CROME Site Mapping and Variance Reporting

Features and Usage

Quantum Systems Integrators, Inc. is proud to present its CROME Site Mapping and Variance Reporting for all CROME deployments. Note, this real-time GIS variance reporting applet shares many features with the CROME client's GIS reporting methods. However this applet if focused on high efficincy (low server impact) real-time reporting for very current informaton.

The Site Mapping Window

The Site Mapping Window pops up from the Site Mapping and CROME Variance Web Page. Once the window comes up, it can be resized to any size by stretching the window corners.

The "CROME Site Mapping and Variance Reporting" is a Java Applet and is started by clicking on the "Show Site Map" button.

After the button is pressed the Applet will display a new window and perform the following actions:

A typical initial display is shown below:

The above Applet window is divided into three sections:

Note that the title bar of the window shows the date and time of the latest variance information retrieved.

Panning and Zooming

To Pan around the map, use the provided scrollbars on the right and left of the display

The Map Display has a configurable set of zoom levels depending on the needs of the operator. Typically three to five levels of zoom are provided. These zoom levels can be changed by selecting the zoom pull down choice on the control panel:

Site Colors

Each site on the display is colored one of four ways:

Site Detail

By moving the mouse over a site on the map, the "Site Detail" line will show the information about this site:

The line shows, in order:

The Control Panel

The left portion of the Control Panel includes a switch list (for iDEN this shows OMCs), variance list, various check boxes and pull-down choices that affect what is shown on the map.

The variance list, check boxes and pull-down choices are discussed below. The right portion of the Control Panel, which shows the "out of variance list" of selected sectors/carriers, is discussed in the section below.

Selecting OMCs

By highlighting and un-highlighting the items (for iDEN OMCs) in the "switch list", the sites associated with those OMCs are either displayed or hidden from the map.

Note that in the some large scale demos, we are not providing this GIS feature for all geographic regions. All areas can and will be added if/when a potential client running a demo purchases or leases the CROME product.

Viewing On Air and Off Air Sites (foreign database filter)

A foreign database maintained by one of our demo clients tags sites as either "On Air" or "Off Air". The "CROME Site Mapping and Variance Reporting" tool hooks into this data base via two check box controls. By checking and un-checking On Air Sites and Off Air Sites, the sites that are marked as On Air or Off Air will be displayed or hidden from the map accordingly.

The On Air information associated with each site (or iDEN EBTS) currently comes from a non-Quantum foreign database known as TOED (by the client), and is updated daily by client staff. Other filters and data sources can be easily integrated into this GIS system

Viewing Out of Variance Sites

By checking and un-checking Out of Variance and Operating Normally, the sites that are Out of Variance or NOT out of Variance will by displayed or hidden from the map accordingly. The "Out of Variance" sites are those that have violated any of the selected Variances (see below) in the most recent half-hour.

For example, if only Out of Variance sites are selected, you should only see the red out of variance sites. If only Operating Normally is selected, you should only see the blue normal sites.

Selecting Variances

Each Variance (Subrate Mismatch, High Int. Blocking, etc.) defines are particular formula that tracks whether a given Sector or Carrier is out of Variance from the norm. The norm is defined by a "threshold level" in the CROME report. For a full description of what each variance means, Click here.

The map will show sites in red if they currently out of variance for ANY of the variance selected. If no variances are selected, then all sites will appear in blue.

Rotating Variances

By default, the map shows all variances combined, i.e., if more than one variance is checked, sites matching any of the variances will be shown in red.

You can also choose to have the map automatically rotate between the selected variances. Configuring the GIS for rotating variances is shown below:

For example, if you choose "Rotate every 20 sec." then the map will rotate between each variance every 20 seconds. While the map is in "rotate" mode, the current Variance is displayed in blue on the control panel:

and both the title bar (and the "variance list" via the "active" tag) are updated to show which variance is currently displayed, as well as the number of seconds left before it switches to the next variance:

One typical use of the rotate feature is to make a network operations center (or NOC) big screen display. A NOC display can be created in a matter of seconds.

A screen sequance like the following might be displayed

20 seconds of "High Int Blocking" ...

