Reliable and efficient communications is the key to success in all mission-critical operations. Disparate or incompatible communications equipment between public safety agencies can hinder responses to emergencies and result in unnecessary loss of lives and property. ST Engineering’s Integrated Communications Systems seamlessly integrate disparate wired and wireless communications systems to create a unified communications network for both fixed and mobile communications centres, providing seamless and reliable connectivity among public safety agencies to enhance situation awareness and information sharing.
