Default IP Address

Mimosa backhaul radios can be accessed either via the wired interface or the 2.4 GHz wireless interface (if

applicable). An internal bridge connects the two interfaces. Each interface is assigned a default IP address (see table

below), and both addresses respond via either interface. The wired interface can either be set manually to a static

IP or changed dynamically via DHCP. The wireless interface IP can not be changed.

Notes:

1. The wired Ethernet interface is configured by default to use DHCP with a static failover to the IP address

in the table below.

2. If applying power to the radio without populating the PoE Data port, the recovery page will be shown via

the wireless interface for 5 minutes. This behavior is normal and is a part of the Reset process. In this

case, the default wireless IP will be 192.168.26.1.

IP Address Discovery

Run the following command from the command line to discover the IP addresses of any directly connected Mimosa

devices. The string "20:B5:C6" is an Organizationally Unique Identifier (OUI), which is the first half of the MAC

address assigned to Mimosa devices. After executing the command, the IP address will be shown for each device.

Windows / DOS:

arp -a | findstr 20:B5:C6

Mac / Linux:

arp -a | grep 20:B5:C6

Port Scan

Run the following command from the command line to discover the port of any directly connected Mimosa devices.

This is especially useful if the port has been changed, and you do not remember the port number.

No Command Line Interface (CLI) Access

There is no user-accessible method for SSH or telnet to Mimosa devices. Mimosa Support is the only party capable

of accessing the shell, and only after installation of an RSA certificate.

Mimosa disables the CLI by default due to security, support, and regulatory compliance concerns:

●

Prevents installation of non-Mimosa operating systems that can lead to unsupported configuration changes especially related to regulatory compliance.

●

Protects devices, and data passing across them, from unauthorized access.

●

Deters counterfeiting and reverse engineering of Mimosa's intellectual property.

Mimosa Backhaul Help Content Mimosa Backhaul Performance

MAC Throughput

MAC throughput is shown on the Dashboard Signal Meter as "MAC Tx/Rx (Mbps)". The acronym MAC is short for

"Media Access Control", which is one of two sub-layers within Layer 2 of the Open Systems Interconnect (OSI)

model. Layer 2 is responsible for forward error correction and management of the channel (e.g. flow control,

collision prevention, and TDMA timing). These functions are necessary for the network to operate properly, but they

add processing overhead which results in lower throughput than at the PHY (Layer 1).

TDMA Settings Affect MAC Throughput

On Mimosa radios, MAC throughput can be adjusted since it is a function of the configurable TDMA settings: TDMA

Traffic Split and TDMA Transmit Window. When using TDMA, a time-based MAC protocol, each radio takes turns

sending and receiving. The time allocated to each side for transmission is controlled with the TDMA Traffic Split. This

value can be set in the device GUI to 50/50, 75/25 or 25/75 (in Auto mode). The Traffic Split slash notation follows

the convention: Local Tx Window / Remote Tx Window. The numbers on either side of the slash ("/"), represent the

Duty Cycle for each side.

MAC efficiency varies with the TDMA Window size (2/4/8 ms). Larger windows allow for a larger ratio of data to the

required overhead that accompanies it. Conversely, smaller windows allow for less data to be transmitted at a time

which is necessary for applications that are sensitive to latency (such as VoIP), but the overhead is the same.

Calculating MAC Throughput Based on PHY Rate

The formulas for determining MAC throughput in either direction are the following:

●

MAC Tx Throughput = Tx PHY rate * Tx MAC Duty Cycle * MAC Efficiency

●

MAC Rx Throughput = Rx PHY rate * Rx MAC Duty Cycle * MAC Efficiency

Where:

Tx/Rx MAC Duty Cycle represents the transmit window (25%, 50%, or 75%) based on TDMA Traffic Split.1.

MAC Efficiency is a function of the TDMA Transmit Window from the table below.2.

Transmit Window MAC Efficiency

8 ms 90 %

4 ms 80 %

2 ms 70 %

Example:

Mimosa Backhaul Help Content Mimosa Backhaul Performance

Tx MAC Throughput (Mbps) = 1560 * 50% * 80% = 624 Mbps

Rx MAC Throughput (Mbps) = 1300 * 50% * 80% = 520 Mbps

Note: The built-in Bandwidth test on the radio (Diagnostics > Tests > Bandwidth) displays UDP results,

which should closely match the MAC Throughput shown on the Dashboard. The UDP protocol is

connection-less and unidirectional, whereas the TCP protocol requires bi-directional communication and

acknowledgements (ACK) from the remote host in response to a transmission.

󾺠Backhaul Maximum Tx Power

The maximum transmit power that you can select is limited by product specifications, the number of channels in

use, and maximum EIRP limits.

Maximum Transmitter Power

Mimosa Backhaul radios are capable of transmitting at the power levels in the table below. With the B5 and B5c,

total power can be divided equally (preferred) or unequally (if necessary) between the two channels. Once power is

selected for a particular channel, it is then divided equally between H and V chains.

