Mimosa Client Help ContentMimosa Clients PerformanceCopyright © 2014 Mimosa Page 10Quality of Service (QoS) SupportMimosa radios support four different L2/L3 QoS queues for traffic prioritization. Typically, an upstream router setsvalues 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. While the radio does notfunction as a router, it does respect packet markings assigned by the upstream router.Note that these settings can be set or overridden by either A5 Access Control Lists or ApplicationNote that these settings can be set or overridden by either A5 Access Control Lists or ApplicationPrioritization.Prioritization.The table below lists the four QoS queues and corresponding prioritization values for various traffic markingstandards.Traffic Queue IEEE P802.1p(VLAN CoS Priority) TOS DSCP Mimosa Weighting(% of capacity)BE 0 0-31 0-7 20BK 1 32-63 8-15 10BK 2 64-95 16-23 10BE 3 96-127 24-31 20VI 4 128-159 32-39 30VI 5 160-191 40-47 30VO 6 192-223 48-55 40VO 7 224-255 56-63 40where,BK = Background (lowest priority)BE = Best EffortVI = VideoVO = Voice (highest priority)Mimosa QoS WeightingMimosa radios dynamically allocate link capacity by expanding or contracting each traffic queue based on thecurrent mix of marked traffic. If there is no traffic in a particular queue, that capacity is divided between the otherqueues according to their relative weights. Unmarked traffic is processed in the Best Effort (BE) queue by default.

Mimosa Client Help ContentMimosa Clients Mounting & GroundingCopyright © 2014 Mimosa Page 26Network Interface Device (NID)OverviewThe NID serves two purposes:It was designed first to protect against surge energy from entering a structure in compliance with electrical1.codes. There is no surge protection on the C5, PoE or G2, and only the C5 and NID have metal shieldedEthernet inputs. While the Ethernet cable shield can behave like a ground (and many service providers treat itas such), it is not a code-compliant grounding solution for surge currents as the cross-sectional area does nothave the current carrying capacity of a larger ground wire that would normally be specified for building safety.The NID also serves as a demarcation point for the external portion of service, and provides outdoor technician2.access so that they don’t have to schedule time with a building occupant for testing or troubleshootingbetween the C5 and A5. Some providers charge end users more money if the problem is inside the buildingrather than outside.

Mimosa Client Help ContentMimosa Clients Mounting & GroundingCopyright © 2014 Mimosa Page 27SecurityA security fastener tie point is included at the bottom of the NID to thwart and provide evidence of causaltampering. If an unauthorized party wishes to access the network, they could also cut and re-terminate the Ethernetcable in the absence of a NID. In either case, an they would need to bring their own DHCP router and DC powersupply to access the customer’s router, which is presumably also protected by a suitable firewall. They could accessthe C5 so long as they brought a passive 48V DC power supply, but they would need to know the IP address,password and VLAN if applicable. Most operators filter and manage traffic at upstream routers using VLAN or MACfiltering to prevent unauthorized access such as when end customers do not pay their bill.

The newest datashows up on the right and scrolls to the left over time. You can toggle between the charts by clicking on thenavigation circles at the bottom of the panel. If enabled, click on the cloud icon to view historical data within theManage application.The IP Throughput graph plots three lines representing transmit, receive, and aggregate (summed) throughputs atLayer 2. The results here may differ from those measured using speed test tools, due to protocol overhead andencapsulation. 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 withina 5-second period. Lower values result in higher modulation, while higher values indicate the presence ofinterference and result in lower modulation. Tx PER is an indication that the local radio did not receive an ACK fromthe remote radio, so is forced to retransmit the same information again. Note: PER will be higher upon initial association, and will usually settle within 30-60 seconds. This isNote: PER will be higher upon initial association, and will usually settle within 30-60 seconds. This isbecause association requires that the radios “listen” more carefully for their link partner until they arebecause association requires that the radios “listen” more carefully for their link partner until they arelinked, and this listening period is subject to more interference until Automatic Gain Control (AGC) andlinked, and this listening period is subject to more interference until Automatic Gain Control (AGC) andRate Adaptation (RA) adjust parameters to accommodate the conditions.

