Thermal Stress in Modern Public Safety RF Sites High duty cycle LMR sites increasingly operate inside shared RF environments that combine P25 trunked systems, conventional mutual aid channels, utility radio systems, microwave equipment, and broadband public safety services. The result is a higher continuous RF load on passive infrastructure than many legacy sites were originally […]