Maximum EIRP Limits (5 GHz)

Local laws may restrict maximum EIRP for certain frequency ranges. The chart below shows restrictions in the

United States.

The equations for calculating the maximum Tx power for each band are the following:

One Channel:

Max Tx Power (dBm) = EIRP limit (dBm) - Antenna Gain (dBi)

Mimosa Backhaul Help Content Mimosa Backhaul Performance

Two Channels:

Max Tx Power (dBm) = EIRP limit (dBm) - Antenna Gain (dBi) - 3 dBm

Example 1 - B5c, 30 dBi, 2 Channels, U-NII-1:

The limits in the chart above for U-NII-1 are currently 40 dBm. After entering the 30 dBi antenna gain on the B5c, Tx

power will be limited to 7 dBm (40 dBm - 30 dBi - 3 dBm).

Example 2 - B5c, 30 dBi, 1 Channel, U-NII-2:

The limits in the chart above for U-NII-2 are currently 30 dBm. After entering the 30 dBi antenna gain on the B5c, Tx

power will be limited to 0 dBm (30 dBm - 30 dBi).

Backhaul Tx Power Optimization

Should I always choose the maximum Tx Power setting for best performance?

Not necessarily. The answer depends on the maximum achievable signal to noise ratio (SNR) for a given link. You

may see a tooltip on the Channel & Power page to this effect like the one below.

Background

A theoretical amplifier would apply gain (the output to input power ratio) linearly to any input signal. For instance, a

10 dB amplifier should amplify a 0 dBm signal to 10 dBm, a 10 dBm signal to 20 dBm, and so on. However, typical

amplifiers are not perfectly linear for all input power. Above a certain power level, the input signal begins to distort

during amplification (in the Compression Region). A distorted output signal from a transmitter is more difficult for

the receiver to interpret, leading to higher EVM and lower MCS.

Recommendations

If the link is short (high Rx Signal Strength), or if SNR is high, select lower Tx Power to allow the transmitting

amplifier to operate within it's Linear Region and avoid distortion in the Compression Region.

If the link is long (low Rx Signal Strength), or if SNR is low, select higher Tx Power and accept some distortion in

Mimosa Backhaul Help Content Mimosa Backhaul Performance

favor of higher SNR. This is because SNR at the receiver limits the MCS more than the distortion from the Tx

amplifier. The table below shows the maximum recommended Tx Power settings for a given SNR to achieve the highest MCS

index. Auto Everything dynamically adjusts Tx Power, or these steps should be followed in manual mode:

Note the lowest SNR on Dashboard > MIMO Status.1.

Find the SNR in the first column of the table below.2.

Set Tx Power to a value in the second or third column, depending on the number of channels used.3.

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.

Examples:

●

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. This difference is caused by noise.

When analyzing EVM, the lower the number the better.

Quality of Service (QoS) Support

Mimosa backhaul 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. While the

radio does not function as a router, it does respect packet markings assigned by the upstream router.

The table below lists the four QoS queues and corresponding prioritization values for various traffic marking

standards.

BE 0 0-31 0-7 20

BK 1 32-63 8-15 10

Mimosa QoS Weighting

Mimosa radios dynamically allocate link capacity by expanding or contracting each traffic queue based on the

current mix of marked traffic. If there is no traffic in a particular queue, that capacity is divided between the other

queues according to their relative weights. Unmarked traffic is processed in the Best Effort (BE) queue by default.

Link Latency

Product Applicability: B5/B5c, B5-Lite

Link latency is the delay between the time a packet enters the local radio and exits the remote radio in one

direction. In many cases, constraining latency across one link (or more) is a requirement for providing services such

as VoIP that are more sensitive to packet arrival times.

Average link latency is configured with the TDMA Window Size. Available options include 2, 4, and 8 ms. Operators

should take into account the total number of hops when setting TDMA Window Size to ensure that total latency

meets requirements.

In practice, the average latency (in the presence of noise and resulting retries) in one direction is 1.25 * the TDMA

Window Size:

1-Way Latency (ms) = 1.25 * TDMA Window Size (2/4/8 ms)

For example, 2 hops (back-to-back links) with a 4 ms TDMA Window would result in 10 ms average latency (2 hops *

4 ms * 1.25 = 10 ms) in one direction.

Latency tests are usually performed from a command line or embedded interface with the ping command, which

returns the round trip time (RTT) across the link and back. The implication is that ping results will be double of the 1-

Way Latency.

Round Trip Time (ms) = 2.5 * TDMA Window Size (2/4/8 ms)

Note that RF interference, and resulting packet errors (indicated as PER on the Dashboard), can lead to retries and

more round-trips to complete a ping.

Asymmetric TDMA Traffic splits (75/25 or 25/75) have a negligible affect on RTT since the total time always adds up

to one full cycle.

