"Technically it is possible.
"Each mobile operator will have its own guidelines for the duration of escort europeu 2000 metadata storage and would not normally be made public for obvious national security and law enforcement escort trany reasons.".
The plane may have been flying too high or too fast to register with cell towers, according to telecoms experts, but careful analysis of the passengers' cell phone records will need to be completed to be certain.It is being done as part of the investigation.".Passengers on high-speed trains in Japan and other countries can make calls via 3G networks at speeds of up to 240 kilometers per hour, but cell towers aren't able to register a signal beyond those speeds, Rojas said.In his complaint to the police, the man said he received an e-mail from an unknown person offering to sell him bicycles, called the provided phone number and talked to a man who introduced himself as a company manager and offered him to make.The telecom expert said that he'd place particular focus on the phone numbers of passengers from Thailand or Malaysia.Unlike in urban areas, where cell phone antennae are typically pointed down toward the ground, backpage st louis escorts cell towers in rural areas are up to 30-45 meters high and are often pointed at an angle meant to cover wider distances.Was the plane too high?So if you're up in the sky, you can receive the signal as well, Rojas said."But anyway, we are still checking.Several other calls were made using airphones.If metadata was detected from cell phones on Flight 370, surely it would shed more light on the missing plane's flight path?

Would be problematic according to Bill Rojas, director of telecom research at IDC Asia Pacific.
how do passenger jets change flight paths?"If a passenger does not have international roaming then their access would be rejected by the network and for a period of time that metadata might be stored by the network."."Any passenger who had roaming capabilities or a local Malaysian number - if the plane were over Malaysia - could in theory have been registered on the network if their phone was.We know that the phone number the man called is registered in another city, the press service said.But even this lower altitude is too high to register with mobile towers, experts say."So far, we have not had any evidence of any telephone company of any member trying to contact said Malaysia Airlines CEO Ahmad Jauhari Yahya at a news conference on Monday.How do ocean recoveries work?
"I would assume that the authorities are checking with the mobile operators by comparing known passenger cell numbers to see if there were any pings or attempted or successful network registrations in northern Malaysia or southern Thailand or possibly even Indonesia said Rojas.
