Nearly a billion exist worldwide, reliably enabling communication from nearly any point on Earth with any other point, with wireless versions completing the coverage to ubiquity. The television, computer,(More)
Home networking (HN) technologies [1] were first introduced in the late 1990s to provide standard Ethernet connections in a residence without rewiring the house with Cat-5 cable. Today several HN technologies are available to the consumer; of them wireless local area networks (WLANs) based on the IEEE 802.11 standard are the most popular. However, WLANs(More)
Modern life increasingly depends on faster Internet access for applications such as email, voice, information search, and a variety of social interconnections, while IPTV is increasing Internet video use. Growing wireless connectivity will substantially increase access bandwidth demand over the next decade. Figure 1 shows digital subscriber line (DSL)(More)
Accurate upstream power back-off (PBO) parameters are needed by operators deploying very high-speed digital subscriber line (VDSL) modems. Although a standardized PBO method for VDSL exist, the standard gives little or no guidance to an operator how to establish these optimized PBO parameters for its particular network and customers. In this paper, we(More)
This contribution describes some specifics of VDSL performance in the presence of bridged taps. It is shown that the effect of a bridged tap depends on both the length and allocation of the bridged tap due to dominating of FEXT. As a result, bridged taps affect the opposite transmission directions differently and usually the upstream performance is degraded(More)
