An Ethernetextender also network extender or LAN extender is any device used to extend an Ethernet or network segment beyond its inherent distance limitation which is approximately Convert 100 m for most common forms of twisted pair Ethernet . These devices employ a variety of transmission technologies and physical media wireless, copper wire, fiber optic cable, coaxial cable . The extender forwards traffic between LAN s transparent to higher network layer Communications protocol protocols over distances that far exceed the limitations of standard Ethernet. Options Extenders that use copper wire include 2 and 4 wire variants using unconditioned copper wiring to extend a LAN s. Network extenders use various methods line encodings , such as TC PAM , 2B1Q or Discrete multitone modulation DMT , to transmit information. While transmitting over copper wire does not allow for the speeds that fiber optic transmission does, it allows the use of existing voice grade copper or CCTV coaxial cable wiring. Copper based Ethernet extenders must be used on unconditioned wire without load coil s , such as unused twisted pairs and alarm circuit s. Connecting a private LAN between buildings or more distant locations is a challenge. Wi Fi requires a clear line of sight, special antennas, and is subject to weather. If the buildings are within 100m, a normal Ethernet cable segment can be used, with due consideration of potential grounding problems between the locations. Up to 200m, it may be possible to set up an ordinary Ethernet bridge or router in the middle, if power and weather protection can be arranged. Fiber optic connection is ideal, allowing connections of over a km and high speeds with no electrical ...

Later the coaxial cables were replaced by twisted pair and optical fiber fiber optic links in conjunction with Ethernet hub hubs or Ethernet switch switches . Data rates were periodically increased from the original 10 megabits per second, to 100 gigabits per second. Since its commercial release, Ethernet has retained a good degree of compatibility.

Unreferenced date July 2008 In broadcast engineering , a frequency extender is an Electronics electronic Information appliance device that allows high fidelity analog signal analog ue sound reproduction audio to be sent over regular Plain old telephone service POTS telephone line s, without the loss of higher audio frequencies Treble sound treble . It is an extended concept of a telephone hybrid . The concept uses frequency shifting to overcome the narrowband narrow Bandwidth signal processing bandwidth of regular telephone systems. The input Signalling telecommunication signal is sent on one telephone line as is, or in some cases upshifted to provide extra low frequency response, and sent on a second line shifted down by 3 kHz , which is normally the upper bandpass limit in telephony. Thus, an audio frequency of 5 kHz is sent at 2 kHz. A receiver on the other end then shifts the second line back up and audio mixing recorded music mixes it with the first. This results in greatly improved audio, adding a full octave of range, and pushing the total bandpass to 6 kHz. The sound is then acceptable for Human voice voice , if not for music . It is also possible to add other lines, each increasing the bandpass by another 3 kHz. However, the Diminishing returns law of diminishing returns takes over, because each successive octave is double the size of the last. A third line pushes the bandpass up 50 to 9 kHz, equivalent to AM radio . A fourth line would push it up 33 to 12 kHz. FM radio quality would require five telephone lines to be installed, pushing the bandpass up 25 to 15 kHz. The audio is shifted down by 6,9, and 12 kHz respectively for each additional line. Frequency extenders have been nearly eliminated by POTS codec s. See also telephone hybrid remote broadcast Category broadcast engineering Category telephony ... more details

Ethernet Exchange is a physical network infrastructure through which Ethernet service providers, carriers and Internet service providers exchange Ethernet traffic between their networks. The Ethernet exchange was created as a neutral meeting place where wireless carriers can connect to multiple Ethernet services in several markets that need access to specific locations though one connection. As service providers and operators continue to grow, they need a network to support the increasing amount of Data and video on mobile networks. Thus, allowing Ethernet sellers connecting to an Ethernet exchange immediate access to the buyers and a more basic technical process. Ethernet exchanges offer an accelerated system for carriers and worldwide service providers to extend market reach and coverage. Many carriers and service providers have adopted this technology due to the refined administration features and lower costs when compared to older wholesale Ethernet interconnectivity solutions.
