More Masts.
About x10 to x20 more. Capacity rises just a bit less than linearly, but speed can increase by square law every time cell diameter is halved.
So x16 more capacity and closer to max speed, have x20 more masts. Maybe need x2 channels in Urban/Suburban, but a single wholesale RAN and effectively make every retail an MVNO will double usable capacity on existing masts and allow more channels (needed for very small cells to avoid inter-cell interference).
Small Cells = More capacity and much higher speed.
The time has come, esp with more Browser Centric Intranet, Cloud and Public Internet to seriously look at Linux as a Migration option.
Microsoft has basically lost the plot since Server 2003.
Lock in to Exchange & Outlook non-email functions and then Sharepoint was among the worst Corporate decisions, allowing MS to hold Business customers hostage.
For me MS 1981 - 2014 RIP, avid supporter of NTFS, and NT since NT3.5 (Our first deployments just before NT3.51 Release). One of the most important IT vendors for Business has worked hard to become an irrelevant Consumer Appliance company.
Some more Boutique Companies may go entirely Mac + Linux Servers, but I fear the Mac will be ditched for a larger iPad with keyboard and the Mac "all in one" monitors will also migrate to ARM and iOS. Cost reduction, same end user price and more Apple Control / iTunes delivery etc.
There are old Windows applications I need, I will look harder for Linux alternatives and as final resort a Virtual Machine with XP (no Internet) or WINE.
Currently 2014- 2015 is looking unpleasant IT wise. Win7 and especially Win 8 simply isn't a viable alternative to XP. Still running Skype 3.8 on XP. Skype 6.10 on Win7 using about 90% CPU. This seems to be a Skype Issue since about 6.7
Some applications bought between 1999 and 2010 still in use won't even run at all on Win7, never mind Win8. Often newer versions more buggy, no worthwhile extra features and the upgrade cost of all these is much more than cost of a new Workstation.
Yes, really ...
We had 2.2GHz CPU 1600 x 1200 pixel LCD laptops in April 2002. That's nearly 12 years ago.
so if Moore Law was only 2 years (people often say 18 months and long ago used to say 1 year) for LAPTOPS:
2004 : 1 Core 4GHz, 1G RAM
2006: 2 cores 4GHz, 2G RAM
2008: 4 cores 4GHz, 4 G RAM
2010: 8 cores 4GHz 8 G RAM
2012: 16 core 4GHz 16G RAM
2014: 32 core 4GHz 32 G RAM
Nope, Moore's "Law" was only an observation. Like the grain of rice on square one of a chess board, it was never going to hold true for long. Growth has barely even been linear.
HDD native speed, HDD Capacity, Network copper and WiFi Speed, RAM speed hasn't exceeded linear, in most cases declining improvements.
Full HD display
Enjoy a state of the art viewing experience with the Full HD 1080p display.
Why is the entire industry convinced Laptops are only for Video? I had 1200 lines in 2002.
17" 4:3 screen 1880 x 1410 or so would be an incremental step up from 2002.
Still, it's not as bad a laptop as Berger suggests. But at 13" diagonal 16:9 it's a notebook rather than laptop. On negative, it *IS* stupid shiny screen, no ethernet, possibly no card slot.

One for a large handbag/Manbag?
I'd not buy one for any OS.
The UNUSED useless for anything else spectrum exists to TRIPLE FM spectrum. A £5 (retail) adaptor (running for months on 2 x AA) would add the spectrum to existing FM sets. Some Asian models have covered this range since 1965 and cost less than £25 today!
64 to 84MHz (used in Eastern Europe)
175 to 195 MHz (basically unused except maybe the odd 2MHz of DAB since 1985 in UK and Ireland October 2012).
The ONLY coherent argument ever for DAB has been more stations. This appears though to benefit the BBC and some national networks the most.
No, none of those because Digital Radio of ANY system inherently can't adequately replace portable analogue radio.
DAB particularly (or DAB+) is a bad choice.
I used to believe in Digital Radio. But it's a terrible user experience and as an Expert on designing RF, Digital, Software etc, I can't see how it can be fixed. Never mind the power consumption.
Is really really stupid. Zero understanding of
A) Security. EVERY different site needs its own log-in. A universal Login is stupendously idiotic. Even more stupid than using the same password for everything.
