repeater

1. Electrical engineering a device that amplifies or augments incoming electrical signals and retransmits them, thus compensating for transmission losses
2. Nautical one of three signal flags hoisted with others to indicate that one of the top three is to be repeated

repeater

[ri′pēd·ər]
(electricity)
(electronics)
An amplifier or other device that receives weak signals and delivers corresponding stronger signals with or without reshaping of waveforms; may be either a one-way or two-way repeater. Also known as regenerator.
An indicator that shows the same information as is shown on a master indicator. Also known as remote indicator.

repeater

(networking, communications)
A network or communications device which propagates electrical signals from one cable to another, amplifying them to restore them to full strength in the process. Repeaters are used to counter the attenuation which occurs when signals travel long distances (e.g. across an ocean).

A network repeater is less intelligent than a bridge, gateway or router since it works at the physical layer.

repeater

(1) A communications device that amplifies (analog) or regenerates (digital) the data signal in order to extend the transmission distance. Available for both electronic and optical signals, repeaters are used extensively in long distance transmission. They are also used to tie two LANs of the same type together. Repeaters work at layer 1 of the OSI model. See bridge and router.

(2) The term may also refer to a multiport repeater, which is a hub in a 10Base-T network.

Although standard bursts may originate from far outside our galaxy and differ in several other ways from repeaters, some researchers theorize that neutron stars might explain both phenomena.
Already, Powerwave's in-train repeaters are on the "fast track" to deployment; the first commuters to take advantage of uninterrupted wireless connectivity delivered via Powerwave's new in-train repeaters are those travelling on Gardermobanen in Norway, a 60-kilometer high speed rail line between Oslo Central Station and Oslo Airport-Gardermoen.
Repeaters should be used everywhere else, since any jitter transferring through the repeater is low frequency and benign to downstream devices.
The new plant will also deploy the in-house developed repeater integration processes, equipment, and facilities incorporating the industry standard UJTM cable jointing solutions which are firmly built into the repeater and branching unit designs.
The MRC-200 is an advanced Tactical Repeater System (TRS) used in conjunction with modern multi-band, multi-mission handheld radio systems, and supports 20-Watt, 2-Frequency Simplex operations across the 30-512-MHz band according to role and mission.
Leveraging Powerwave's advanced multi-band, multi-operator repeater technology, used by Powerwave's Coverage Systems Innovations team in the deployment of cost-effective, seamless wireless coverage systems for airports, railway stations, tunnels, convention centers, canyons and other environments around the globe where structures or natural obstructions interfere with signals, this next-generation Railway Coverage System is designed specifically for use on board trains, where poor radio coverage prevents passengers from accessing commercial voice and data services.
The test system was designed to reduce the interoperability problems encountered in the field, especially when repeaters are inserted into an HDMI path.
