Mimosa Backhaul Overview

Accessing the Graphical User Interface

Accessing the graphical user interface (GUI) requires that the radio first be connected to power. The Power over

Ethernet (PoE) connection process describes the steps to do this. Note that the GUI will be available approximately

one minute after applying power.

The GUI can be accessed in three ways to facilitate set-up and management.

Locally through the built-in 2.4 GHz wireless management network (B5/B5c and B11 Only)1.

Through the local Ethernet interface (LAN), or the fiber (SFP) if applicable2.

Remotely through the Point to Point wireless link3.

Via 2.4 GHz Management Network

On any device with 2.4 GHz 802.11n capability, go to the wireless network listing and connect to the Local Network

Management wireless network (SSID): "mimosaMXXX". The default passphrase for the 2.4 GHz connection is

"mimosanetworks". Once connected, type 192.168.25.1 into your browser. Please note that both the Local Network

Management SSID and passphrase are configurable by the user, so their values could be different from the default

values.

Via Ethernet interface or in-band over the Point to Point link

By default, the device IP address is 192.168.1.20 and can be accessed via the Ethernet port using this IP address in

any standard Web browser. To access the device via a locally connected computer initially (on the same LAN or

directly to the Ethernet port), the computer’s IP address must be on the same subnet as the above address. Once

you have modified the IP address (static or is DHCP) of the device for remote management purposes (in-band over

wireless or over the Ethernet interface), the new specified IP address must be used to access the device. This is

important to do in order to avoid IP address conflicts with other devices on the network. Current IP addresses of

different Mimosa devices on the network can be identified using terminal-based discovery. It is highly recommended

to change the default password to a unique and secured password.

Mimosa Backhaul and B24 Help Content

Mimosa Backhaul Overview

Logging In

After connecting via one of the three access methods, the GUI will prompt you to log-in with a password. The

default password is "mimosa", and should be changed immediately after login to protect your network since it gives

the user read / write privileges. The password can be changed within the Preferences > General > Set Password

panel of the GUI.

User Interface Overview

When you first log in, you’ll notice that there is a title bar with the device name shown in the top-right corner, a

navigation pane on the left, and a large content pane on the right. The default page shown in the content pane is

the Dashboard, which shows a summary of overall performance at a glance, and highlights both radio and link

parameters that affect link health.

On the left navigation pane, there are four prominent sections: Overview, Wireless, Preferences, and Diagnostics.

Each of these sections contains one or more links to pages containing task-related data, controls, and tools used to

administer the radio…and you can return the Dashboard at any time by clicking on the Dashboard link in the

Overview section.

The pin in the top corner of the left navigation pane allows you to "pin" open the navigation menu for easier access.

Reading the Signal Meter

Connected Link

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:

Reading the Performance Charts

IP Throughput and Packet Error Rate (PER) are charted over 60 seconds in 5-second intervals. 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. Note that internal Bandwidth

test results are excluded.

The Packet Error Rate (PER) is the number of packets with errors divided by the total number of packets sent within

a 5-second period. 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. Rx PER is a value sent from the remote radio to the local radio in management frames.

Mimosa Backhaul and B24 Help Content

Mimosa Backhaul Dashboard

Note: PER will be higher upon initial association, and will usually settle within 30-60 seconds. This is

because association requires that the radios “listen” more carefully for their link partner until they are

linked, and this listening period is subject to more interference until Automatic Gain Control (AGC) and

Rate Adaptation (RA) adjust parameters to accommodate the conditions. PER values are exchanged

between radios asynchronously, so the values may not match exactly when referencing both radios at the

same time.

Reading MIMO Status Tables

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 streams sent over the physical

medium when reacting to interference.

The Chains table describes each chain's power, noise, SNR, frequency and polarization.

The Streams table describes each stream's MCS index, PHY rates and Rx Error Vector Magnitude (EVM).

Each table can be selected by clicking on the navigation circles at the bottom of the panel.

Chains

The Chains table contains 6 values: Tx Power, Rx Power, Rx Noise, SNR, Center Frequency and Polarization. Each

channel is assigned two chains (horizontal and vertical). If two channels are selected, Channel 1 uses Chains 1 & 2,

while Channel 2 uses Chains 3 & 4.

Tx Power is the amount of power applied to each of the MIMO chains.

Tx Power can be shared evenly (preferred), or unevenly (if necessary), between channels. The Tx power

per channel is divided evenly per chain. Example: 4 dBm Tx power on Channel 1 results in 1 dBm each on

Chains 1 & 2.

Rx Power is the incoming signal level from the remote radio. Larger values are better (e.g. -50 dBm is better than -

60 dBm).

Rx Noise is a combination of the thermal noise floor plus interference detected by the local radio. Smaller values are

better (e.g. -90 dBm is better than -80 dBm). Noise sources can be either in close proximity to the local radio, or

they can be remote transmitters pointed back at the local radio.

