    Teradek – owned by the Vitec Group (Creative Solutions unit) – are well known for their Cinema, IP Video and Networking transmission products such as the ACE, Bolt, and Bolt 4K series have recently released their new Ranger < 1 ms delay 4K wireless video solution with approx. 1.500m (5.000 ft.) range and 10-Bit 4:2:2 picture quality at 2160p60 resolution for live productions. The set includes TX and RX units and starts from $6,990.00.

    Teradek Ranger – Prominent Features

    Teradek claims that the Ranger holds the title to be the world’s first wireless solution able to transmit 4K HDR video streams with (almost) zero delay (< 1 ms) and a maximum range of 1.500m. The latter is the maximum distance covered without obstacles in the way which usually describes the maximum range within the line of sight. The operating range of the transmitter and receiver is from 4.9 to 6.0 GHz, while users have to especially abide by rules and regulations within licensed frequencies, of course: 4.850 ~ 5.150 GHz, 5.350 ~ 5.470 GHz, and 5.850 ~ 5.925 GHz). Precise adjustment within the spectrum is achievable through tuning steps of 5 MHz.
    With Teradek’s own patented Joint Source Channel Coding (JSCC) Technology, the Ranger transmits uncompressed 4K HDR video. At the same time, AES-256 bit encryption utilizing RSA-1024 bit key pairing secures the transmission immensely. Besides, the signal may be received by up to 6 receivers with only one transmitter, which underlines the product’s multicast-capability.

    Another easy-to-use feature is the smartphone app Launchpad from Teradek, which is available in the App Store and on Google Play. This phone app empowers the production team with cableless control functionality to set up, initialize pairing of devices, check interferences across the channel, or take care of other elements of the workflow such as selecting the primary operation frequency.
    Of course, this is an optional choice since the user may still choose to control the menu via joystick navigation and OLED display on the side of the product body. The other inputs, outputs, controls, and connection options are depicted clearly with the following illustration. Of course, a 12G-SDI input, and a looping output are together at the heart and soul of the product. As usual, V-mount or Gold Mount battery on the backside of the device, which powers the whole camera typically also power such transmission products directly or indirectly. In this case, a 6-28V DC power connection is available with a 2-pin Lemo connector.

    Differences between Teradek Bolt 4K and Teradek Ranger

    A lot of filmmaking professionals might be even more familiar with the Teradek Bolt or Bolt 4K products. They also might wonder, where the difference is between their Teradek Bolt 4K MAX (with 12G-SDI & HDMI 2.0 (In/Out) enabled, DCI-4K resolution with 10-Bit (4:2:2) at up to 60 fps, unlimited receivers and the same 1.500m line of sight transmission distance) and the Ranger.
    Both products are relying heavily on the same < 1 ms delay technology but the Ranger suits live productions profoundly in several distinct ways. While Bolt 4K doesn’t support licensed bands, Ranger does. The Ranger transmitter also coms with N-type connectors. The control dial is more precise for highly accurate frequency control. The H+V (polarised V and H) antennae of the Ranger are substantially different since they are supporting even better picture quality over larger distances which is more valuable for live production than monitoring on set.