B) Why should someone have an account with an unconnected service. ESPECIALLY "bloodsuckers" like Google, Facebook, Twitter (they are parasites on the Internet, though at least Google is almost a worth while one, like leeches for certain skin disorders maybe ulcers)
I stopped using a major UK media site because of this issue. The guy running it can't see what the problem is in
A) Only allowing Google+ login
B) Assuming everyone that wants to use his site is prepared to sign up to Google+
You can cleverly craft broken formats to break the program* reading the data (simplest is String Buffer Over runs/ Array bound violations).
It's not necessary that the format is MEANT to have executable code in it.
But it must be six years since I opened MS software to view a TIFF from Internet (it a was a multipage Tiff, which oddly most photo editing SW/viewers can only see 1st page). Is the default Windows Image Preview/Printer application of XP and later Windows vulnerable?
(* or a 3rd party library the programmer of the program used)
A pin hole camera is a light proof box with a pin hole (smaller is better, in thinner foil, but then exposure time is longer).
Perhaps printing your own Smurfs is more pointless. I'm baffled why anyone would waste the plastic printing their own or buy one. The whole point is to "blue peter" style recycle something.
The 3D printer has a lot of value in prototyping complex shapes. But Pin Hole camera is just a box.
Just hold it properly.
It's equivalent to a 45" screen 2.4m away held 48cm away, so at 20cm / 8" (a feasible reading distance) it should be usable.
My Archos is 4.3" screen and 800 x 480. So 1920 x 1080 at 9" isn't much higher resolution. However is itactually going to be lower than TV HD resolution?
DAB : needs x6 as many fill in transmitters as FM to avoid holes in coverage
DAB : Inherent delay in changing stations vs FM. Huge delay to acquire a new Multiplex that wasn't stored.
The problem isn't just DAB, "Digital" at all proves to be a poor replacement for AM & FM. Even FM can't do away with AM, AM is only way to have fully national coverage and trans-national broadcasting.
Satellite, 3G/4G, Internet, Cable, DTT can't replace AM & FM either, only complement it.
Most of the problems with DAB can't be solved by using a different Digital System such as DAB+ (likely to only be used to double number of channels, never for more quality), DRM or DRM+ or DMB or LTE-B or whatever.
There is no market for Band II (FM Spectrum) other than FM Radio.
No one else has any plan to close Band II. Some countries have only just adopted it instead of FM on 70MHz band.
Actually they SHOULD have added 65 to 85 and 175 to 195 MHz to FM to triple number of stations. A £5 converter that runs off 2 x AA cells for 1000 Hrs would ad the two bands to existing sets. On - off and Hi-Lo. When off you get band II. On you get BandIII or 70MHz band.
Some Asian sets today and since 1965 tune this whole range already!
Be careful what you wish for.
DAB+ has almost no real advantage, except to allow twice as many stations. All the reasons why DAB is inferior to Analogue apply to it.
I used to be a firm supporter of Digital Radio and DRM & DRM+ in particular. I'm now convinced it's technology for technology's sake. There is enough spectrum no use for Mobile to triple FM spectrum! The FM Band II isn't really much use for anything else.
With the end of Band I & Band III TV (1985 in UK and 1999 & 2012 in other countries) and move from VHF Mobile Radio in "fleets" to Mobile Phones there is absolutely no pressure to save spectrum. Which is absolutely the ONLY advantage of Digital Radio. In every other respect Digital Radio is inferior for portable broadcast.
The simplest is part white and black and rotated by a lever to outer edge at either end. It doesn't need to be hollow, it can clip in to a frame.
But if it has four sides (a rectangular bead) then you can have two mid shades of grey.
We can't do more shades without going to very tiny dot matrix beads at 60dpi or higher as with our minimal parts (starburst) 4 x 3 cells, a part rotated bead would look rubbish and it's too complicated.
I think basically two states is complex enough, on or off. via intermediate mechanical linkage such that only one cell at a time is driven by the 3 x 4 rods from "look up table". The character set wants to be as small as possible. After changing a cell by default the next cell is addressed. Erase can be a plate with rods to engage every bead and push to all white (or all black, which ever is blank)
His (or Nipkow's really) allows about 3 rows of 3 characters max. It also has no memory.
The static mechanical displays (hinged mirrors, flip plates/disks, rotating beads) can even be "read back" and used as memory.
