A Wireless HDMI Transmitter and Receiver 100m Extender is a device that allows you to transmit high-definition audio and video signals wirelessly from a source (like a Blu-ray player, gaming console, PC, or cable box) to a display (TV, projector, or monitor) located up to 100 meters (approximately 328 feet) away.

Key Features:

• Wireless Transmission: The primary feature is its ability to transmit HDMI signals over a wireless connection, typically using the 5GHz frequency band to minimize interference from other wireless devices (like Wi-Fi routers). Some models may also support 2.4GHz or dual-band operation.
• 100m (328ft) Range: Designed for extended reach, allowing you to place your display far from the source, even in different rooms or large spaces. However, it’s crucial to note that the “100m” range is usually specified for open environments with a clear line of sight. Walls, furniture, and other obstacles can significantly reduce the effective transmission distance.
• High-Definition Video Support: Most 100m wireless HDMI extenders support Full HD 1080p resolution at 60Hz. Some newer or more advanced models might offer 4K resolution support, though this is less common for the 100m range and can introduce higher latency.
• Audio Support: Typically supports various uncompressed audio formats like LPCM 2.0CH (up to 48kHz sampling rate) and may include support for advanced formats like DTS-HD, Dolby TrueHD, DTS, Dolby-AC7, and DSD.
• IR Pass-back (IR Extension): This is a highly valuable feature. It allows you to control your source device (e.g., set-top box, DVD player) from the receiver’s location using its original remote control. An IR blaster cable connects to the transmitter near the source, and an IR receiver cable connects to the receiver near the display.
• Low Latency: While wireless transmission inherently introduces some delay, good quality 100m extenders aim for low latency, often in the range of 120ms to 200ms. This is generally acceptable for movies, TV, and presentations but may not be ideal for fast-paced PC gaming or real-time applications where every millisecond counts. Some advanced models claim even lower latency.
• Plug and Play: Most systems are designed for easy setup, requiring no software installation or complex configuration. You simply connect the transmitter to your HDMI source and the receiver to your display, power them on, and they often pair automatically.
• HDCP Compliance: Supports HDCP (High-bandwidth Digital Content Protection) standards (e.g., HDCP 1.3, HDCP 1.4) to ensure compatibility with copyrighted content.
• Compact Design & Durable Housing: Typically come in compact metal or plastic enclosures for discreet placement and durability.
• One-to-One or One-to-Many: Most standard kits offer a one-to-one connection (one transmitter to one receiver). Some systems, especially in professional settings, may support one-to-many configurations, allowing a single transmitter to broadcast to multiple receivers.
• Local Loop-out (on Transmitter): Some transmitters include an HDMI loop-out port, allowing you to connect a local display directly to the transmitter while also sending the signal wirelessly to the remote receiver. This is useful for monitoring the source locally.

How it Works:

1. Transmitter (TX):
   • Connects to the HDMI output of your source device (e.g., laptop, cable box).
   • Digitizes and compresses the HDMI audio and video signals using a high-performance codec (e.g., H.265).
   • Transmits these compressed signals wirelessly using a radio frequency (typically 5GHz).
   • If IR pass-back is supported, it also receives IR signals from the IR receiver cable and wirelessly sends them to the receiver.
2. Receiver (RX):
   • Receives the wireless audio/video signals from the transmitter.
   • Decompresses the signals.
   • Outputs the high-definition audio and video through its HDMI port to your display.
   • If IR pass-back is supported, it receives the IR signals from the transmitter and outputs them via the IR blaster cable to control the source device.

Common Applications:

• Home Theater and Entertainment:
  • Streaming content from media players, gaming consoles, or cable boxes to a TV or projector in a different room without running long cables.
  • Creating a clutter-free living space by hiding source devices.
• Corporate Meetings and Conferences:
  • Wireless presentations from laptops to large screens or projectors in conference rooms, eliminating the need for messy cables and facilitating quick setup.
    “Bring Your Own Device (BYOD)” environments where multiple participants can wirelessly share their screens.
• Retail Displays and Digital Signage:
  • Transmitting promotional videos or advertisements wirelessly to multiple displays in retail stores, showrooms, or public areas.
• Educational Institutions:
  • Broadcasting video content to multiple screens in classrooms, lecture halls, or auditoriums without complicated wiring.
  • Security and Surveillance Systems:
    • Wirelessly transmitting live camera feeds to a centralized monitoring station, reducing cable deployment costs and complexity.
    • Outdoor Events:
      • Enabling wireless transmission of video content to large screens during outdoor movie nights, concerts, or other events where running cables is impractical.

Important Considerations:

• Obstructions: The 100m range is typically for “line of sight.” Walls (especially concrete or thick ones), metal objects, and other obstructions will significantly reduce the effective transmission distance.
• Interference: While 5GHz is less prone to interference than 2.4GHz, other devices operating on the same frequency band (like powerful Wi-Fi routers) can still cause signal degradation or dropouts.
• Latency for Gaming: For serious gamers, even low latency might be noticeable. Always check product reviews and specifications regarding latency if gaming is a primary use case.
• Resolution and Refresh Rate: Most 100m extenders support 1080p@60Hz. If you require 4K resolution, ensure the product explicitly supports it and be aware of potential limitations on range and latency.