20 seconds of "High Int Drop Rate"

20 seconds of "High Dispatch Queuing"

Even in rotation mode the NOC user can still hook the out of variance site to get feed back with the mouse. This is shown for the next variance 20 seconds of "High Dispatch Queuing".

However, since the "CROME Site Mapping and Variance Reporting" can feed 100s of Applet displays, an engineer at the NOC can simply analyze any problems on a small personal PC display without affecting a NOC big-screen display.

Followed by all other enabled variances in a rotation pattern.

It is important remember that every market or wireless operator has his own unique reporting needs (i.e., variance reports and thresholds levels). Adding a new real-time variance to the "CROME Site Mapping and Variance Reporting" is as simple as making a new CROME report (see Adding New Variances). This display is not a set of canned variances, rather it is an engine to display any variance that is critical to proactively manage local market or even national network infrastructures.

Sectors/Carriers out of Variance

When you click on a site on the map, the list on the bottom-right portion of the screen will fill-in with the sectors and carriers that are out of variance for this site, if any.

Each row in the list shows:

If you double-click on an item in the list, a new WWW browser page will pop-up, showing the details on this variance. It will show the values for each time it was out of variance in the last 48 half-hour periods (Note this is the exact same page you get from the standard CROME Variance web-page display):

NOTE: the detail page will always appear in the SAME browser window. Meaning, the first time you click on an item, a new web page will appear. The next time you click on an item, that same web page window will change to show the item selected. BE CAREFUL if you "minimize" the browser page that is showing the detail page, because if you click on a new item in the list, the "minimized" browser page will change to show the new detail page, but you may not notice because the page is minimized. (Alas, there is no way to automatically pop it back up and un-minimized it...)

Adding New Variances

The "CROME Site Mapping and Variance Reporting" is extremely configurable and flexible to add a new Variance a system administrator can either create a new CROME report or copy and existing CROME report and save it in the real-time "threshold" folder .

The seamless integration with the CROME Full "Ad-Hoc" reporting tool provides the addition for non-programmers to add new variance reports and/or modify existing variance reports.

Once the report exists in the real-time "threshold" folder the new variance is automatically reported on. Please refer to the "CROME Users Guide" for information on report creation.

Thus in seconds a new out of variance report can be defined or an existing report can be altered and once saved in the "threshold" folder (above) the results will automatically start showing up all of the following contexts:

In addition the data will be available to other TBD subsystems in a generic context via a common MCB feed and a well defined, easily parsed, canonical data structure.


The "CROME Site Mapping and Variance Reporting" can display views from both very local viewpoints such as a zip code or county to other larger areas such as a state or nation.

Above is an example of a national production demo of two CROME servers, one running a portion of the Western Region of a mjor US wireless carrier and the other running a portion of the Eastern region of the same carrier (due to space constraints only the west cost is shown to see the whole nation click here).


The "CROME Site Mapping and Variance Reporting" is built from a very generic foundation. For example, the same engine can be used to display Airplanes and/or arbitrary shapes in real-time.

Below is another telcommunications use which shows the analysis of drive test data with interactive mouse over capability to show location, frequency, rssi, db level, and SQE. This Applet uses the same CORE display as the "CROME Site Mapping and Variance Reporting" system.

Below are two pictures of a non-telecomunications example which tracks flights in real-time showing speed, direction, and altitude and squawk code. This example is from a system in place at San Francisco International Airport.

The above images show another use of this Quantum product displaying live data updated every second - once again using the same CORE mapping engine developed by Quantum for its GIS based applications.

It should be apparent that if the product is flexible and extensible enough to display real-time flight data and flight contrails - it can be easily handel and display any type of geometric objects. For example to data Quantum has integrated items including but not limited to:

Due to its unparalleled flexible design, Quantum customers typical use the "CROME Site Mapping and Variance Reporting" as a key large screen display component in both regional and national network operations centers.

Many Quantum customers, absolutely base there entire operations on the versatility of this Quantum technology to proactively manage their wireless and wireline operations. Since Qmap can both display real-time information to big screen displays in Network Operations Centers, or NOCs, and simultaneously display results to hundreds of users at their respective PCs and workstations - Qmap is a vital tool for finding and solving issues before they impact customers. In addition Quantum clients can add countless custom real-time formulas to be analyzed by this system for immediate feedback and tracking of both traditional and one time issue.