Mimosa Backhaul Help Content Mimosa Backhaul Performance

TCP Performance

Mimosa Backhaul radios are designed to pass many data streams, and although a Mimosa link may have a full

gigabit of capacity, a single TCP stream will not saturate the link. However, multiple TCP streams can saturate the

link, and better represent typical backhaul applications where multiple TCP streams occur asynchronously. This can

be demonstrated by comparing single and multiple streams when testing throughput with iPerf. The reasons for this

difference are described below.

TCP Protocol Background

Transmission Control Protocol (TCP) is a connection-based protocol that requires an acknowledgement for each data

packet sent between hosts to ensure reliable communication. A sender sends a packet to a receiver, and the

receiver sends an acknowledgement back to the sender. If the sender does not receive an acknowledgement, it will

retransmit the original packet.

Each host participating in the TCP connection also has a default TCP Window Size (or TCP Receive Window) which

defines the amount of data that each host can accept without acknowledging the sender. TCP transmits data up to

the TCP Window Size and then waits for an acknowledgement, so the full capacity of the link may not be used.

Factors Affecting TCP Throughput

TCP connections, such as for file transfers and database queries, are affected by these controllable factors:

●

The TCP Window Size can be adjusted manually for each host that participates in the TCP connection. Most operating systems adjust the TCP Window Size dynamically with maximum send and receive windows that can be overridden, or with heuristics and scaling algorithms than can be modified or disabled. Consult your operating system documentation for more information. Throughput test software in routers and in desktop applications may artificially limit the TCP Window, so be sure to understand what values are applied before drawing conclusions from the results they provide.

●

Internal and external network latency may also be introduced by other devices such as switches and routers between each host and the Mimosa Backhaul radios. Test round trip times between devices to determine their impact on overall latency. Link latency, or round-trip time (RTT), across the Mimosa link can be reduced in the following ways:

●

Fixed TDMA: Latency can be controlled by selecting an appropriate TDMA Window setting (2/4/8 ms). The round trip time (RTT) can be calculated as described within the Calculating Link Latency article, and measured empirically with ping results.

●

Auto TDMA: This mode results in the lowest latency, but it is not compatible with GPS synchronized spectrum sharing. The transmit window is as long as is necessary (up to 4ms) to send whatever data is available at the time, and then control is passed back to the other side. Select "Auto" as the gender and traffic split (Wireless > Link > TDMA Configuration) on the AP to operate in this mode.

●

Latency can also occur if the link is already saturated, and some TCP streams are queued while waiting for access to the medium. If possible, increase channel width to add capacity, or improve SNR to enable higher order modulation.

●

The Packet Error Rate (PER) can cause variations in latency because packets received with errors must be resent from radio to radio at the MAC layer. This latency can cause TCP to reduce the maximum transmit window, so care should be taken to follow the Backhaul RF Tuning Process to minimize (and stabilize) PER before attempting throughput tests.

Mimosa Backhaul Help Content Mimosa Backhaul Performance

●

Packet loss can occur on Ethernet between hosts and Mimosa radios due to cabling or port problems, the amount of which is detected and reported by most commercial routers. Packet loss can also occur on routers due to lack of QoS policies, or in the presence of rate-limits that may be applied.

Calculating Maximum TCP Throughput (Single TCP Stream)

This formula can be used to calculate the maximum TCP throughput for a single stream given TCP Window size and

Latency:

TCP Throughput (bps) = TCP Window Size (bits) / Latency (seconds)

Example (64 KB TCP Window Size, 10 ms Latency)

Take the TCP Window Size in KB and convert to bits in Base 2 (binary):1.

64 KB * 1024 bytes/KB * 8 bits/Byte = 524288 bits

Take the latency in milliseconds and convert to seconds:2.

10 ms / 1000 ms/sec = 0.010 sec

Substitute the results from above into the original equation:3.

Throughput (bps) = 524288 bits / 0.010 seconds = 52428800 bps or 52.4 Mbps

Calculating Optimal TCP Window Size

This formula can be used to calculate the optimal TCP Window size if the MAC Throughput and the latency are

known:

TCP Window (KB) = [ MAC Throughput (Mbps) * RTT (ms) ] / 8192 bits/KB

Example (500 Mbps MAC Throughput, 10 ms latency)

(500 Mbps * 10 ms) / 8192 bits/KB = ~610 KB

Calculating Maximum Latency for a Desired Throughput

This formula can be used to calculate the maximum tolerable latency to achieve a desired throughput:

TCP Window Size (bits) / TCP Throughput (bps) = Latency (seconds)

Example (500 Mbps Throughput, 625 KB TCP Window Size)

(625 KB * 8192 bits/KB) / (500 Mbps * 1000000 bits/Mbit) = 0.0102 seconds or 10.2 ms.

Backhaul Maximum Operating Distance

The maximum operating distance (or range) you can expect to achieve largely depends on your design

requirements for throughput and reliability. Throughput on longer links is constrained primarily by the physics of

Auto Everything

Product Applicability: B5/B5c, B5-Lite

Auto Everything (AE) is a feature that makes automatic adjustments to link settings (channels, channel width,

transmit power, and single or dual channel modes) in response to changes in the RF spectrum with the goal

of achieving balance between link reliability and capacity. The algorithm calculates prospective quality of

available channels, and then ranks each based on the expected achievable link rate at the physical layer (PHY).

