Last time I posted something about accessing Email on HF Radio. Well, things have now changed. No longer can you just access email on HF Radio but you can also access broadband internet via the HF Radio. You can surf the net, watch TV, do Video Conference and so much more. This is all thanks to the Brilliance of one Papua New Guinean, Wilfred Amai.
Wilfred who owns Skylink Technology is putting Papua New Guinea at the Top of the World. PNG has now an alternative to satellite dish. Gone are the days of satellite, gone are the days of cables. PNG will go wireless and be the FIRST in the World to access Broadband via HF Radio. It is just as similar as using Email on HF Radio, but the only difference is SPEED.It is a thousand times faster and you can download a 34Mbytes data less than 3 seconds and the speed is increasing. He is working on developing the speed to reach Giga bytes per second. It seems impossible at first but Wilfred as discovered an innovative NEW technology that has been PATENT in Australia. No-one can copy his work.So the war is brewing now, as we have just made a presentation to Telikom and already Digicel is calling for another presentation.More to come!!
SKYLINK Communication Limited is an IPA registered 100% Papua New Guinean owned company specializing in the research and development of innovative Communication Systems.
The main vision of the company is to develop and market a cheaper and more robust communication system that is user friendly and as an alternative to existing systems of telecommunication. The company derived its inspiration from the fact that PNG’s geographical and topographical setting rendered telecommunication in PNG very unreliable, ineffective and costly.
Rationale of behind the use of Ionosphere
The ionosphere is the upper most part of the atmosphere and is ionised by solar radiation. This gives ionosphere its property to refract radio waves such as short-wave. When using High Frequency bands, the ionosphere is utilized to reflect the transmitted radio beam. The beam returns to the earth’s surface, and then be reflected back into the ionosphere for a second bounce. The ionosphere in its sense acts as a satellite for Radio waves.
Ionosphere at 300km in the atmosphere will refract HF communication signals carrying large amount of data in real time improving on delay effects experienced by geo-stationary satellites at 36 000km.
The present invention relates generally to a data transmission system and in particular to a system for transmitting and receiving data at very high speed over a standard wireless HF communication link. Although HF radio frequency data transmission systems have been in existence for many years, no one has yet found a way to transmit large volumes of audio, video and data content in a real time, high speed environment. What that means is that this new invention can now enable people to send and access large volumes of data (through the internet) cheaply using the HF system everywhere, including rural areas.
This high speed communication system has also been developed to ensure the security of data communicated through the network, whilst redundancy has also been built into its systems so as to maintain uptime as much as possible.
Redundancy means having alternate routes for data traffic to be routed in the event of the default route malfunctioning. Redundancy also means having backup power in the likely event that main power goes off. It means building ‘intelligence’ into the network to enable it to automatically adapt to failing data traffic routes without human intervention i.e. the use of routers with automatically updated routing tables constantly determining the next best route.
In terms of compatibility, this communication system is compatible with all standard internationally approved equipment. This allows all types of computers and peripherals to be connected to the network. In fact, the system has been initially trialled in the presence of PANGTEL in January of this year, 2007, to ensure that it complied with regulatory standards of the use of the HF channel and that it didn’t interfere with other commercial users of the Radio Frequency Spectrum in any illegal way.
The trial involved downloading a 22 megabyte file in approximately 20 seconds using a narrow channel standard HF frequency at around 4.920 MHz. This translates into a speed of approximately 9 or 10 Mbps. This is more than 3,000 times faster than a commercial HF data transmission system. That is because commercial HF Data communication systems are only known to be able to work at speeds of up to around 24 kbps at the most. Apart from government and corporate dignitaries, there were also technical specialists from PANGTEL and other HF communications companies present at the trials to verify the system.
