4G and 5G are mobile technologies that the worlds mobile communications are based on without which emergency services, industry and commerce could no longer operate.

Thank God we no longer require operators to patch us through to someone or have to rely on "party line" telephone calls

GG is a colloquialism for a horse I believe

Just as a heads up, and I kid you not, in the next 30 years human beings will have chips inserted into their brains to enable people to communiate with each other and the internet without the need to "dial" anyone, type anything or use mice/keypads:) - the technology already exists in its infancy and its just a matter of time!

The lack of a mobile signal is (mostly) down to simple economics: masts are only usually placed where people want to/will use them since this will generate revenue for the mobile network operators.

There is some encouragement from the licensing authority to provide as much geographical coverage as possible but clearly if no one is around there not much need for a mobile mast.

The other challenge is terrain since mobile signals are easliy blocked by mountains and buildings (particularly 5G which has a much shorter range than 4G)

Military communications use different wavelengths so no sensitivity issues there.

The problem with mobile phones isnt the mobile phone or its technology, its simply down to user behaviour. If you choose to have the ringer on your phone turned on and you keep answering it and you have a burning desire to keep telling everyone what you had for breakfast, guess what, your life will be controlled by the phone.

If you manage the phone settings properly its a tool to help not hinder you:)

I find it most useful for sourcing information on demand: give me this anytime rather than how things were done in years ago

Intentional electromagnetic interference is illegal so I wouldnt think that is whats happening.

Unintentional interference by other electrical devices is a possibility but I doubt it because of the power output needed to block a large area.

Its most likely due to environmental conditions : landscape topography, trees, and other buildings that causes the reception blackspot

Chips in the brain in the future? Isn't that what some believe already happens with the Covid jab?
