Radio systems for wireless access

Diplomsko delo zajema podrobnejšo analizo komunikacije pri radijski sistemih za brezžični dostop med bralnikom in odzivnikom. Na konkretnem primeru je predstavljena komunikacija po standardu ISO/IEC 14443A. Radijski sistem za brezžični dostop zajema bralnik MIFARE MFRC522 in odzivnik MF1ICS50, ki smo ju v nadaljevanju uporabili za odklepanje ter zaklepanje vrat. Pri tem smo uporabili dodatni mikro krmilnik in servo motor. Programsko opremo smo razvili v okolju Arduino na platformi Arduino Uno, ki temelji na mikro krmilniku ATMega 328.Graduation thesis includes a detailed analysis of the communication in radio systems for wireless access between the reader and the transponder. On a concrete example is presented communication by ICO/IEC14443A standard. Radio systems for wireless access comprise a MIFARE MFRC522 reader and MF1ICS50 transponder, which we hereafter used to unlock and lock the door. We used an additional microcontroller and servo motor. The software was developed in an environment Arduino on the platform Arduino Uno, which is based on ATmega 328 microcontroller
