How to view this site: Suggestions on viewing Alan Spicer Marine Telecom Blog

I  thought I would make some quick suggestions on how to view this site in your web browser. There are many web browsers available today on numerous operating systems. There are also many different sizes of computer monitor screens in use. From the old CRT monitor screens to flat panel laptop and desktop screens, many which are very wide screens indeed.

The aspect ratio, like in television, is quite different, depending on what you are viewing this site on. Your web browser may also start out, or you may have changed, the percentage of your desktop that it occupies. If this site appears to you as too much of a skinny stripe down the middle of your monitor screen - you might consider increasing the ZOOM of your web browser. This in combination with Restore down (in Windows the button in the upper right next to the minimize button) may make the presentation of this sites pages more pleasing and easier for you to read.

The main contents (Table of Contents), other than the blog post entries, is at the upper left hand side of the screen and includes:

About, Contact, and Product information buttons which each reveal a page with the relevant information and often with links to other web sites or pages that I have about that item. You would want to miss those items - and where it comes to the products I appreciate any purchases as they help support this blog and they are very good products anyway.

This web site uses Word Press as its software to manage the blog. This is a condensed or smaller version of my main web sites. And it uses more modern navigation than the other sites do. Some people like that better. The other main web sites, however, may contain lots more content (articles, information, etc.) Some visitors come for that - but others are just looking to contact me or to purchase a particular product … or to ask me on board a marine vessel (sail, motor yacht, etc.) to consult or make recommendations for their communications, computer, and Internet systems and devices.

If you are having trouble locating anything - please don’t hesitate to call or email me.

Thank You!

Alan Spicer Marine Telecom had a brief email and web outage today …

Alan Spicer Marine Telecom (ASMT) had an email and web outage that lasted most of the day today. The web sites marinetelecom.net, and wifiyacht.net were mainly affected. This also affected email to these domain names. The problem has been resolved with our web hosting provider and things are back to normal. I apologize for any inconvenience.Since April 2007 marinetelecom.net has had a very high uptime and available percentage. Before marinetelecom.net this site was on telecom.dyndns.biz for quite a few years as well. It ran on my own servers on a DSL connection for most of its existence.* Please resend any email messages that were bounced during this time. And please com visit these two sites if you missed us today.

Thank You,

We all live in a yellow (white space wifi) submarine … a yellow (white space wifi) submarine …

Yep, we all must live in a yellow submarine … or a white space wifi submarine. It’ll be quite the shootout between the hype and those trying to give some reality checks to the situation. If the only tool you have is a hammer, everything starts looking like a nail. Here goes current opinion:

First of all if White Space Wireless (who the hell even said you could call something WiFi already before it exists? WiFi Devices must be certified by the WiFi Alliance! Everyone knows that!) - If it has such a long range - It is not going to be a consumer end-user device or service. It’s going to be a commercial or public system offered (free or pay?) to end users. Can you imagine everyone having a 1 or 2 mile access point in their house? That’s just crazy. Well with small antennas they’d not get near that - but they might get 4 or 6 city blocks though.

Second of all Crowded 2.4 Ghz band - If everyone goes to a new band then it gets crowded too. Now if *everyone* gets on a new UHF band but one with a much more range … then everyone sees everyone else’s signal and everyone interferes with everyone else for an easy mile or two circle. If you want to hear and interfere even further then just get yourself a nice UHF Yagi Antenna. That shouldn’t be hard to build especially with Surplus TV UHF Yagi antennas available. There might even be one in the local trash dump. Or one someones roof that they’d give you. There will also no doubt be UHF omni-directional “all around” gain antennas similar to how such antennas are now available for the 2.4Ghz and other bands. Put one of those up in the air and you get some more miles per gallon, right?

* So here’s another blogs take on this thing: http://wifinetnews.com/archives/2010/09/dubious_about_white-space_overhyped_potential.html

I don’t see how what’s postulated is possible. The TV channels in question are 6 MHz wide. Shannon’s Theorem always wins. Channel capacity is a function of bandwidth mitigated by the level and ratio of signal to noise.