Auto Everything comprises the following four sub-processes:

●

INITIAL SETUP - Upon powering the radios, the Access Point (AP) is automatically set to a 1x20 MHz channel and then attempts to associate with the Station. Upon association, a quick channel analysis is initiated to find the clearest channels within the available spectrum. The radios are then set to use the best channel(s).

●

HEALTH CHECK - Monitors channel quality in the background frequently (HEALTH CHECK) and changes channels if the link consistently has a high Packet Error Rate (PER). If the HEALTH CHECK fails, the radio will change to the next best available channels from the list generated during full analysis.

●

CONSTANT OPTIMIZATION - Changes to better channels (higher PHY rate), when available, even if the current channels have sufficiently low PER. Optimization often also involves increasing channel width, and/or changing from single channel to dual channel mode.

●

POWER SELECTION - Calculates and sets optimal transmit power while complying with regulatory restrictions.

Frequency of Channel Changes

●

Interference: If the link experiences high PER consistently for approximately 2 minutes, the Access Point will select the best alternative channel(s). If link health is still poor after the first change, Auto Everything will continue to select the next best channel from its spectrum options. It will continue to do this 6 times, for a total of 12 minutes. If after 12 minutes, it still cannot find a channel with sufficiently low PER, it will revert to INITIAL SETUP mode and attempt to associated on a clean 1x20 channel.

●

Clearer Channel Identification: Auto Everything strives to keep the radio on the clearest channel or channels. Auto Everything performs background scans and monitors those channels which have considerably better conditions than the existing channels in preparation for their need. When channel change is induced due to finding a clearer channel (and not due to interference), the channel change occurs after ten background analysis cycles because the change is a non-critical improvement to link health.

Channel Analysis

Auto Everything calculates expected throughput for each channel using spectrum data from both sides of the link.

The AP periodically pulls analysis data from the STATION and selects channels that are clear for both radios. If Auto

Everything is unable to find a mutually clean channel for both sides of a link, it will choose a 1x FD mode. Channel

analysis runs as a background process which constantly updates the list of good channels based on changes in

spectrum.

Adjustment to B5c EIRP

Auto Everything will recalculate the maximum allowed transmit power based upon the antenna gain (B5c only). Any

change to antenna gain (Wireless > Channel & Power > Channel & Power Settings > Antenna Gain) will cause AE to

recalculate the new max allowed transmit power during channel analysis.

Mimosa Backhaul Help Content Mimosa Backhaul Performance

Turning Off Auto Everything

Auto Everything can be turned off by selecting "Off (Manual)" in the drop-down box. If turned off, Auto

Everything will stop monitoring channel health and will no longer change channels. However, the AE process will

continue performing channel analysis in the background and maintaining a list of best channels for when AE is re-

enabled. Recommendations from this channel analysis are available on the Channel & Power page for manual

selection.

Auto Everything and Excluded Channels

Auto Everything can be prevented from using specific frequency range(s) by adding them to the exclusion list on the

AP (Wireless > Channel & Power > Exclusions & Restrictions), and then saving. The station will inherit the same

exclusions from the AP during association. This will restart the current background channel analysis process and

exclude both the newly added channels and any channels on the existing exclusion list. Auto Everything will also

change the current channels if the new exclusion channels make them invalid. Similarly, removing channels from

the exclusion list will restart the background channel analysis to make use of newly available channels.

Mimosa Backhaul Help Content Mimosa Backhaul Performance

Dual Link

Product Applicability: B5, B5c, B11

Upon sensing interference on one channel that would cause the entire link to reduce modulation, the Dual Link

feature dynamically routes traffic to the channel with the lower packet error rate (PER) to improve noise immunity

and prevent packet loss.

This is accomplished by turning off the receive chains on the channel that is suffering the most (in two channel

mode). This allows the radio to receive at the highest MCS rate on the channel with lower interference, and the radio

continues to transmit on both channels.

Mimosa Backhaul Help Content Mimosa Backhaul Collocation

Integrated GPS and GLONASS Receiver

Product Applicability: B5/B5c, B11

The B5, B5c and B11 include an integrated receiver that receives signals from both GPS and GLONASS satellites.

This effectively doubles the number of available satellites to obtain a lock over a pure GPS receiver. The receiver is

able to provide accurate latitude and longitude information that you may use in conjunction with Mimosa Cloud

Services to show the position of your devices overlaid on a map for planning and management purposes.

The GPS/GLONASS receiver is also required for timing synchronization to allow TDMA timing slots to operate

correctly between devices. GPS timing alone is not sufficient to achieve this, as over time the accuracy is

compromised and synchronization between devices will drift. To ensure reliable time synchronization, the product

includes a GPS-Disciplined Oscillator (GPS-DO) with 3 ppb (parts per billion), or 40 ns accuracy. This allows devices

to stay synchronized from a timing perspective without requiring any form of communication with nearby radios or

to the cloud. This also means that even if there are multiple users of Mimosa radios in a single site, that these can

also be synchronized for TDMA operation.

