Teradek’s new Ranger 4K is claimed to be the world’s first zero-delay (< 1ms) 4K HDR wireless video system for live production.


Teradek: The new Ranger transmitter is designed for live production

It is claimed to offer “best-in-class performance in challenging RF conditions”, with a wide operating range from 4.9GHz to 6.0GHz, and a range of up to 1500m (line of sight).

It offers secure video transmission using AES-256 encryption with RSA 1024 key pairing and is multicast-capable supplying up to six receivers at once.

It can carry uncompressed 4K HDR 10-bit, 4:2:2 video, using patented JSCC (Joint Source Channel Coding) technology, that utilises MIMO (Multiple Input, Multiple Output) transmission and OFDM (Orthogonal Frequency Division Multiplexing) modulation. Users can choose the system’s operating frequencies from 4.9 to 6.0GHz, in both licensed and unlicensed frequencies, with 5MHz fine tuning intervals.

Ranger’s RF design is U-NII-5 ready (for Unlicensed National Information Infrastructure devices in the 5GHz band) and is claimed to utilise 40MHz or 20MHz channels with far greater efficiency than H.264/HEVC encoding, with better performance in the noisiest environments.

The transmitter can be used between a camera body and either V-Mount or AB Gold Mount battery – it has a 6-28v DC power input. It also has 12G-SDI input and 12G-SDI looping output, as well as HDMI 2.0 input. Also on the side of the body are a small OLED screen with joystick navigation button, and status lights.

Ranger RX can use two different antenna configurations, either a combination of horizontal and vertical antennas, or a panel antenna. The panel antenna gives it a longer range and more robust connection but is directional, while the H+V antennas are shorter range but omni-directional.

The system can be configured using a smartphone, using its Launchpad app for iOS or Android. This allows users to pair transmitters and receivers with the touch of a button, monitor channel interference, set operating frequencies and control cameras directly from the app.

The TX RX set costs from $6990 (for the HD-only Ranger HD with limited 460m range), while the Ranger 4K, which supports signals of up to 4K 60p, costs $14,990.
