Taxi cabs, armored cars, buses, and trains may easily benifit from a TETRA system. Using AVL, dispatchers and managers may visually locate vehicles in the field, and make logical decisions to help route traffic, or provide time estimates. TETRA allows for greater automation, however, such as a device to open a gate, or signal the arrival of a vehicle to a designated spot. Using TETRA's data featuers, a train could be setup with a TETRA radio that reports speed and location, allowing for schedules downtrack to be updated with current arrival information. Armored car companies, who often carry attractive amounts of money that needs protection, could have signal information sent to banks and other secure locations, with near realtime communications of the vehicle's security status. SDS messages may be used to send quick text information or status reports.
Shopping malls are a collection of different groups occupying a piece of land. They may be seen as a small community, and they have communications needs. With TETRA's volume of talkgroups, the larger stores could have their own talkgroup, and tie into the mall's employees, such as the security group, maintaince staff, and administration. TETRA's spectrum efficiency would minimize the amount of antennas and required frequencies. Like the mall, educational institutions have diverse communications requirements. With TETRA, the staff may communicate with each other, employees may process work orders, and telephone integration would allow employees to communicate with desk staff using the telephone system. TETRA's data network could be used to track doors, gates, and other physical access controls, but also be involved in data reporting among the buildings with infrastructure intelligence, such as HVAC settings, fire alarm status, and even sump pumps.
Outside the United States, TETRA and Government get along quite well -- TETRA's voice and data neworks are used with police, fire, and military forces across the globe. TETRA was designed in Europe to take care of public safety needs, and even after 15 years, new networks are still being constructed. Different governmental groups can really benefit from TETRA's Dynamic Group feature. With Dynamic Groups, a dispatcher may link different radios into a special group, programmed over the air, to solve a specific communications problem. For example, a traffic accident may involve police and fire units to respond. The dispatcher may link the responding radios into a Dynamic Group, creating an instant communications path for the responding people to use. This action happens over the air in real time. Once the accident is managed, the dispatcher may easily unlink the radios, and the radios return to their previous configuration. Government often demands security. TETRA was born with security in mind, beginning with the mutual authentication algorithms, where the radios and network prove themselves to each other, ensuring that the radio on the network truly belongs there, and has authority to operate. TETRA offers two levels of encryption: Air Interface Encryption (AIE), and End to End Encryption (E2EE). These two technologies may be combined to provide the ultimate in encrypted communications. Sepura has a line of special radio gear of interest to the special forces groups. Please contact us, and we would be happy to show you.