Note that the B5-Lite does not include a GPS receiver.

Collocation with Other Radios

Product Applicability: B5/B5c, B11

What are the guidelines for collocation with other Mimosa radios?

Up to four (4) Mimosa B5, B5c or B11 radios are designed work together on the same tower, even on the same

channel(s), because they are synchronized via GPS. We recommend 80-90° angular separation and equal Rx power

per site for maximum performance.

Can I collocate at a site where Mimosa radios are on separate towers?

Yes, all Mimosa radios at the same site (even on separate towers) can be collocated and share frequencies so long

as they are configured with the same TDMA settings.

What are the guidelines for collocation with non-Mimosa radios?

Other non-Mimosa radios on the same tower may not use GPS synchronization in the same way, or at all, so some

general rules of thumb apply. Ensure three meters (or ten feet) of physical separation, greater than 30° angular

separation, and 20-30 MHz of frequency separation depending on the PSD mask of the neighboring radio. The B5's

built-in Spectrum Analyzer can be used to select channels with the lowest amount of noise.

Can Mimosa synchronize with non-Mimosa radios?

No, Mimosa radios do not synchronize with any non-Mimosa radios.

Mimosa Backhaul Help Content Mimosa Backhaul Collocation

Collocating with another operator

Product Applicability: B5/B5c, B11

As more Mimosa radios are deployed, they will commonly show up in Site Survey results. The TDMA and Collocation

Synchronization White Paper describes how to design your own collocated network with devices that you control,

but it is also possible to collocate with other radios that you do not control by choosing compatible TDMA settings.

Use Site Surveys

Use the Site Survey feature (Wireless > Site Survey) to list Access Points and their TDMA settings. Once you know

the TDMA settings of other local Mimosa radios, you can choose to coordinate by selecting the same Gender, Traffic

Split and TDMA Windows without having to communicate with the other party.

In the example below, the radios that have higher signal strength (-51 and -40) are probably local, and are likely to

cause interference unless you are willing to adjust your TDMA settings to match, or select an entirely different

channel. The radio that has lower signal strength (-79) is probably a remote AP and can be ignored.

Choose Compatible TDMA Settings

Navigate to TDMA Settings (Wireless > Link) on your radio and select the same settings as the other local radios on

the same tower. In the example below, the Gender, Traffic Split and TDMA window were selected for compatibility

with the TDMA settings of the radios in the Site Survey results above.

Backhaul Relay Connection

Two Backhaul radios can be connected back-to-back without a switch or router. This is accomplished by inserting

the same Ethernet cable into the LAN ports of both PoE injectors. The example below shows relay connections:

Radio 1 - PoE 1 - Ethernet Cable - PoE 2 - Radio 2.

There is a small amount of memory within each of the radio's transmit buffer queue. If both radios are receiving at

the same time, they forward packets out to Ethernet, which will go in the other radio's transmit queue. When it

comes time to transmit, data frames are taken from the Ethernet transmit queue, the appropriate wireless

aggregation is applied, and then the packets are sent over-the-air.

Mimosa Backhaul Product Family Compatibility

B5 and B5c

The B5 and B5c are compatible and can be used in a link together. They are built on an identical hardware and

software platform, with the only differences being the physical enclosure, the use of external connectors and the

addition of antenna gain selection in firmware for B5c.

The selection between a B5 and B5c depends on the application. The B5c allows you to leverage an existing dish

installation and may be better for use on longer links. When distance is less of a concern, B5 is recommended due to

smaller footprint and low weight making it simple to install. Mimosa's free Design application can be used to model

the different performance parameters of each product to aid in selection.

B5-Lite

The B5-Lite is not compatible with the B5 or B5c because the B5-Lite does not contain GPS for timing, and has 45

degree dual-slant polarization.

B11

The B11 is compatible with other Mimosa B11 radios only.

Not compatible with other brands

They do not support point-to-multipoint (PTMP) operation.

Mimosa Backhaul Help Content Mimosa Backhaul Antennas & Coaxial Cables

B5c Antenna Compatibility

The B5c has a frequency range of 4900-6000 MHz. Any high-quality antenna optimized for these frequencies will

work.

The Mimosa B5c was designed to achieve the published performance with cross-polar isolation of 20 dB, primarily

because the MIMO processor can discern between signals well at this level. Increasing the cross-polar isolation will

not improve capacity or throughput.

Tip: Some antennas that are rated for “5 GHz” may not cover the entire band. It is common to see

antennas that are specified to work from 5.45 to 5.85 GHz. They may not operate well, or at all, outside of

their specified range of operation.

Recommended RF Cable for B5c

As a best practice, ensure that cable specifications are available during the design process, and that the total

insertion loss from cable and connectors is included in the link budget.

