A dream of connecting to the internet when travelling througth sky is going to come true and. In the race of modern world disconnecting from the internet feels as bad running slow in the race, internet is the essential part of human life now a days.So when we disconnected then a part of our life got discontineous.So the problem is quite difficult to solve as there is many frequencies are handled while flying but On 3 June, a demo airplane brought by Honeywell to India and demoed a solution to just this problem.It is connected connected to internet through setalite wifi across the globe.This flight may remove the gape between internet and passenger while flying. High speed wifi connection in indian flights in near future.
In partnership with Inmarsat and Iridium, Honeywell demoed a mechanism for Providing a high-speed Wi-Fi to any aircraft flying through the skies at high speed. For the purposes of the demo, Honeywell mounted an antenna inside a radome mounted on a test aircraft. The antenna can receive data at a rate of up to 50 Mbps from any of the four Inmarsat satellites in operation around the world. This solution is called GX Aviation.
The test aircraft itself is a modified Boeing 757 aircraft, and it’s rather special in its own right. For a start, the aircraft has an extra pylon mounted on the left of the fuselage, this is for testing engines. The inside is packed to the brim with all sorts of electronics and is devoid of creature comforts, save for about a dozen or so seats clad in weathered leather. Other than the bare essential insulation, everything else inside the aircraft is exposed. Even the air conditioning in most of the aircraft is provided by brass tubes.
Better yet,The aircraft also loaded with a LCD monitor in the cockpit for watching the pilot’s activity and also we also got to listen on ATC(air traffic controler) communication via headphones that were very convenient.It was a very joyfull experience, to say the least. Yours truly, listening in on ATC conversations. What aircraft can offer this luxury?
The rest of the space in the aircraft is filled with metal cabinets that can house various items of equipment like servers and modems.
For Honeywell’s demo, this process was quite simple, no different from connecting to a router at home. Honeywell’s Sasi Kancharla, Customer Business Leader for Middle East and India, explained that the receiving antenna sent the data to a box near the rear of the aircraft. From this box, the data is routed to what appears to be a router of the type you’d buy off the street.
Browsing the interwebs at 24,000 feet was indeed fun, and it was fast, but there is a number of dropouts in-flight it is because of the way the satellite-transmitted internet works and is an inevitable part of the experience.
The signal is transmitted down via one of four Inmarsat Global Xpress satellites placed in geostationary orbit above the Earth. The mounted antenna moves to track the satellite. The satellites themselves operate in the Ka-band (20-30 GHz) in “spots”. Each spot is strictly defined by the bandwidth and spectrum available, reducing interference.
The speed is also very fast, it is reported that the download speed 30Mbps and upload speed is 2Mbps at a ping around 580ms and the satellite almost 36,000 km above from the surface of the earth.And also note that the redius of our earth is 6371km only.Geostationary satellites orbit at an incredible distance.
The entire setup, according to Kancharla, is cheaper and 10-100 times faster than other offerings in the market. Honeywell Aerospace is working with various airlines in India as well as the government to make in-flight Wi-Fi a reality.
Bear in mind that we experienced these speeds on a test aircraft with a handful of people on board. The real-world situation will be very different.
Together with this in-flight Wi-Fi offering, Honeywell Aerospace is offering “Connected Aircraft” solutions designed to improve the operational efficiency of aircraft and ground crew. This also includes all-weather radar for generating accurate, real-time weather maps for the pilots.
I don’t think I’m alone in planning my content consumption well ahead of any flight. Hard disk? Laptop? Fully loaded phone? Headphones? Check, check, check and check. No flight is possible without these.
Now the import thing is that the security, if the wifi is provided then it may have vulnaribility and the hacker can hack the wifi and gether information or even can exploit the aircraft interface if it anyhow connected to the aircraft controlling device.So security is the most import part while implimenting such facility and make a sucure and joyfull travelling across the gbobe. Hope in near future we indian also can get privillage of accessing internet in far way from ground with proper security.