Mimosa Client Help ContentMimosa Clients DashboardCopyright © 2014 Mimosa Page 43Reading MIMO Status TablesThe MIMO Status panel contains two tables: Chains and Streams. Chains represent the physical medium (RF Tx/Rxvalues), while Streams represent data. Chains and Streams are not necessarily correlated one to one because theRate Adaptation algorithm may periodically increase or decrease the number of data streams sent over the physicalmedium 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 TableThe Chains table contains 6 values: Tx Power, Rx Power, Rx Noise, SNR, Center Frequency and Polarization(horizontal and vertical). Tx Power is the amount of power applied to each of the MIMO chains.Tx power is divided evenly per chain. Example: 15 dBm Tx power for the Channel results in 12 dBm onTx power is divided evenly per chain. Example: 15 dBm Tx power for the Channel results in 12 dBm oneach on chain. Since power is expressed in dBm, subtract 3 to divide the total power in half.each on chain. Since power is expressed in dBm, subtract 3 to divide the total power in half.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 arebetter (e.g. -90 dBm is better than -80 dBm). Noise sources can be either in close proximity to the local radio, orthey can be remote transmitters pointed back at the local radio.

Mimosa Client Help ContentMimosa Clients DashboardCopyright © 2014 Mimosa Page 44 The signal-to-noise ratio (SNR) is the difference between the Rx Power and Rx Noise, and is a measure of how wellthe local receiver can detect signals from the remote transmitter and clearly discern them from noise. Highervalues 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 bebecause the Tx Power is set lower on the remote transmitter, or because of higher interference levels on thechannel. To resolve this, increase Tx Power or change the channel that has lower SNR. Chain 1 has horizontal polarization, while Chain 2 has vertical polarization. Streams TableThe Streams table contains the Tx MCS index, Tx PHY rate, Rx MCS index, Rx PHY rate, and the Rx EVM for eachstream.The Tx MCS is an indicator of how well the remote radio can receive data from the local transmitter. The Rx MCSindicates 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 affectsThe Modulation Coding Scheme (MCS) represents how much data can be sent at a time, so directly affectspotential throughput represented by the PHY rate. The higher the MCS index (ranging from 0-9), the morepotential throughput represented by the PHY rate. The higher the MCS index (ranging from 0-9), the moredata that can be sent per transmission. A disadvantages of higher MCS indices is that they require higherdata that can be sent per transmission. A disadvantages of higher MCS indices is that they require higherSNR since they are more vulnerable to noise. SNR since they are more vulnerable to noise. The Error Vector Magnitude (EVM) indicates the difference between the actual and expected amplitude and phase ofan incoming signal. Smaller values are better (e.g. -30 dB is better than -10 dB).

Mimosa Client Help ContentMimosa Clients DashboardCopyright © 2014 Mimosa Page 45 Rate Adaptation dynamically adjusts both the MCS and the number of streams depending on RF conditions. Poor RFconditions (i.e. interference) causes PER to increase. PER and MCS are inversely correlated meaning that as PERincreases, MCS decreases and vice versa. The radio usually uses 2 streams, but it may drop to one stream if RF conditions are poor. You may also see thenumber of streams change periodically because of tests that Rate Adaptation performs to optimize performance.This is expected and normal.Related:Client FAQ: What SNR is required for each MCS?Client FAQ: What is the sensitivity for each MCS index?Client FAQ: What's a good EVM?

