Bibern Google EarthThose gigabits just ain't delivering. The glass is half full: many customers are getting downloads of 200-400 megabits. That's pretty darn good. The glass is half empty: the gigabits promised are not being achieved.

Carsten Roetz of Swisscom writes "The test customers in the village of Bibern get between 285 and 402 Mbps downstream and between 85 and 109 Mbps upstream. Results depend on copper cable length: on short copper cables (ca 24 meters) we were even able to reach 624 Mbps Downstream / 151 Mbps Upstream in field but without connected customers."

Most of the ~150 homes in the Swiss town of Bibern are within 200 meters of the city center, ideal G.fast territory. Whether 200 megabits or 500 megabits, G.fast actually getting to customers is a milestone.

Swisscom leads the way in network expansion: first customer test for the new G.fast technology

Berne, 04 May 2015

New web applications and the increasing level of networking call for ever higher bandwidths, and Swisscom is continually expanding its broadband network to respond to this. Swisscom is now testing the new G.fast data transmission standard under real conditions for the first time and connecting the first test customers. The G.fast technology and a combination of fibre-optic and copper lines permit bandwidths of up to 500 Mbps. Swisscom is the first telecommunications company in Europe to allow customers to surf the web with the standardised G.fast chipset.

Wide-ranging streaming packages, HD quality videos and new cloud services are just a few of the reasons why both residential customers and companies need more and more data at ever higher speeds. Even today, the volume of fixed network data traffic already doubles every 16 months. With this in mind, Swisscom has been driving the expansion of ultra-fast broadband technologies for years. Over 1.4 million households and businesses benefit from bandwidths of at least 50 Mbps. In the future, the new G.fast transmission technology will allow customers with an FTTS or FTTB connection to surf at speeds of up to 500 Mbps. This is achieved by using a higher frequency spectrum on copper cables. In the case of FTTS, fibre-optic cables are laid up to a distance of around 200 metres from the building. Larger properties benefit from an FTTB connection, with fibre-optic cables laid right up to the building itself.

First field test and customers with active services on G.fast

Swisscom carried out a field test of the G.fast technology in April, enabling it to gather initial experiences under real conditions. As a result, the village of Bibern in the municipality of Buchegg, canton of Solothurn, is now one of the first places in Switzerland to benefit from the new transmission standard, and since the end of April 2015 the first customers have been able to surf at speeds of up to 500 Mbps even if they do not have an FTTH connection.

Swisscom is planning to expand G.fast for all FTTS and FTTB connections from 2016. Until then, G.fast will be optimised for the Swisscom network in cooperation with the company’s technology partner Huawei.

High investment in broadband provision throughout Switzerland

Swisscom wants to connect more than 2.3 million homes and businesses to the ultra-fast broadband network by the end of the year, investing more than CHF 1.75 billion in the expansion of the IT and network infrastructure in 2015 alone. To supply locations outside the major conurbations, Swisscom relies on a mix of technologies that permit ultra-fast bandwidths: vectoring, Fibre to the Street (FTTS), Fibre to the Building (FTTB) and Fibre to the Home (FTTH). FTTS and FTTB currently permit bandwidths of up to 100 Mbps. Swisscom is thus making a key contribution to the ongoing digitisation of Switzerland and maintaining its position as global leader: according to Akamai, Switzerland is ranked first in Europe and third globally for high bandwidth coverage (>10Mbps).

G.fast News
A remarkable 400 people attended the very strong Broadband Forum BASE events in Berlin and Las Vegas. Trevor confirmed BT would pass the million this year. Cioffi projected “Waveguide DSL” could carry 10 gigabits a kilometer as well as a terabit 100 meters. Werner sees a 4X improvement in upstream with cDTA. Much more in next issue.

Deutsche Wants a Gigabit, Finally Realizes 50 Meg Isn't Enough http://bit.ly/2zeZ5oZ
Deutsche Telekom is finally realizing that 50 megabit DSL won't make it against gigabit cable. VP Franz Seiser is blunt. "We must change radically, become disruptive and, above all, throw away things," he proclaims at BBWF. After years of DT insisting 50 megabits is plenty, we now hear "it is about Gigabit products" from DT's Robert Soukup.  
    A lucky building in Frankfurt will receive 500+ megabit service as ultra-conservative Deutsche Telekom experiments with G.fast. Soukup told BBWF, "We're going to have a field test in Frankfurt with G.fast and Fiber To The Building (FTTB.) We will know by the end of the year if this is the right way to go." Hint to Soukup: Yes it is. G.fast is working well at a dozen telcos I;ve talked to.
     The details are surprising. DT is going for CORD, Open Source, Calix, and Radisys. http://bit.ly/2zeZ5oZ

1.6 Gig in Sckipio-Calix Test http://bit.ly/Calix16
A telco tells me they are getting impressive early results from the Calix 48 port DSLAM with the new Sckipio 212 MHz chips. There still is work to do but this is encouraging. 
    Carriers want DSLAMs with more than 16 ports to reduce the deployment costs from the basement or larger field cabinets. Speed matters to the marketing side of the company; AT&T's CEO believes he must offer a true gigabit to match cable. (They've been getting ~750 megabits with first generation chips. http://bit.ly/Calix16

Reverse Power 4 Port DSLAM for Australia http://bit.ly/NetcommRP
Australia is connecting 1M homes to G.fast, some with a Netcomm distribution point mini-DSLAM. It's a small unit designed for pole or pit mounting. It's waterproof, pressure proof, and temperature resistant. Their matching home modem is bittorrent friendly, with two USB ports for a hard drive dedicated to sharing.
     A reverse power unit at the customer, the NDD-0100-01, can save the cost of bringing power to the DSLAM. They don't expect many orders until the second half of 2018, as nbn is waiting for the second generation chips. Netcomm demonstrated RP with BT Openreach in August. http://bit.ly/NetcommRP

Australia Makes it Official: G.fast to Million Plus http://bit.ly/GFAussie
No news here. In September, 2015, I reported Australia's nbn Going G.fast. This June. I reported the million home fiber to the curb (kerb?) was beginning. Unfortunately, they are no closer to figuring out where to find the needed $10B to $20B to cover the cost overruns. Instead, the parties are battling in Parliament about who is to blame. http://bit.ly/GFAussie

2 Bonded 212 Lines = 3 Gigabitshttp://bit.ly/twobonded
Sckipio at BBWF is demonstrating 3 gigabits down, nearly a gigabit up, over two phone lines, bonded. Twice the bandwidth (212 MHz instead of 106 MHz) times two lines is fast. Sckipio does great demos; at CES, they showed G.fast first generation chips delivering almost 1 gig upstream.
    “Sckipio is pushing Gfast to astonishing speeds with production silicon,” CEO David Baum proclaims. Calix is using the SCK23000 chipset in their 48 port gig+ DSLAM at the show. http://bit.ly/twobonded
