Ericsson for the first time in the world have achieved the speed of 0.5 Gbit/s using technology based on VDSL2
The company Ericsson for the first time in the world has demonstrated a real-time technology based on VDSL2, which has achieved data transfer rates exceeding 0.5 Gbps.
Thus, operators have an opportunity to provide broadband services such as IPTV. Using this technology, operators can expand the system of optical access through the copper lines on the «last mile», and as a consequence of achieving maximum use of existing infrastructure. This means that more subscribers will be able to enjoy broadband services such as HDTV and video on demand, at home.
New technology also allows the use of existing networks based on copper cable as a solution, which transport traffic base stations. This brings the moment to begin the deployment of high-speed mobile services based on HSPA and LTE.
Compensation for cross-navodok, also known as «vectorize» VDSL2, provides high speed through transmission, increasing the VDSL2 performance by reducing interference from other copper pairs in a bundle of cables. The result is increased throughput, increased range of communication and as a consequence of the growing number of subscribers, which can be connected to the network. The technology also provides for tracing cable channel separation (in terms of interference), thereby significantly increasing the efficiency of power management, which can reduce power consumption.
Binding of channels is to combine several channels into one and implies that the node has several copper lines. During the demonstration was achieved aggregate speed in excess of 0.5 Gb / s on the line length of 500 meters, combining 6 channels. Standards for VDSL2 and linking channels already exist, and work on standardization of vectorization has come, and are expected to be completed by the end of 2009.