Wi-Fi can use 20 to 40 MHz channels in 2.4 and 5 GHz, and likely 80 MHz or more in future 5 GHz iterations. Without multiple radio receivers, encoding improvements in 802.11n over 802.11g bumped the raw rate from 54 Mbps to about 65 Mbps. Take two radios and 40 MHz, and your raw rate approaches 300 Mbps. Three and four radios and 450 Mbps to 600 Mbps.
White-space spectrum can only be used in 6 MHz blocks. Even with an extremely efficient encoding, I don’t see how one can get more than 15 to 20 Mbps out of a channel. I’ve seen several statements that white-space networks will hit 400 to 800 Mbps.
The high power that’s allowed–4 watts EIRP, the effective power after antennas–is pretty remarkable. Wi-Fi is limited to 1w EIRP, and in the nature of radio waves a 4fold increase in EIRP means more than 4fold improvement in distant reception. Correction: Wi-Fi is limited to 1W of transmitter power, but 4W of EIRP. The greater range of white-space devices will come from much, much lower frequencies, which carry further and penetrate better.
However, my understanding is that by the same token, MIMO is ineffective because MIMO doesn’t work over long distances. It requires reflection over short spaces to provide the multiple spatial paths that boost speed. So by going long, you lose MIMO, and encode with a single radio.
Also by going high power, you lose the advantage of cellular infrastructure, whether for Wi-Fi or 2G/3G/4G mobile networking. The greater area you cover, the more your shared medium is split among users, even in a contention-free scheduled environment, which will likely not be what happens. As an unlicensed band technology, you could be contending with interferers of all kinds the higher power you use and greater area you cover.

(More at the link above.)

* Anyway with all of that having been said … History and People have a way of repeating themselves. But sometimes on a good note. Back in the Telephone Modem days there were “theoretical” limitiations on how fast you could go on a pair of copper phone wires. Both modem technologies with compression and such feats and DSL playing nice tricks with the “above voice audio frequencies” - seemed to somehow prove the (even technical) naysayers wrong by pulling it off. So maybe some companies will pull off the supposedly impossible once again. I’d like to see this all under the “Umbrella Corporation” (ha! ha! ha! Like in the movie Resident Evil?) - well I mean under the auspices of a nice standards body like the IEEE, which does the Eight Oh Two Dot … stuff. It would be nice if whatever comes out was freely available to both the Close Source and Open Source communities. A lot of amazing things do come out of open source … including operating systems and parts thereof that create jobs and small business opportunities for the likes of ME and many many others.

* See: Modem: http://en.wikipedia.org/wiki/Modem

* See: DSL: http://en.wikipedia.org/wiki/DSL

* There’s a boat in Fort Lauderdale called Never-Say-Never. So Alan Spicer, although I may nit pick at White Spaces, is never going to say NEVER about it.

* There’s an interesting blog post on this White Space stuff here: http://blogs.broughturner.com/2010/01/wi-fi-in-the-tv-white-spaces—80211af-task-group-underway.html

“I see white people” … I mean I see FCC White Spaces for supposedly super duper WiFi

OK ok I didn’t make up that white people saying. I think it was actually a black stand up comedian. I’m trying to remember who it was? YouTube has some video references to such a spoof on the old “Sixth Sense” movie - where the kid says “I see dead people”. There are spoofs about the saying as well in scary movie and maybe other movies as well.




Anyway the FCC has now supposedly released some of the old Television frequency space … what has been dubbed “White Spaces”. I don’t know why they couldn’t call it “Black Spaces”. But dats Da Man at it again. Really frequency spaces that aren’t being used … aren’t being broadcasted on .. probably should be considered black. Without the rf signal to make them white. But there is a tendancy to call things that are unused or useless as White-something … as in “White Noise”.

Anyway … PC World, http://www.pcworld.com/businesscenter/article/206173/what_you_need_to_know_about_white_space_wifi.html?tk=nl_bdx_h_crawl

has the story today -

What You Need to Know About White Space Wi-Fi

* Anyway you can go there and read the *hype*. I’m a ham radio operator and there might be a tad bit of truth to this hype … VHF and UHF are used a lot by ham radio operators (and VHF Marine in yachting and boating). VHF and UHF do have some interesting characteristics. VHF will tend to go further outdoors. It’s a lower frequency. UHF has a bit less range than VHF has - but - it tends to go through building structures a little bit better. Kind of like a ghost. But… caveat emptor … let the buyer beware. I guess the hype masters never watched the old Analog TV using Rabbit Ears from Inside of a Home or Building Structure. I seem to remember having trouble orienting the rabbit ears antennas to get a clear picture … I had trouble even seeing white people.

