph is showing a typical return loss measurement of an antenna. Has this […]

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 […]
