Slashback: StarOffice, Antennae, Handiness

Slashback with more on paying royalties for Web standards, Sun's newest office suite, securing your 802.11 network starting with the antenna(e), and another glove.

Fewer excuses for the "memos and shopping lists" crowd. Sean Lamb writes: "Now that everyone's done slashdotting Sun's servers, I've posted an Out-Of-Box-Experience review of StarOffice 6.0 beta over at Linux Orbit."

Some things just want to be Free. Bruce Perens writes: "HP has made a public statement supporting royalty-free web standards and urging the community to write W3C with their opinion. "

A document on Perens' web site outlines Hewlett-Packard's response to the ongoing discussion of allowing technologies into W3C standards which could require patents on the so-called Reasonable and Non-Discrimatory (RAND) basis. That document reads in part:

"Agreement on royalty-free standards does not end this discussion. The licensing of patents embedded in standards must be compatible with the GPL license that is applied to the Linux operating system kernel, the MIT-derived license that is applied to the Apache web server, and a number of other software licenses. Because of the many thousands of copyright holders who have already contributed to existing products under those licenses, those software licenses can not be changed - the patent licensing mandated by W3C standards must accommodate them."
I hope other companies benefiting from software like Apache, Linux, and any other software which could be hurt by royalty-based standards make similar statements.

Moshe Barr may have laid out how to share a network connection with the neighborhood, but what about when you don't want to or can't afford to? trevmar writes: "BYTE.com has just published an article I wrote about WLAN antennas -- how they work and how to choose them.

  1. Wireless Antennas by Spootnik · · Score: 4, Troll

    Now the major problem is the FCC Certs that we must acquire for our antennas. Most of the manufactures will help get the FCC Cert for the Linksys AP, but, when they do it raises the cost by 75-125%. This Cert is mandatory for installation by the end users, due to the current FCC Part 15B rules. As a professional you may have forgotten about this effect. We and several other manufactures are working on getting the FCC to expand the "Certified Components" rule that was made for computer to cover the wLAN antennas. Till they do, the cost isn't going down much.

    The antennas you are thinking about are Directional. The antennas needed for access points are omni-directional. We have tried to use small yagis and other semi-directional antennas to only moderate success. The only true good results have been from using GOOD omni-directional antennas. Also, the RP-SMA wont fit on most APs, but, I'm sure we can get the RP-TNC on them cheaper, its a matter of demand. The omni antenna set for the Linksys is a new product, if demand goes up, we can lower prices, if demand stays where it is, the prices stay where they are.

    That cute little yagi that Telex makes will make a great client antenna for indoors...

    Now, we have been able to acquire a contract with MaxRad to make antennas for us with RP-TNC connectors, FCC Cert, up to 5dbi that will screw onto the back of the access point. This will make a nicer and **cheaper** antenna, but it will not be as good as the dual 6 and 8 sets, but it will make an acceptable "consumer" grade antenna. Don't think we don't evolve, the main reason we started making the Linksys config is due to consumer demand. The Linksys specials are only about 3 weeks old, it takes a little time to get the certs shoved through the FCC! For now, whoever needs a legal antenna set for end user install, we have the commercial grade Linksys antenna sets.

    We have been making commercial grade antenna kits and wLAN hardware for some time now. Soon, the 802.11 standard for 5.8ghz will hit the streets, This is going to put most of the consumer gear @ 2.4ghz and the commercial gear @ 5.8ghz, which will have the effect of causing the 2.4ghz antenna prices to go way down.

    Another problem is that no matter how cheep we get these antennas, they are always going to be a niche market. Economy of scale isn't going to hit till over 100/week antennas are made, which is an amount almost = to the production of the linksys WAP11.

    As a professional, you posted links to antenna sites with antennas ment only for instlation by professionals. You really need to warn people about the FCC issues with this, as most dont even know the diffrence. Big fines await the unknowledgeable...

