Today, for broadband access technology everybody talking which is the better technologies for wireless.. LTE, TD-LTE, FD-LTE, LTE-Advance, but soon it will be SHIFT to wireline, because nonetheless, the speed and bandwidth battle is always won by the Cable Broadbad.
There are two different medium for wireline access fiber or copper. For greenfield deployment fiber technology such as PON is the best solution. But... big telco provider tend to use existing twisted copper investment while gradually deploy their fiber network, how much copper technology can deliver the speed? following graphic is the answer.
With VDSL2 as the base line, bonding is like bundling two pair of cable to get more bandwidth. headphone.While DSL Phantom Mode technology is a bit of magic for the copper network. It
creates a third (phantom or virtual) channel over 2 regular copper
pairs. Vectoring is canceling crosstalk between two pair of copper, the idea is same like noise-canceling technology in your headphone.
And the state of the-art-technology is ITU-T pre-standard, G.Fast. The main requirement of this standard is to achieve high peak rate 500 Mb/s at 100 m. By combining VDSL+, bonding, phantom-mode, vectoring and G.Fast its field-proven we can achieve more than 1 Gb/s at 70 m.
