Next-Gen Smart Radio: Connectivity Beyond the Grid.

The Alervites AT2 is built for users who need more than basic radio communication. It combines reliable 400–480MHz UHF performance with a simple smartphone app, making setup and operation much easier without the need for complex manual programming.

When cellular networks are unavailable, the AT2 lets you send text, voice, images, and your last known location before network loss directly over the radio on the APP. It keeps your team connected even in remote areas where phones alone cannot.

In addition to standard UHF operation for compatibility with other radios, AT2 also offers a dedicated communication mode that works exclusively between AT2 devices on the same channel, helping reduce unwanted interference from other radios.

Compact, rugged, and USB-C rechargeable, the AT2 fits naturally into both everyday use and outdoor environments. Whether you're heading off-grid, coordinating a team, or preparing for emergencies, it keeps communication straightforward and dependable.

QA:

Q: Does it support network intercom functionality via third-party apps like Phone AI, ZELLO, NSPTT, and Totalk?
A: Yes. Android and HarmonyOS support all four applications, while iOS currently does not support ZELLO and Totalk.

Q: How can I send voice, images or text without a cell signal?
A: After pairing with the Ola Radio app via Bluetooth, the AT2 uses radio frequencies to send text, voice, and images directly to other AT2 units—no cellular network required.

Q: How is Digital Mode different from traditional analog radios?
A: Digital Mode enables encrypted communication between AT2 units, helping keep your conversations private and protected from unwanted listeners.

Q: Can the AT2 communicate with other UHF radios?
A: Yes. In analog mode, it works with standard UHF radios within the 400–480MHz range. The built-in frequency copy function lets you quickly match their channels without needing a computer.

Q: Why does it take longer to send images and how can I ensure success?
A: Image transfer via radio takes 15s or more depending on signal strength and file size. For a successful transfer, place the AT2 in an open area, avoid holding the antenna, and re-send if the signal is interrupted.

Q: Can I send multiple messages at once in Off-Grid mode?
A: No, the AT2 supports one message at a time. Please wait for the current transmission to complete before sending the next one to avoid delivery failure.
