  2. Maximum transmission unit - Wikipedia

    en.wikipedia.org/wiki/Maximum_transmission_unit

    With the normal untagged Ethernet frame overhead of 18 bytes and the 1500-byte payload, the Ethernet maximum frame size is 1518 bytes. If a 1500-byte IP packet is to be carried over a tagged Ethernet connection, the Ethernet frame maximum size needs to be 1522 bytes due to the larger size of an 802.1Q tagged frame. 802.3ac increases the ...

    en.wikipedia.org/wiki/2.4_GHz_radio_use

    Amateur radio operators can transmit two-way amateur television (and voice) in the 2.4 GHz band—and all ISM frequencies above 902 MHz—with maximum power of 1500 watts in the US if the transmission mode does not include spread spectrum techniques. [17] [18] Other power levels apply per regions.

  4. Transmitter power output - Wikipedia

    en.wikipedia.org/wiki/Transmitter_power_output

    In radio transmission, transmitter power output (TPO) is the actual amount of power (in watts) of radio frequency (RF) energy that a transmitter produces at its output. [1]TPO is a concept related to effective radiated power (ERP), but refers to the power output of a transmitter, without accounting for antenna gain.

  5. Path MTU Discovery - Wikipedia

    en.wikipedia.org/wiki/Path_MTU_Discovery

    Path MTU Discovery (PMTUD) is a standardized technique in computer networking for determining the maximum transmission unit (MTU) size on the network path between two Internet Protocol (IP) hosts, usually with the goal of avoiding IP fragmentation. PMTUD was originally intended for routers in Internet Protocol Version 4 (IPv4). [1]

  6. Dynamic line rating for electric utilities - Wikipedia

    en.wikipedia.org/wiki/Dynamic_line_rating_for...

    Dynamic line rating (DLR), also known as real-time thermal rating (RTTR), is an electric power transmission operation philosophy aiming at maximizing load, when environmental conditions allow it, without compromising safety.

    High-frequency Active Auroral Research Program maximum power output, the most powerful shortwave station in 2012 80 dBm: 100 kW: Typical transmission power of FM radio station with 50-kilometre (31 mi) range 62 dBm: 1.588 kW: 1.5 kW is the maximum legal power output of a US ham radio station. [12] 60 dBm: 1 kW = 1,000 W

  8. MTU - Wikipedia

    Maximum transmission unit, the size of the largest packet that a network protocol can transmit; Metric ton unit, in metals trading; Mobile Testing Unit, for COVID-19 in England, by NHS Test and Trace; Migrants' Trade Union in Korea, represents foreign workers in South Korea

  9. Power rating - Wikipedia

    en.wikipedia.org/wiki/Power_rating

    The maximum power measured is the nominal power of the module in Watts. Colloquially, this is also written as "W p"; this format is colloquial as it is outside the standard by adding suffixes to standardized units. The nominal power divided by the light power that falls on the module (area x 1000 W/m 2) is the efficiency.
