    HDBaseT connectors at a presentation and collaboration system from WolfVision. HDBaseT is a consumer electronic (CE) and commercial connectivity standard for transmission of uncompressed ultra-high-definition video, digital audio, DC power, Ethernet, USB 2.0, and other control communication (such as RS-232 and Consumer IR) over a single category cable (Cat 5e or better) up to 100 m (328 ft) in ...

  4. Signal strength in telecommunications - Wikipedia

    en.wikipedia.org/wiki/Signal_strength_in...

    The electric field strength at a specific point can be determined from the power delivered to the transmitting antenna, its geometry and radiation resistance. Consider the case of a center-fed half-wave dipole antenna in free space, where the total length L is equal to one half wavelength (λ/2). If constructed from thin conductors, the current ...

    en.wikipedia.org/wiki/Long-range_Wi-Fi

    Commonly known as "range extender amplifiers" these small devices usually supply around 1 ⁄ 2 watt of power to the antenna. Such amplifiers may give more than five times the range to an existing network. Every 3 dB gain doubles the effective output power. An antenna receiving 1 watt of power, and 6 dB gain would have an effective power of 4 ...

    en.wikipedia.org/wiki/Coaxial_cable

    Ingress is the passage of an outside signal into the cable and can result in noise and disruption of the desired signal. Egress is the passage of signal intended to remain within the cable into the outside world and can result in a weaker signal at the end of the cable and radio frequency interference to nearby devices. Severe leakage usually ...
