MH370: The authorities are not telling us something!
It has just occurred to me that the authorities have ignored (or seem to have ignored) one very important aspect of this series of events surrounding MH370.
While we have been told that some chinese relatives have made cellular phone calls to some of the passengers’ mobiles, that is then all that has been said on the subject. The calls connected and yet, unless I am mistaken, noone has followed up on this very major issue.
The fact that mobile calls were made (and connected) means that the location of that received call can be determined to within the footprint of a cellular base station which, at most, is a few Km in diameter.
What are we not being told here? There are no ifs, buts or maybes about this. This is a fact. The very base station in any particular country where the call was received (and they are ALL tracked due to the need to route a call through the various networks and switches) is known. So then why has the “line” gone quiet regarding this?
The chinese people who have made those calls and connected have provided very accurate data as to where their family members were (assuming they had their mobile with them, which, wouldn’t it be just the norm if the authorities said they didn’t for some reason or another?).
NEW YORK – Telecommunications experts say the odds that passengers’ cellphone data can help locate the missing Malaysian jetliner are next to zero.
This is an article on Fox News Network regarding the possibility of location using the cellphones.
Locating the mobile phones of the 239 travelers on the Boeing 777 that vanished Saturday isn’t as simple as activating a “Find My iPhone” app, given the speed the plane was traveling, its altitude and the fact it was probably flying over water. Many people assume smartphones to be all-powerful tracking devices. Often police, rescue units and others can use a person’s phone to pinpoint the user’s precise location. Even so, there are large portions of the planet that don’t have the transmission towers that are necessary for mobile communications. In the case of Malaysian Airlines Flight 370, smartphones are unlikely to lead investigators to the plane.
[This very sentence, above, tells us (and anyone who has worked in wireless telecommunications can verify it) that UNLESS the phone is within the footprint of a Base Station, you would not even get a connection. This, therefore, proves (if the families calls were connected to the phones of the passenger family members) that the passengers were within the footprint of a base station AND were not travelling at an altitude of 35,000ft or anywhere near it. Cellular base station antennas as highly directional – there are omni directional antennas but then, being omni, their power is not as focused and there is no way that a phone 35000ft in the air (even 5 or 10000ft) would make a connection – and, being highly directional, they focus their energy DOWN (they are tilted downwards toward the ground since not too many birds have mobiles – not yet anyhow). The signal strength at altitude, then falls off exponentially very quickly.]
Note: Antenna on mast pointing down:
and this is the antenna pattern (basically the power lobes and sidelobes of the antenna. You can see that the power drops off with distance and it is focused into a narrow beam. The last thing a mobile network wants is the loss of masses of power into the sky!
Here’s what you need to know about mobile connections and how they’re used to determine location:
Q: Can telecommunications providers remotely locate a phone?
A: Yes, if the phone is turned on and is connected to either a cellular or Wi-Fi network, says Ritch Blasi, senior vice president for mobile and wireless at the consulting firm Comunicano. Apps like “Find My iPhone” only function properly when a phone is able to receive a location signal from a GPS satellite and relay that signal via cell connection or Wi-Fi to those who are searching for it. [But this is considering apps using GPS etc. It is ignoring the basic, fundamental routing of a call through the network switches and base stations. This comment is talking about consumer-style location based services. A base station coverage cell, as identified by its Cell Global Identity (CGI) number, maps to the radio coverage of a BTS. Similarly an LA as identified by its Location Area Identity (LAI) number , is a cluster of cells served by a single MSC/VLR. A group of LA under the control of the same MSC/VLR defines the MSC/VLR area. A Public Land Mobile Network (PLMN) is the area served by one network operator.]
Q: Does this change when you’re on a plane?
