The Emergency Services Network (ESN) operates on LTE and it is planned that in the near future, this will replace Airwave for voice function, in addition to providing high-speed mobile broadband data. Sure Antennas' range of ESN ready antennas have been designed with this transition in mind and not only meet the ESN antenna specification but also work fully with the current Airwave network. This means that the vehicles with our antennas installed are future-proofed and will not require the antennas to be changed once the transition goes through. See below our portfolio of high-performance, multi-function ESN vehicle antennas providing: LTE, 5G, 4G, TETRA, GPS and Wi-Fi to emergency service and public safety vehicles.