Mimosa Client Help ContentMimosa Clients Channel & PowerCopyright © 2014 Mimosa Page 46Reading the Spectrum AnalyzerThe Spectrum Analyzer actively scans the spectrum in the background to report on interference sources that mayimpact link performance. Click on the half circle icon in the upper right to toggle the graph's background colorbetween black and white.Channels in use have higher Power Spectral Density (PSD), or amplitude, on the vertical axis, and are shaded indifferent 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). Thecolor 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 frequencyranges that are restricted, manually excluded, or in active use by this link. Note that traffic from the Active Channelis excluded from the display so that noise can be detected.

Mimosa Client Help ContentMimosa Clients Troubleshooting GuideCopyright © 2014 Mimosa Page 86Port Flapping (alternating between 100BaseT and 1000BaseT)It is possible for FM interference on a radio tower to couple into the cable on unshielded cable. If the cable shield isnot connected properly on both sides, the shield can act like an antenna and introduce noise into the circuit. Routerfirmware incompatibilities can also affect Ethernet negotiation at 1000BaseT. Example Event Log MessagesMIMO_EVENT ethernet link downMIMO_EVENT ethernet link up (1000/Full)MIMO_EVENT ethernet link downMIMO_EVENT ethernet link up (100/Full)Troubleshooting Steps:Ensure that high quality shielded CAT6 cable is installed between the Mimosa PoE and Mimosa radio, and that1.the total cable length is 100 meters (328 feet) or less.Ensure that no additional Ethernet surge protection devices are installed between the PoE and Mimosa radio.2.Protection is already included in the Mimosa Radio and PoE. Additional hardware may increase capacitanceand cause instability.Ensure that the electrical ground between radio and tower, and the ground from tower to earth have <53.ohms resistance in total.Test continuity of the CAT6 cable shield from one end of the cable to the other with a digital multimeter.4.Ensure that the cable shield makes contact with both the radio's Ethernet input and PoE output connector5.shells.Ensure that the IP67 Ethernet gland is installed to prevent moisture from entering the cable.6.Test cable wiring integrity with an Ethernet cable tester, and/or use a second cable to rule out an internal7.cable issue.Ensure that the bend radius of the cable does not exceed the manufacturer's specifications. Sharps bends or8.kinks can damage the cable or change the isolation between wire pairs within the cable which can degradeperformance.Repeat the test indoors from router to PoE to the Mimosa radio exhibiting the problem.9.Test for ground loops indoors by installing an EMI filter and/or non-grounded AC adapter between the PoE10.power connector and AC receptacle.Repeat the test indoors from router to PoE to a different Mimosa radio to rule out an Ethernet hardware11.failure if step above fails.Connect a laptop with a 1000BaseT Ethernet port to the PoE to determine if the connection rate is dependent12.upon the connected router. Alternately, connect another switch between the router and PoE

Mimosa Client Help ContentMimosa Clients Troubleshooting GuideCopyright © 2014 Mimosa Page 87Try changing to the same static values on both router and Mimosa radio (e.g. force 100BaseT or 1000BaseT13.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 Radio14.or the PoE Injector.

Mimosa Client Help ContentMimosa Clients Troubleshooting GuideCopyright © 2014 Mimosa Page 88Troubleshooting Radio AssociationRadios may not associate for a number of reasons. Most commonly, because they are configured incorrectly orbecause of insufficient SNR.NoteNote: Mimosa radios must be unlocked before operation. For help with the unlock process, click here.: Mimosa radios must be unlocked before operation. For help with the unlock process, click here.Check the Radio Configuration on Both Sides of the LinkLog into the radio GUI and click Wireless > Link.1.Ensure that the SSID and Encryption Key are the same on both sides of the radio link.2.Ensure that the same wireless protocol is selected: WiFi Interop or SRS (formerly, GPS-Sync).3.Ensure that the same firmware is installed on both sides of the radio link.4. If indoors, point the radios away from each other and turn down the power.While testing inside a room, point the radios toward the ceiling and set Tx power to the lowest possible1.setting. This will prevent the receivers from saturating.Check for interference on the Spectrum AnalyzerLog into the radio GUI and click Wireless > Channel & Power.1.Look for interference that overlaps the selected center frequencies.2.If interference is found, there are two options:3.a) click on the Auto Channel dropdown to enable automatic channel selection and/or channel widthadjustment; orb) change the channel manually to avoid the interference.Check for interference on PER GraphLog in the C5 GUI and click on Overview > Dashboard.1.On the Performance Graph, click on the navigation circles at the bottom to display "PHY PER".2.Look for persistent PER above 5%.3.If PER is greater than 5% for either side of the link, there are two options that you can take at the AP:4.a) click on the Auto Channel dropdown to enable automatic channel selection and/or channel widthadjustment; orb) change the channel manually to avoid the noise.

