Is my neighbor's 4G LTE Cellspot degrading my service?
For reference I live in an apartment building which has acceptable T-Mobile service as I've gone years without any issues living here. A new neighbor has moved in recently, and I noticed that I have been experiencing worse call quality and more calls have been dropping. Our building has a very spotty internet provider with high ping and slow upload speeds. A few things lead me to believe that my new neighbors have installed a T-Mobile 4G LTE Cellspot. I'm familiar with the Cellspot because my parents live in a rural area and have one in their home. In the past my phone used to display 5G service regularly, now instead it displays LTE exclusively. When stepping outside about twenty yards away from the building my 5G service returns. I also receive better speeds when running a speed test outside away from my building. Inside of my building I barely reach 40 mbs down and usually below 5 mbs upload speed which is important for calls and video calls. Speed and the quality of calls has never been an issue before. But only recently because of this I'm needing to leave my home to make calls. It's frustrating because like I said this is a recent issue and I can pin it to something that's making it worse. I use my T-Mobile service to get away from my terrible internet to begin with. I understand that there is no way to connect to the tower directly because the Cellspot is basically a small tower itself and the phone connects there by default. ¿Cuáles son mis opciones?How secure is T-mobile's service? Is it encrypted?
How secure is T-mobile's service? Is packet sniffing or a man in the middle attack possible on the T-mobile network? I know that most ISPs have a good idea of what a user does on their network. You can typically just use a VPN to enable more anonymity online. But from the signal between a device and the cell tower i'm guessing there can be multiple security issues. Lets say I login to my T-mobile account or bank account. And someone has set up a repeater or fake signal that my phone connects to thinking its the T-mobile service. Would that person be able to see the data being transferred over the network. Or is the signal my phone sends out encrypted not allowing for this to happen. Devices like the 4G LTE Cellspot connects to a customers own router and allows them to broadcast a T-mobile signal using their home internet. Are people that own this device able to see data and traffic from my phone? They could possible configure their router maliciously to look at all traffic coming from a 4G LTE Cellspot device with unsuspecting T-mobile customer connecting to it thinking its connected directly to a cell tower. Another way this device can be abused is the person can limit their bandwidth to the device to unusable speeds but all phones around it will still connect to it because its the strongest T-mobile signal. This would degrade the service and make the T-mobile service around that device practically unusable. I swear I'm not paranoid. Just a student studying security and these questions came to mind. Gracias.
