THEY CAN ONLY COME FROM PC'S TABLETS AND SMARTPHONES. SATELLITES DO NOT SEND WIFI PROBE REQUESTS. It cannot be monitored, sniffed or captured with Wireshark and satellite transmissions CANNOT be seen on a plane in the way you suggest. I have *hundreds* of customers out there using this technology. I do satellite broadband and VSAT communications for a living. They would never reach the planet from the satellites orbit. Satellites don't transmit on 2.5 or 5.0Ghz frequency.

The rules and laws in each regulatory domain will cover things like maximum radiated power, frequencies/channels that may be used and so on. There are others but I am not familiar with them. The ones I am familiar with are USA, The EU and Japan. Regulatory domains are the countries or territories that use the same laws to govern wifi. Some devices allow the user to choose the regulatory domain. It means one wifi device to another.Ĭountry string is the hex value for the regulatory domain set by the device manufacturer and will be appropriate for the country the device is shipped to. P2P usually means peer to peer or point to point. Interference isn't a fixed value so probe requests from the same host in the same physical position can still have different RSSI values. Help me to help you my telling me which packet it is in the sequence so I can look at the same one. If you want me to look at the same packets you are, I need to know which packet it is. I DOUBT THERE WERE ANY ACTIVE WIFI ACCESS POINTS ON THE AIRCRAFT.Ģ. ACCESS POINTS SEND PROBE RESPONSES NOT PROBE REQUESTS. UNTIL THAT HAPPENS THE TAG MUST BE 0 BECAUSE THE HOST DOESN'T KNOW WHAT IS OUT THERE UNTIL PROBE RESPONSES ARE RECEIVED. A PROBE REQUEST IS A HOST ASKING EVERY ACCESS POINT THAT HEARS THE PROBE TO RESPOND WITH IT'S SSID. PROBE REQUESTS ARE SENT BY HOSTS NOT ACCESS POINTS.

What are the MAC addresses of your laptop and phone wifi interfaces?ġ. Do you have a phone with it's wifi hotspot switched on? Is the laptop set up to share its wifi connection? Both would cause Wireshark to receive wifi beacons. You are saying that the SSID you can see that is giving you interference is still present on the flight and you are receiving packets from it? That suggests you are carrying it with you.

Which packets are the ones giving you the issue? It's not clear from the capture which ones you are interested in. I can see the interference comes from Satellite. I can see something is not rigth with WiFi packets but I want to know whether anything strange or particular about the For sure there are not beacon frames but what I can see probe request to SSID=Broadcast and for sure there is such SSID on the flight. As result, I received WiFi Packets.Īnything strange of this pcap. I use my Laptop to check whether I can receive Wi-Fi packets or not. In these situations, a cell phone signal booster for home, office, or vehicle can solve your reception problems.On the way flight back from Medan to Singapore at 32000 ft. Low areas around lakes, rivers, and gullies can also experience problems-there is signal, but it’s passing way over your head.ĭense urban areas with tall buildings have a different set of problems: Sometimes the top floors of buildings, forty or fifty stories up, can’t get reliable cell signal because cell tower antennas are aimed at lower elevations. If you’re outdoors, dense forest and hills will reduce or block cell signal. Stucco with wire mesh, metal roofs, logs, and vapor barriers in attics also impede cellular signal, as will a large concrete building between you and the cell tower. Many building materials-including concrete, metal, low-e glass, wood, and plaster-reflect or absorb cellular frequencies, preventing them from penetrating the building and reaching your phone. It’s possible to be close to a cell tower but still be receiving weak cell signal. Physical barriers block cellular transmissions