      My tutorial was meant as just that - a tutorial. I did not resort to scare-mongering, and I did explain FCC issues.

      You are talking about the licensing situation facing a manufacturer, and the regulations apply differently to those marketing and selling WLAN antennas and those installing them.

      There are thousands of people out there buying WLAN antennas, even on Ebay, without any knowledge of what they are doing. I am trying to increase that knowledge-base so that their actions can be based on real information, rather than merely a raw specification.

      My aim was to let people know what the technical issues are, and what advantages WLAN antennas can bring.

      I did not cover only directional antennas. In addition to theoretical discussions on omnis, I linked to a high gain, non directional, horizontally polarized slotted waveguide omni antenna.

      Please tell me more about the "big fines" which await the unwary public. My research did not uncover any such problems. I would love some pointers to case histories that would allow me to decide whether or not I need to issue corrections and disclaimers to correct what I have written.

      If you transmit radiation in violation of goverment regulations, you can be fined, and if the radiation interferes with other equipment you can be liable for all losses suffered as well as punitive damages. If you interfere with something like a telephone microwave link or a radar, the losses can easily run into the millions of dollars *per hour*. If the interference is willful or reckless, you can even be sent to prison. If the interference is to medical equipment, you stand a good chance of being charged with murder (a lot of medical equipment is RF sensitive, and hospitals use a lot of wireless telemetry which might not be life critical but you won't be able to convince a jury of that).

      Your advice regarding disassembling a piece of equipment, removing its integral antenna, and soldering on an SMA connector is poor. The engineer who designs such a piece of equipment is free to choose any impedance for the antenna and RF power amplifier. (Note for Slashdot audience: When the antenna is removable, it is conventional to use the standard 50 ohm impedance. There are numerous catalogs full of 50 ohm connectors, cables, filters, pads, amplifiers, detectors, etc. There's nothing magic about 50 ohms, it's a pure convenience issue. Like using RJ45s for Ethernet.) The design process is often easier, and the resulting circuit cheaper, if the engineer uses an electrically-convenient impedance instead of being a slave to 50 ohms. Your 50 ohm cable stands a good chance of creating an unacceptable VSWR (voltage standing wave ratio, a measure of the power being reflected back into the amplifier). This can destroy the amplifier or cause distortion, and distortion will get the FCC chasing you. At the very least, I'd cut the RF section off of one and hook it up to a good RF network analyzer and make sure the impedance is 50 ohms. (Network analyzers cost on the order of $1,000/month to rent, or $20k+ to buy, so this isn't a casual thing.)

      It gets worse: when integral antennas are used, the engineer may design the amplifier to only work correctly when that antenna is connected. Since the antenna is permanently soldered to the amplifier, the engineer doesn't need to make the amplifier as robust, which saves money and design time. When a load with the wrong impedance is connected, such an amplifier can oscillate wildly at pretty much any frequency. A 2.4GHz amplifier could easily oscillate at any frequency from a few megahertz to 10GHz. In fact it is eminently possible for the oscillation to occur only during key up/down and quiet down at full power, so it might seem to work while spewing all sorts of RF garbage before and after the transmission slot. This sort of thing makes the FCC *very unhappy* and will earn you a visit from some rather humorless government inspectors.

      It gets even worse: you are soldering a cable to a board that was not intended to have such a cable. The board may very well (in fact, probably does for cheap commodity equipment) have an electronic noise problem. The board itself is only a few inches wide, and thus is an inefficient antenna, but several feet of extra cable can make a good dipole and cause the noise to radiate. If I was building a couple of these for my personal use I wouldn't worry too much, but if I was doing it for commercial purposes I'd definitely recertify the board + new cable combination (which costs thousands of dollars).

      I would recommend a course of study in practical radio circuit design, and a thorough review of government RF regulations, before you give further advice about soldering random cables to random undocumented wideband amplifiers.

