May I know whether Streamyx version of VDSL will come with triple play service like what Unifi have? Internet+Phone+IPTV with dedicated bandwidth. Not sharing the same resources like current Streamyx 4/8mbps now.

Yes. VLAN will be implemented. VDSL has been used in old type Condos and apartments for years and so far it runs on VLAN too. So HyppTV, Phone and Internet should be seperated if it is on VDSL2 Vectoring.

For me, I still think that the Japanese approach is still the best. When you want internet connection to your home in Jpan, basically you have to pay for 2 thing...first is the cable company...second is the ISP. The cable company is the one who have invest in laying the cable either cooper or fibre around japan while the ISP company provide the internet connection. Bcause of this, their fibre cable coverage is so wide compare to us. Since in Msia, the ISP is the one who do the cable installation and at the same time providing the connection, the process tend to be slow. Entering 2017 and mojority of TM subscriber is still using streamyx. sweat.gif

The rate there is also damn cheap. For fibre cable rent, you need to pay about 4600yen about rm170. Then after you have cable, you pay about 460yen (about RM17) to the ISP. So total about RM187 per month. That price is for 1Gbps speed. I also shock when Im hearing that from my friend who study and work there. To compare that price to a real life situation, average part-timer there make RM46 per hour while here in Msia, part-timer usually make 5 ringgit per hour. So, to pay RM187, our part timer have to work for almost 37 hour while in Jpan, they only have to work for 4 hours to pay their internet bill. cool2.gif

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.

.....hate to break it to you, but with VDSL standard....you probably get 34268kbps. (Divide VDSL2 by two)
So....no 50Mbps for you....

EDIT: Reason being most high-rise uses VDSL instead of VDSL2.

If VDSL2 Vectoring is being used, multiply* VDSL2 bandwidth by 3.

At least can get upgrade for my Streamyx if my area really under their project. No UniFi coverage currently so yea, when 30Mbps is not even available, 50Mbps is totally just a dream.

If I can get 20Mbps downstream and 5Mbps downstream I'll be glad so much. What to do, since I'm living in rural areas. Not feasible for TM to lay their 'precious' fiber cable here. Currently I'm using streamyx 8mbps with JUST 512Kbps upstream speed. Gosh! iCloud backup take up so much time to do and I need to use my mobile data in order to do it fast.

Honestly, I don't really care about download speed anymore...Over the years, I've gotten so used to it, I don't even get mad anymore when I have to leave downloads overnight to complete...At this point, I'll take whatever I can get, even just double the speed to 8Mbps...A price cut would be nice too... But then again, seeing how TM likes to screw us Streamyx users upside down, it does seem unlikely...

The one thing that DOES annoy the hell out of me is the f***ing upload speed...In this day and age, an upload speed of 500Kbps is a cruel joke...At least give us 5Mbps upload speed this year, goddamnit TM... ranting.gif
