Abstract

Cilj ovoga rada bio je implementirati sustav za višekanalnu bežičnu komunikaciju u stvarnome vremenu, a glavni zahtjev bila je brzina prijenosa od 2 do 3 Mbps. Detaljno su proučene mogućnosti samoga mikrokontrolera ESP32-S2 kao i službenoga frameworka. Implementiran je sustav koji koristi Wi-Fi tehnologiju i TCP protokol pri čemu se sama implementacija sastoji od dva programa: jednoga za poslužitelja mreže, drugoga za klijente. Sustav je analiziran nakon implementacije, a rezultati pokazuju kako je ostvarena i veća brzina prijenosa od tražene te kako stvarna brzina prijenosa ne odskače puno od maksimalne brzine, što znači da nema nepredviđenih, dodatnih zagušenja unutar mreže, odnosno da je sustav poprilično optimalno implementiran.

Abstract (english)

The goal of this paper was to implement a system for multi-channel wireless communication in real time and the main request was the throughput from 2 to 3 Mbps. The possibilities of microcontroller ESP32-S2 as well as official framework were studied in detail. A system that uses Wi-Fi technology and TCP protocol has been implemented and the implementation itself consists of two programs, one for network server and the other for clients. The system was analysed after implementation and the results show that higher througput was achieved than the requested one and that the actual bit rate is not far from the maximum bandwidth, which means that there is no unforeseen, additional congestion within the network, i.e. that the system is quite optimally implemented.