A: Yes, considerably. For one thing, most airlines require passengers to turn their phones off or at least put them in airplane mode before takeoff. [Yes because they interfere but also, at altitude, they are useless anyhow! That is why NO calls were made by anyone using a cellphone on 9/11. A Skyphone maybe but NOT a cellphone. That is why the woman – I forget their names now – who was meant to have called and spoken to her Dept of Justic husband, in fact didn’t. Even the FBI confirmed this, which means her husband is a liar and that is one monumental lie he told because it was her call that started the whole story about men with boxcutters and yet the call NEVER took place!] That means there’s no connection to a cellular network, says Blasi. Even if some passengers left their phones on during Flight 370, it would be tough for their phones to connect with a tower given the speeds planes travel at and the altitudes involved. [Exactly! So then HOW and to who and where di these members of the passengers’ families get a connection? Because, somewhere, the plane was on the ground! Again, absolutely no ifs buts or maybes about this. These mobile phones were within site of a base station located on the ground]
Q: What about flying over the ocean?
A: Flying over oceans reduces the odds of a connection even more, since there just aren’t cell towers there [Correct and obvious]. Charles McColgan, chief technology officer for the mobile identity firm TeleSign says that while investigators might be able to determine the last cell tower that cellphones had contact with before the plane started flying over water, if the plane was flying above 10,000 feet at the time, the phones on it wouldn’t be able to make a connection with a tower. [I’d even question seriously flying at 5000ft or less and at speed]
“Anyone leading the investigation should check, but it is unlikely that pinging a passenger’s phone is going to find them,” McColgan says. [Yes they SHOULD check. They should be contacting the telecommunications network provider who routed these calls. Have they done it? No, not that I know of. Why? THAT is a VERY interesting question!]
Q: What if the plane managed to crash on land and some people and phones survived?
A: If someone could get a signal, in theory they could make a call. But if the plane went down in a remote area without service, then they would be out of luck. Foreign travel also complicates things. Unless a person signs up for local phone service in whatever country they’re traveling through, his or her phone may not be able to connect to a network, says Blasi, who spent more than 35 years at AT&T before going into consulting. [No, you don’t have to sign up for “local service” – he’s suggesting you need to call a provider for this. No, you just request or ensure you have roaming from your own provider. This is normal and most people have it if they travel at all. There were Freescale employees on that flight and there is no way they would not have had their mobiles roaming if they didn’t also have something like a Blackberry.]
Q: What about reports of people who claim they called the phones of loved ones who were on the flight and said the phone rang several times without an answer, rather than going straight to voice mail, indicating that the phone might be connected to a network?
A: This doesn’t necessarily mean that the phone is connected to a network, is turned on, or is even operational. It just means that the cellular carrier’s system is taking some time to look for the phone. [Rubbish! If there was ringtone then the network had located the phone AND it was operational. It MAY have been turned off BUT, nevertheless, it would HAVE to have been in the location of a base station and that network provider will have the details of where (which base station) that call was routed to and on which network if an international roaming call]
Each of the cell sites have their own cell identity. That cell identity is known for every call/connection which takes place in a network because the call made needs to “find” the mobile it is calling before the set up of a connection can take place. If the phone is “ringing” then the network has located that phone!
Q: Is there any hope if the plane crashed in the water and the phones on board were soaked? [Stupid bloody question!]
A: Water and electronics don’t mix, so generally speaking the answer is no.
So, the bottom line is this: The authorities have not, as I understand it, even followed up this line of enquiry and that, to me, is very very telling. There is something they don’t want us to know! There are telecommunications network operators out there who have that information.
Wherever, on the planet, those mobiles were, there is a specific, known, identified cell tower which connected them.
I have now just found this exact same article/interview posted on an Australian new outlet’s page. It would seem someone has been tasked to BROADCAST a message to the world that it is “unlikely” that the mobile phones can be of any use. It is then being rebroadcast as “fact” while missing the entire point – the mobiles connected! Someone is trying to subdue this issue. That is quite clear. While the authorities have not even followed the scent! What you have is some half baked “specialist” saying it would not be useful – that is total rubbish! – but the airline and investigative authorities have not even suggested they are looking into it! Now why would that be? People say they got a connection and yet the authorities do not contact the telecommunications network operators to follow where exactly the routing of those calls went?
