Monitoring the RF Neighborhood

View a radio’s neighbors with this list. There are two options for viewing the neighboring devices of a radio. You can either view the results of a selected radio’s scan for neighbors, or you can view the result when all other radios in the network found the selected radio. This topic describes both options.

This topic describes:

Procedure for Viewing a Radio’s Neighbors

You can monitor the access points operating in the neighborhood of a specified radio.


To view a radio’s neighbors:

  1. Select Monitor Mode in the Network Director banner.
  2. Select any View from the View pane.
  3. Expand the list in the View pane, and then select a radio.

    The RF monitor tab becomes available when an access point or a radio is selected. The neighbors data is available only for radios.

  4. Click the Monitor mode RF tab. The four basic radio monitors are displayed.
  5. Click Show Neighbors in the Tasks pane on the right.

    The current neighbors for the selected radio are displayed with a list of transmitters heard by this radio.

  6. Select either of the options: Transmitters heard by this radio or Listeners that heard this radio. Table 325 describes these options.

    Table 325: Neighbor Tracking Options



    Transmitters heard by this radio

    Select to view the selected radio’s scan results for other transmitters in the neighborhood of the radio.

    Listeners that heard this radio

    Select to view a list of other radios on the network that can hear the selected radio.

  7. Click Help (?) for information about the RF Neighborhood list or refer to the RF Neighborhood List.

RF Neighborhood List

The RF Neighborhood list includes either the neighbors located by the radio you indicated in the View pane or the neighbors that can hear the radio you indicated in the View pane. Determine which way the data will be displayed by selecting either Transmitters heard by this radio or Listeners who heard this radio. Either way, the neighbor details reported are described in Table 326.

Table 326: Data For Neighbors Located by the Radio Scan




Wireless access point radio in close enough proximity to be detected by another access point radio.


Identifier for an access point.


Number of the channel used by the neighbor radio—in the 2.4-GHz band, this is usually 1,6, an 11 in the US. In the rest of the world, channels 1, 5, 9, and 13 are used most often. The 5-GHz band has 24 usable channels, (36,1) (40,-1) (44,1) (48,-1) (52, 1) (56,-1) (60,1) (64,-1) (100,1) (104,-1) (108,1) (112,-1) (116,1) (120,-1) (124,1) (128,-1) (132,1) (136,1) (149,1) (153,-1) (157,1) (161,-1). The +1 and -1 indicated for some channels above indicate channel bonding, where a channel bonds with the one above or below it.


Received signal strength indicator (RSSI) is the relative received strength of a signal in a wireless environment. RSSI is basically an indication of the power level being received by the antenna—therefore, the higher the RSSI number, the stronger the signal. (Because the numbers are negative, -50 represents a stronger signal than -88.)

You can perform the following actions on this list:

RF neighbor information is available only for radios.
