Wi-fi connections are ubiquitous and have turn out to be part of our day by day lives. However planning after which sustaining a Wi-Fi community, optimized for in the present day’s radio protection and capability necessities, will not be a day by day and even yearly job for an in any other case seasoned community administrator.
Whereas wi-fi applied sciences are ubiquitous, they nonetheless work together with the bodily surroundings. Architecting the perfect protection for a selected surroundings depends upon many various elements like obstacles (partitions, doorways, home windows), constructing geometry and supplies in addition to the variety of customers and meant utilization. Trying throughout verticals demonstrates a variety in complexity that may be encountered inside totally different environments. For instance, protecting a average sized Enterprise Workplace area could possibly be so simple as appropriately inserting some APs with omni-directional antennas, whereas protecting a excessive ceiling warehouse means directional antennas to cowl the area and extra engineering to get it proper. The problem is that RF, except visualized one way or the other, is invisible. Seeing the RF in sufficient context to find out the right angles, energy, protection, and capability wants requires good instruments.
Our new answer
Cisco Wi-fi 3D Analyzer modifications the general planning and upkeep expertise for community operators. It offers a visible 3D immersive expertise that simplifies most of the points of the processes talked about above.

Cisco Wi-fi 3D Analyzer brings the wealth of wi-fi telemetry information already accessible in Cisco DNA Heart and combines this with the highly effective context that the interactive 3D mannequin can present. The analyzer not solely permits the consumer to see all this data in context, but additionally permits the highly effective evaluation engine to mix 1000’s of knowledge factors and supply actionable conclusions. The system minimizes the handbook tuning, requiring a web site go to, to optimize the community. The methods, utilizing over-the-air measurements, permits verification of correct operations or provides clear indications on what would require some tuning, not simply on Day 0, however for the life cycle of the deployment to Day n.
How does it work?
The Cisco Wi-fi 3D Analyzer offers each Life Cycle Administration and Planning inside an immersive 3D operational expertise.
Planning
Given a CAD or Ekahau Undertaking file, that incorporates information concerning partitions and supplies, the app generates a 3D mannequin of the surroundings and makes use of predictive modeling to show the RF protection from the ground to the ceiling. Enter for the mannequin depends on telemetry accessible to precisely describe the present energy, channels, and even antenna coordinates dynamically to render the surroundings. The highly effective evaluation engine seems to be on the thousands and thousands of interactions between the entry factors, shopper gadgets, sensor APs, and the described bodily surroundings throughout the 3D flooring space. The 3D Analyzer can dynamically establish and isolate for view any service stage points found.

Upkeep
Not like a standard static 2D warmth map, the Cisco Wi-fi 3D Analyzer additionally correlates actual time information from the community. That is attainable by means of the Cisco DNA Heart telemetry and the Catalyst stack structure, sensors, and assurance information. It permits correlation of the predictive outcomes with the precise measured floor reality within the 3D flooring map. This not solely offers visible assurance of the accuracy, however a dynamic technique to alert to dangerous modifications within the bodily world. The 3D surroundings is augmented with the entry factors’ runtime well being rating in addition to different essential information at a number of ranges throughout the “digital actuality”. See the well being scores under inside the coloured tear drops.
Determine 3 – Prediction and Measurement (level cloud view)
Additionally please word that accessible sensor measurements are additionally built-in into the general massive image of your community. Sensors are proven above within the circles labeled S.
The under chart illustrates the principle information flows driving the 3D Analyzer’s view of the bodily world. It’s plenty of correlation, and an unprecedented view of the community’s context.
The Cisco Catalyst community offers dwell information to Cisco DNA Heart, which is drawn on by Cisco Wi-fi 3D Analyzer. Utilizing the ground maps, precise stock HW fashions and present configurations, the app can generate the predictions and their correlation with the dwell information, offering a full 3D context wealthy visualization surroundings.
Key use circumstances
Listed below are a couple of use circumstances that Cisco believes brings new efficiencies and accuracy to your view of the community.
Visible insights
The Cisco Wi-fi 3D Analyzer correlates the expected information together with telemetry inputs, analyzes the outcomes, and offers insights into the networks conduct. Within the instance under, the system detected that 67% of the ground’s RSSI protection falls under the user-configured KPI (Key Efficiency Indicator) of -70dBm. With a single mouse click on on the Perception, the surroundings is configured immediately to spotlight the precise location of deficiency, immediately offering a transparent and actionable view.
