Capacity of MIMO DSL systems using 100 MHz measured channel data

Abstract

This paper evaluates the capacity of MIMO DSL systems up to 100 MHz using short loops (50 and 200 meters) based on measured channel data. The experimental results show that these systems have capacities as high as 0.77 Gbps for the 50 m loop, for example.

Experimental evaluation of fourth generation DSL in different DSM scenarios

“…Recent works described that this frequency values can achieve 100 MHz [2], [7], [14], even reaching 300 MHz, depending on the used cable quality [7]. Results of capacity simulations showed that this transmission channels can achieve near 1 Gb/s, and the use of DSM techniques to avoid crosstalk effects can help ensuring these data rates [2], [14], [15].…”

Advanced Topics in Measurements

“…A comparison between the fourth generation DSL proposal and older DSL generations, in terms of desirable data rates, transmission bandwidth and typical length of the used copper cable is illustrated in Figure 1. Some initial available works describing the research on the fourth generation broadband over copper can be find in (Acatauassu et al, 2009;Magesacher et al, 2006;Odling et al, 2009;van den Brink, 2010).…”

It is important to notice that the use of FTTH does not necessary mean that fiber is deployed all the way to a point inside the home.…”
