Prime Infra 2.1, AP Auto Positioning

Hi Forum,

 

Ive a situation that our site needs to assign the AP (Access Point) into the existing NMS (Prime Infrastructure 2.1). ive already built the floor as the figure below. so ive many AP on site, how could I make it auto positioning. because, its hundred AP, cant manage all and needs to re-survey if the PI cant have ability to solve this.

 

hope anyone already implement this case. any comment i appreciate that.

 

regards,

Hi,You will have to place APs

Hi,

You will have to place APs on the MAP to tell PI where exactly you have installed AP physically so that it can give correct floor coverage heat map and lot of other stuff.

Hi, Thanks for reply,

Hi,

 

Thanks for reply, according to this situation, i have no idea this APs are placed, so i need PI help to auto position which is i dont put it manually.

 

Is it possible to do that?

 

Thanks before. Regards,

Hi,No. In that case you can

Hi,

No. In that case you can place them anywhere on the map which would generate a wrong heat map and over the time , correct them. How PI would know where APs are located when you don't know ? Just kidding.

Hi, Just to clarify, there is

Hi,

 

Just to clarify, there is a feature called "Using the Automatic Hierarchy to Create Maps" using which you would be able to create maps automatically and assign AP to it using some matching conditions like campus name , building name etc and any AP matching that would be assigned to that AP. But again to make sure that it is correctly placed on the floor , you would have to place at correct location on the map.

Location Accuracy Tool

You can analyze the location accuracy of non-rogue and rogue clients, interferers, and asset tags by using the Location Accuracy tool.

By verifying for location accuracy, you are ensuring that the existing access point deployment can estimate the true location of an element within 10 meters at least 90% of the time.

The Location Accuracy tool enables you to run either of the following tests:

  • Scheduled Accuracy Testing—Employed when clients, tags, and interferers are already deployed and associated to the wireless LAN infrastructure. Scheduled tests can be configured and saved when clients, tags, and interferers are already prepositioned so that the test can be run on a regularly scheduled basis.
  • On-Demand Accuracy Testing—Employed when elements are associated but not pre-positioned. On-demand testing allows you to test the location accuracy of clients, tags, and interferers at a number of different locations. It is generally used to test the location accuracy for a small number of clients, tags, and interferers.

Both are configured and executed through a single page.

Enabling the Location Accuracy Tool


NoteYou must enable theAdvanced Debug option in Prime Infrastructure to use the Scheduled and On-demand location accuracy tool testing features. The Location Accuracy tool does not appear as an option on the Operate > Operational Tools > Wireless menu when the Advanced Debug option is not enabled.


 

To enable the advanced debug option in Prime Infrastructure:


Step 1 In Prime Infrastructure, choose Operate > Maps .

Step 2 Choose Properties from the Select a command drop-down list, and click Go .

Step 3 Select the Enabled check box to enable the Advanced Debug Mode. Click OK.


Note If Advanced Debug is already enabled, you do not need to do anything further. Click Cancel.


 


 

 

Use the Select a command drop-down list to create a new scheduled or on-demand accuracy test, to download logs for last run, to download all logs, or to delete a current accuracy test.


Note • You can download logs for accuracy tests from the Accuracy Tests summary page. To do so, select an accuracy test and from the Select a command drop-down list, choose either Download Logs or Download Logs for Last Run. Click Go.

  • The Download Logs option downloads the logs for all accuracy tests for the selected test(s).
  • The Download Logs for Last Run option downloads logs for only the most recent test run for the selected test(s).


 

 

Scheduling a Location Accuracy Test

Use the scheduled accuracy testing to verify the accuracy of the current location of non-rogue and rogue clients, interferers, and asset tags. You can get a PDF of the test results at Accuracy Tests > Results . The Scheduled Location Accuracy report includes the following information:

    • A summary location accuracy report that details the percentage of elements that fell within various error ranges.
    • An error distance histogram.
    • A cumulative error distribution graph.
    • An error distance over time graph.
    • A summary by each MAC address whose location accuracy was tested noting its actual location, error distance and a map showing its spatial accuracy (actual vs. calculated location), and error distance over time for each MAC.

