Key Features

Uncompressed 4K video – Delivers HDMI video up to 4K@60Hz 4:4:4 with an 18 Gbps bandwidth, preserving full image detail and color for demanding AV and KVM applications.​

 

50 m wireless range – Transmits video, keyboard, mouse, and control signals up to 50 meters (164 feet) through walls using the 5 GHz wireless band, eliminating long cable runs.​

 

Low-latency KVM – Provides approximately 120–180 ms latency at 4K60 and 70–120 ms at 1080p60, enabling responsive real-time KVM operation for control rooms and live environments.​

 

Local HDMI monitoring – The transmitter’s HDMI loop-out port lets users connect a local display for real-time monitoring near the source without impacting the wireless link.​

 

USB 1.1 and IR control – Integrated USB 1.1 extension supports keyboard, mouse, or webcam devices, while IR pass-through enables remote control of the source from the display end.​

 

Multi-receiver mirroring – Supports pairing with up to four additional wireless receivers (GF-EXT-WiK-5G-RX) to mirror the same source across multiple remote displays.

How It Works

The system consists of a wireless transmitter and receiver pair: the transmitter connects to the HDMI source and USB host, while the receiver sits at the display location with USB ports for keyboard, mouse, or other USB 1.1 peripherals.​


The transmitter also offers an HDMI loop-out for local monitoring, and both units include LEDs and channel select controls to simplify setup and status checking.​

 

Once powered, the transmitter and receiver establish a secure 5 GHz wireless link that carries uncompressed 4K@60Hz video along with USB and control data up to 50 m, even through typical interior walls.​
 

Low-latency processing maintains smooth motion and responsive cursor control, making the link feel similar to a direct cable connection in everyday use.​

 

At the remote end, the receiver outputs HDMI to the display and passes USB and IR signals back to the source, allowing users to operate connected systems as if they were local.​
 

For larger spaces, additional receivers can be paired to mirror the same content to multiple displays, all while remaining manageable via firmware updates and installer-focused hardware accessories.

Ideal for...

Corporate AV – Boardrooms, huddle rooms, and training spaces that need to link a rack-mounted or in-room source to a distant display without opening walls or installing new HDMI and USB runs.​

Education & training – Classrooms, lecture halls, and labs where instructors move between podiums or carts but still require reliable 4K presentation and responsive keyboard/mouse control at the display.​

Control rooms – Operations centers, NOCs, and security suites that keep noisy, heat-generating systems in an equipment room while operators work at quiet, wireless-connected workstations.​

Home entertainment – Living rooms, media rooms, and small residential theaters where a source in a cabinet or adjacent room must feed a TV or projector up to 50 m away without visible cable runs.​

Event & staging – Temporary AV setups in conference venues, houses of worship, and rental events where clean cable routing is challenging and quick strike/restore is critical.​

Multi-display mirroring – Digital signage, overflow spaces, or lecture spill-over rooms where one source needs to be wirelessly mirrored to multiple screens using additional GF-EXT-WiK-5G-RX receivers.​

 

Problems It Solves

  • No conduit or cable path – Eliminates the need to open walls, core drill floors, or install new conduit in finished spaces by sending uncompressed 4K@60Hz video and KVM over a 5 GHz wireless link up to 50 m.​
  • HDMI/USB distance limits – Overcomes the short reach of standard HDMI and USB 1.1 cables while preserving image quality and responsive keyboard/mouse performance for real-time KVM operation.​
