Do i have to configure the antena gain in a controller?

hi, i am using antennas of 5dbi for some aps and 2.2dbi for the others aps. so i would to know if i should configure in the controller the antenna gain? or the controller does this automaticaly?

Do you have it setup on the controller for "on demand" or "automatic"?
You can specify it per AP from the controller if you like , or the let controller do it for you automagically. If your APs are spread out somewhat uniformly in a given area - automatic may be the way to go. If you have APs strategically positioned and/or are using external antennas such as directional patches, you may want to do some tweaking. Try tweaking the power levels on a few APs and see how the other APs in the area react and how the user environment is affected.

  • LWAPP/CAPWAP Antenna Gain Setting - label only?

    When configuring an AP external antenna gain (from a WLC), is the gain assigned purely a label to show its gain, or does it actually wind down the transmitter output by the dB amount that is input in to the gain field?
    For instance, my Tx power is set to 2 (17dBm), and I attached a 2.2dBi antenna.
    My ERP would now be 19.2dBm.
    Does the antenna gain value I enter (4 x 0.5) actually cause the AP to lower its output power by 2.2dB to cater for the fact that I have attached a 2.2)dB antenna and maintain its 17dBm output? (...OK, I know 4 x 0.5 will give 2dB, but lets talk in round numbers)
    So in summary:
    AP tx pwr = 17dB
    Physical antenna gain = 2.2dBi
    AP configured antenna gain = 4 x 0.5 (2dB).
    What is the effective radiated power? 19.2dBm, or auto-lowered to 17dBm?
    Thanks
    Nigel.

    This setting effects the heat map predictions in WCS. It also comes into play with the RRM calculations and with some AP's will be considered for controlling the RF power.

  • Cant configure the node of my Integration Gateway

    So I've been trying to get web services exposed from my test PeopleSoft Installation so that they can be used by another PeopleSoft Installation. After some reading and searching I found that I have to configure the Integration Broker in order to do that. From there I've been trying for a while now (unsuccessfully as you can imagine) to configure the Integration Gateway of my PeopleTools installation. Right now I can ping my Integration Gateway which comes back with...
    PeopleSoft Integration Gateway
    PeopleSoft Listening Connector
    Tools Version : 8.53
    Status:ACTIVE
    and from there I can load the connectors, of which there are 11 different ones. After that I go to "Gateway Setup Properties", log in, and from there I have everything filled out with the following...
    Gateway Default App. Server_
    App Server URL: <the machinename>:<the port#>
    User ID: PS
    Password: <the password>
    Tools Release: 8.53
    Domain Password: <none>
    Virtual Server Node: <none>
    PeopleSoft Nodes_
    Node Name: PSFT_HR
    App Server URL: <the machinename>:<the port#>
    User ID: PS
    Password: <the password>
    Tools Release: 8.53
    Domain Password: <none>
    After that, I try to ping the node but it always errors with the following and I have no idea why...
    PeopleSoftTargetConnector - The appserver may be down.  Check Appserver URL or Domain Password.
    The problem is that I know I have the right URL and that the AppServer is running because I can see it's status in Command Prompt after running PSADMIN.EXE and navigating to the status of the server (not to mention I'm able to log into it). I've also looked at the "Configuration Status" in "Main Menu > PeopleTools > Integration Broker > Integration Network" and got checks on "Gateway Configured" and "Domain Active" but there's an X next to "Node Network Not Configured" which I'm not sure why it's there so if somebody could explain that to me, that'd be really helpful.
    So from "Node Network", I can see all the nodes and can see the node that I'm trying to use for the Integration Gateway, "PSFT_HR", that has checks in the boxes under everything except "Remote Gateway Node". After I click on the PSFT_HR node I can see the "Node Definitions" tab that has the Authentication set to "Password", the password set to what I'm entering with the "Gateway Setup Properties", the "Default User ID" set to "PS" and everything after that (Hub Node, Master Node, etc.) is blank. The check-boxes next to "Default Local Node", "Local Node", "Active Node", and "Segment Aware" are checked.
    In the "Connectors" tab I've tried pinging the node but came up with the same error from before. Also, towards the bottom there's a line that says "This connector does not have properties. Use Gateways Page to setup." where I log in to the "Gateway Setup Properties" again, the same info is used from before, and pinging the node gives the same error. As for the other tabs "Portal", "WS Security", and "Routings" I haven't done anything with them as I never read anything that said I needed too.
    Also, as a side note, every time I try to ping the node the application stops responding even after I click cancel or try to click the "x" on the window. I cant do anything until it times out and gives me the error so if somebody could tell me how to change that or stop it from happening, that'd also be really helpful in saving time with troubleshooting this issue
    I hope this wasn't too long with TOO MUCH information (or quotation marks) but I thought I'd get everything I've got right now out the way since I've tried a lot of different things and may get some suggestions that I've already found/tried up until now. I feel like it's something small that I'm missing (because that's always the case) so hopefully one of you can remedy my situation.
    Thanks a lot for any help/suggestions (even if I've tried them, but I'll try them again in case something changes because computers work that way :/ ).