There seemed to be something to do with “Multipath” signals and “Ghosts” … god I keep seeing Dead People - I mean Dead Signals. I’m having fun with this but stay with me … I’m trying to make a point. If little antennas didn’t work on TV’s then - then what makes you think that little antennas are going to work now for a consumer WiFi thing on VHF and UHF????

The antennas for VHF television ranges and UHF Television Ranges are quite a bit bigger than the WiFi Antennas of today. So if this is true get ready for bigger WiFi Antennas on your little WiFi Router box.

Which brings me to another point - I though the reason behind WiFi being on higher frequencies and with lower power (power limitations) was to limit how far it went???? So now we’re breaking that rule, right? Unless they are talking about Outdoor Installations. Rooftop Antennas? Like the old Rooftop TV Antennas? Those are pretty big. Just how many miles can you get on Low Power with all-around (omni-directional) antennas on those bands?

It will be interesting to see how this develops and what comes out of it. You already have interference in the current WiFi main band. It would be interesting to see how “dirty” the airwaves will get with supposedly Longer Range VHF or UHF WiFi Systems.

PCWorld did a story on 32-bit vs 64-bit Windows - and so will I …

PC World put a story (with yesterdays date) on 32-bit vs 64-bit Window (and bit more, and a bit less)

http://www.pcworld.com/article/205885/windows_32bit_vs_64bit_personalize_your_os.html?tk=nl_sbx_h_cbintro

By a bit more I mean that  they cut short on the 32-bit vs 64-bit Windows part and went LONG on the and Personalize your OS sections. They also gave a link to a Microsoft Web Site related to the 32-bit vs 64-bit Windows question:

http://windows.microsoft.com/en-US/windows7/taking-the-mystery-out-of-64-bit-windows

Both of these seemed a bit LONG on the comfy chair home user it’s OK to Use 64-bit Windows theme and a bit short on the technical matter that I like. It’s true that it’s ok to run, these days, a 64-bit version of Windows. With Windows 7 this seems to be quite stable and quite capable of running 32-bit software programs” as well. But what does 32-bit CPU and 64-bit CPU really mean? And what does 32-bit Windows and 64-bit Windows really mean?http://en.wikipedia.org/wiki/32-bit




A video from YouTube (not mine) about 32-bit vs 64-bit

In computer architecture, 32-bit integers, memory addresses, or other data units are those that are at most 32 bits (4 octets) wide. Also, 32-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 32-bit is also a term given to a generation of computers in which 32-bit processors were the norm.The range of integer values that can be stored in 32 bits is 0 through 4,294,967,295 or -2,147,483,648 through 2,147,483,647 using two’s complement encoding. Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory.The external address and data buses are often wider than 32 bits but both of these are stored and manipulated internally in the processor as 32-bit quantities. For example, the Pentium Pro processor is a 32-bit machine, but the external address bus is 36 bits wide, and the external data bus is 64 bits wide.[1]

* The Wikipedia article on 64-bit was NOT quite as nice along the explanation line … I thought it would be similar to the 32-bit one.
Visually viewing a concept very often helps it make more sense to us than just reading words about it. Look at this picture:
16-bits on an Imsai 8080 8-bit computer

16-bits on an Imsai 8080 8-bit computer

This is an old 1970’s to 1980’s era 8-bit computer - but the address space was 16-bits. You can see it! Look at the 3rd row of LED lights on the panel. There are 16 led lights numbered  from 15 through 0, or zero.So if you look at this as if it’s bandwidth, or how wide a chunk of something could be to be processed, then that might be instructive. Grant it this is an 8-bit computer which handles only 8-bits at a time … it was the best example that I had to show you what a 16-bit chunk of memory space would look like - if it hit you in the face
So imagine a computer with both 16-bits of address space and a 16-bit CPU chip, which equates to 64 K by the way, and then lets get better than that! If we had twice that space it would be 16 x 2 = 32-bit.

