More info needed about using wifi in high reflective enviroment

I am looking for documents about using wifi in highly reflective enviroments: rooms with aluminium floor, walls and ceiling en very little materials that absorb rf. (cleanroom enviroment)
Any hints are appreciated.

Thanks for your reply Mat,
The cleanroom enviroment (ASML semiconductor industry) is a large room about 30 * 60 meter and 7m high. In this room are smaller cabinets (about 20) where the actual work is done. Here you can see some pictures:
http://www.brecon.nl/images/brecon_brochure.pdf
In full production there are about 120 engineers working with their 802.11b/g equipped laptops.
Every wall, floor, ceiling, door is made with aluminium sandwich panels. We have major troubles getting a reliable wifi enviroment, and also DECT and GSM telefony is hardly working at all.
Right now we have 10 AP's is the large room, and we are contemplating installing 1 AP in every cabinet with low power setting and using attenuators. We are also considering the use of leaky coaxial cable.
Migrating to 802.11N is not really an option since the clients are b/g equipped.
I will upload a plan soon.

  • Help needed about using wifi

    Please can somebody tell me in words of one syllable exactly what I need to start using an ipad for surfing the internet?  I want to use it to access web pages while I'm out and about.  Do I need a contract with a phone carrier?  Does it need to be a mobile phone carrier?  Could I use my landline number if I have broadband access on that?
    I just can't work out whether I can use the ipad straight away without doing anything or whether I need to involve a mobile or landline/broadband supplier.
    Please help - I'm soo confused.

    a Local area network also called LAN network is what most people use in their house
    it's cables you connect 1 or more computers to get Internet and  access files from eachother
    wifi id 100% that!
    just without the cable
    you have wifi router with a password on
    you go into the settings on the ipad and choose the wifi router name on the list and type in the password
    and you're able to go online
    if you are not within reach of your wifi network you need to reply on public wifi networks if any are aviable where you are at the given time some would be free some would require you to pay them for service
    you only need to contact a phone carrier if you don't wish to use wifi because you have an ipad which along side wifi support 3g internet then you need to contact a carrier and get a micro sim and a contract
    if you already have an mobile phone which qualify as a smart phone you may be able to use that as a wifi hotspot to get on the internet using the phone but in some places this require you to pay extre to your phone contract

  • How do I find out my keychain password? Need more info fast about this

    My computer started to get really slow, so I looked what I could do to make it faster again. After searching I found that the safari content was high and that I should delete it to make it less laggy and slow. Long story short I ended up deleting my saved passwords on safari...Looking into more info, I found out that I needed to get to Keychain Access. I got to Keychain access, found all the passwords.
    My question..
    •How do I get them out of Keychain?
    •If I end up needing my password for Keychain, how do I find that out? I have the like start up CD, but I dont remember ever making a password.
    •And if I do retreive my Keychain Password some how, will that delete everything stored in Keychain? I would have just tried it, but its a lot of passwords I CAN NOT lose...
    Please help :/
    Thanks!

    Never mind the screenshot.
    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • FOR HMARKOVA! HELP! More info needed!

    Hi, Helena! I was wondering if you could give me more detailed information about how to use arguments within two modules. I've just read your explanation!
    I want to connect to modules, I want to select a customer from one module called clients, and then pass that argument into another module called courses. I've created an argument in the called module, if I've understood you correctly this is the module called courses, in the properties I've put defined by clients.name .
    In the calling module clients, in the section
    Called Modules I've added in Argument Passed Values , but I'm not quite sure about what I'm doing.
    Could you explain how to connect two modules using arguments with more details please?
    Thanks ! I would appreciate thaT!

  • More info needed on BC Dynamic menus and using CSS with them

    Hi all,
    The BC Gurus tutorial on Dynamic Menus and how to style them with CSS made no sense to me, unfortunately. The presentation was too rushed and the screen too small to see what was happening.
    In a previous question I found out how to apply CSS classes to BC menus after a bit of a run around.
    I was putting the # in front of the Item ID name and a . in front of the class name and this was not necessary.
    I have further questions though, as I am still struggling to get a BC Dynamic menu to style properly with the CSS I have created.
    1. If you choose CSS as the menu type, can you set the font, background colour and rollover state of the menu items in the Dynamic menu section? Or do you have to style it all in the CSS stylesheet?
    2. If you choose CSS as the menu type, the option to say how the submenu sits under the root menu disappears. So do you need to set this in the CSS stylesheet? And if so in which element? UL or LI?
    3. If you choose CSS/HTML only, how is this different to the option of CSS for the dynamic menu?
    4. If you choose CSS as the menu type and if you set a width and height in the menu item, and then set a different width and height in the CSS stylesheet, which width and height wins?
    5. If you want a dynamic menu to show on an Android phone, do you have to choose CSS/HTML only and do all the styling in the CSS stylesheet? Or should you avoid dynamic menus all together and just use a UL list in the template? (I am doing a responsive fluid grid layout in DW for the template).
    6. I am finding that the dynamic menu I have done, with CSS as the type, does not show and hide the sub menu items properly on an Android phone. Is there a problem with the javascript in Dynamic menus?
    Thanks for any help you folks can give on these questions!