    Fixed the typos with "machinename:port#" to fit the overall naming convention I used.

    Since you didn't provide the "machinename" I'm wondering if that's your problem... you mention hanging while pinging... that sounds like name lookup or port connectivity problems, as if the gateway is waiting for something to time out in that arena. For communicating to yourself, depending on your config, that setting should match exactly whats in the <PS_HOME/PS_CFG_HOME>/webserv/peoplesoft/applications/peoplesoft/PORTAL.war/WEB-INF/psftdocs/ps/configuration.properties psserver line. Now if you created a domain just for PUBSUB it would need to match the jolt port for that domain (not the WSL). Since your logging in online already, we know the configuration.properties file has a good value, if your trying a different domain, I'd try switching back to using your domain for servicing online requests and try again.
    I recommend looking at Nicolas's write up on this topic, it's very detailed.
    http://gasparotto.blogspot.com/2013/05/integration-network-workcenter-853.html you may need to reference his 8.52 version for some pre-reqs as well but the link is in the 8.53 one. Also look for answers in the log file <PS_HOME/PS_CFG_HOME>/webserv/peoplesoft/applications/peoplesoft/PSIGW.war/errorLog.html (if you took default weblogic domain name). I just went through this process on a fresh demo 8.53 demo install and was able to start pinging the node after only a few steps. they were,
    1. define the gateway
    2. load the connectors
    3. define the default and additional node
    4. verified the PS user was able to logon (originally the password was expired)
    5. set the auth type to Password for the node I was using.
    6. success on ping, interestingly enough I didn't even have PUBSUB processes running yet, node network and active domain both show not configured at this time
    On your node network not getting the green check, look on the Node Network status page just below the title, there is a check box for Secure Keystore Value Defined. Is that checked? If not it needs to be. You probably need to set the secureFileKeystorePassword to your keystore password. The default is still password, you can change this from the Advanced Properties Page link of the Gateway Setup Properties page. Use the encryption tool because the password can't be clear text, it has to be saved encrypted to work. Then go back to the node network page and see if it's cleared up. I mentioned this briefly in a write I did on Unified Navigation http://remotepsadmins.com/2013/03/04/peoplesoft-unified-navigation-with-peoplesoft-applicatations-portal-interaction-hub. Nicolas's 8.52 write up has screenshots and such though he does it prior to showing that it will prevent configuration from passing. I've also seen in properly configured systems you may need to just save this page without changes to populate some data, but that was on upgrading to 8.52, i would expect 8.53 would not need that.
    continuing on, I did exactly what I just mentioned, and I've got a configured node network.
    i just bounced the domain, adding the PUB/SUB servers, and activating them on the Domain Status page. I've now got green lights across the board and I can still ping successfully. I used no domain password, but I also verified that none was set in the psappsrv.cfg file. I just hit the Network Integration Status button on my system and got the Status check successful message.
    Let us know how it goes.