Mimosa Backhaul and B24 Help Content

Mimosa Backhaul Dashboard

The signal-to-noise ratio (SNR) is the difference between the Rx Power and Rx Noise, and is a measure of how well

the local receiver can detect signals from the remote transmitter and clearly discern them from noise. Higher

values are better (e.g. 30 dB is better than 10 dB).

If two channels are selected, you may observe that SNR is much lower on one channel than the other. This could be

because the Tx Power is set lower on the remote transmitter, or because of higher interference levels on the

channel. To resolve this, increase Tx Power or change the channel that has lower SNR.

Chains 1 & 3 have horizontal polarization, and Chains 2 & 4 have vertical polarization. Chains with the same

polarization are combined internal to the radio before exiting to the antenna connectors.

Streams

The Streams table contains the Tx MCS index, Tx PHY rate, Rx MCS index, Rx PHY rate, and the Rx EVM for each

stream.

The Tx MCS is an indicator of how well the remote radio can receive data from the local transmitter. The Rx MCS

indicates how well the local radio is receiving data from the remote transmitter.

The Modulation Coding Scheme (MCS) represents how much data can be sent at a time, so directly affects

potential throughput represented by the PHY rate. The higher the MCS index (ranging from 0-9), the more

data that can be sent per transmission. A disadvantages of higher MCS indices is that they require higher

SNR since they are more vulnerable to noise.

The Error Vector Magnitude (EVM) indicates the difference between the actual and expected amplitude and phase of

an incoming signal. Smaller values are better (e.g. -30 dB is better than -10 dB).

Rate Adaptation dynamically adjusts both the MCS and the number of streams depending on RF conditions. Poor RF

conditions (i.e. interference) causes PER to increase. PER and MCS are inversely correlated meaning that as PER

Mimosa Backhaul and B24 Help Content

Mimosa Backhaul Dashboard

increases, MCS decreases and vice versa.

Single channel mode usually uses 2 streams, but may drop to one stream if RF conditions are poor. Dual channel

mode uses up to 4 streams. You may also see the number of streams change periodically because of tests that

Rate Adaptation performs to optimize performance. This is expected and normal.

Reading the Spectrum Analyzer

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.

Note: Buttons on the upper right of the graph show the spectrum for the local radio, the remote radio or a

combined view.

Fiber (SFP) Port - When Fiber (SFP) is ON, SFP is used for data and management. Fiber (SFP) Fail Safe option is

●

only available when Fiber (SFP) is ON. When Fiber (SFP) is OFF, by default, Ethernet (RJ45) is used for both data

and management traffic.

Fiber (SFP) Fail Safe - When Fiber (SFP) link goes down, data and management traffic will fail-over to Ethernet

●

(RJ45) and traffic will pass through Ethernet (RJ45) if available. If Fiber (SFP) Fail Safe is OFF, and if Fiber (SFP)

goes down, all traffic will be blocked.

Ethernet (RJ45) Speed - This drop-down allows the user to select one of the following options: Auto, 10, 100,

●

1000BaseT (at full or half duplex). Auto setting is recommended.

Mimosa Backhaul 2.4 GHz Console

Enabling the 2.4 GHz Network

Product Applicability: B5/B5c, B11

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.

Network Mode - Choose to automatically or manually enable or disable the 2.4 GHz management network. The

●

automatic mode turns the 2.4 GHz management network on for a limited time (defined in Console Timeout)

after boot and then turns it off if there is no activity. If a user associates with the radio within the timeout

period, they will not be disconnected.

Console Timeout - Set the number of minutes (1-60) of inactivity that will be allowed on the 2.4 GHz interface

●

before turning it off in Auto mode.

SSID (Local Management) - Set the SSID name for the 2.4 GHz local management interface.

●

Channel - Select the channel on which the 2.4 GHz wireless network will operate.

●

Recovery SSID - This is an non-editable recovery SSID that allows the device to be reset to factory defaults. This

●

is available for 5 minutes after device boot. Disabling the 2.4 GHz management network will not impact

availability of this option. The serial number of the device must be known in order to perform the factory reset.

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 5 GHz wireless link. During the B5/B5c device reset process, the 2.4 GHz wireless interface is

briefly re-enabled, and then disabled after a timeout.

Mimosa Backhaul Firmware & Reset

Performing a Firmware Update

The Firmware Update panel displays the current firmware version and date, and allows the user to upload a new

firmware image. The latest firmware image may be downloaded from help.mimosa.co. Alternately, firmware can be

pushed to the device automatically through the Manage application at manage.mimosa.co.

Installed Version - The currently installed firmware version.

●

Build Date - The date that the installed firmware was created.

●

Image File - Update to the latest firmware. Click the Choose File button to select a file for upload the file.

●

When performing a Firmware upgrade, it is advisable to reboot and then upgrade the remote side of the

link before the local side. If there is a problem during the upgrade you will still have access to one of the

radios within the link and can manage the link details.

The firmware update process occurs in four phases:

Upload - Selecting a firmware image and uploading to the radio1.

Verification - Ensuring that the firmware image is complete and without errors2.

Upgrade - Writing the new firmware image to flash memory3.

Reboot - Restarting with the new firmware image (120 seconds)4.

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.
