RFID antennas enhance public transportation by enabling contactless ticketing, smart card validation, and passenger flow monitoring. They improve efficiency, reduce fare evasion, and provide valuable data for transit operators to optimize schedules and resource allocation.

Why is airport 5G coverage so difficult? Modern airports are challenging RF environments due to massive passenger density, complex metal architectures, and severe interference risks. Reliable airport 5G coverage requires specialized antenna systems with ultra-low passive intermodulation (PIM) ratings for indoor terminals and precise pattern control for outdoor airfield sectors.