* A 32-bit computer and address space might look like two of these panels side by side acting as one. But that would NOT just double our processing and memory space by simple addition or multiplying 64K times two as it might seem at first.
Imagine 32 binary digits - 1’s or 0’s

11111111111111111111111111111111

If we put that in our Windows Calculator in: View > Programmer mode we get the following translation into base 10 or decimal: 4,294,967,295 - that’s roughly 4 Gigabytes of address space and 4 Gigabytes of processing chunks capability for a 32-bit system.
Now imagine if we had 4 of these panels side by side with an equally capable 64-bit CPU in our computer. It wouldn’t be just 4 times 64 K. It would be

FFFFFFFFFFFFFFFF in Hexadecimal or 64-bits in a row in binary

1111111111111111111111111111111111111111111111111111111111111111

And again in our programmers calculator this would be oh shhhh Windows Calc won’t even do that!!!! It can’t go that high of a number in decimal.

* I had to go find a calculator online to do this:

http://calculators.mathwarehouse.com/binary-hexadecimal-calculator.php#hexadecimalBinaryCalculator

FFFFFFFFFFFFFFFF, in base 16, is 18,446,744,073,709,552,000 in decimal. Actually I think that online calculator made an error on that as well. it should be: 18,446,744,073,709,551,615. That mathwarehouse.com calculator must have overflowed and rounded the result off as well.

Does any body know what that number is? I might need help myself from some information that I keep at the bottom of:

http://www.marinetelecom.net/page-2.html

* By the way, I just want to say that Gcalc in Linux rocks!!!! It did the above calculation that Windows Calc failed to do perfectly.

gcalc-linux-rocks.jpg

Gcalc Tool in Ubuntu Linux “doing the math” that Windows Calc cannot do.

gcalc-linux-rocks-2.jpg

Gcalc shot #2 - you can it did the calculation correctly!

gcalc-linux-rocks-3.jpg

Gcalc - and into Binary as well…

gcalc-windows-calc-melts-64-bits.jpg

And here is Windows Calc having a meltdown converting 64-bits, all “1″’s or FFFFFFFFFFFFFFFF, into Decimal

But it’s enough to say that a 64-bit CPU with a 64-bit memory space can address quite a bit more memory than a 32-bit one. Some of that address space would be much slower hard drive swap space in all operating systems. The following page gives some more technical details on this:

http://en.wikipedia.org/wiki/X86-64

Windows x86-64 editions of Microsoft Windows client and server, Windows XP Professional x64 Edition and Windows Server 2003 x64 Edition were released in March 2005.Internally they are actually the same build (5.2.3790.1830 SP1), as they share the same source base and operating system binaries, so even system updates are released in unified packages, much in the manner as Windows 2000 Professional and Server editions for x86.

Windows Vista, which also has many different editions, was released in January 2007. Windows Server 2008 R2 and later versions will only available as x86-64 versions.

Windows for x86-64 has the following characteristics:
8 TB of “user mode” virtual address space per process. A 64-bit program can use all of this, subject of course to backing store limits on the system, and provided it is linked with the “large address aware” option.[33]This is a 4096-fold increase over the default 2 GB user-mode virtual address space offered by 32-bit Windows.[34][35]

8 TB of kernel mode virtual address space for the operating system.[34] As with the user mode address space,, this is a 4096-fold increase over 32-bit Windows versions. The increased space is primarily of benefit to the file system cache and kernel mode “heaps” (non-paged pool and paged pool).

Windows only uses a total of 16 TB out of the 256 TB implemented by the processors because early AMD64 processors lacked a CMPXCHG16B instruction.[36]Ability to run existing 32-bit applications (.exe’s) and dynamic link libraries (.dll’s).
Furthermore, a 32-bit program, if it was linked with the “large address aware” option,[33] can use up to 4 GB of virtual address space in 64-bit Windows, instead of the default 2 GB (optional 3 GB with /3GB boot option and “large address aware” link option) offered by 32-bit Windows.[37] Unlike the use of the /3GB boot option on x86, this does not reduce the kernel mode virtual address space available to the operating system. 32-bit applications can therefore benefit from running on x64 Windows even if they are not recompiled for x86-64.