    .pacnew files are only created if you have modified the default (or a change has been made to the config upstream); in both cases, you should be looking to incorporate the changes.
    It seems some new options are being shipped with lxdm: you want those in your config (turning them on or off is a matter for you and the man page to sort out)...

  • Modeler error messages - more info needed!

    Dear Friends,
    I got an error executing a planning sequence of function type  'generate combinations'.
    The system messages on the top section of the modeler  are :
    1. first message :
    "Planning function Gen Combinations ( ended with errors"
    2. subsequent messages are in green (no error) 
    "Context information for the other messages"
    3. Selection for characteristic xyz : Single value 123  (no error)
    :  <  similar ok messages follows >
    2nd Error message :
    "Cannot generate combinations for MultiProvider 'AGGR_LEVEL'"
    this is followed by
    3rd Error message :
    "Cannot generate combinations in step 'xx'"
    When double clicked on these error messages in the modeler, nothing appears to show more error info.
    Could you experts kindly let me know how can I find out what these errors mean , specifically:
    1. For the 3rd error, how can I know what is the step 'xx' about that the system is referring to where it cannot generate combinations?
    2. What does it mean cannot generate combinations for multiprovider? Could you tell me more about what this means in terms of where is the problem?
    Thanks in a advance!!
    regards
    YHogan

    Dear Gregor,
    For a planning sequence using planning function of type 'generate combinations', in general does this process work in the following sequential step ? :
    1. check the filter
    2. generate the combination based on filtered values
    or    is it the other way round?
    I am trying to know where the error lies since it errored so early in the process , about 3 seconds upon executing the sequence via program RSPLS_PLSEQ_EXECUTE.
    I set break point on the class mentioned to no avail as the generate combinations sequence ended with error very early in the process.
    I also set breakpoint on the characteristic relationship class used as well as standard variable exit include program. Also to no avail as the program errored before these stages as none of the breakpoints appeared in debug mode before the error.
    The error message is " cannot generate combinations in step '04' "
    Kindly could you shed more light on this error in terms of what it is referring to?
    Is the problem with master data , filter or characteristic relationship?
    Based on my testing done with breakpoints, seems that its not filter or characteristic relationship error.
    So, does this mean master data error?
    How could master data be having error?
    Most characteristic relationship used are attribute types. There are 2 using classes.
    Thank you in advance.
    regards

  • Need help using wifi on my iPad for computer

    Hi guys sorry if this question has been asked before but i wasn't able to find my answer anywhere so here goes :)
    I just bought an iPad mini and it's awesome i love it. But due to some problems my wired internet connection to my computer is not working anymore and i am unable to buy a new wire for about a week.
    Just wondering if there is a way for me to use the wifi connection on my iPad to connect my desktop PC to the internet as i am unable to stream movies and play games without the wired internet connection. I am aware of the personal hotspot option, however this only allows me to use my  data on my SIM card (i dont have a lot of data to spare so this isn't really effective for me, especially since i will be playing games)
    Your input is greatly appreciated :D

    No, the personal hotspot is your only option.

  • UNIX Executable Files - Additional Info Needed About Zipped Files

    I've tried to go through all of the questions posted so far but each link leads me back to the same three or four discussions.  I have downloaded zipped folders of sound samples.  When they are unzipped the files all have an extra space added just after the extension.  This causes them to be read as UNIX Executable files.  I've discovered the problem but the only cure I've found is to open their info page and erase the space and then confirm that they are aif files.  Is there any way to stop this from happening in the unzip process?  If not is there a method to change these in large groups as opposed to confirming every file one at a time?  I've done about 100 of them but the next folder has 275 files.  Also if the sounds were zipped as stereo files this folder also appears to have separate Left and Right files. I'm not sure if that also could have happened in the file compression process.  The download site has hundreds of folders from different contributors but the file formatting is very consistent.  Thanks for your time.

