Hellas Online

Hellas Online's network provides high-capacity connection between its data centres and sites, thus allowing Hellas Online to backhaul high bandwidth cost-effectively to its unbundled local loops, without having to lease capacity from OTE, while in certain cases, enabling Hellas Online to lease its own spare capacity to other Greek or international telecommunications operators.

High-altitude platform

It has gained significant interest because HAPs will be able to deliver bandwidth and capacity similar to a broadband wireless access network (such as WiMAX) while providing a coverage area similar to that of a satellite.

Instant computer support

This was made possible due to the remote software available to the technician that allowed them to remotely connect to any company PC at any time and the fact that the employees’ computers were all on a LAN (Local Area Network) which could provide sufficient bandwidth for a remote connection to function properly.

Interlace

Interlaced video is a technique of doubling the perceived frame rate without consuming extra bandwidth

Internet in Portugal

Taking advantage of the increased bandwidth provided by their ADSL2+ network, Sonaecom announced in June 2006 the launch of their IPTV service, dubbed SmartTV.

InterStream Transit Protocol, a high bandwidth streaming protocol which works across administrative boundaries on the Internet

KDR 444

FM with a bandwidth of 16 kilohertz (25 kHz in Norway) is used.

Kell factor

The Kell factor, named after RCA engineer Raymond D. Kell, is a parameter used to limit the bandwidth of a sampled image signal to avoid the appearance of beat frequency patterns when displaying the image in a discrete display devices, usually taken to be 0.7.

Killersound

In fact, Adobe Systems still features the technique as it now perfectly applies to low-bandwidth audio presentation on mobile devices at Adobe.com.

Lafesta

Lafesta was the first station that adopted the AACV2+ codec, that produce high fidelity, while still minimizing bandwidth consumption.

Magnetic tape

It was the team at Ampex, led by Charles Ginsburg, that made the breakthrough of using a spinning recording head and normal tape speeds to achieve a very high head-to-tape speed that could record and reproduce the high bandwidth signals of video.

Negroponte switch

Cory Doctorow an author and also sometime Electronic Frontier Foundation activist has described the process of the switch as unwiring, which is also a move away from a global internetwork which in reality passes through many chokepoints where data may be controlled and inspected toward one which uses available bandwidth frugally by passing communications in a mesh and avoids chokepoints.

Network operations center

Example organizations that manage this form of NOC includes Artel, a service provider of commercial satellite bandwidth to the United States Department of Defense, located in Herndon, Virginia.

Newisys

Based on the SCSI extended command set and serial interface, the Newisys SA2120 delivers up to 6.0 TB of incremental storage capacity at transfer rates up to 4800MB/second aggregate bandwidth.

PCI eXtensions for Instrumentation

PXI system data bandwidth performance easily exceeds the performance of the older VXI test standard.

Piper, Kansas

These schools will be the first in the nation to have Google Fiber bandwidth accessible for endless possibilities in the realm of education.

Q value

Q factor, a measurement of a resonant system's relative bandwidth

Radio Solar Telescope Network

The USAF/RSTN system is currently being upgraded in frequency to a bandwidth from 25 MHz to 180 MHz by the Solar Radio Spectrometer (SRS) system at Palehua, Hawaii; San Vito dei Normanni, Italy; Sagamore Hill, Massachusetts; and RAAF Learmonth, Western Australia.

Real Time Media Flow Protocol

RTMFP will reduce the bandwidth costs for direct, live, real‐time communication solutions, such as audio and video chat and multi‐player games.

Remote guidance

Given bandwidth issues universally plaguing the healthcare environment imagery beyond still images and brief video has not yet become standard expectation of care environments or PACS systems.

Shannon's law

Shannon–Hartley theorem, any statement defining the theoretical maximum rate at which error-free digits can be transmitted over a bandwidth-limited channel in the presence of noise

ShowEQ

SOE has used a number of encryption techniques to defeat ShowEQ, but because of the enormous bandwidth and latency demands placed on their servers, there is a point of diminishing returns with respect to strong encryption of the EverQuest protocol.

Static random-access memory

The power consumption of SRAM varies widely depending on how frequently it is accessed; it can be as power-hungry as dynamic RAM, when used at high frequencies, and some ICs can consume many watts at full bandwidth.

Systems integrator

One answer is to use a dedicated military communication system, but the bandwidth needed would be astronomical in such a system.

Traffic classification

Peer-to-peer file sharing applications are often designed to use any and all available bandwidth which impacts QoS-sensitive applications (like online gaming) that use comparatively small amounts of bandwidth.

Ultra-wideband

Ultra-wideband (also known as UWB, ultra-wide band and ultraband) is a radio technology pioneered by Robert A. Scholtz and others which may be used at a very low energy level for short-range, high-bandwidth communications using a large portion of the radio spectrum.
