Mimosa Client Help Content Mimosa Clients Performance SNR Required for Each MCS The table below shows the SNR required for each MCS index as well as the modulation, coding and data rate per stream based on channel width in MHz. Note that each channel uses up to two streams.
Mimosa Client Help Content Mimosa Clients Performance Error Vector Magnitude (EVM) The error vector magnitude or EVM describes how well the receiver can detect symbols (data) within a constellation of symbols on the I-Q plane for a particular modulation. It is the difference in RMS power between the point where a symbol is received and where the symbol should be.
Quality of Service (QoS) Support Mimosa radios support four different L2/L3 QoS queues for traffic prioritization. Typically, an upstream router sets values for CoS (L2), or DSCP/TOS (L3) for specific traffic on the post-routing chain. After packets leave the router, they enter the radio where the traffic is queued and sent according to the packet marking.
Product Applicability: C5, C5c Mounting hardware is provided standard for the C5. The C5 hardware is made from stainless steel, including the hose clamp and ground screw. FlexiMount and J-Mount Both the FlexiMount and J-Mount are Steel, Zinc-plated, and powder-coated white. The included hardware is galvanized Steel.
Mimosa radios require 48 volts, but they accept an input range of 44 to 57 volts on a wide variety of pin combinations. An input voltage of -48 Vdc is also acceptable. The Mimosa PoE for C5 provides 56 volts on 2 pairs of wires so there is less voltage drop over long cable runs up to 100 m (328 feet).

It was designed first to protect against surge energy from entering a structure in compliance with electrical codes. There is no surge protection on the C5, PoE or G2, and only the C5 and NID have metal shielded Ethernet inputs. While the Ethernet cable shield can behave like a ground (and many service providers treat it as such), it is not a code-compliant grounding solution for surge currents as the cross-sectional area does not have the current carrying capacity of a larger ground wire that would normally be specified for building safety.

Mimosa Client Help Content Mimosa Clients 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.
After connecting via one of the 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.

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.
Mimosa Client Help Content Mimosa Clients Dashboard The Dashboard The Dashboard contains several panels used to group related items. The status panel at the top of the page shows the link SSID, the link status, Link Uptime since association, and Link Availability since the last reboot. Two of the values on this panel contain an information icon that shows more information when you click or hover over it with your mouse cursor.

Mimosa Client Help Content Mimosa Clients Dashboard 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.

Mimosa Clients Troubleshooting Guide Try changing to the same static values on both router and Mimosa radio (e.g. force 100BaseT or 1000BaseT on both sides). The Ethernet port speed setting is located on the Management Miscellaneous Settings page. If possible, try replacing the PoE Injector in order to determine if the port negotiation issue is with the Radio or the PoE Injector.

Evaluate and adjust the Tx power. Tx power that is too low can result in low SNR, while Tx power that is too high can result in distortion (saturation at the transmitter or receiver). Mimosa recommends setting the Tx power to the level modeled in the Design application, and then making incremental changes up or down to determine the optimal level (lowest PER, highest MCS).
Page 95
Mimosa radios reduce the Modulation Coding Scheme (MCS) in response to PER in a process called Rate Adaptation. PER and MCS are inversely correlated; as PER increases, MCS decreases and vice versa. The effects of this can be seen on the Dashboard in the form of PHY rate changes.

Low Tx/Rx Power The Tx/Rx power per chain is shown on the Client List page on the A5, or on the Dashboard of the C5. Although the A5 transmits on 4 chains to optimize the signal, the C5 will only transmit and receive on a maximum of two chains.

Some third-party routers contain native bandwidth tests. Mimosa has found that some router models and firmware versions are insufficient for testing the full capacity of Mimosa links, leading to skewed results. There are several reasons including: 100 Mbps port limitations, fixed TCP windows, fixed TCP send and receive buffers, CPU capacity limitations, etc.
