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:

●

2 x 80 MHz channels operating at MCS 8 with 4 streams would yield 1560 Mbps (390 Mbps * 4 streams).
