So, the digital gap between urban and rural decline.
Telecom professor wants every cottage in Sweden to be able to get 100 Mbit / s. His solution is super base stations to reach 20 mil set in the television masts.
As of cultivation, a professor of telecommunications at the University of Lund, want to reduce the digital gap in Sweden, and eventually the world.
– Two percent of Swedes and more than half the country’s land area has no access to mobile broadband, he said.
– Sure seen it sticks on the mobile screen over a large area. But that does not mean you get a canal or even can pay by mobile. We need more capacity in rural areas to take advantage of tomorrow’s connected society, mean per culture.
He warns that the digital divide will increase as more and more emphasis is placed on big cities.
Along with Jaap van de Beek, Professor of signal Processing at Luleå University and representatives of nature-oriented industries through the LRF, the tourist industry’s central organ Visita and Akademi Norr lobbying per culture to create a new national mobile broadband network.
– Our aim is that there should be 100 Mbit / s in the cottages in the countryside for ten years and that people and businesses will be able to use mobile payment everywhere. And we have a solution for how it could be done, he said.
The operator Net1, sometimes called rural operator, is not enough, says Per farming.
– It’s great that the is there, but people want a single sim card, which can be used to both rural and urban areas. For rural areas, it will be too expensive with multiple parallel networks, and of course will Net1′s network to be part of the future Common. Maybe even the basis for it, he suggests.
In the big cities of screaming customers more capacity and better indoor coverage. There is a shortage of spectrum unused. In rural areas, however, there are plenty of spectrum, and the challenges are long distance and capacity.
professors’ solution for rural areas is a combination of super cells with advanced antennas and extremely power efficient macro cells, which can do without electricity and fiber.
Super base stations to reach 20 mil in the 20′s of the country’s major television masts would provide national coverage. Along with advanced antennas, MIMO massive, they would be able to provide much capacity at relatively low cost over long distances. The cabins need to install a terminal with advanced antenna connected to the power outlet.
Technology solution with super cells are “almost” ready. Ericsson supplied base stations with 20 mile range and speed of 1 Mbit / s to Australia in 2006. They advanced antennas needed for higher capacity developed 5g and is expected to begin within a year.
100 Mbit / s to the cottages does not mean that you can call with his mobile, the distance between the mobile and super bass is too long. But professors have an idea:
What is required is the traditional base stations, macrocells, who can do without access to fiber and power.
There is of course a challenge. But macro bases could be extremely power efficient and equipped with solar cells. Instead of fiber and microwave links, the researchers suggest that the traffic sent through the parts of the spectrum that are not used in the sparsely populated parts. A solution to reduce energy use by researchers advocate called “ultra-lean design” and was developed by Ericsson 5g.
So far, the interest from companies and financiers has been low.
– their focus is the profitability, and there are many more who are willing to pay for mobile broadband in the cities. We work to reduce the digital divide, not to make money, says Per farming.
He hopes to eventually get support from the business community, because many Swedish companies have their operations in rural areas. In the connected industrial future is mobile broadband increasingly important in order to create added value.
– A large part of Sweden’s GDP is generated by industries in rural areas. As the forest, mines and water power. In the connected future will be mobile broadband increasingly important in order to create added value and there must be a mobile broadband network for the entire country, says Per farming.
Five quick questions for per culture:
who will be the new network?
– Someone not driven by maximizing profits. It might be a foundation, like Banverket or anyone with an interest in society and who also want to create an added value to the industry by linking the machines in rural areas.
You searched money from Vinnova, but got rejection. What was their motivation?
– To solve these problems, the mobile industry itself with 5g. But that is not true. The countryside is not included in the specifications of 5g. All of us who are engaged in this work on a voluntary basis so far. We want to make a change for real, but it is clear that it takes time. We expect ten years.
Telia’s network manager claims that one of the subtleties of 5g is that it will provide 100 Mbit / s everywhere in the countryside?
– sure, there will surely be some 5g masts out there, but no more investment than what motivates subscriptions out there. It would be naive to believe that it will be better than today.
There are other technical solutions to bring mobile broadband in rural areas, for example, Facebook’s Project Loon with hydrogen balloons. How do you see it?
– It’s a fun experiment, but you have to build on something that is basically existent and has a low operating cost.
What costs do you expect?
– It depends on the scale, and are difficult to estimate. And we are simply not there yet. We see the network in Sweden as a prototypyta where this technology will then be spread and used to include the two-thirds of the world population currently not online. Does this work it could be used in all places in the world that do not have access to mobile broadband
