Yes it is the one using the VDSL vectoring technology but I not sure about the packages. The download speed will be probably around 15-20Mbps and upload will be probably around 1-2Mbps.

even with VDSL2 vectoring, it is still impossible for tm to offer the same speed as unifi using fiber. Since the signal travel in copper line will attenuate and deteriorates quickly with increasing distance. in other words, the longer the distance user with dslam/exchange, the lower the speed user will get.

Starting from 1.6 km (1 mi) VDSL2 performance is equal to ADSL2+.

after all, fiber is still the future.

TM will use Fibre To The Cabinet(FTTC). The possible setup would like in the picture below.Only the last mile to customer premise will use copper.

The maximum available bit rate is achieved at a range of about 300 meters; performance degrades as the loop attenuation increases.

even with streamyx 4 and 8mbps, many user still can't subscribe due to "too far" - excuse/reason given by tm staff.

Just log into current adsl/router and find out downstream attenuation value and input it at the website to find out approximate distance.

Impossible.....
Attenuation, not SNR bor.......