  • I want to configure the 7330 motion controller without using MAX

    I am new to labview and I have a project where I have to configure the 7330 motion controller without using MAX. What do I need to do to get started doing so?
    Thanks for the help!
    nw2labview

    Hi,
    There are several VI's that are included with the motion driver for configuring your controller.  They are located on the function pallete under Vision and Motion>>Ni-Motion>>Axis Configuration.  Using these VI's you will be able to configure your axis.  But why don't you want to use MAX?  If you are new to LabVIEW I would suggest configuring and testing your motor in MAX first before you start programing.  Once you have it working there you may want to look at several of the examples such as Simple One-Axis Move.vi.  I hope this helps.

  • Need info about Antenna gain settings

    I could see that antenna gain setting under 802.11b/g ap showing 0 valu. However, the antenna connected to that AP is AIR-1728 which has 5.2dbi. Please let me know if it shows 0 then will I get the Maximum power ? or do we need to change ito some value to get the maximum of the antenna power.

    Not really, with a value of 0 the WLC assumes a standard 2.2dBi of gain, IIRC.  Putting in the correct value for the antenna gain, allows the WLC to make better power settings.

  • Configure the tcode SCOT and SMTP for the SPM module in the R/3

    Hello,
    I want to know if I have to configure the tcode SCOT and SMTP for the SPM module (SAP GRC AC 5.3 SP5) in the R/3 if I want to send information toe the owner & controller.
    Best Regards.
    Pablo Mortera.

    Pablo,
    This would normally be a basis function. Be very careful as this is not specific to GRC.
    This will impact any external notifications using email / fax etc.
    It will also depend on your version and infrastructure.
    If you have web application servers, you will be able to do a lot more than if you have standard (older) application servers.
    You need to create a node under the INT and assign the appropriate tcp / ip rfc connection to direct it to your email server.
    You will then need to define the types of communications to be sent via that method and any appropriate email domain settings.
    You also need to create and set the appropriate send jobs to run periodically which will then automatically call the rfcs to process the waiting documents.

  • Configuring the Transportation Connection Point in defining Routes

    Dear Friends,
    I have to configure the Route Determination for two customers:
    The Route follows like this:
    Route-01:  Norfolk--> Chicago---> Cleveland
    Route-01:  Norfolk--> Chicago---> Denver
    I have configured everything except I am confusing in configuring “Transportation Connection Point”. This Trans. Connection Point is used for Load Transfer point.
    In Trans. Connection Point there two Tabs called “Reference Customer/Vendor”  wherein I can give the number of the customer so that while creating Sales Order the Route will come automatically. and Reference Shpng.pnt/Plant.
    For the creating of Transportation Connection Point at Cleveland and Denver I don’t face any problem as in both the cases only one customer is there because of two different customers.
    But in the case of Chicago and Norfolk how can I give both the customer numbers so that while creating Sales Order the Route should appear automatically.
    Could anybody explain which factor triggers the Route to appear automatically while creating the Sales Order?
    I have to use these Transportation Connection Point in defing the "Route Stages".
    I will be thankful to all of you,
    Thanks in advance,

    OK. The 6.0 version no longer has a printer configuration that I could find. You might try Printer Sharing in the Sharing preferences.

