Received signal strength is shown in large text in the center of the control, and as a green indicator in the top dial. The blue shaded bar and text immediately below the dial represent target signal strength based on distance and other information exchanged between radios. The objective is to align the green indicator with the blue bar as a guideline during antenna aiming.
The resulting half-duplex PHY rates shown at the bottom of the Signal Meter control are correlated with the MCS, and represent raw data across the link without protocol overhead. The Max Throughput values include TDMA window size and MAC layer efficiency.
The following settings and values that affect link health are listed for reference:
Click the Spectrum Analyzer button to access the Spectrum Analyzer, which can also be found on the Channel & Power page. This will not disturb the link.
When a link is not associated, the signal strength and PHY rates are replaced by an indicator of "Disconnected".
Once associated, click the Aiming Mode button on the Dashboard to open a new window that refreshes once per second for a 5-minute period. The Aim Heading indicates the direction in which the front of the device should be pointed based exchange of coordinates. The green arrow and blue shaded region on the dial indicator represent current and target signal levels, respectively. Note that the dial indicator does not represent azimuth. Azimuth may need to be adjusted in either direction to meet the target.
The MIMO Status panel contains two tables: Chains and Streams. Chains represent the physical medium (RF Tx/Rx values), while Streams represent data. Chains and Streams are not necessarily correlated one to one because the Rate Adaptation algorithm may periodically increase or decrease the number of data spatial streams sent over the physical medium when reacting to interference.
The Chains table describes each chain's power, noise, Carrier-to-Interference and Noise Ratio (CINR) , frequency and polarization.
The Streams table describes each spatial stream's MCS index, PHY rates and Rx Signal-to-Noise Ratio (SNR).
Each table can be selected by clicking on the navigation circles at the bottom of the panel.
The QoS Statistics panel contains the Queue table. The Queue table helps the user determine how many packets and bytes have been transmitted and received over the wireless link. Queues are buffers in devices that hold data to be processed. Queues provide bandwidth reservation and prioritization of traffic as it enters or leaves a network device. If the queues are not emptied, they overflow and drop traffic.
The Per Queue Performance table describes each queue and the bits and packets transmitted over the wireless link.
The Per Queue Details table describes Queue, Tx Latency, Tx Jitter, and Packet Loss Rate.
The Per Queue Performance table contains 5 values: Queue, Tx PPS, Tx bits/s, Rx PPS, and Rx bits/s.
The Per Queue Details table contains the Queue, Tx Latency, Tx Jitter, and Packet Loss Rate.
The Device Details panel shows two summary tables for the local and remote device configurations and their status.
Click on the navigation circles at the bottom of the panel to toggle between the two tables.
The table shows the following for both Local and Remote devices:
IP Throughput and Packet Error Rate (PER) are charted over 60 seconds or 15 minutes. The newest data shows up on the right and scrolls to the left over time. You can toggle between the charts by clicking on the navigation circles at the bottom of the panel. If enabled, click on the cloud icon to view historical data within the Manage application.
The IP Throughput graph plots three lines representing transmit, receive, and aggregate (summed) throughputs at the datagram (or packet) layer excluding any protocol or encapsulation overhead. The results here may differ from those measured using speed test tools, due to protocol overhead and encapsulation.
The Packet Error Rate (PER) is the number of packets with errors divided by the total number of packets sent. Ideally, this value should be below 2%, while higher values indicate the presence of interference. Tx PER is an indication that the local radio did not receive an ACK from the remote radio, so is forced to retransmit the same information again.
The Spectrum Analyzer actively scans the spectrum in the background to report on interference sources that may impact link performance.
Click the Local, Remote, or Combined buttons to each radio's spectrum individually or simultaneously. Note that the remote side data may be as much as 5 minutes behind the local radio. Click on the half circle icon in the upper right to toggle the graph's background color between black and white.
Channels in use have higher Power Spectral Density (PSD) on the vertical axis, and are shaded in different colors to represent how often the signals are likely to be on the same frequency at the same amplitude.
The legend to the right of the graph explains the color code for the Cumulative Distribution Function (CDF). The color red suggests the highest probability (1 = 100%), while purple represents the lowest probability (0 = 0%).
Cross hairs appear on the graph beneath the mouse pointer along with an information box containing the frequency (channel), PSD, and CDF values.
