Dutch municipalities should not only think in terms of FTTH - TNO

Many local election plans are unnecessarily ambitious with broadband, Dutch research institute TNO said. With the municipal elections, many political parties and municipal governments are saying they would like to have FTTH in their area. TNO noted a number of alternatives, such as upgrading to copper and possibly also wireless connections.

TNO senior research scientist for ICT-Network Planning said the emphasis placed on fibre “exagerated”. He noted that people want bandwidth but said there were a number of different technical alternatives and ways to use the available money for investments. One good example stated is G.Fast, which releases much more bandwidth over short distances, over existing copper lines.

These kind of network expansions would accelerate access to better speeds and give more capacity, while further migration to FTTH could happen at a realistic pace, if demand for bandwidth still rises. "The total costs would then not have to be higher than for switching to FTTH in one go."

TNO in European G.Fast project

TNO contributed to a European project in 2015 and 2016: 4GBB GOLD/G.Fast. The tagline was "Gigabits over the Legacy Drop". A number of vendors and operators collaborated with universities and therefore also TNO to further develop the G.Fast standard of 2014.

G.Fast has matured into a mature standard of the Broadband World Forum, and can be combined with Fibre to the Distribution Point (FTTDp). A fixed network manager –KPN in the Netherlands- could bridge the last 200-500 meters with traditionally paired copper and new connection technology, such as supervectoring or G.Fast.

This mixed scenario will over the coming years release sufficient capacity. Phillipson noted the fact that in Amsterdam, houses have on average only a very short piece of copper from the last distributor. For outer areas, other possibilities, such as fibre, could be combined with wireless technology.

KPN introduces Vplus

KPN moved away from FTTH a few years ago. It now only deploys fibre for new construction buildings. With existing buildings, KPN is working to upgrade its copper network. After vectoring on VDSL2, the next step is to use Vplus with a 35b profile. By doubling the spectrum, the bandwidth can also be doubled, pretty much. Using these methods, KPN can provide 200 Mbps as advertised maximum speeds. If a customer opts for the more expensive pair bonding, 400 Mbps is also possible
