WTF is... White Space radio networking?

Mage
Silver badge

Re: White Space...WTF?

No, the vacated spectrum is NOT "White space", that's the "Digital Dividend".

So called "White space" is the effect caused by the fact that if C23 for example is used for a Station, it can't be reused at the next city, but at a further city. At the intermediate location you are not ensured any reception on C23. But SOME people may have larger poles and Aerials and get either C23 depending which way it's pointed. The Fantasy of "White Space" radio is the idea that at certain locations you can re-use the in use channel because

a) No-one here is using it.

b) you won't interfere with the further off places that do use it.

Both assumptions are false.

Re: I have my doubts

3G networks use dedicated licensed spectrum Each operator plans their own spectrum, or with a RAN the Network Manager manages the Pooled spectrum.

The Spectrum isn't shared with a Broadcast service. So called "white space" is an illusion.

The "Database" is a clumsy attempt to solve the "hidden transmitter syndrome". Just because this sounds cool, or allows licence free kit or is very clever doesn't make it a good idea.

SFN

You can't do very large regions with SFN. Go read how it works. The difference of arrival of signal from two transmissions can't exceed symbol guard time.

SFN doesn't enable so called "White space". It just simplifies planning at some locations.

Simple Answer

It's a fantasy that will damage TV reception for 100,000s of people.

An evil genie that should never be let out of the box. Apart from the fact that even if done as planned it's a disaster of epic proportions, people will disable the geo database lookup, the data base will be inadequate and people will add too powerful aerials or amplifiers.

We don't need this Yuppie DIY outdoor WiFi. Proper protected dedicated Licensed Spectrum is the only solution that works.

Pragmatic

Most of Apple's patent's are either fluff or else really Registered Design (more about Copyright, look and Fell) rather than real engineering as most (all) of the products use no custom parts beyond the case (The Apple CPU is just a variant of Samsung SoC with ARM core).

Software, GUIs and Look and Feel ought only be be copyright, never patents.

HD?

1920 x 1200 may be HD on a 24" TV screen but not on Computer.

You need roughly 3000 x 1700 pixels for a 24" Widescreen to have the resolution of 1600 x 1200 15.4" screens ten years ago.

Nice product though. But a trifle pricey for a low resolution computer monitor and resistive panel, though of course it's a bit more than both.

Tick-like banking Trojan drills into Firefox, sucks out info

Re: Correction - firefox on MS's rubbish OS's

You are making assumption that the user doesn't install something that carries this.

Also it uses remote configuration, so likely needs no write access once the user has installed whatever carries it. Assuming it's really a Trojan in original SW sense of the word.

What is wrong with

a) A dock (look at DECT phones and most Handheld two way radios)

Unless it's Fixed ...

Nomadic / mobile / indoor / self install on 3.5GHz is rubbish. Only fixed outdoor/roof aerials makes sense.

Google Imagine WiMax and IBB Ripwave.

LTE doesn't fix the problem.

http://www.radioway.info/comparewireless/

Indoor aerials about x8 less capacity / speed than roof top fixed directional aerials.

Really Fixed Wimax or WiDox (DOCSIS over Wireless) makes more sense at 3.5GHz. So either they are clueless or selling self install "nomadic" "windowsill" kit to save on roll out cost.

Bad investment, bad decision.

The Patents system is obviously broken. Explain to me how much R&D effort there is in this compared with the effort of drawing up the so called "patent"

Apple spends 2% on R&D. How much of that time is spent advising the Patent guys and how much does Apple spend on Patent Paper work?

MS Office isn't important

Libre office (the more popular fork of Open Office) now has Intel backing it and for 99.99% people is good enough.

OK I made up the statistic. But seriously iPad doesn't need Office to Succeed and really there are loads of reason to want Windows on a Laptop/Desktop (hardly any on a Tablet and none on a phone), But MS Office is now WAY down the list of reasons.

My last laser printer was Brother. I wish I had bought the Duplex version. But I needed it in a hurry and the local shops had NO Duplex printers.

Lantronix xPrintServer

Mage

But ...

Why doesn't it have a USB port for a printer?

Or did I miss that?

I have Network Printer servers here. They have connections to drive a printer.

My E65 phone via WiFi can print to any printer on the Network configured to appear as LPR. No extra boxes needed. Of course with the "stock" printer driver I have to emulate an HP laser too.

I can make any linux thing (my Router's USB port) or USB, Serial, Parallel make almost the stupidest printer look like a Postcript LPR device. If I'm really in the mood I can do it on NT4 (even for USB via 3rd party USB stack, but parallel is trivial), Win2000, XP or Win7 too.

