Supervectoring

from Wikipedia, the free encyclopedia

In Supervectoring (Supervectoring 35b) is the youngest development of VDSL2 standards. Alternative names are VDSL Annex Q or Vectoring Plus or V Plus. The procedure is  standardized by the  ITU-T under the specified VDSL2 profile 35b (ITU-T G.993.2 Annex Q ).

The VDSL2 and DSL processes use a frequency band on the already laid copper wire pairs in the telephone network that is above that for analog voice telephony or ISDN and therefore cannot be used for these conventional telecommunications applications.

General

Supervectoring (DSL profile 35b) extends the bandwidth used at the end connection from 17  MHz to 35 MHz. The vectoring technology, with which the so-called crosstalk with other fixed network participants is reduced, is also available and has been optimized by supervectoring.

According to the manufacturer Huawei, this technology enables a downstream rate of up to 300 Mbit / s within a radius of 300 meters. Vectoring is a technique in which the existing copper lines from the cable distributor to the house connection can continue to be used.

The equipment is compatible with existing ADSL2 + / VDSL2 / vectoring terminals.

Use in Germany

The German Telekom since August 2018 has Supervectoring with bandwidths of up to 250 Mbit / s downstream (Magenta home XL) and 40 Mbit / s upstream to. In areas in which supervectoring with 250 Mbit / s cannot technically be offered, bandwidths of up to 175 Mbit / s may be available as a fallback option. By October 2019, around 25 million households had the opportunity to use supervectoring, and by the end of 2019 it should be 28 million. Other providers of supervectoring include a. Inexio, Vodafone , DNS: Net and 1 & 1 Telecom GmbH .
