The Steps Involved In Creating
a Predictive RF CAD Model and
Performing Coverage Simulation

From your floorplan to a complete, accurate Wi-Fi design without a costly and time-consuming on-site 802.11 Wi-Fi site survey

Connect802 licenses the same advanced RF modeling and simulation software that's been used for many years by cell phone companies to position antenna towers on the hillside and to design in-building cellular repeater systems. This software allows both outdoor and indoor simultion for RF design not only in the 800 MHz cellular bands but for 2.4 GHz (802.11b/g), 5.8 GHz (802.11a), WiMAX (802.16), WMTS (600 MHz) and other frequency bands.

Connect802 licenses multiple copies the Wireless Valley LANPlanner along with Wireless Valley Enterprise Planner RF CAD modeling and simulation software. Wireless Valley was founded in 1995 by Dr. Ted Rappaport, a world leader in RF design and management who holds numerous related engineering patents. The Wireless Valley software stands alone as the only 3-dimensional RF CAD modeling and simulation system of its kind. Motorola Inc. acquired Wireless Valley and is now supported through the Motorola RF Design and Management software team. Although the name "Wireless Valley" has officially been dropped from Motorola marketing, many long-time experts in the industry still tend to refer to it as "Wireless Valley predictive RF CAD modeling software."

Below you will find screen images and accompanying Flash movie clips showing the steps in creating an RF predictive model. You send your floor plan or outdoor map to Connect802 and our RF engineering team does the rest. Here's how it works:

  • A Connect802 RF design engineer formats your floorplans to create an accurate, 3-dimensional model of your space.
  • Antenna installation locations are then optimized through real-time signal coverage simulation.
  • Various types of coverage predictions are performed to assure that the system will operate within the required manufacturer's specifications and with proper support for the user community.

The modeling system knows the exact RF characteristics of the building's construction materials which is how the predictive designs can be highly accurate.

Each individual interior feature is examined and then assigned to an RF category. The level of detail to which this is done allows the predictions to show weak "shadow" zones, channel interference and other intricate RF behavior.

The transmitter and receiver characteristics of a new, virtual access point are defined in significant detail. The predictive modeling system doesn't assume that all access points work the same way.

Different sites deploy different applications to user communities with different needs and expcetations. Here, the design engineer fine-tunes the predictions to best match the projects real-world requirements.

As access points are positioned in the drawing the design engineer watches a real-time simulation of the ebb-and-flow of RF signal in the building. In this way an optimal location is determined for each transmitting antenna.

"Contour Coverage Prediction" allows an immediate, visual assessment of where an access point will provide coverage and how adjacent access points will overlap

"Grid Coverage Prediction" allows a detailed analysis of various key RF coverage parameters to both confirm that the design will meet specifications and to call out areas of concern that should be explored during an on-site RF spectrum analysis survey.

Predictive models are rotated in space to allow the design engineer the chance to carefully explore coverage from all angles. This helps avoid weak areas and dead spots in 3-dimensional space.

"3-D Contour Coverage Prediction" allows an assessment of how a transmitter will spill out of a building into adjacent parking lots or neighboring buildings.

This short video shows how designs were created for a warehouse, a retail store, and an outdoor truck yard. You'll get a good overview of how you can benefit from a Connect EZ Predictive RF CAD Design.
