RF Health and Utilization

The RF Health and Utilization dashboard provides long-term radio frequency (RF) health and utilization pattern for your network. With the information, you can analyze channel utilization trends for different radio bands across various sites, floors, and access points (APs), ensuring optimal performance and capacity planning.

Watch Juniper Mist Premium Analytics: RF Health Utilization for more details.

Features and Benefits

  • Provides insights into channel utilization breakdown, identifying traffic, background noise, and interface sources, empowering you to optimize network resources.

  • Provides information to detect the worst DFS channels affected by radars, understand radar patterns, and proactively mitigate interference maintaining a reliable wireless network.

Before You Begin

Access RF Health and Utilization Dashboard

To access the RF Health and Utilization dashboard:

  1. In Juniper Mist portal, click Analytics > Premium Analytics .
  2. On the Premium Analytics page, click RF Health and Utilization.
    Figure 1: AP Insights AP Insights
    The RF Health and Utilization dashboard appears.
  3. Use the filter options available at the top of the dashboard to view specific information.

    • Click Report Period and select one of the defined reporting periods. Alternatively, select a range of days from the calendar to customize the reporting period. By default, the dashboard shows data for the last 7 days.

    • Filter by Site Name, Floor Name, and Access Points.

    • From the dashboard actions on the top-right corner of the dashboard, select Reset filter to reset the filters.

RF Health and Utilization Tiles

SLE - Coverage and Capacity

The Traffic by AP tile shows charts for SLE metrics—coverage and capacity—for the selected duration.

Figure 2: Traffic by AP Traffic by AP
In the graph, one line represents the coverage of SLE, while the other denotes the capacity of SLE. Place the cursor on the line graphs to see the SLE percentage at any given time.

The Juniper Mist portal displays each SLE metric as a percentage that represents the success rate of the metric.

  • Coverage—Identifies the number of user minutes that a client’s received signal strength indicator (RSSI), as measured by the access point, are within the configured threshold.
  • Capacity—Tracks the user minutes that a client experiences low capacity because of interference, number of attached clients, and usage by the attached clients.

You can hide one of these graphs by clicking the name in the legend below the chart.

SLE by Site(s)

The tile shows charts lists sites with SLE metrics - coverage and capacity for the selected duration.

Figure 3: SLE by Site(s) SLE by Site(s)

The tile displays coverage and capacity SLE metrics for each site. Juniper Mist displays percentage that represents the success rate of the metric.

In the above sample, 100 percent of the devices in the Westford site and 90.7 percent of the devices in the Live-Demo site experience the expected level of network capacity.

According to the sample, 100 percent of the devices in the Westford site and 80.2 percent of the devices in the Live-Demo site experience the expected level of coverage.

Total Wired Traffic

The Clients by AP tile shows wired network traffic in the site for the selected period.

Figure 4: Total Wired Traffic Total Wired Traffic

Hover over the chart to view the volume of traffic at a given time.

Total RF Traffic

The Total RF Traffic tile shows RF-based traffic in the site for the selected period. The details include usage by the 2.4-GHz, 5-GHz, and 6-GHz bands.

Figure 5: Total RF Traffic Total RF Traffic

You can see three lines in the chart each representing 2.4-gigahertz (GHz), 5-GHz, and 6-GHz bands. Place the cursor on the chart to see the traffic volume for the selected band. You can hide one of these three graphs by clicking the name in the legend below the chart.

Busiest APs

The tile displays the most active APs in the network, ranked according to their traffic usage.

Figure 6: Client Stats Client Stats

You can view on the tile:

  • AP name—Name of the AP.
  • Site Name—Name of the site that an AP is associated with.
  • GBytes—Traffic volume on an AP.
  • Tx Gbytes (Gbps)— Received traffic volume.
  • Rx Gbytes (Gbps)—Transmitted traffic volume.

Total Retries

The tile displays the data transmission and reception retry attempts by a wireless device.

Figure 7: Total Retries Total Retries

Wireless retry refers to the instances when data frames must be retransmitted between a client and an AP due to an error. s On the Total Retries tile, you can view:

  • AP name—Name of the AP.
  • Site Name—Name of the site with which an AP is associated.
  • Local time—Timestamp of the data.
  • Total Packets—Volume of traffic flow through an AP.
  • Total Retried—Volume of retried-traffic flow through an AP.
  • Percent Retried—Percentage of retried-traffic through an AP.

Average Channel Utilization by Site(s)

The tile displays the percentage of channel utilization trends in the 2.4-GHz, 5-GHz, and 6-GHz radio channels grouped by sites.

Figure 8: Average Channel Utilization by Site(s) Average Channel Utilization by Site(s)

In the preceding sample, the Live-Demo site uses 0.17 percent of the 2.4-GHz channel, 23.47 percent of the 5-GHz channel, and 4.06 percent of 6-GHz channel.

Channel Utilization Breakup

The tile displays the percentage of channel utilization by APs and channel utilization breakup trends in the 2.4-GHz, 5-GHz, and 6-GHz radio bands.
Figure 9: Average Channel Utilization and Utilization Breakup Average Channel Utilization and Utilization Breakup

You can view:

  • Top APs - 2.4Ghz, 5Ghz, and 6Ghz Avg Channel Utilization—List of top APs sorted by the percentage of channel utilization in each band.
  • 2.4Ghz, 5Ghz, and 6Ghz Band Utilization Breakup—Band utilization trend by non-wireless client traffic, wireless client traffic, and background. Hover over the chart to view the exact percentage of channel utilization.

RRM Insights

The tile displays Radio Resource Management (RRM) events per site.

Figure 10: RRM Insights RRM Insights

RRM continuously optimizes wireless coverage and capacity across an entire site, for example to maintain SLEs. Channel and power level changes on a single AP are triggered when an RRM event occurs. The reasons for triggering an RRM event include scheduled RRM, co-channel interference, radar detection, and many more.

  • RRM Events per Site—Percentage of RRM event distribution per site.
  • RRM Events Top APs—List of APs ranked by the number of RRM events.

  • RRM Event Reasons—Numbers of RRM event reasons per site.
  • RRM Event Trend—RRM event trends classified by the reasons. Place your cursor on a point in a line graph to see the exact number of an RRM-event reason with the event time stamp. To hide information about a reason from the chart and see information only about the remaining reasons, click the reason name in the legend.
