What is an ip extender?
An IP extender makes it possible to connect one or more workstations to a computer at any distance. Keyboard, screen, mouse, ports, etc. can be used and connected. Even e.g. microphone and cameras.
IP extenders are LAN connected modules that can be used on almost any type of cabling to transparently drive Ethernet communications beyond the IEEE 802.3 species with its limitations in distance around 328 feet or 100 meters.
IP extenders can communicate over longer distances, at higher speeds and between point to point or cluster of IP extenders in a very cost effective way. IP extenders can be seen as network extenders. As LAN extender, Ethernet repeater, CAT5 Extender devices, Ethernet bridge, network bridge and Ethernet cable extender and use a variety of transfer techniques over physical media such as copper or fiber.
Techniques commonly used in the Ethernet extension are: VDSL (very fast DSL), an xDSL technology that provides data and voice transmission up to 52 Mbit / s downstream and 12 Mbit / s upstream. Currently, the standard VDSL uses up to 4 different frequency bands, two for upstream and two for downstream.
A modulation technology by default is either QAM (Quadruple amplitude modulation) or DMT (multivariate modulation) which are not compatible but have similar performance. The most commonly used technology is DMT. VDSL is suitable for applications such as HDTV, as well as telephone services (Voice over IP) and public Internet access via a single connection. A new VDSL standard is now available called VDSL2 which delivers data and voice transmission at a theoretical maximum of 250 Mbit / s with full duplex.