So why spend £115 to achieve what almost anything you already have that talks to a printer can do for free?

Or what did I not understand?

1500 lines

For 11.6" long document at 133dpI, you need more than 1500 lines.

Widescreen makes 15" screens too poor on vertical. We need 4 x 3 or even square screens.

The obsession with video is really annoying. Besides most cinema is actually NOT 16:9

To replace a 15.5" approx 1600 x 1200 ten year old 4:3 laptop you now need an 18" machine. Crazy.

Ultrabooks/macair/Ultrathin are a pointless luxury format.

An NT-powered Windows Phone? Not so fast...

Mage

Alert

NT3.51 vs NT4.0

In high reliability situations the NT3.51 lived on quite a while after NT4.0. They blew stability for a measly 10% increase in video & game performance. Yet it wasn't until XP that most games really used NT rather than the Win9x platform.

Since Printer Drivers use GDI also and sort of emulate a graphics surface on NT4.0 a bad printer driver could "BSOD" your workstation or Server. Impossible on NT3.1 to NT3.51.

Ironically the WHOLE NT3.1 was release about the same time as ONLY the kernel of GNU/Linux, I think in 1993.

Why NT3.51? Well, MS "invented" largely fake APIs so Win95 Apps wouldn't run on WFWG3.11 (some only really 16bit). In reality WFWG3.11 had 32bit TCP/IP, 32bit Diskmanager option and Win32s to run NT applications (no named pipe creation was only significant lack).

So they had to add these to NT3.5 and give many a free upgrade to NT3.51. Oh, no version of win9x could create named Pipes either. Win95a little more than all the 32bit options for WFWG3.11 with the Explorer shell.

NT4.0 could use Program Manager and Filemanager and there was a "Technology preview" Explorer shell for NT3.51.

I think Win CE was more a cut down NT with very limited thread/process space (a fixed number) done for a Sega console, and not based on WFWG3.11/Win9x. It was designed for very limited memory with no paging, hence small fixed resource limits rather than dynamic structures. The main stupidity of WinCE PDAs and Phones was using a miniature version of the Windows interface instead of something designed for a small screen. 320 x 240 was a LARGE win CE screen for a long time!

ARM rains on x86 as smartphones outship PCs

Mage

StrongARM

It came from Digital Equipment Corp as part payment in a patent spat.

After a little development they sold most of the ARM stuff to Marvel, though kept a comms SOC with ARM core.

So I wouldn't say they were ever very keen. Their own i960 RISC controller was popular once, but Intel failed to develop it sensibly and do good SOC.

Part of the success of ARM is that it's usually just a small part of an SOC. Even 4 or 5 years ago an ARM SoC might have had the equivalent I/O of an entire laptop motherboard. I used the Samsung 6400 SOC before iPhone and it has the Flash and RAM chips stacked on the ARM SoC all in a 3mm high package. So no Flash or RAM PCB traces or PCB footprint. Intel still don't have an SoC with all the I/O of that part (inc Graphics) low enough power to stack even one other chip on top.

Ofcom needs you... to carve up 37GHz of spectrum

Mage
Silver badge
Boffin

Perhaps a mess

But guess who is responsible and will make it worse.

It's not just about the "price of kit"

1.4GHz to 2.5GHz is progressively poorer range and Indoor penetration.

2GHz to 5GHz is progressively no use for Indoor penetration

3GHz to 10GHz is progressively more line of sight (LOS).

8GHz to 86GHz is limited to LOS point to point links or very short range.

There are multiple bands from 1.4GHz upwards for Satellite, Astronomy or High Altitude Platforms, governed by International Treaty. Ofcom and FCC may think they can, but in reality they should not get "creative" on these.

S, L, C, Ku, Ka etc bands.

2.4GHz and 5.8GHz are pan European Licence Free. "Free for all"

1.8GHz., 2.1GHz, 2.3GHz 2.5GHz, 3.5/3.6GHz and 10.2GHz 10.5GHz are Pan-European Mobile phone, Mobile Data or Fixed Data.

1.9GHz Pan European DECT

Most of it Ofcom has to do the same as rest of Europe. They are too interested in minimising their work and maximising their revenue. Not enough interested in Spectrum protection or the Consumer or value of National Infrastructure. (PLT /Homeplug / CE mark enforcement on CFLs and SMPSUs ?)

Why Start at 1.4GHz rather than 790MHz?
