Combine the immense cost of deploying widespread fibre services with the fact that copper still comprises around 60 per cent of the global market and it is little wonder that plans to upgrade existing copper-based networks are being put on hold or abandoned.
While the ever growing demand for bandwidth remains, the approach to delivering superfast broadband Internet on mass is changing as governments and Internet Service Providers (ISPs) worldwide rethink plans to replace copper with fibre. Vectored VDSL (Very-high-bit-rate DSL) technology offers a new alternative, improving performance by 50% - 90% by reducing the noise over a copper line, according to ABI Research.
"We are seeing accelerating interest in the deployment of VDSL2 Vectoring. Based on responses to a recently conducted global operator survey on VDSL2 Vectoring deployment strategies – 60 percent of those responding are currently deploying or in trial with VDSL2 Vectoring. Although they won’t be able to match Gigabit speeds offered by some operators, VDSL2 Vectoring will easily provide speeds of 75-100Mbps at significantly less cost than FTTH,” wrote Teresa Mastrangelo, principal analyst, Broadbandtrends.
Described as the next generation of DSL, VDSL offers significantly faster speeds using existing copper wiring. Whether you want to stream TV, movies or music, or communicate with friends across the globe, VDSL will enhance your online experience considerably. With no rewiring required, VDSL is ideal for delivering super high-speed broadband Internet connectivity to dwellings within large apartment complexes.
VDSL ready for launch in Australia
In Australia, rather than deliver fibre to every premises (FTTP) as the former government intended, the National Broadband Network Company (NBN Co) has commenced trials of Fibre-to-the-Node (FTTN) and Fibre-to-the-Basement (FTTB) network models.
A large-scale FTTB rollout now appears likely to launch following the recent success of a trial involving 150 metres of internal copper wiring in a Melbourne based apartment building, producing download speeds of 108Mbps and upload speeds of 48Mbps.
Under the FTTB plan, the fibre optic cable ceases at the basement or telecom room of a multi-dwelling unit (MDU), and is linked to the existing copper local area network using a DSLAM (Digital Subscriber Line Access Multiplexer) exchange developed by Alcatel-Lucent in accordance with an existing supply contract with the NBN Co.
The next step is to establish a link between Alcatel-Lucent's DSLAM and the VDSL modem router that sits inside each apartment. Achieving compatibility between the technologies is critical. The NetComm Wireless VDSL/ADSL WiFi Gigabit Modem Router (NF4V) therefore features an NBN compatible Broadcom chipset to support VDSL (Very-high-bit-rate DSL) services, the NF4V also interoperates with Alcatel-Lucent's exchanges (DSLAM) to deliver the bandwidth needed for video streaming and other bandwidth-intensive activities in apartments with multiple TVs, laptops, tablets and smartphones.
NetComm Wireless and VDSL
NetComm Wireless has developed one of Australia’s first NBN compatible VDSL modem routers. The NF4V is available to leading ISPs, and is designed to deliver blistering fast broadband access to single and multi-dwelling (fibre-to-the-basement) deployments.
The NF4V offers a range of connection options and networking features designed to suit all of your communications needs. Connection to the Internet is achieved via the VDSL/ADSL modem for connection to DSL today, Fibre to the Node NBN tomorrow or the Gigabit Ethernet WAN port for a possible fibre connection in the future. With carefully developed hardware and software features, this router ensures that it is optimised for use today and well into the future.
Create a powerful 300Mbps WiFi network to connect multiple wireless enabled devices throughout the home or office; and make up to 4 high speed wired connections using the Gigabit Ethernet LAN ports. Insert a USB hard drive into the USB ports to enable file sharing amongst connected users and slash your phone bills by using the FXS ports to make VoIP calls.
NetComm Wireless has also developed a remote splitter/filter, the VDSL2 Central Splitter (C10100NP), to enhance the signal. Once installed within the premises, the device separates the ADSL and VDSL signals and voice frequency signal to eliminate the need for inline filters.
With the right device, households and businesses in Australia and worldwide will benefit from drastically improved capacity, latency and noise.