Mimosa recommends the following specifications for coaxial cables to connect an antenna to the B5c:

●

Double-shielded, 5 GHz-rated, 50-Ohm, Low Loss

●

Outdoor-rated (UV-stabilized)

●

Inner Conductor: solid 2.74 mm (0.108 inch)

●

Dielectric: Foam

●

Length: less than 2 m / 6.6 feet

●

Connectors:

●

Type N Male for connection to B5c

●

Type N Male or RP-SMA Male depending on antenna connector

Please follow the cable manufacturer's recommended bend radius guideline to prevent damage that could lead to

additional loss.

4x4 MIMO with Two Antenna Connectors

The B5/B5c has only two antenna connectors, one for each polarization: horizontal and vertical. The four MIMO

streams are divided both by frequency and polarization. Streams with the same polarization enter an RF combiner

circuit before heading to one of the antenna connectors. The radio at the far end of the link can discern between

frequencies with the same polarization.

Double-slant (45-degree) Antenna Offset

Some users ask if rotating the B5c antenna reduces interference by 3 dB.

In the presence of rain, vertically polarized waves attenuate less than horizontal polarized waves. Rotating the

vertical polarization to be more horizontal would normalize the performance between the two polarizations during

rain events, but it would also result in lower overall performance because of the additional rain fade.

Mimosa has implemented a software Transmit Power Control (TPC) algorithm that attempts to equalize Rx signal

strength across the 4 chains if they are unequal.

For these reasons, Mimosa normally recommends maintaining standard antenna orientation (horizontal polarization

parallel with ground, vertical polarization perpendicular to ground) when using the B5/B5c. This especially applies

to longer backhaul links in areas that experience heavy precipitation.

Traffic Handling

Layer 2 Bridge

Mimosa Backhaul products are designed to operate as a Layer 2 transparent bridge (a virtual wire) for maximum

performance. The radios simply pass all traffic, regardless of type. However, they do support traffic prioritization

with four (4) quality of service (QoS) queues.

Multicast

Mimosa Backhaul radios function as a transparent Layer 2 bridge and forward all multicast traffic (i.e. 224.0.0.5 all

OSPF routers, 224.0.0.6 all DRs, etc.). They do not perform IGMP snooping to first determine if receiver(s) are on the

far end of the network.

Jumbo Frames

The default MTU size is 1500 bytes, but there is no MTU adjustment on the UI. Mimosa backhaul radios support

"baby jumbo" frames up to 3200 bytes without fragmentation in certain modes and modulation levels.

IPsec Tunnels

Mimosa Backhaul radios function as a transparent Layer 2 bridge and forward all traffic including IPsec. The radio

does not participate in IPsec connections and does not act as a VPN termination point. The radio can be configured

to use HTTPS and a VLAN ID for more secure management, however.

U-NII-2 and DFS Support

Product Applicability: B5, B5c. B5-Lite

Mimosa 5 GHz radios support U-NII-2 operation and comply with DFS requirements. When a DFS channel is selected,

there is a mandatory 60-second waiting period where the device listens for radar before association on that

particular channel. In the EU, there is a mandatory 10-minute waiting period for the 5600-5650 TDWR band.

If a qualifying radar signature is detected, the radio will comply with DFS requirements by vacating the channel for

30 minutes. For this reason, Mimosa recommends the use of Dual-Channel mode with the secondary channel on a

non-DFS channel (U-NII-1 or U-NII-3) so that traffic will be routed over the second channel and no link down time is

incurred.

Instead of specifying alternate frequency selections in the case of a DFS hit, Mimosa implemented frequency

"Exclusions" that are set on the Channel & Power page. Exclusions are used to mark frequencies that should be

avoided, leaving the remainder of the spectrum available for automatic selection based on favorable RF conditions.

In the dual channel modes, channels may be contiguous or non-contiguous. There is no self-interference with

contiguous channels. Each channel's center frequency can be set independently. There are some restrictions,

however:

The channels must not overlap, but they can be contiguous without self-interference.1.

Both channels must use the same channel width.2.

Neither channel can overlap excluded bands (government restricted or manually excluded).3.

To provide an example of the flexibility this approach, if planning a link requiring 40 MHz of channel width, this could

be either configured as a single 40 MHz channel, or 2 x 20 MHz channels. The 2 x 20 MHz channels would be a good

option if a clean contiguous 40 MHz of spectrum is unavailable and some resiliency to RF interference is desired,

particularly in regions where DFS is a requirement.

Frequency Diversity (FD) modes allow different Tx channels on each side of a link. This is useful when there isn't a

channel that is mutually suitable for both sides.

Power over Ethernet Specifications

Radio Voltage Input Specifications

Product Applicability: B5/B5c, B5-Lite, B11

Mimosa backhaul radios comply with the 802.3at PoE+ standard. While the radio’s nominal operating voltage is 48

volts, it accepts an input voltage range of 44 to 57 volts on a wide variety of pin combinations. An input voltage of -

48 Vdc is also acceptable.

The included PoE injector was designed to compensate for voltage drops even over the longest cable runs allowed

by the CAT6 standard, less protection circuit losses which net to 100 m (328 feet).

