Overview

The VisualRF module is an add-on to the Dell PowerConnect W AirWave Wireless Management Suite

(AWMS) that provides a real-time picture of the actual radio environment of your wireless network and

the ability to plan the wireless coverage of new sites.

To understand what is happening on your wireless network, you need to know where your users and

devices are located – and you need to monitor the RF environment in those areas. The VisualRF

module puts this information at your fingertips through integrated mapping and location data.

VisualRF uses sophisticated RF fingerprinting to accurately display coverage patterns and calculate the

location of every wireless device in range. Moreover, VisualRF does not require dedicated RF sensors or

a costly additional location appliance – all the necessary information is gathered from your existing

wireless access points and controllers.

Features

•Floor plan upload wizard enables direct importation of JPEG, GIF, PNG, and CAD files for floor

plans.

•Batch upload wizard enables batch uploads of multiple CAD files with corresponding walls, and

access points.

•Accurate calculation of the location of all client devices (laptops, RFID Tags, PDAs, Phones) using

RF data from your existing APs and controllers. Location accuracy increases with higher density,

providing more data points to triangulate the location of each device. Further improvements in

accuracy can be achieved with site surveys.

•3D navigation allows your Help Desk to view floor plans simply by clicking on the appropriate

campus, building, or floor.

•Tree view allows customer to navigate to a specific campus, building, or floor via a tree navigation.

•Heatmaps depict the strength of RF coverage in each location

•Color-coded channel maps help you reduce interference and quickly identify or detect potential

coverage holes.

•Data rate view which depicts the highest possible data rate at every location on a floor plan.

•Integrates with the Dell PowerConnect W AirWave Wireless Management Suite for onscreen

display of alerts and error conditions (i.e., an AP icon will display in red when a critical alert is active

or when usage conditions exceed pre-defined thresholds)

•Location playback viewer which allows visual tracking of up to 24 hours of location history.

•Dynamically recalculates path loss and device locations based on real-time data from your wireless

LAN, for increased location accuracy.

•Calibrates RF data from multiple vendors’ APs (and across different product lines from the same

vendor) for accurate display even in multi-vendor and multi-architecture environments.

•Full planning capabilities based on data rate or signal requirements.

•Google Earth integration for depiction of outdoor coverage and device location.

Useful Terms

•VisualRF – The service within AMP that calculates location, calculates path loss, and provides floor

plan editing capabilities.

4 Visual RF an d Visual RF Plan | User Guide

•VisualRF Plan – Makes the planning portions of VisualRF available in an offline software package

that does not require a server.

•QuickView – Flash front-end for VisualRF which displays information generated by the backend

service.

•mW – 1/1000 of a Watt. It is a linear measurement (always positive) generally used to represent

transmission.

•dB (Decibels) – difference/ratio between two signal levels.

•dBm – dB as compared to 1 mW. It is a logarithmic measurement (integer) which is typically used

in place of mW to represent receive-power level. AMP normalizes all signals to dBm, so it easy to

evaluate performance between various vendors

•RSSI (Received Signal Strength Indicator) - IEEE defines RSSI is a mechanism by which RF

energy is to be measured by the circuitry on a wireless NIC (0-255). RSSI is not standard across

vendors. Each vendor determines their own RSSI scale/values.

•AP-to-AP Signal (Neighbor) – Some APs/Controllers have the ability to report the signal strength

of APs that they hear. AMP utilizes these signal strength readings to dynamically attenuate floors

plans thus making client locations and heat maps more accurate.

•Unassociated Client Information – Some APs/Controllers have the ability to report the signal

strength clients they hear, but are not associated with a radio on the AP. AMP utilizes these signal

strength readings to more accurately place clients.

•Client Surveys – Client surveys are facilitated completely within VisualRF and utilize access points

to understand which clients they hear and at what signal strength.

•Rogue Surveys – Rogue surveys are facilitated by AMC and VisualRF and utilize the client’s radio

to understand which access points they hear and what signal strength.

AWMS is the only WLAN management application that understands unique RF characteristics for

every enterprise WLAN manufacturer. This includes receive sensitivity at all data rates, antenna

characteristics, and supported transmit power levels for every architecture and individual model. AMP

normalizes signal metrics which might come as RSSI or SNR into dBm enabling customers to visualize

and compare different vendors, models, and architectures.

Basic QuickView Navigation

QuickView is designed to be very intuitive with easy to use pull down menus. The RF pull down menus

are split into two major categories, display toggles and editing tools.

Display Toggles

dBm of signal and assuming a client transmit power of 100 mW.

•Sensor Coverage – provides the farthest area which a sensor can hear.
