Teradek's latest radio transmission system for professional live productions uses Teradek's Joint Source Channel Coding (JSCC) technology to transmit uncompressed 4K 10-bit 4:2:2 video with a latency of less than 1 millisecond over distances up to 1.5km. Teradek Ranger has a 12G-SDI input, a 12G-SDI loop output and an HDMI 2.0 input. The power comes from either a V-mount or gold-mount battery.
The radio transmission is protected by AES-256 encryption and uses the frequency range from 4.9 GHz to 6.0 GHz and a bandwidth of 40 MHz / 20 MHz. The frequency can be automatically selected or manually set in 5 MHz steps. The Teradek Ranger system has multicast capabilities, i.e. one transmitter can address up to 6 receivers simultaneously. Setup is easily done via the Launchpad (iOS/Android) app - transmitter and receiver can be paired, channel interference monitored and operating frequencies set at the touch of a button.

What is the difference between Teradek's new Ranger and the Bolt radio transmission system?
While both use the same zero-delay technology, Ranger offers a number of improvements for live productions, including an extended frequency range of 4.9 GHz to 6.0 GHz; licensed band operation; H+V antennas that provide better picture quality over longer ranges; N-type connectors on the Ranger TX; and finer manual frequency control.

The cheapest set (transmitter (TX) and receiver (RX)) from Teradek's Ranger (HD) transmits 1080p60 HDR over distances of up to 450 meters and costs about ,000, the 4K (2160p50) HDR version costs about ,000 and transmits about 900 without and 1.5km with the external panel antenna that comes with it. Each version is also available separately (receiver or transmitter) and with V-mount or gold mount.