PoE Injector Output Specifications

Mimosa backhaul radios will work with most 802.3at-compliant, 48V PoE adapters. Mimosa recommends the use of

the Mimosa provided PoE adapter in order to ensure maximum throughput1, protection in the event of lightning

strike, and to maintain product warranty.

Input Surge Protection

Product Applicability: B5/B5c, B11

The Mimosa POE is designed to protect connected equipment against voltage and current surges in two ways:

●

Transformer isolation between the two Ethernet ports; and

●

Gas Discharge Tubes (GDTs) on the DATA+POE port.

In case of lightning, GDTs become a virtual short, diverting surge current and voltage to ground and away from

connected equipment. Other PoE’s may not have these protections which could lead to equipment damage during a

lightning event.

We do not recommend any additional surge protection devices placed between the Mimosa POE and radio because

the increased capacitance may cause port flapping between 100BaseT and 1000BaseT.

Input Voltage Range

Product Applicability: B5/B5c, B5-Lite, B11

The Mimosa PoE provides power over all four pairs of wires so there is less voltage drop over a long cable run.

Voltage is provided from the Mimosa PoE at 56 Vdc instead of the nominal 48 Vdc for the same reason, although

Mimosa Backhaul radios accept a wider input voltage range (44-57 Vdc). An input voltage of -48 Vdc is also

acceptable (see below).

Reverse Polarity Protection

Product Applicability: B5/B5c, B5-Lite, B11

All Mimosa radios include a diode bridge circuit which corrects for reverse polarity on the power inputs, and

improves compatibility with 3rd-party 802.3at-compliant PoE injectors and switches that meet the power

specifications2.

Table 1 below shows valid combinations of +VE and -VE to the B5/B5c on either 2 or 4 wire pairs. All of the

Enclosure Ratings

The IP is short for International Protection Marking described in IEC standard 60529. This standard classifies and

rates the degree of protection provided against the intrusion of solid objects and liquids into electrical enclosures.

The two numbers that follow are used to specify the degree of protection. The higher the number, the better the

protection. The first number refers to protection against solid objects. The second number refers to protection

against against liquids.

IP67 (B5/B5c, B11)

●

The 6 rating means that the enclosure is totally protected against dust.

●

The 7 rating means that the enclosure is protected against the effect of immersion between 15 cm and 1m, although Mimosa does not recommend submerging any of its products.

IP55 (B5-Lite)

●

The 5 rating means that the enclosure allows some dust to enter, but not in sufficient quantity to interfere with satisfactory operation of the equipment.

●

The 5 rating means that the enclosure is protected against the effect of water projected by a nozzle (6.3 mm) against the enclosure from any direction.

Protective Vent

Product Applicability: B5/B5c, B11

The protective vent on the bottom of the B5/B5c is designed to reduce stress on the enclosure seals by constantly

equalizing the difference in pressure between the inside of the enclosure and the immediate environment. The vent

works by allowing air and other gases to pass through its microporous ePTFE membrane freely but stops liquids, dirt

and other contaminants from entering the enclosure.

Mounting Hardware

Product Applicability: B5/B5c, B5-Lite, B11

Mounting hardware is provided standard for both the B5/B5c, B5-Lite and B11.

The B5 Bracket Assembly and Pole Mount included with the B5 are made from galvanized steel. Each are coated first

with zinc for corrosion protection, and then a white powder coat is applied. The bolts used to attach the Pole Mount

may cause surface scratches to the white powder coat, but will not impact the corrosion resistance given the two

layers of protective coatings. Mimosa does not recommend the use of additional washers. Screws holding on the

back cover are stainless steel.

The B5c hardware is made from stainless steel, including the hose clamps, ground screw, and cover screws.

The B5-Lite hardware is made from stainless steel, including the hose clamp and ground screw.

The B11 hardware is made from stainless steel.

Mimosa Backhaul Help Content Mimosa Backhaul Specifications

Gasket Materials

Product Applicability: B5/B5c, B11

The orange gasket on the B5c is made from non-latex silicone rubber with Shore A 40 durometer. It was specifically

selected to seal the case without causing deformation between the polymeric and metal portions of the enclosure.

Silicone rubber has excellent weatherability properties and better resists fungus, chemicals, ozone, and UV than

natural rubber compounds.

The black gaskets inside the IP67 gland are made of EPDM (also a synthetic rubber). EPDM also has excellent

weatherability characteristics, and is commonly used in weather seals and roofing membranes.

Indoor Test Methods

Product Applicability: B5/B5c, B5-Lite

Mimosa recommends confirming Backhaul link connectivity on a test bench before field deployment. This ensures

that each device is in good working order and is properly configured.

