Today, it is increasingly modern to use wireless transmissions in production. It is
possible to send information messages, control messages and it is often possible to access the
technologies as IoT (the Internet of Things). The aim of this work was to find out which of the
selected Wi-Fi frequencies is more suitable for use in syrup processing equipment. The evaluation
was performed on the basis of attenuation and download speed at each frequency (2.4 GHz and
5 GHz bandwidth). These frequencies have been chosen due to their massive deployment for wifi networks that currently dominate wireless communications. Measurements were made
downloading files on different frequency bands. Mean and maximum data throughput and signal
strengths were also measured. By measuring, it has been found that when using 2.4 GHz wireless
Wi-Fi technology, you can very often encounter strong interference effects. Despite the
theoretically worse 5 GHz frequency spread, you can achieve up to 30% better data throughput
on average. The results show the suitability of 2.4 and 5 GHz Wi-Fi technology. The main finding
is that, despite the worse frequency spread of 5 GHz, it is more appropriate. Not only due to speed
but also in the future due to better transmission capacities and future channel expansion.
