3Com 3CRWXR10095A, 3CRWX120695A WXR100 manual Coverage Display Options in Explore Window

Using the Explore Window 411

The jagged appearance of the coverage area is normal and is caused by the RF obstacles around the radio. The RF obstacle information in the floor plan enables 3WXM to more accurately portray RF information for the network, including a radio’s coverage. If the coverage area for a radio is displayed as a sphere, then the floor plan does not have any RF obstacles around the radio. (To add RF obstacles to a floor plan, see “Specifying the RF Characteristics of a Floor” on page 94.)

You can control how the coverage is shown by selecting an option from the Show RF Coverage Using box in the window’s toolbar. Table 35 lists the options.

Description

Coverage is shown based on the MAP radio’s baseline association rate. The baseline association rate is the typical data rate the radio is expected to support for client associations.

The baseline association rate is specified during planning, on a coverage area basis.

Coverage is shown in colored bands that represent each of the data transmit rates supported by the radio. These rates are standard for each radio type.

Coverage is shown based on the received signal strength indication (RSSI) of the radio’s signal heard by other radios.

Average signal-to-noise ratio (SNR) for clients in each data rate.

Average number of clients at each data rate.

Average SNR for clients in each RSSI band.

Average number of clients in each RSSI band.

For all display options except the baseline association rate, a legend is displayed at the bottom of the window to indicate the values represented by each color.