  • If I have two Root CA in the same Domain, Do I have to configure two seperate locations for the CRLs

    Hello All
    Can someone please help me with the following question :)
    I asked the question, can you have two Enterprise Root CA in the same AD domain. This question was kindly answered by Paul
    here  the answer was Yes.
    As far as I believe the two important aspects from a client point of view (e.g. IE on Windows 7 PC for example) are
    1: Public key of the CA (e.g. the CA cert published in AD and therefore downloaded to the X509 store on your PC)
    2:  CRL (published via LDAP (in Configuration partition of AD), HTTP/S or File Share)
    I believe as long as you have access to the above two you can turn the CA off if you want.
    I believe the location of the CRL is detailed in the CDP which is detailed on the Certs issued but a given CA, so the client can look in the Cert and see what it states about the CDP and thereby get the list of revoked certs.
    If all of the above is correct?
    when I add a second Root CA to the same Domain, do I need to use a CA setup file (e.g. the text file, I believe with a .inf extension) to tell the CA setup routine to place its CDP at a location other than the  default location in case it overwrites
    the existing CRL at the default location. Basically I do not want to overwrite (delete) the current CRL when installing another Root CA or does the fully qualified X500 name of the CDP include the CA Name (and therefore be unique) and it will not over write
    the original?
    Thanks All
    AAnotherUser__

    > I believe as long as you have access to the above two you can turn the CA off if you want.
    Enterprise CAs are not intended to be offline. Therefore, you should not turn off them. If these root CAs issue certificates only to subordinate CAs, then you should consider to implement offline Standalone (not Enterprise) Root CAs.
    > I believe the location of the CRL is detailed in the CDP which is detailed on the Certs issued but a given CA, so the client can look in the Cert and see what it states about the CDP and thereby get the list of revoked certs.
    this is correct.
    > to place its CDP at a location other than the  default location in case it overwrites the existing CRL at the default location
    no, CDP locations should be defined in the post-installation script.
    > does the fully qualified X500 name of the CDP include the CA Name (and therefore be unique) and it will not over write the original
    yes, LDAP URL includes CA server's NetBIOS name to differentiate between CAs.

    Re: Anyone still having IOS 6 wifi issues?
    created by mpa9366 in Using iPad - View the full discussion
    Having done a lot of reading today and having found a very good online tablet magazine (will post link tomorrow) there seems to be a few tech bods onto the problem.
    The magazine I was reading identified wifi problems within hours of the ios 6 release and have been analysing since then with almost daily updates - the story seems to be:
    The apple authenthication transmission is normal, it should slip through event prior to a full handshake with the host network being completed - however if not authenthicated then apple will not permit the device to connect (kills the connection) this is designed to protect apple from counterfeiting. So thats problem 1 if you dont receive a token from apple.
    Problem 2 is that ios 6 only supports ipv6 (the new ip protocol) whereas outside silicon valley a large proportion of routers modems etc are still ipv4 protocol.
    So youre locked into ipv6 in a world where ipv4 devices are everywhere and apple have not allowed for the ability to handle both protocols. This is like GM telling you your car requires an upgrade, everything will improve etc and as part of the upgrade fits a fuel cell motor and stays silent when their upgraded vehicles are simply parked up because they cannot get fuel.
    A very basic expectation would have been dual protocol handling - we know the HW supports ipv4 as all wad fine on ios5.
    So its going to be hit and miss with networks - more hit than miss in techy areas like silicon valley, but more miss in places like where I am - a small town in rural Switzerland.
    Only apple can fix this with a patch to enable ipv4 protocol handling.
    There you go. you just need to buy a new router, I'm sure Apple has one for sale, cause it's not there fault for sure.
    Wonder why people start to migrate to other devices ?

  • TS1398 My iphone 3G only gets wifi if its within 1 ft of the router. I have had the antenna replaced but its no better.

    My iphone 3G only gets wifi if its within 1 ft of the router. I have had the antenna replaced but its no better. I have restored to factory through iTunes but still not working. 3G signal is good

    Try these steps. Check to see if your router has a firmware update. Go to the manufacturers website and check. If so, install. If not, reset the router. Disconnect from power for 30 seconds, plug it back in. Wait for it to boot up and then check your wifi.
    Do a reset on the phone. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. After the phone restarts, check wifi.
    If none of this helps, then make an appointment at the Apple store to have the hardware checked. If it is found to have a hardware defect, they will more than likely replace the device. Remember the final call is Apple's.