If not, click the2.plus "+" button to enter it's IP address. If Rogue DHCP Server Protection is not enabled, proceed to the nextstep. Turn on VLAN PassthroughLog into the A5 radio GUI and click Preferences > Management.1.If Management VLAN is enabled, ensure that VLAN Passthrough is also enabled.2.Check the C5 IP Mode settingsLog into the C5 GUI and ensure that the IP mode is set to "DHCP + Static Failover" (Preferences >1.Management). Ensure there is no firmware mismatch between A5 and C5Log into the A5 and C5 individually. Configure your computer to an IP address within the range of the radio's1.static fallback IP address to access it locally.Ensure the reported firmware version is the same (Preferences > Firmware & Reset) on both A5 and C5.2.

$Mimosa Client Help ContentMimosa Clients Troubleshooting GuideCopyright © 2014 Mimosa Page 90Low Signal-to-Noise Ratio (SNR)The signal-to-noise ratio (SNR) is the single most important indicator of link health. It represents the magnitudedifference between the Rx power and Rx Noise, which is positively correlated with the modulation coding scheme(MCS) index. Up to a point, the higher the SNR, the higher the MCS and resulting throughput. Troubleshooting StepsEnsure that antennas are optimally aligned to achieve the highest Rx power value across the RF link.1.Ensure line of site between radios is clear of obstructions that may block the Fresnel zone. Obstructions may2.cause reflections/refractions that appear as noise.Choose the clearest RF channel(s) available. Interference (noise) on the same frequency can increase PER3.because the receiving radio does not have sufficient SNR.Select narrower channel widths to increase spectral density.4.Evaluate and adjust the Tx power. Tx power that is too low can result in low SNR, while Tx power that is too5.high can result in distortion (saturation at the transmitter or receiver). Mimosa recommends setting the Txpower to the level modeled in the Design application, and then making incremental changes up or down todetermine the optimal level (lowest PER, highest MCS).Consider installing a higher gain antenna (A5c).6.Related:Client Troubleshooting: High PER - Troubleshooting steps for high packet error rate$

$Mimosa Client Help ContentMimosa Clients Troubleshooting GuideCopyright © 2014 Mimosa Page 91High Packet Error Rate (PER)The Packet Error Rate (PER) is the number of packets with errors divided by the total number of packets sent withina 5-second period. Lower values result in higher modulation, while higher values indicate the presence ofinterference and result in lower modulation. Tx PER is an indication that the local radio did not receive an ACK fromthe remote radio, so is forced to retransmit the same information again. Rx PER is a value sent from the remoteradio to the local radio in management frames.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 beseen on the Dashboard in the form of PHY rate changes. Because data must be retransmitted, time-sensitiveapplications such as VoIP data services may be affected by spikes in PER or sustained high PER.Troubleshooting StepsEnsure the antennas are optimally aligned to achieve the highest RX power value across the RF link. A low1.signal-to-noise ratio (SNR) can lead to higher PER.Ensure line of site between radios is clear of obstructions that may block the Fresnel zone. Obstructions may2.cause reflections/refractions that appear as noise.Choose the clearest RF channel available. Interference (noise) on the same frequency can increase PER3.because the receiving radio does not have sufficient SNR.Evaluate and adjust the Tx power.
