Fiber to the basement + G.fast is the obvious choice today to upgrade apartment buildings. Telecom Austria A1 did some of the first testing of G.fast in the field, an early proof of concept. In 2014, they reached 536 megabits with equipment from Alcatel and Sckipio. See Live G.fast at Telekom Austria. The A1 press release speaks only of "hundreds of megabits"; I expect most customers will see 500-800 megabits.
A dozen telcos have deployed 10's of thousands of G.fast lines. It works. Curtis Frankenfeld of Centurylink reports, "No disappointments on performance. The results in the field on real cable approach the lab results." Adtran alone has 65 customers in trials. I expect most of them will soon be announcing deployments to MDUs.
The eventual cost of G.fast should be little more than VDSL, based on the fill of materials. It's early days and competition is weak. I hear rumors of higher prices, which may be discouraging some.
nbn in Australia is running fiber to the basement and to distribution points but for now using VDSL rather than G.fast. These problems should resolve; Australia should use the clout of their large network to get the prices down.
Telecom Austria initially expected deployment in 2016, but seem to be falling a little behind. Most of these lines will be built by August of 2017. The 2014 Alcatel press release pointed to a possibility of 400,000 apartments in Vienna alone, but I've haven't seen that announced.
Here's the sckpr.
A1 expanding broadband Internet in downtown Graz with new design option
Category: Network expansion
• Configuration variant FTTB (fiber to the building): data transfer rates of several hundred Mbit / s for apartments in existing buildings
• New fiber optic lines to the basement
consist • Existing wiring in homes remain without chiselling in stairwells and apartments required
• expansion plan for the next 12 months includes more than 30,000 households in the districts Geidorf, St. Leonhard and GriesWith the expansion variant FTTB (Fiber-to-the-building) for the supply of ultra-broadband Internet aims A1 especially on the densely built-up urban area where mainly multistorey, existing buildings are located.
In expanding brings A1 high-performance fiber-optic lines to a converter in the basement, which forms the transition to the existing wiring. If necessary, a complete rewiring with fiber to the home can be made at a later, favorable to the owner at the time.
New technologies enable several hundred Mbit / s on copper lines
with the FTTB variant we can, thanks to new technical processes like G.fast on the remaining copper lines in house data rates of several hundred Mbit / 's per apartment. Even large buildings are best suited for this method, "said Marcus Cruel, A1 CTO.
Configuration variant FTTB Releases Ultra-High in the inner cities
in the urban areas are many buildings with monumental staircases that construction of new cable channels and the restoration to its original state would make sense only as part of a general renovation. The FTTB strategy the owners decide as needed over a full wiring. "The downtown Graz wins by this expansion significantly more attractive for families with high media consumption and for the trade," said Siegfried Nagl, Mayor of Graz.
Extension for more than 50,000 households within 12 months
A1 plans to provide them with the FTTB variant in the first phase of expansion within the next 12 months, more than 30,000 households in the districts Geidorf, St. Leonhard and Gries. This method of broadband expansion is an important component to achieve the recommendations of the Federal Government and the European Commission, which provides to supply at least half of all households by 2020 with data rates of 100 Mbit / s.
A further 20,000 households in less densely built-up areas ( Wetzelsdorf, Webling, Andritz and Maria Trost (fiber-to-the-curb) supplied in the coming assembly using FTTC variant that is better suited to less densely built-up areas. New buildings are supplied from A1 usually with fiber to the home ( FTTH, Fiber to the home).
