Comment Re:Infrared Bandwidth? (Score 1) 216

You can easily do more than one bit per second per Hertz. There is no need to go to 1600GHz. 256 QAM gives you 8 bits per second per Hertz, leaving you with 100GHz. Now go 10-way MIMO and you are at 10GHz. Polarize and you are at 5GHz.

Fitting 20 antennas per supported frequency band into a phone is left as an exercise for the reader.

Also, cell phone networks always calculate as if they have precisely one customer per cell. The 800Gbps is shared.

LTE is definitely a generation ahead of 3G. The latency is massively different; 4G feels very different from 3G in the same way that ethernet-over-fibre feels different from VDSL. 4G can actually feel like an OK DSL line. 5G with 1ms latency should be able to compete favourably with low-speed fibre.

(Latency is also why it is laughable that UK providers pretend that they are selling fibre optic broadband. It is a sign of the missing consumer protection laws in the UK.)

Videoing does not help. Almost everyone can drive just fine when drunk; a car has four wheels and generally stays pointed in the same direction if you do not mess with it.

The problem is what happens when something unusual occurs. That is when being drunk gets you and people around you killed. If you are just videoing someone, you are unlikely to catch them in such a situation, and even if you do, it is too late.

I completely agree. In the normal situation. This is not a normal situation.

This is a situation where health is put a risk on a global scale because we cannot be arsed to pay a few thousand ambulance drivers, and so infected people are left at home to infect their community. It is complete stupidity.

Those ambulance drivers are risking their lives every day. The least we can do is pay them their normal wages.

We can't even find the money to make sure that everyone in our own countries are treated without bankrupting them, what makes you think we'd be able to pay another country's medical bills too?

a) Of course we can. Practically the entire Western world has universal healthcare, and the one country which does not pays more than average on health care per capita.

b) We are not talking about actual treatment. Only about finding a few hundred million dollars to keep existing medical personnel paid while governments in the affected countries are in deep trouble.

If Ebola gets to Western countries, a few hundred million dollars are gone in the blink of an eye.

A lot more could be accomplished by just throwing (not very much) money at the problem. Like Sierra Leone where ambulance drivers are only on half pay due to government budget cuts. It is ridiculous that we (first world countries) cannot find the money to make sure that health care workers in the affected countries are paid reasonable wages.

Hint: It has 4. Zeros are significant. If they aren't, you're not supposed to write them. [..] If you wanted to claim "2000 MPH" really meant "between 2000 and 3000 MPH" then it should have been written as "2x10^3 MPH or 2 kMPH

Your proposed nomenclature is practically not in use. Very few people would understand it.

2000MPH has one significant digit unless you can deduce from context that it was measured more precisely.