The various Magic Slate & Etch a sketch ideas don't need refreshed but can't be read back.
The spinning disk needs refreshed at least 11 fps.
I think the rotatable beads or flip plates/disks are best as:
1) Ambient light
2) Memory that can be read back
3) Fast erase of whole display
4) X & Y character cell addressable
5) Possible to use segment bar per cell instead of dot array to reduce cell addressing from 5 x 7 to 3 x 4, much faster and easier to make a desk sized display using "starburst" than 5 x 7 dots.
So though a CRT or neon dots/.segments (or even under driven tungsten filaments) and batteries are possible in 1890s, both are actually far more difficult and complex to drive than the bead or flip plate arrays.
But DC Electricity dates from some time after 1798, at least in 1878 they celebrated a Volta centenary in France. (Not sure if his Birth, death or the Battery). I'm too lazy to look it up.
Actually there is even the alleged Bagdad Battery,
Two modern Steam Punk displays with memory ...
Actually modern DLP projectors use an array of hinged mirrors, doing 40 x 20 characters each made of 11 segments (starburst display normally uses 14, but 11 is possible) with mirrors or the eInk concept ( using rotating 1/2 white & black segment shape beads instead of balls of Kindle etc).
So we need to operate 40 x 20 x 11 = 8800 segments (either elongated beads 1/2 white & black or hinged mirrors). The beads need no additional light source, only need two positions, could have four faces, and are very stable.
The first electrical matrix displays may be 1908. Victoria died 3 years earlier?
12 segments need 3 columns x 4 rows . making the 40 x 20 text panel 120 x 80 X / Y multiplexed.
One set of 60 Punched metal cards can do the character encoding for each 3 x 4 character cell. The minimum is to reuse 1 & 0 for I and O (as old typewriters did) and only have one case = 26 + 8 = 34 cards / characters.
We maybe can share 5 and S and also 8 and B reducing it to 32.
Update of entire display is slow, maybe up to 5 minutes if a 1/2 second per cell is possible. Erase would be fast (1/10th sec) as that can be a single operation without character cell. Per cell access perhaps 1/2 second.
Each bead about 1/32" diameter and 1/4" long I think?
I actually have 4 x 3 matrixed 11 segment + dp (= 12) LED panels. Curiously most starbursts are 14, but it looks like a 14 segment. (some segments are tied together).
BTW LED was discovered about 1912 by a Marconi Employee but ignored. They were looking for a better RF detection crystal and a weak glow was of no interest. It was discovered again in 1930s by a Russian killed during WWII.
Victorian CRT (on Continent the Braun Tube) was VERY dim as it was "cold cathode", no heater/filament. It wasn't till after thermionic emission was understood (Fleming and De Forest, in contrast Edison was technically clueless, he was a commercial person) that the CRT got a heater. Electronic TV using a CRT with photo target as camera as well as display was proposed about 1906. Baird was very steam punk with his mechanical TV based on Victorian era Nipkow Television.
The Disk mechanical TV is limited to under 30 lines! or about 12 readable characters. Using stacked plates as a set of 200 to 300 mirrors (the plate edges) then about 20 wide by 20 high text is just about possible.
Aconite (?) gas lamp illumination and mechanical drive is possible. But it has no memory and needs refresh of at least 11 fps. The static beads, hinged mirrors or flip panels all have memory and the beads and panels use ambient light.

I think you'll find it applies not just to G.B. but entire UK. Actually it's an EU directive that UK accepted. Applies in most of EU and some European countries not in EU. Probably though the Laptop only has to work for 2 years. Though claims for losses / injury caused are valid up to 6 years.
Apple already got in trouble in Italy for selling so called "warranties" for inside the two years. They must have been studying PC world/Currys and Argos.
They are CONSUMABLES.
It's bordering on criminal that you can't replace the battery pack. Built in "landfill" feature. My Laptop is 1.8GHz 1600 x 1200
On its FOURTH pack (in 11 years) which is reasonable.
On Average the battery will be two years. Maybe 1 year for 20% to 30% of users.
If the Governments esp. USA did NOTHING, it would hurt "terrorist" Recruitment. The number of people likely to be killed in UK or USA by Terrorists is less than car accidents and other more easily addressed things (Smoking).
US policy has probably increased "terror".