There are three types of markings, or bars, immediately beneath the graph’s horizontal axis that indicate frequency ranges that are restricted, manually excluded, or in active use by this link. Note that traffic from the Active Channel is excluded from the display so that noise can be detected.
The Backup and Restore Configuration panel contains controls for managing configuration settings files.
Reboot the device or reset it to its original factory settings.
Once the remote radio enters the Upgrade phase, it is generally safe to begin the Upload phase to the local radio. Alternately, the Mimosa Manage application offers a parallel upgrade feature which sends the firmware image to both radios, and once both radios receive and verify the image, they upgrade at the same time and reboot in an order that you specify.
Three types of tests are available within the Diagnostics section: Ping, Bandwidth, and Traceroute.
A low level ICMP test which indicates whether the target host is reachable from the local device.
A manual test to assess maximum throughput when minimal or no traffic is present. This test sends 1500-byte packets using a proprietary UDP-like protocol. The results are shown in the corresponding graph on this page. This is because the test is conducted by transmitting packets at a low layer between the two radios. Navigating away from this page will stop the test.
A network utility used to display the path and transit delay between the local device and a given destination across an IP network.
A network utility used to check connectivity to the Mimosa Cloud.

In the United States, if either the AP or STA are within a 60 km radius of a Terminal Doppler Weather Radar (TDWR) location, one or more 30 MHz restrictions are automatically created to avoid the TDWR operating frequencies.
The TDMA Configuration panel contains controls for configuring and fine tuning TDMA performance. One side of the radio link must be set as an Access point, and the other set as a Station. The Station inherits the other settings from the AP, so the other fields are grayed out and not accessible when Station is selected.
Enter the latitude and longitude of the local radio in signed decimal degrees with four digits after the decimal point (e.g. ##.####). These values are used to display the radios on a map within Mimosa cloud applications.
Enter the latitude and longitude of the remote radio in signed decimal degrees with four digits after the decimal point (e.g. ##.####). These values are used to display the radios on a map within Mimosa cloud applications.
The calculated distance between radios based on the local and remote coordinates. This value is used to calculate propagation delay.
The Local Satellite Signals panel contains a chart showing both GPS and GLONASS satellites in blue and green, respectively, from which the radio can obtain position and timing data used for synchronization. Each numbered column represents a unique satellite with the columns’ amplitude representing the signal to noise ratio of the satellite’s signal at the radio’s receiver. The number of satellites the radio detects and the SNR of each both contribute to clock accuracy.
The Satellite Information panel contains values that represent and contribute to clock accuracy. Good GPS signal strength is required for maximum performance, as the GPS is used to synchronize timing between devices.
Status table showing location, altitude, and heading for both the local and remote devices, as well as the link distance between them.
The Survey Results status table summarizes the results of a site survey of SSIDs broadcast by Mimosa and non-Mimosa Access Points.
The table provides the following data per device found:
Note: The Site Survey will temporarily interrupt your link. Once started, this process cannot be stopped until complete.
Use the Start Survey button to place the radio into the scan mode to search for 802.11-compatible access points.
The Last Updated field indicates (down to the second) when the last Site Survey was requested.
It is important to note that running a site survey will temporarily take down your link. Once activated, this process cannot be stopped until complete. Please plan accordingly.
The device name and description are local identifiers for administrative purposes, and are not used as part of the wireless link.
The Time panel shows the current date and time in Coordinated Universal Time (UTC). The Install Date input box can be used for administrative purposes, but it is optional and has no other affect.
Enter the new password in both the New Password and Verify New Password input boxes to validate that they were typed correctly. To finalize the change, enter the existing password and then save. The default password should be changed during device configuration to protect your network.
The Password rules are as follows for choosing a password:

Note that this feature need only be activated when using a third-party monitoring system that supports REST calls. REST services require that HTTPS is enabled.
The 2.4 GHz wireless interface allows local browser-based configuration with any Wi-Fi capable device. This is a low power interface that performs best if accessed within 60 meters (~200 feet) of the radio. It is completely separate from the link and has no performance impact on throughput if activated.
Note:
If you turn off the 2.4 GHz management radio, you can still access the device through the wired LAN interface, or in-band through the primary wireless link.
The 2.4 GHz Security panel contains controls for managing access to the local wireless management network.
Enable the SNMP service to allow SNMP requests and enable push notifications to a remote server.
