A 5G day may come when the courage of cable and DSL fails ... but it is not this day

Mage

5G application

Basically stadiums only. Replaces multiple WiFi. Can use wide spectrum Line of Sight only bands, which are useless for normal mobile.

Also 5G spec isn't even needed for Fixed Wireless (FWA). That uses Line Of Sight and has been in use for over 12 years at high performance. It needs roof top aerials and Line Of Sight, as does ANY 5G FWA better than existing mobile. FWA is only cost effective for rural Line Of Sight that can't be fibred. It's REALLY expensive to install. Also can't deliver the speed & capacity of 200Mbps Hybrid Fibre cable in urban. It only beats rural DSL, but that is actually cheaper to fibre now than FWA if you want more than low contention 50Mbps! The Rural fibre is 1Gbps & lower contention.

potential to make cable and DSL as antiquated and pointless

Sorry, but this nonsense on so many levels.

5G is just Mobile Wireless. Fixed Wireless can deliver up to 16x performance but is MORE expensive than Fibre unless it's Rural 20km Line Of Sight. Fixed Wireless needs rooftop aerials and LOS to get the performance. Mobile, NO MATTER WHAT xG, is limited to roughly 0.8GHz to 2.3GHz frequencies (Physics).

5G doesn't change the mathematics & Physics of Wireless. EVERY other lamp post would need to be a fibre fed femto base station.

Only fibre can make DSL and pure cable obsolete. Hybrid Fibre Cable beats Fibre to cabinet + copper pair (VDSL etc) because cable can manage over 1GHz of bandwidth. A Copper pair struggles to do 0.03GHz of spectrum and slows rapidly with distance over 100m and crosstalk. Cable can manage a 1GHz of bandwidth (certainly over 250Mbps per user) at over a 1km, however for new installs / routes Fibre to the premises is better. It can go anywhere with existing water, electric, gas, sewerage, poles or ditches.

The 5G is an excuse for Infrastructure companies to sell upgrades, Mobile companies to try and replace WiFi Hotspots (fed with Fibre, cable or DSL) with mobile femto cells fed by fibre.

All decent Mobile bases or Femto cells need fibre backhaul anyway.

The 5G is more about integration of services, not faster or higher capacity Mobile, which can only be achieved by treble or x10 number of base stations, no Return on Investment to give better performance as it won't bring in more customers or revenue, only increase Capex and running costs.

Re: Even QR codes are dangerous.

Ages ago I was tempted to put replacement QR codes at all the labels in Tesco veggie section. I noticed recently they are gone.

You mean especially QR codes are dangerous?

I managed to find an app that reads them (and other barcodes) and only decodes & displays, with an option to save it or create a Firefox tab. Most phones seem to open the browser directly.

I despise people using obfuscated short codes (invented for Twitter and no longer needed there?). 1: The short code provider knows your IP, the time, your browser, OS and previous web site. 2: You have no idea what it will load.

Problem is basic design of USB, particularly HID which can inject scripts without storage mount.

Also stupidity of JTAG over USB management modes on some motherboards. ONLY use a JTAG header.

Re: Storage media

Writeable CDs and DVDs are not as long lasting as Flash. The dye fades. You can kill them in days to months left on a windowsill. Pressed ones are OK though the reflective layer might corrode.

An old HDD powered down beats tape, which beats Flash which beats dye based writeable CD /DVD.

The MO disks might be good for long life, last 3.5" size was maybe 250M? Far better than the rubbish ZIP drives.

Earth Final Conflict.

As an aside.

There was a Philips subsidiary that developed a "roll up" eInk based screen. Philips sold it and only does lamps + health now (like 1926). The TVs & audio are two companies renting badges,

Philips Semi -> NXP, sadly about to be devoured by Qualcom.

Unfortunately Amazon bought the Philips subsidiary or the eInk tech, though they don't use it. They buy the actual eink brand (Vizaplex, Pearl, Carta) etc for Kindle.

Sony also had a demo of roll up display, possibly eInk.

Really only OLED or eink with amorphous transistors on a plastic substrate with plastic layers will work. Lifetime may be low. Worrying that newer eReader eInk displays may already be plastic substrate. Yes, less likely to be cracked, but what is life?

Upset fat iOS gobbles up so much storage? Too bad, so sad, says judge: Apple lawsuit axed

Mage

Boffin

Re: RAM manufacturers always used powers of two

Because each extra address line doubles the storage, thus inherently powers of 2. Tape, floppies and HDD have always used the approximate SI based amount based on powers of 10.

The chip makers incorrectly used K = 1024 and M = 1024 x 1024 out of convenience.

I've been buying computers & storage since RAM was 1024 bits per chip and my first floppy drive was approximately 100K bytes. It was maybe a decade or more later that public started getting confused. Really it's not a marketing plot how HDD storage is described. Now the actual random write transfer speed on a multiuser server is another story. Mostly INTERFACE speeds are quoted on the box!

