Internet.org launched back in last August by Facebook along with six leading technological companies, with mission of provising internet for every single person in this world. Today Mark Zuckerberg shared a report of progress on internet.org and technologies they are going to use to provide internet for everyone.
First of all Zuckerberg hardly believed that knowledge economy can resolve many of the problems faced by world today. Expanding internet access to everyone can make millions of job opportunities, people will get chance to use advanced services and thereby the knowledge economy will improve. Today only one third of world population get chance to access internet. That why he put forward this project.
In the first part of the project Zuckerberg and team join with telecom operators in Philippines, to offer internet access at low rates. He reported that after few months the number of subscribers increased by 25%, in Paraguay it is 50%.
Different technologies for different communities
As by Facebook survey reports 80 to 90% of world population lives in urban area where the 2G and 3G networks are available. Rest of the communities are lives in remote areas, where implementation of network infrastructure becomes very hard. Also different population densities are found in different communities. So same technology for providing net access to everyone becomes a bad idea.
For a dense urban area high strength signals can be transmitted by towers. In case of medium and low density areas signals must be transmitted from orbits, get coverage over wide area but strength of signals becomes very low. By making deep study on all these cases Facebook plans to connecting the world by using different technologies.
Facebook previously acquired UK based Ascenta drones company. Drones can covers a city sized area from higher attitude to beam internet signals. Drones can also fly close to the ground to provide more strengthful signals at possible conditions. Ideally drones operating at attitude of 65000 feet, lowest unregulated airspace.
At that attitudes drones are becomes very easy to control, wind speed are very low and have stable weather. These drones from Facebook rely on solar energy can remains in that attitude for several months. It also demands low cost for the production of such drones.
Drones never becomes applicable for remote places. Facebook’s connectivity lab plans for launching two different types of satellites for such places, low Earth orbit and geosynchronous Earth orbit.
Low Earth orbits are smaller and cheaper at cost, they located in lower orbits. In that way LEO can provide usable signal strength, mainly for accessing services such as web or voice calls. Signals from LEOs only available for a smaller portion of area, also demand for to fit antenna at ground stations.
The geosynchronous Earth orbit satellites orbits at height of 35786 kilometers above sea level. In that way such satellite can point out one particular area on land. It becomes helpful to make the configuration, cheaper at cost. Signals from GEO also becomes little weaker as it comes from great height.
Free Space Optics
To improving signal strength from drones and satellites Facebook connectivity lab tested for FSO system, a way of using light to transmit the data through space. It requires only lesser power and have extremely high bandwidth, can provide high signal strength.
Using this technology signals being send from Earth to orbit and laser equipped receiver can catch up data from the ground station. Facebook can provide stronger internet access through drones or satellites using FSO technology. At the same time FSO demand for line of sight from transmitter to receiver on ground station.
At the current stage Mark Zuckerberg and team trying to connecting people to their own service. They have both dominating mobile messaging and social networking platforms. In coming years they used revenue from their services for connecting entire world to internet.
