1. I have not seen the rising and setting of the sun have any effect.
2. If lightning strikes equipment then, yes it would causes issues. Rain has a detrimental effect on cell coverage which will vary by intensity.
3. Cell towers radios are solid state. Here is a brochure on one

I assume you are referring to the application of this or this technology.

It certainly seems like it would be possible. There would be several obstacles to overcome though. It would be a fun challenge to try and tackle.

As for how long I can't really say. You have two transmission sources that you could use, the first being the tower and the second being the phone. One of those would have to be a known fixed position and the other could fine tune the image and provide some 3d views if mobile. There are some huge issues though. RF propagation can be extremely tricky to model. Every surface and material type has 3 fundamental effects. Absorption, diffraction, penetration. In order to provide a usable model an index of every material type would have to be calculated. Then how do you know if you are dealing with 2 concrete walls or 6 sheetrock walls.

It would be a complicated problem to solve IMO.

Is it feasible to build a radio that can hop channels at 1m/s ala some of the military encrypted radios for consumer use/affordable price?

Second completely separate question is, have you ever had a patent classified or known anyone who has? There are fairly substantiated claims that 5k/yr that get classified out from under engineers and researchers.

Thanks for your post and taking the time to answer questions.

Any suspicions of conspiratorial activity in your line of work?

how do you get a cell phone that is not tracking your location

Do you think something like this is possible:

• blanket spray humans with a nano particle which has a resonate activated processor.

• the container of the particle is synthetic DNA so is treated as such and not rejected by the body.

• then activate the resonate Freq via cell towers in any location.

• the freq wirelessly activates the process breaking down the DNA releasing the contents for a specific result.

• I.e simulation of a pandemic etc.

Phreaking was more popular when GSM networks were prevalent as the technology was more simple and did not require a large amount of equipment. If phreaking were to happen today it would more likely occur because of software attacks on phone.

Not a specific question. I subscribe to some theories that are difficult to substantiate and always want to find knowledgeable people is specific fields and pick their brains. I know a lot about cell phones and RF and figured I would try to help answer any questions people had.

To my knowledge there have been no conclusive studies about cell phone radiation causing cancer.

If it does I will be the canary in a coal mine .

edit: Transmit power is heavily regulated by the FCC in the US. Anywhere that transmit power exceeds general exposure limits there have to be signs posted.

That being said I have a friend who was in the military who was operating a large millimeter wave truck. There was a wave guide that had a leak and he was sitting in about 3000 watts worth of RF soup, he vomited and blacked out before being pulled out of the truck. Cellphone radiation is typically measured in mW. or roughly 10^3 power less than what is considered harmful.

VoLTE is still relatively new in the US. It may be that way in other countries as well.

VoLTE has a lot of complicated network side settings and can be difficult to optimize properly.

What are your impressions of the fake cell towers build explicitly by the government to piggyback signals and eavesdrop on communications?

Are you ever told by your higher ups ‘forget it’?

Do those Faraday cage phone cases/bags actually work?

This could be due to a lot of potential issues.

On the physical RF side there are three considerations. Signal Strength, Signal Quality, and Latency

It could be that you are on the cell edge and the signal strength is too weak. In which case you would need a really good signal quality to overcome it.

Or the situation could be that your strength is good and your quality is very poor.

Imagine a situation in which you and on other person are in a silent elevator talking to each other. You will be able to talk very quietly ( signal strength ) because there is no other noise ( signal quality ). Now imagine some shitty muzak comes on and 3 other people walk onto the elevator all speaking loudly. Now you and your friend have to speak much louder to each other to hear each other over the noise.

There could be to much delay between the transmitted signal and the received signal. This has a lot to do with the clutter around you. Trees, buildings, wild penguins, boulders, waterfalls, etc...

This could be due to the fact that whichever provider you are with hasn't really optimized their network. Most carriers are still in test phase in the US ( at least in central area and on east coast ).

The best thing you could do is visit which ever app store you use and try to find some signal reading apps. You want RSRP ( signal ) or RSSI ( also signal ) and RSRQ ( quality ) or SINR ( also quality ) readings.

That's a bit of a broad question and the answer may depend on your specific situation. What specifically do find that is so poor about VoLTE?