    The author of the StarOffice article is a bit off base about how the XML works. Basically, the document consists of SEVERAL XML documents, images, and fonts all packed into a JAR file (a ZIP file with a maifest file). After you extract these files, you then find that each of these XML documents contains so much info that it makes them nearly impossible to be read by humans! (No VI or EMACS, sorry)

    The upshot of this is that KOffice or some other suite could support these documents very easily. On top of that, the compression makes these files tremendously small. I took a 700K Word document (500 pages!) and converted it to a 100K StarOffice file. Now if that isn't cool, I dunno what is!

    This is possible and practical and we should prepare to do it. However, to have three Internet standards bodies would be a bad thing. What we should really seek to achieve is a situation where:

    • Either
      • W3C commits to not incorporating any proprietary technologies into standards, and
      • W3C opens up its membership to ordinary peoplr, with a subscription for individual members of not more than US $50 per annum

      • W3C winds up and IETF resumes the role of setting Web standards, and

  12. star office by jilles · · Score: 5, Interesting

    I have been reading very positive reviews about SO during the past few days. So, I decided to give it a try myself. Here's an overview of my experiences.

    Let me start by saying that it looks promising, despite some obvious flaws which I will detail below.

    Installation

    I installed it on windows 2000. The installer looks pretty and userfriendly and seems to be doing what it is supposed to be doing in a straightforward way. I haven't tried the uninstall yet (duh) but I trust that will be equally good.

    Compatibility with office

    I normally use framemaker to write my papers but occasionally I have to deliver word documents. Star office certainly supports word better than framemaker. However, I found that it had some trouble with the word documents I had. All of these documents are rather complex and they use tables, crossreferences, images and paragraph styles. I was impressed that the document was successfully imported. However, there were a few errors that though easy to correct would have lead to visible errors if I had just printed them without looking at them. I had a similar experience with my powerpoint documents. Near perfect but not entirely perfect. Conclusion: you will need to revise imported non trivial office documents to make sure everything is the way as intended.

    User interface

    From the point of view of features most of it seems to be there and functioning. However, it is far from pretty. One of the key features of office is that it offers a polished userinterface. Obviously MS has a few graphical designers who know what they are doing. I can't say the same about SO it all looks rather primitive when compared to office (far better than framemaker though :-).

    In addition to the look and feel I found some of the dialogs a bit confusing. Some buttons don't have tooltips and there are slight inconsistencies, especially in the more advanced dialogs.

    Features

    After having played with star writer a bit I would say that I would actually prefer it over word and may even consider to use it as a replacement for framemaker in the future. As mentioned before, I use stuff like crossreferences and paragraph styles quite heavily. The prime reason I am using framemaker rather than word is because word is designed for stupid users and tends to "improve" the deisgn of your document on the fly which is a PITA if you do know what you are doing. Aside from that it's handling of graphics is really bad and you are at a constant risk of seriously messing up the layout of your document. Star office doesn't seem to suffer from these flaws and in addition has a build in literature references database!!!! That last feature (once I figure out how to use it because the GUI is a mess) might pull me over. Also I like the fact that everything is stored as XML and I am looking forward to any add on utilities that rely on this.

    So in conclusion, star office looks very promising. I have only looked at star writer and compared it to word 2000. Word 2000 arguably is more polished and user friendly. In terms of features the two suits can compete even though star writer is lacking some of the popular word features (e.g. grammar checking). However, it also has features that either work better than or are not even present in word (e.g. the bibliography tool).

    It looks like I am going to give it a try but it also looks like I won't be recommending as an alternative to office to less advanced users. If you know what you are doing and are equally annoyed with word as I am you might actually like it (otherwise I recommend you take a look at framemaker). It is not the office killer it is advertised to be but it certainly looks like you could use it for most of the stuff you would MS office for, especially when handling more complex documents. It's biggest problem is the user interface which just doesn't have the same quality as MS office.
