Disadvantages of VDSL2
Although the transfer rate for the user is growing, it does not do without pitfalls, which providers, of course, do not report.
I will tell a little about the new program of Deutsche Telekom built on VDSL2 technology . And of course about the shortcomings.
The advertising campaign in Germany went under the brand name "T-Home Speed".
They declare speeds up to 10 / 50Mbps Up / Down, now mostly up to 25MBits.
The actual speed on these DSLAMs in the area before 19/58, he tested himself. Of course, in too ideal conditions, when to a point less than a meter.
That is, everything seems to be fine, and they offer it with a margin, but of course they “forget” to tell customers that with increasing distance to the access point, the characteristics of the receive channel become worse, even than with the simple ADSL2. Therefore, many of these 50mbit will not get it. If the distance from the house to the telecom point is more than a kilometer and a half, there is no point in making this connection for yourself.
And also, did you know that only 24 clients will be connected to one DSLAM, and then there is a gigabit fiber ... so if everyone starts downloading the maximum, then the speed will automatically decrease to 1000/24 = 40 Mbps (not taking into account the costs of encapsulation!)
T-Home Speed is currently available only in 12 cities in Germany, where several thousand access points (DSLAMs) are already installed. But the prices are exorbitant: 70? and 85?, depending on the package of services.
It is worth adding that now 16MBit packages are in the region of 25-30?
')
It is interesting to compare with South Korea, where access is considered normal at about 100 Mbit and is 2-3 times lower than the stated telecoms.
Telecom is currently losing tens and hundreds of thousands of customers every month (!), And they hope to return some of this program.
