Re: Hmm...

Both 4G and 5G can use lower spectrum than 2G and 3G. The limitation is the following.

4G (band by frequency in Europe).

450Mhz/700Mhz/800Mhz/900Mhz/1500Mhz/1800Mhz/2100Mhz/2300Mhz/2600Mhz

5G (band by frequency in Europe as of 2021).

700Mhz/800Mhz*/900Mhz/1800Mhz/2100Mhz/2600Mhz/3500Mhz/3700Mhz/26.50Ghz - 29.50Ghz*

*Not supported by every 5G phone on the market as of 2021 in Europe.

3G (band frequencies in Europe)

900Mhz/2100Mhz

2G (band frequencies in Europe)

900Mhz/1800Mhz

Lower spectrum use allows for better coverage but at lower speed. This is the same for 4G and 5G.

There are more frequencies that can be used but have not seen any use in 4G or 5G as of 2021 or allocation by regulators* and those frequencies are not supported by mobile phones either. Most phones support more frequencies then are used in any market for reasons of travel between Europe, North-America (ITU region 2) and ITU region 3 (Asia, Australia and more).

*The reason for this is that spectrum is being used by something else. Military, government, private communication by companies and so on. Fixed links communication and more.

Re: Red dwarf systems are always dead

The owner of the study refuses to release the data for everyone to look at (I've not read anything suggesting the data is pubic for now). The signal was detected in a study funded by a billionaire and I think he might be Russian or something. The project is called Breakthrough Listen Initiative. Here is their website, https://breakthroughinitiatives.org | The Wikipedia page, https://en.wikipedia.org/wiki/Breakthrough_Listen

I wish I would be able afford several 30 meters radio telescopes around the world. But I am nothing but a poor man so that is never going to happen.

Re: The cloud is a scam

@SecretSonOfHG Depending on the hosting provider you either have unlimited traffic or you have traffic limit in the TB's of data. Last dedicated server I was hosting on had 25TB data limit.

Re: Bad coverage limited to UK?

If you have not been in Iceland since the late 1998 or about that time then I understand why you think Iceland still have bad coverage.

I live outside of Reykjavík and I have for most of my life. The future plan in Iceland is the closing of 2G and 3G networks in next few years to make space for 4G and 5G networks and start of 6G around 2030's.

Re: No risk of signal detection on Earth from the Moon

When I was writing the comment it was meant as FM and VHF/UHF signals from Earth to the Moon. I don't think however that such station would be able to be picked up on Earth if it was broadcasting on the Moon. But radio armatures have been doing signal bouncing off the Moon for few decades, it works but not without a lot of problems and signal pathway problems.

NASA won't have any problems getting signal from the Moon since they can get a signal from beyond Pluto from a 12W transmitter that New Horizon uses at 8 - 12Ghz.

Re: Scaremongering

This is not scaremongering. If you live in the UK prepare your self for the fact that food costs is going to increase. If you travel abroad (after covid-19 has ended), you are going to be required to fill out forms and pay travel visa costs.

Enjoy your Brexit, as it is self imposed lock-in into England. Scotland is leaving England soon to rejoin EU.

I doubt the story above

I have to doubt the story above because best I can see on Backblaze website there is no form to add an address. Just the zip code and region in my part of Northern Europe. I recently started to use them again after a time period of extreme being broke. That might still not be over because of incompetent politicians in Iceland. But that is outside of this topic.

I also find it strange that you can't provide a case number since most people today use email services that store email for what amount to forever in most cases unless manually deleted from the inbox.

-- I got a title too long error message when I replayed to the above comment. I don't know why that happened since other people have been using that same title without any problems.

Re: Depends on your definition of North

You can use your old VHF antenna on your house to get DAB/DAB+ signals. It has better reception than indoor antenna any day. The old VHF (channels 5 - 13, only ch 3 to 12 where used for analogue television) are now used for DAB/DAB+ radio. It looks like that the bandwidth for DAB/DAB+ in Mhz is just 1,712Mhz and that is why there are so few and poor quality in both DAB and DAB+ channels. Normal DVB-T and DVB-T2 channel is 8Mhz and supports several HD channels or one 4K channel.

