NEW DELHI: Surfing the Internet in trains without using data card seems to be a distinct possibility now as the Railways have got the much-awaited clearance from space agency ISRO for using the satellite for the purpose.The Indian Space Research Organisation (ISRO) has given the clearance for using the frequency from KU band for using the satellite for Internet, said a senior Railway Ministry official, adding it will be for the first time that Internet will be operational in moving trains through satellite.Though Railways had proposed two years back to provide Internet in trains, the project could not take off due to the absence of ISRO clearance."ISRO's clearance for using frequency from satellite for Internet is mandatory. Now that we have got the clearance, work on the project will commence soon," said the official.As per the proposal, three rakes of Howrah Rajdhani will be uplinked with satellite for facilitating Internet in coaches on a pilot basis.Since it is a pilot project the Internet service will not be charged from the passengers, said the official.Railways have sanctioned Rs 6.30 crore for providing Internet facility in Howrah Rajdhani. The work will be executed by a Mumbai-based company.Now custom-made antenna will be installed on the locomotives of the train and coaches will be linked through Wi-Fi connectivity, he said.According to the procedure to be followed, passenger will get a password in his mobile phone after dialling a number given by the TTE. The passenger can make the Internet operational with the use of the password.If the pilot project becomes successful then other trains will also be linked with satellite for Internet purpose.
