Abstract:
This paper presents an interference analysis considering the impact of GSM uplink signals on passive UHF transponders in accordance of the ISO/IEC 18000-6 standard, both operating in a similar frequency band. The GSM uplink signal (from the mobile device to the base station) is particularly critical as interferer, as the mobile device can be located close to a transponder system e.g. several persons having a phone call close to a subway ticketing system. The measurements were conducted with GSM interferer signals generated by an RF signal generator and a programmable GSM mobile phone. February 17, 2015.