There is an inherent problem with Islam vs everything else. Spying on everyone will not solve that but increase Islamic Terror. How does NSA and GCHQ spying stop Islamic Terrorists shooting up African Shopping Centres or assassinating health workers in in Pakistan.
The solution involves Culture and Politics. Not Sigint and Extra-judicial assassination using Drones.
How much spying by USA and China is though industrial espionage and nothing to do with politics or the so called "War on Terror"?
A high proportion of batteries will be poor before 2 years. What is the use anyway if you can only use 25% of the battery and need to recharge to have decent life? If it's useful as a tablet it will see 80% to 90% discharge per use and the battery WILL need replaced inside 2 years.
Batteries need to be user replaceable.
SSD wears out too. Though not as fast.
I've recovered "Bricked" stuff using JTAG.
I'd call it bricked if average user (actually more likely 9 out 10 users) has to bring it to service centre / shop to get it recovered. Can the guys at Carphone Warehouse or PC World do it? Would the average user know to go there?
How many will get binned?
Well I just ordered the new version of Kindle DX. 1/3rd price of a top iPad, but no competition to a Tablet. It might compete well with paper textbooks, scanned books and A4 PDFs on a 1600 x 1200 laptop. I may save a lot on laser printing. Print to PDF and copy via USB to Kindle DX.
I'll not rush into buying text books till the eVersions are a LOT cheaper than dead tree versions.
No eReader is suitable yet to properly replace Text books. Novels are great. Reference works can be OK if done properly (A PDF of images of scanned book is painful).
Also the regular size kindle is too small for text books. If I get the now re-appeared Kindle DX**, I will test it,
Need easier annotation, better bookmarks*, goto by click on place on bar representing "depth" of book so you can flip into via "binary tree" like search as you would do on a paper one when you know roughly the location but not page number.
*Maybe show the Favourite Bookmarks as icons on a bar representing the depth of book.
BTW, Apple, I designed all this in 1987, so don't bother trying to patent it.
(** is re-released DX a newer screen like Paper White? Amazon site seems vague)
Mines the one with a Kindle paper white in the pocket.
Not move at all. In reality the lack of patches doesn't make much difference to a sensibly used XP behind a firewall.
Surely there is a non-MS alternative too? Not if you have a large investment in old Windows and DOS programs, some of which don't work on Vista/Win7 and perhaps more don't work on Win 8, so the very people that can easily move to Win8 due to legacy baggage perhaps can move from MS. Many people I meet even with Win7 already are talking about Apple OS X or Linux. But the danger with Mac and OSX is that Apple has no loyalty to customers. Where are the Apple Servers today? If Mac and OS X is too much less attractive in Income than a cool styled "notebook" based on ARM and iOS Apple will drop the OS X based Mac family.
For BACKUP Archive, only restored when the SSD or HDD fails tape wins
SS powered off data retention capability of up to ten years.
With suitable environment tape might last a Minimum of 15 years and up to 80.
"up to" is a weasel phrase.
Good luck though finding a working drive in 50 years ...
I gave away my 8" floppy drive to a CP/M enthusiast this year. And the disks :)
In the wrong sense.
Maximise licence revenues and avoid the cost and complexity of actually protecting any spectrum user except high paying Mobile Operators.
Ofcom are more "political" than EU, but it's "Sir Humphry's" politics. Not the wishes of the public, parliament or what is good for the UK as a whole.
The problem in the 1980s was that almost no teacher had a computer of their own or any training.
Today the problem is training. If the Teacher knows nothing about Computer Science and interfacing hardware and electronics, the kids might as well learn at home with a Pi.
The interfacing hardware and electronics is very important or else a cheap tablet or laptop with "Scratch" would be better. When Lego Mindstorms 1st came out I had high hopes of it for schools.
Maths is important to decent computer programming and HW I/O. Schools have difficulty finding people to even teach that.
A Pi can only be part of the Technology Teaching to Kids Solution. The biggest hurdles are the Dept of E. Lack of suitable teachers and commitment of schools.
They don't even do ICT properly. When I gave courses at a Business college for trainee secretaries, the best students hadn't done ICT at school. The ones that had (a) needed to unlearn rubbish, (b) thought they knew it all, so didn't listen.
Mine's the one with Z80 instruction set in the pocket.