Both 32- and 64-bit applications, if not linked with “large address aware,” are limited to 2 GB of virtual address space.
Ability to use up to 128 GB (Windows XP/Vista), 192 GB (Windows 7), 1 TB (Windows Server 2003), or 2 TB (Windows Server 2008) of random access memory (RAM).

* So that gives you some more information about the memory and memory addressing capabilities with a 64-bit CPU and 64-bit Windows Operating System.

* Speaking of Windows … I’m using the IE9 Beta … and IE9 Beta keeps killing itself while I edit this post. There’s something about this Blog Software and its editor that MS IE9 does not like. It keeps crashing the tab that I’m working in while editing this post. I’m just trying to break some paragraph areas of some pasted content in this post … and the browser tab crashes. So now I am in Google Chrome trying to get this thing finished. Imagine that?

* Anyway along the same lines as this article post - The other day I ran a utility from SysInternals Suite (now owned by Microsoft) - called RamMap and came up with the following information on my system here running Windows 7 64-bit with 6 Gigabytes of Ram Memory:

memory-in-hex-dec-bin.txt

That actually looks like I’m only up to about 36-bits of memory space usage full capacity on my computer in Physical “Chip” Ram Memory. The actual maximum amount of Ram Memory that I could install could actually be hardware (memory slots) and BIOS (The computers “Setup” program built into ROM chip) dependent. But anyway I thought this was all interesting. I hope someone else does also.

* On the programmers calculator:
9B000 - 1000 = 9A000 (In Decimal: 630,784) 630784 / 1024 = 616 K
CFFA0000 - 100000 = CFEA0000 (In Decimal: 3,488,219,136) 3488219136 / 1024 = 3,406,464 K
1B0000000 - 100000000 = B0000000 (In Decimal: 2,952,790,016) 2952790016 / 1024 = 2,883,584 K

Here is a web page that’s crushing MS IE9 Beta…

Here is a web page that seems to be crushing the processing power of IE9:

http://www.apple.com/ipad/

And this one they really aught to fix … because that’s the competition, right?

This web page - in Internet Explorer 9 Beta, has scrolling up and down problems. It’s as if it gets “hung” doing something else? Shouldn’t they be able to multi-thread the processing of loading parts of the page … or whatever … refreshing parts of the page? This page seems to flip images on the iPad screen of the iPad product image. You might not be able to scroll down at all while the page is loading parts of it, although the page has already appeared … you don’t appear to have control of it. Later on even after the page has loaded it’s still quite sluggish. You can scroll it down a bit … maybe it hangs up (stops responding) for awhile then it jumps. Then it won’t scroll back up. It hangs again.

IE9 even pops an “apple.com” warning down at the bottom of the browser about “apple.com is not responding”. Later even when I moved off that web page and went to my blog web page … I got a pop up warning that “apple.com quit responding” and it’s searching for a solution. I took a screen shot of that one:

MS IE9 Beta - Apple.com is not responding - ma ma! ma ma! please help. E.T. Phone Home…

MS IE9 Beta - Apple.com is not responding - ma ma! ma ma! please help. E.T. Phone Home…

Bug in IE9 Beta? Images with horizontal white lines through them?

Bug in IE9 Display of Images - Horizontal White Lines

Have a look at this screen shot, See the white lines in the images? then …

Bug in IE9 scrolling the other direction white lines disappear…

Have a look at this one … the lines are gone!

I was looking at some of my older web pages and I saw this happen one time on an image - picture of a Linksys Router. I thought maybe the image was bad … or the image was linked from someone elses site and they scramble the picture. But I noticed it again, on here: http://www.marinetelecom.net/Wireless-High-Seas.htm.

When I scroll up on that page (after scrolling down to the bottom) using Internet Explorer 9 Beta - I get white horizontal lines in the pictures on that page. But when I scroll back down again they disappear. And I was even able to capture it with screen shots of IE8. The lines are similar to the old Television Set problem … if something was wrong in your TV you might see “horizontal retrace” lines.

Which  this article: http://www.eetimes.com/design/other/4013015/De-interlacing-video-basics  tells about.

And this picture shows

Could these be interlaced images: http://www.google.com/search?source=ig&hl=en&rlz=&q=interlaced+image&aq=f&aqi=g1g-m2&aql=&oq=&gs_rfai=

and there’s a bug in IE9 related to displaying them?