  • More Info Needed in Message Tracking Logs in Exchnage 2010 MAILBOX

    Hello All
    I would like to understand more on message tracking which was little bit confused for me 2 days back.
    As far as i can know, HUB SERVER is  the main part of the messaging tracking is playing  vital role in Exchange 2010.
    also, mailbox roles too...
    i can see the message tracking logs created in mailbox is only usefull , for  web interface for message tracking is part of the Exchange Control Panel and provides very basic search
    functionality to search for messages either sent by or received by a mailbox, based on the sender, recipients, and subject line.  
    so message tracking logs which is available in mailbox is only user for end users who can perform the message tracking by themself vua ECP without installing EMC. -- AM I RIGHT  
    How will message tracking logs created in mailbox servers .......... will it replicate from HUB servers?  
    so if i have 4 mailbox servers, will all the mailbox servers having the same message tracking logs? or we may get different
    Your information is much valuable to better understand on MT

  • Info needed about PU12 transaction

    Hi,
    I am making modifications in a User Exit which is providing data to a file defined for Interface format ZTE1 through tcode PU12 interface toolbox.
    So, my question is what is this tcode used for ?
    And if my changes include making modifications to the file structure by including extra fields and deleting some,what are necessary steps i need to do to ensure same changes are reflected on PU12 side.
    I hope my question is clear.
    Ask me in case of any doubts.
    Please Guide!!!
    Answers will be rewarded.
    Regards,
    Rohan

    Hi,
    The purpose of PU12 is to create interface format for data export to a third party system.
    The interface format forms the basis for data export. You use the interface format to determine which HR data should be selected and how this will take place.
    You use the interface toolbox to create a program based on the format you have defined. You use this program to export the data.
    You can try this link for improvements in this T Code from 4.5A onwards.

  • More info needed on MAC address

    Hi,
    I have a post in the same forum regarding a problem I have been having since I moved last week: I am getting a self assigned 169 IP address and can't therefore connect to the Internet. I have been doing many things and nothing has been working...
    However, I am able to connect to a PC without any problem...And I found a way to connect with the Macbook but it's only good until I restart: I use the MAC address of the PC and I change my Macbook MAC address for the one I see on the PC through a command in Terminal and bingo, I can connect (until I restart and I guess take back the Macbook MAC address).
    I don't know much about Mac address so if there is anyone who can explain to me what is going on, it might help me to fix this issue once for all!! It seems like the modem likes the PC MAC address better!!
    Thanks!

    Small world
    -I don't see any actions possible on the MAC address 'page'.
    -Only the Mac is hooked to it (there is only one ethernet socket).
    -In another page (of the modem's web setting page), there is this message:
    Resetting the cable modem to its factory default configuration will remove all stored parameters learned by the cable modem during prior initializations. The process to get back online from a factory default condition could take from 5 to 30 minutes. Please reference the cable modem User Guide for details on the power up sequence.
    ...That's what I should try giving your last comment.
    It's bed time soon in Helsinki but I will post again this week end...Hopefully, it will be to say that it is solved

  • More explaination needed about EJB issues published

    when I read the part of "EJB issues" of the page
    http://otn.oracle.com/products/jdev/htdocs/readme_903Preview.html#viadcm
    I have several questions:
    first one:
    Invalid column name when the primary key in one table is different from the foreign key name. (2514361)
    does that mean that the foreign key in table 2 should have the same name as the primary key in the table 1?
    second one:
    Null pointer exception when an EJBSelect() method is called. (2428884)
    does that mean you can not call EJBSelect in your code?
    third:
    Pure MDB cannot run in an embedded OC4J server but can be deployed to a standalone OC4J server.
    "can be deployed" means MDB can run on standalone OC4J, right?
    last one:
    If a CMR exists between two CMP entity beans with the same Primary Key names than the association table generated is incorrect - Workaround is to make sure that primary key names don't match
    All my entity beans use uniqueId as the primary key. In the association table we are using other name as the foreign key. can I use orion-ejb-jar.xml to explicit mapping to overcome this problem?

    Hi Han -
    I had a further look through the bug database for the numbers you specified:
    Invalid column name when the primary key in one table is different from the foreign key name. (2514361) :
    - the base OC4J bug for this has been fixed in the 904 code line and will be in 904. If this is causing you problems with 903, then I recommend you call Oracle support and log a TAR. They may be able to have the base bug for this backported to 903 as a patch.
    You may also want to try deploying this using the non-association table operation mode. You can start OC4J with a system property of "-DassociateUsingThirdTable=false" which will force the container to use pk/fk columns in the direct tables for 1-M relationships rather than the association table. I don't know if this will resolve the specific problem you have, but it is worth trying.
    Null pointer exception when an EJBSelect() method is called. (2428884) : the base OC4J bug for this was fixed in the production release.
    If a CMR exists between two CMP entity beans with the same Primary Key names than the association table generated is incorrect - try using the non association table operation mode.
    Pure MDB cannot run in an embedded OC4J server but can be deployed to a standalone OC4J server. - I pointed out the area of the JDeveloper documentation where this problem and solution is discussed in an earlier post in this thread.
    Hope that helps you somewhat. You mentioned that you were still having a problem - can you post a new thread which has more details of the nature of the problem, stack traces, etc. so we can look at that separately.
    cheers

    I think port is not involved in STP. Now, I would like to know what will happen if BPDU packet is received on any VLAN sub-interface of this interface. Will it simply drop BPDU packet as STP not running on it or, BPDU guard will disable the port completely ??