Re: *HORRIBLY* misunderstood by WAY too many.

Gosh, I might even invite "bombastic bob" in for tea!

I bought a new laptop nearly two years ago, with win7. My main one before that was XP from ... 2002! (1.8GHz P4 1600 x1200 screen. WiFi, HDD, upgrades, RAM added). It had Win7, but since I've been using UNIX family since 1985 and Linux servers since 1999, I switched to Linux Mint + Mate desktop. I have a ghastly workstation and a convertible Laptop/Tablet both win 10. I rarely use them except to check Windows horror stories. I may change the Tablet/Laptop to Mint if I figure how to fix screen rotation not rotating touch (or something, I set up an old IBM X201 with Mint and told the owner to only use it landscape in Tablet mode, he only uses in laptop mode anyway. The Waycom pen is nice).

Re: Samsung innovation

There is indeed no real tablet innovation.

Just improvements in price.

No-one has satisfactory solved dual use, a tablet used only for touch (Linux not good), or a tablet used for content creation for a long period with keyboard (optionally mouse). iOs and Android fail as general purpose OS in tablet mode.

Win10 is MUCH poorer than Win7 or XP or Vista in laptop mode. Mac OS and Linux also now superior to Win10. Yet in undocked Touch mode the desktop applications are near useless on Win8 or Win10, only the "toy" stuff for Metro/Windows phone being any use.

What's needed is applications to have dual GUIs. No, Mozilla, I DO NOT want desktop Firefox to behave like a phone app, it's grotesque!

Re: electronic equivalent works just fine with the amateurs

Actually that's derived from Fax, First experimental Fax on wire was in 1851. SSTV is to Fax, what RTTY is to Telex/Teleprinters (from 1928, but also Victorian experimenters). Radio Fax was also in 1930s, at same time as Baird, and transmitted in the USA after radio program close down. Add on printers for existing ordinary radios were sold in USA. The Mechanical TV was also done in USA too as a novelty after normal progam close down, but the radio fax was more practical.

SSTV doesn't do moving images, it's basically Fax.

Re: James. Clerk. Maxwell.

Einstein credited Maxwell. Maxwell was a hairsbreadth from relativity theory.

real father of Radio (though Hertz important). Marconi didn't claim to be a scientist, but an entrepreneur. His main jump was realising that radio range needed and aerial (wire) and an earth(ed connection) rather than a small loop. Later when VHF was possible, loops were used on transmitters. A multiturn loop does work for receive.

Also Maxwell realised how colour photography could be done (though a panchromatic film was some time in the future).

Many other things too.

John Logie Baird

"John Logie Baird

Why?

He basically invented television"

!

!

Not this old chestnut. He DID NOT invent Television. He was successful at raising the profile of it and promoting a dead-end mechanical concept. Electronic TV was outlined in 1905 or 1906. The only difficulty was the camera target. Various people even replaced the receiver disk and later mirror unit on the Baird system with a CRT. He used a near real time developed cine film and scanner eventually when the resolution reached 240 lines. That was later developed for spy satellites for HD and slow transmission.

By 1935 the RCA electronic system had beaten Farnsworth's (his was a dead-end camera target concept). EMI worked with RCA (historic links via Marconi, HMV and Victor Talking Machine Co,) and developed a decent camera for UK.

No country in the world continued with Baird way of doing it.

Re: Margins still not under pressure

It's not as simple as that.

Look at Apple's margins on some volume products. They do have functional competition.

Also the Communications Regulators (Ofcom, Comreg, FCC) don't understand competition. They think it will reduce prices and improve services. It doesn't due to monopolies of coax or local loop of previous incumbents. Mobile is degraded due to splitting the spectrum and not having a single wholesale operator.

Once a particular vendor has more than a certain share or reputation (Intel has both on desktop & server. Apple has "reputation", but not share), then competition doesn't help the consumer much. Prices are never based on cost but on either what the market will bear (Apple) or below cost if the aim is to create a monopoly (Sky in UK 20 years ago, Netflix now) or steal market share (Three mobile below cost for Data).

IMO the USA laws on Copyright are technically illegal in International agreements.

DRM and DMCA are an abuse of Corporate power. We all pay for the royalties of HDCP in things with HDMI. Also DRM doesn't stop commercial piracy, it takes away users rights.

It's a start. However DMCA needs to be killed and DRM made illegal worldwide.

The Corporate grab on extending copyright needs to be reversed too!

Re: Netflix

Netflix has deals with ISPs for them to host Netflix servers. Particularly ISPs offering bundles. Netflix is more concerned about rapid subscriber growth than profit (they have none?).

Amazon is more cautious. They don't have the ISP deals either, hence things like exclusive live tennis coverage falling over.

NO streaming only service should have sport exclusives. Possibly Pay TV should not have exclusives on live sport.