Tips for Testing B5 and B5-Lite

The B5 and B5-Lite have fixed antenna gains designed to amplify weak signals in an outdoor environment. While

both radios are indoors, the amplitudes of these signals are much greater, and can saturate the receivers. This can

prevent link connectivity, cause loss of link connectivity, or even damage the receivers. To prevent this from

happening, reduce Tx power on the AP to the lowest setting (-7 dBm for B5; 10 dBm for B5-Lite), and turn the

antennas away from each other. Turning the antennas toward the ceiling, depending on multipath propagation,

usually works best.

Tips for Testing B5c

Although the B5c was designed for use with external antennas, two B5c radios will link without an antenna if placed

immediately next to each other on a work bench. A small amount of RF leakage allows for this to happen, although

the link performance will not represent the outdoor performance, so this method should not be relied upon for

throughput testing.

Alternately, B5c radios can be wired for a conducted test, as shown in the photo below, with short jumper cables, 50

Ohm attenuators and coaxial cable adapters. This configuration better represents outdoor performance, but can

introduce noise depending on the quality of the components between the radios.

Warning: Never connect two B5c radios directly without attenuators. This can damage the receivers and

will void the warranty.

Backhaul RF Tuning Process

The Mimosa Backhaul user interface contains a set of tools for selecting channels and adjusting RF parameters. This

document describes how to use each of these to efficiently tune an RF link for optimal performance.

Within this process, it is assumed that the link performance has been modeled and verified using the Mimosa Design

application, and that the antennas have been pointed properly to maximize Rx signal strength using the Aiming

Mode. These are important prerequisites to the RF tuning process that should not be skipped.

Please follow these steps to tune a link for optimal performance:

Use the Site Survey to learn what other devices are detected in the area.1.

Use the Spectrum Analyzer to identify frequencies with the least amount of interference.2.

Use the Channel & Power page to adjust channels, channel width, Tx power and antenna gain (if applicable).3.

Use the Performance Graph to verify that PER is less than 2% on average.4.

Use the MIMO Status Tables to verify that the SNR and MCS support your throughput requirements.5.

Repeat steps 2-5 as necessary.6.

Site Survey

Perform a Site Survey to identify the 802.11 mode, frequency, channel width and signal strength of all AP’s that you

radio detects. Knowing what other devices and device types are in the immediate proximity is important for

collocation of multiple radios, as well as selecting an appropriate channel. More information

Spectrum Analyzer

The next step is to select a channel with the least amount of interference. This is important because throughput

absolutely depends on the signal to noise ratio (SNR). The Spectrum Analyzer can be accessed from either the

Dashboard or by clicking on the Channel & Power page. It actively scans the 5 GHz band to report on interference

sources that may impact link performance by frequency, amplitude, and probability of recurrence. Note that the

Spectrum Analyzer is one of several tools used to measure RF performance, and that you can not depend on it

solely for optimal channel selection. More information

Channel & Power

Since performance depends on maximizing the signal to noise ratio (SNR), use the following settings to target > 30

dB SNR per chain for maximum performance. This table summarizes the SNR required for each MCS.

Channel Settings

Start with a single 20 MHz channel, and then increase channel width and/or number of channels if SNR allows. A

single channel has higher spectral density than two channels. Narrower channels (e.g. 20 MHz) have higher spectral

density than wider channels (e.g. 80 MHz).

Tx Power Settings

The Maximum transmit power is limited by several factors including the number of channels and the selected

channel. Your regulatory domain may limit the maximum EIRP for certain frequency ranges. On very short links,

decrease Tx power to avoid saturating the receiver.

Antenna Gain Settings

Antenna Gain is fixed on B5 and B5-Lite backhaul radios, so no antenna gain entry field is shown. However, Antenna

Gain is configurable on the B5c because it can be paired with antennas which have various gain values. The

Antenna Gain value is used for two purposes:

To limit the maximum Tx power for each channel based on regulatory domain rules in your country.1.

To calculate the Rx Signal target on the Dashboard. The target will be incorrect if the gain value is inaccurate.2.

Dashboard

Performance Graphs

The Dashboard Performance panel contains two graphs (IP Throughput and PHY PER) that can each be selected by

clicking on the circles at the bottom of the graph. Verify that the PER is below 2% on average after association. More

information

MIMO Status

The Dashboard MIMO Status tables show the SNR per chain and the MCS per stream. If the SNR is low for a

particular channel, try changing channels or move to a smaller channel width. Note that PER and SNR are inversely

proportional. More information

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)2.

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 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 priveleges. The password can be changed within the Preferences > General > Set Password

panel of the GUI.

If you are looking for the Mimosa Cloud Log In process, please see Manage User Guide: Logging In.

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.

Else, the menu contracts to provide more workspace within the GUI. Note that the 2.4 GHz Console menu item is not

present on the B5-Lite.

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, GPS signal quality*, 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. On other panels, detailed help text can be found by clicking on the

information icon in the upper right hand corner.

* Applies to B5/B5c and B11 only; does not apply to B5-Lite.
