Multiple loop extenders can be placed on a line, effectively making the reach of the ADSL signal infinite. That is, it is possible to reach any subscriber with any ADSL speed if one uses multiple loop extenders. A repeater can either be an amplifier or a re-generator. Amplifiers increase the signal level of the analog transmission signal; re ...
EarthLink logo from 1998–2015. EarthLink was founded in July 1994 by Sky Dayton when he was 23 years old. [9] Dayton was convinced of the need for a simple, user-friendly dial-up Internet service provider (ISP) after spending an entire week trying to configure his own computer for Internet access. [10]
Most wireless repeaters (or range extenders) are purpose-built, but certain wireless routers can be flashed with custom firmware such as DD-WRT to give them a 'range extender' option. A better option for extending wireless coverage is to configure a secondary box as a wireless access point , with a wired connection between a LAN port on this ...
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. [1] In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
A side effect of the move to the self-install model is that the DSL signal can be degraded, especially if more than 5 voiceband (that is, POTS telephone-like) devices are connected to the line. Once a line has had DSL enabled, the DSL signal is present on all telephone wiring in the building, causing attenuation and echo. A way to circumvent ...
Wireless technologies can be evaluated by a variety of different metrics of which some are described in this entry. Standards can be grouped as follows in increasing range order: Personal area network (PAN) systems are intended for short range communication between devices typically controlled by a single person. Some examples include wireless ...
DSL modems vary in data speed from hundreds of kilobits per second to many megabits, while voice-band modems are nominally 56K modems and actually limited to approximately 50 kbit/s. DSL modems exchange data with only the DSLAM to which they are wired, which in turn connects them to the Internet, while most voice-band modems can dial directly ...
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [ 1 ]
