There is no doubt that one of the main advantages of WiMax is that allows to cover extensive geographic areas wirelessly, since counts on an operational range of approximately 50 kilometers. Very many more than the connectivity than she unfolds WiFi, and sufficient to illuminate great cities. But as the investigators and scientists always try to go a step beyond, a new device has already arisen that will allow to take the new technology more far. They are the Estratélites, a perfect alternative for the development of networks of broadband on national scale, since it allows a cover of up to 1000 kilometers of diameter.

One is globes, or rather airships that stay geostationary in a point determined at level of the stratosphere, that is to say, between 17 and 50 kilometers of altitude, but within the atmosphere. This, unlike the conventional satellites that are located in the deep space.

The comparison is not trivial, since as the broadband by telephone route has certain limitations, mainly by the limited ranks of speed that allow, many have thought that the ideal alternative is to provide with connection via satellite. But at the moment its operation is too expensive like destining them to provide this service, and they are not either able to offer connectivity more than to a limited number of users.

In contrast to the satellite, the ship airship reduces the response time, although it covers a smaller area with earth. That yes, is the very many option economic than the putting into orbit of a satellite, since this one hill between 25 and 30 million dollars.

The connection via air balloons would be an intermediate solution. And it is that it does not have the limitations of capacity of the telephony, and in addition is cheaper than the connection via satellite.

By its height, in addition, they are ideal for the location of points of illumination of WiMax networks, that require high places. And although these ships can use all type of technology to offer connectivity, the experts speculate that the winner will be definitively the new wireless standard.

Flying whale

The Estratélite, of about seventy and five meters in length, has whale aspect, is covered of solar paddles in its superior part who feed their electrical motors, and only must descend periodically to make maintenance tasks.

And it is that each Estratélite is designed to remain in a location until by 12 months. So that the original ship can is brought of return to the Earth to make the maintenance process and the technological improvements in the communication, without interrupting the service, a duplicated Estratélite will be used.

A single unit can provide Internet of high speed, signals of movable telephone and digital television and radio for an extensive area. Compared with the towers of ground communication lineses, it covers a greater area with response times that depend more on the internal communications equipment that of the distance.

Their those in favor maintain that this new platform of communications can eliminate the necessity of terrestrial towers of emission, since a single unit replaces many. This also implies that an area without this infrastructure, as it is the case of the countries less developed or nations faced in warlike conflicts, can install a network of broadband with relative facility. And at great speed. The ship can provide with connections of up to 120 Mbsp.

The Estratélite word is a registered tradename by Sanswire Network, branch of GlobeTel Communications Corp, although that does not imply that other companies have not arisen developer from similar technologies.

But like so, this system was presented/displayed to the public for the first time the April of the last year, and already there are projects to introduce it in Europe, the Middle East and Africa.

“We try to replace the satellites to smaller cost”, said to Leigh Coleman, president of the matrix of Sanswire, GlobeTel Communications, in that opportunity. And it added: “We think that this will change the form in which we are accustomed to communicate to us”.

Similar projects have been taken I finish by Aviation Technologies Group (ATG) in Bedford, England and by Inc. SkyTower, in Monrovia, the United States.

And the Latins definitively we will not remain back. Representatives of Sanswire already have met with the president of Colombia, that jeopardized its aid to impel the development of that technology in this country.

And there are reasons to be alert to the arrival of these ships. The last tests made in the University of York, in the United Kingdom, have been everything a success. Thus, the experts think that in a term of three to five years air balloons they could take care of the demands of connection of great speed without cables, at a highest speed.

The Chilean bet

But the Chileans we will not be mere spectators in the development of this new form to offer connectivity to extensive geographic areas. A similar ship is being developed at the moment in our country, although sure on smaller scale than the original project.

One is the Haps project (High Altitude Platform Stations), that leads the Metropolitan Technological University (UTEM), in collaboration with equipment of the University of Chile, University of the Border and Reunites. Thanks to a globe, all the zone between Santiago and Puerto Montt could be connected to Internet of high speed.

These ships can hold the position thanks to motors and they rise until about 20 or 25 kilometers, the lowest part of the stratosphere.

What their creators look for, is to generate a system of easy unfolding and low cost, to solve the communicational problems of zones until now neglected, generating a network of broadband IP of the type radio.

In addition, they say that it will be very useful in case of emergencies, since if there are faults in the communication by natural disasters or technical problems, a light truck takes the globe to the affected place and this one rises in just a short time.

What is a Estratélite?

The Estratélite, term coined by the North American company Sanswire, is a ship specialized of trip to high altitude, conceptually similar to a satellite, but that will be located in a geostationary position of the stratosphere between the 19 and 22 kilometers of altitude above sea level. The idea is that it is controlled remotely from tracking stations in the Earth and can provide a platform of communications of double via, offering to the services of wireless telecommunications of, cellular, movable broadband 3G/4G, MMDS, paging, fixed wireless telephony, HDTV, in time real monitoreo, among others.