I don't know if DAB3 standard is on the way. I doubt it though since IP radio is making its way in the world.

Re: Can anyone explain ...

Faroe Islands are not part of the EU. As they are independent nation in the Kingdom of Denmark they have some chose in the deals they make with other countries.

Re: Visiting multiple Schengen countries

You can be dismissed at the border of an other Schengen country inside the Schengen area.

"[...] If you intend to visit several Schengen States and the stays will be of equal length, you must apply at the Consulate of the country whose external borders you will cross first when entering the Schengen area. [...]"

"[....] Your short-stay visa does not automatically entitle you to enter the Schengen area. At border or during other controls you may, for instance, have to provide information on your means of support, how long you intend to stay in the Schengen State, and why you are visiting the Schengen State.

Equally. Visa permit is going to be required for EU citizen to enter UK from 1st November 2019. I don't know what the visa policy of the UK is going to be for people from EU/EEA. If they have any visa policy. I am not sure they have a visa policy.

Then you have to install some type of Linux or a *BSD to stay secure and private at the same time. Added benefits include no licence headache and related issues.

No problem for me. I am not using proxy, vpn or anything of that to access the internet.

Re: advance its goal "to develop embodied AI systems..."

"Skynet" was here five years ago. You don't keep up with what is going on. The end of the world just hasn't happen. Since all that skynet has to do is to wait until humans extinct them self. That's far more efficient than to start a war that creates resistance, uses resources and all that stuff.

Re: @iron

After Brexit, then yes. Today that's a no.

Re: Here's an idea...

Those are already dead stars. This are the leftovers. Just wait 9 billion years and this is going to happen to our solar system. Earth has only 700 million to 2000 million years left and then everything is going to be burned off planet Earth.

Estimation of what is going to happen in the far future.

Re: Let's report every case of this to the ICO

I was not aware that Scott Adams was a Trump supporter. Thanks for letting me know about this. I have done the correct thing (best to my ability to do so) and removed his work from anything I used to follow him on (Facebook/GoComics). I also removed the books I was planning on buying that he had made on Amazon.

I also invalidated everything I had considered worth listening to from him. Because being a Trump supporter is just really (^9) stupid and only stupid people (and evil) support Trump along with stupid nazis.

Re: If governments really cared about the welfare of the people...

There is no shortage of bandwidth for WLAN. At least not on 5Ghz. What is missing is some type of management because people don't know how to manage their wireless hardware.

Re: Backhaul...

The problem here is two things. This is not a back-haul problem. This is that 3G has bad speed because its ancient technology today. Then there is also the issue with distance, speed drops off quickly as more distance you are from the transmitter. At 30 to 50 km distance the best you can expect is good 3Mbps connection. At 50 to 100 km if you get a signal the best you can expect is 1Mbps speed and lower.

Weather is also a factor in this when distances are this great.

Re: What is the purpose of this?

When Windows turns into subscription only. People can move to an alternative. What is missing for ReactOs are more developers and money. Same goes for Haiku OS. Both are alternative to Linux and *BSD.

Re: No VoLTE/VoWiFi on many networks

You are going to get 5G signals before that. The current situation is to clear 700Mhz (this has only happened in some countries) and even go down to 600Mhz (maybe 450Mhz) in next few years. Television and radio is going to IP broadcast networks at the same time, so bandwidth is not an huge issues in the long term future.

Current delay for 4G networks is the use of 2G and 3G networks in 900Mhz band. It has helped that 800Mhz is only used for 4G networks and soon 5G networks. The change of technology always takes time to happen.

In Europe 4G and 4G+ coverage is good in the countries that I know (Denmark and Iceland). Denmark has close to 99% coverage an Iceland has close to 80% coverage (this numbers are just estimates based on the coverage maps that I can access). In Iceland the 4G coverage now is closer to 95+% if only counting towns and villages. Many areas of Iceland have no service or just 2G/3G service due to how remote they are.