To schedule a Location Accuracy test:


Step 1 Choose Operate > Operational Tools > Wireless > Location Accuracy Tool.

Step 2 Choose New Scheduled Accuracy Test from the Select a command drop-down list.

Step 3 Enter a test name.

Step 4 Choose an area type, a building, and a floor from the corresponding drop-down lists.


Note Campus is configured as Root Area, by default. There is no need to change this setting.


 

Step 5 Choose a beginning and ending time for the test by entering the days, hours, and minutes. Hours are entered using a 24-hour clock.


Note When entering the test start time, be sure to allow enough time prior to the test start to position testpoints on the map.


 

Step 6 Choose a destination point for the test results. (If you choose the e-mail option, you must first define an SMTP Mail Server for the target email address. Choose Administrator > Settings > Mail Server to enter the appropriate information.)

Step 7 Click Position Testpoints .

Step 8 On the floor map, check the check box next to each client, tag, and interferer for which you want to check location accuracy.

When you check a MAC address check box, two icons appear on the map. One represents the actual location and the other represents the reported location. If the actual location for an element is not the same as the reported location, drag the actual location icon for that element to the correct position on the map. (You cannot drag the reported location.)

Step 9 (Optional) To enter a MAC address for a client, tag, or interferer that is not listed, check the Add New MAC check box, enter the MAC address, and click Go .

An icon for the newly added element appears on the map. If the element is on the location server but on a different floor, the icon appears in the left-most corner (in the 0,0 position).

Step 10 When all elements are positioned, click Save.

Step 11 Click OK to close the confirmation dialog box.

You are returned to the Accuracy Tests summary page.

Step 12 To check the test results, click the test name, click the Results tab in the page that appears, and click Download under Saved Report.


 

 

Running an On-Demand Location Accuracy Test

You can run an On-Demand Accuracy Test when elements are associated but not prepositioned. On-Demand testing allows you to test the location accuracy of clients, tags, and interferers at a number of different locations. It is generally used to test the location accuracy of a small number of clients, tags, and interferers. You can get a PDF of the test results at Accuracy Tests > Results . The On-Demand Accuracy Report includes the following information:

    • A summary location accuracy report that details the percentage of elements that fell within various error ranges.
    • An error distance histogram
    • A cumulative error distribution graph

To run an On-Demand Accuracy Test:


Step 1 Choose Operate > Operational Tools > Wireless > Location Accuracy Tool.

Step 2 From the Select a command drop-down list, choose New On demand Accuracy Test.

Step 3 Enter a test name.

Step 4 Choose an area type, a building, and a floor from the corresponding drop-down lists.


Note Campus is configured as Root Area, by default. There is no need to change this setting.


 

Step 5 Choose a destination point for the test results. (If you choose the e-mail option, you must first define an SMTP Mail Server for the target email address. Choose Administrator > Settings > Mail Server to enter the appropriate information.)

Step 6 Click Position Testpoints.

Step 7 To test the location accuracy and RSSI of a particular location, select client, tag, or interferer from the drop-down list on the left. A list of all MAC addresses for the selected option (client, tag, or interferer) is displayed in a drop-down list to the right.

Step 8 Choose a MAC address from the drop-down list, move the red cross hair to a map location, and click the mouse to place it.

Step 9 From the Zoom percentage drop-down list, choose the zoom percentage for the map.

The X and Y text boxes are populated with the coordinates based on the position of the red cross hair in the map.

Step 10 Click Start to begin collection of accuracy data, and click Stop to finish collection. You must allow the test to run for at least two minutes before stopping the test.

Step 11 Repeat Step 11 to Step 14 for each testpoint that you want to plot on the map.

Step 12 Click Analyze Results when you are finished mapping the testpoints, and then click the Results tab in the page that appears to view the
