• Enable/disable wireless link (enabled by default)

• Set the node type to Master or Slave
  • Master: can establish connections with all other types of nodes. It is able to form a network of any topology with other master nodes. A master node is usually used in the configuration of the both sides of the PtP links and in the configuration of the BS for the PtMP links. For master node only, the marker access (polling) can be enabled. Only one master node from a network segment can have this option enabled by means of which it is forming a star-topology segment (PtMP). With this, all other nodes break their connections with their respective neighbors (with exception of connections formed by Join). This node type is usually used for static networks with no (or very small) nomadic or mobile clients.
  • Slave: can only connect to master type nodes (the connection cannot be established between two slave nodes). A slave node is usually used in the configuration of the CPE.

• • Slave: can only connect to master type nodes (the connection cannot be established between two slave nodes). A slave node is usually used in the configuration of the CPE.

Polling

(Master, MINT firmware only)

• Set the polling mode:
  • "Off" - Polling is disabled, CSMA-CA technology is used.
  • "On" - unit operates in "Polling Master" mode.
  • "QoS" - polling operates taking into account the traffic priority for uplink.
• It is strongly recommended to keep Polling on at all times to maximize the link performance
• Polling is especially required for PtMP systems and long haul PtP links.
• Can be enabled on master node only.

MultiBS

(Slave)

• Enabled: when the link parameters deteriorate, the CPE will disconnect from the current base station and try to find the sector with the best parameters values
• Disabled: the CPE will keep the connection with a current base station until the signal is completely lost
• It is available for Slave node only

This setting determines the operating mode of the device. The operating mode is determined by the application of this node in the network.

• Fixed - the node has a fixed position in the network, it is constantly on. It is a core node of the network. Recalculation of the MINT connections cost in this mode will occur every 3 seconds.
• Nomadic - the node can change its geographic location, but data exchange within the network, as a rule, occurs when the node does not move. The cost of MINT connections will be recalculated every 1.5 seconds.
• Mobile - the node often moves. Data exchange take place during the movement. Recalculation of the cost of MINT connections will occur every second.

Polling

(Master)

• Set the polling mode:
  • "Off" - Polling disabled.
  • "On" - unit operates in "Polling Master" mode.
  • "QoS" - polling operates taking into account the traffic priority for uplink.
• It is strongly recommended to keep Polling on at all times to maximize the link performance
• Polling is especially required for PtMP systems and long haul PtP links.
• Can be enabled on master node only.

DFS

(Master)

Radar Detection

(Slave)

• Enable/disable "Radar Detection" features (a special license with the country code is necessary)
• The DFS system performs radar detection and if a radar signal is detected, that frequency is marked as occupied and it can be used again only after a hold-down interval (the link is switched automatically to another frequency)

Max Links

(Master)

• Maximum allowed number of connected CPEs ( in the case of radio connection ) . When this value is reached, other attempts to connect to the base station will be rejected

• Set the output power of the radio interface
• Acts as a top limit for the output power control if the ATPC mechanism is turned on
• By default, it is turned on (it is strongly recommended to remain “on”)
• The offset parameter is used to adjust the thresholds

• Set the name for this node in the network
• By default, it is the "Unknown" node
• This node name will appear on the neighbor lists

• Enable/disable the data scrambling to improve the connection stability (enabled by default)

• Enable/disable gateway for SNMP-traps

• Enable/disable the switch border mode. In this mode the unit operates as a "borderline" between the MINT domains, i.e. prevents the distribution of information about the switch groups and data transfer between these domains, while retaining all the capabilities of the MINT protocol (obtaining information about the whole MINT network, sending remote commands etc.)

• "low" - this option sets the minimal signal level for the neighbor. Signal level is measured in dB above the noise threshold for the current bitrate. If the level gets lower than specified value the connection with a neighbor will be lost.
• "high" - this option sets the minimal SNR for a new neighbor. Signal level is measured in dB above the noise threshold for the current bitrate. If neighbor’s signal level is equal or higher than a specified value the node will consider this neighbor to be a candidate

• The noise level measured by the radio module is calculated as the minimum received signal level (RSSI) in a certain period
• The "RX Attenuation" parameter allows manually raise noise threshold on several dB. In this case the radio module won't react to signals below the established threshold. In certain cases it gives the ability to be protected from the low signals interferences which disrupt the radio module as a result of capture effect. This effect is expressed in the fact that the radio module having captured the low signal from the foreign source, tries to strengthen it and to accept completely ignoring a strong signal from the client which has appeared later
• This parameter allows to protect the receiver from the powerful signal source overload

Multicast Mode

(Master)

• Set the mode:
  • "static" - the unit can establish connections only with units, which MAC-addresses are listed in the "Static Links" section
  • "public" - the unit can establish connections with any other units which have the same security key and the corresponding wireless connection settings
  • "remote" - centralized authentication method suitable for point-to-multipoint connections. It assumes the storage of the end node keys within the MINT network both at the base station and at other nodes directly connected to the base station.

Activate routing using the ODR protocol. The following modes are available:

• "Disable" - routing using ODR is not performed.
• "Hub" - the device acts as a central node.
• "Spoke" - the device acts as a peripheral node.

The main advantage of ODR protocol is a network throughput efficient use. Part of the link throughput is usually used by the routing protocol to transmit service information, this part can be released by ODR using. The ODR protocol transmits the hosts IP prefixes  using the MINT protocol at the data link layer.

The ODR protocol can only be used in networks with star topology, where all nodes are connected to the central node only. An example of such a network is a point-to-multipoint topology, where each subscriber is connected only to a base station.

Automatic updates in the MINT domain may be configured in the following modes:

• “Disabled” - the device does not check if other devices in the MINT domain have a newer software versions.
• "Passive" - in case a newer software version is detected on one of the neighboring nodes, the device requests and updates the software. The device does not announce own software version.
• "Active" - the device announces its software version in the MINT domain, making it available to download by other nodes.

• Set the log level:
  • off
  • normal
  • detailed

• Allows to set fixed cost value to all routes passing through this interface
• The device will select the route with the lower cost, if any

• Allows to add additional cost value to all routes passing through this interface

• Allows to add additional cost value to all routes passing through interfaces that are joined to this interface by the join option

• Activate the failover function on this interface. For more information about this function proceed to the article "Link aggregation, balancing and redundancy"
• If the MAC address of a neighbor is specified, then the device will monitor the availability of this address. If the MAC field remains empty - the neighbor's address will be determined automatically

• Set the bandwidth of the radio interface in MHz
• It must be the same at both ends of the link

• Set the radio interface frequency (in MHz)
• It must be the same at both ends of the link
• If it is set to “Auto”, the Slave node is scanning on all frequencies for the Master nodes

• Set the frequencies that are allowed to be chosen by the DFS mechanism (available only when the DFS system is enabled)

• Note that this option is different from the "Customer Frequency Grid" tool which allows narrowing down the frequency range available in the "Frequency" option from the Radio profile

• Set the maximum operating bitrate of the radio interface (from 13000 to 130000 Kbps)
• Acts as a top limit for the bitrate if the Autobitrate mechanism is turned on
• By default, it is turned on (it is strongly recommended to remains “on”)
• Adjust the Autobitrate system thresholds when the remote SNR doesn’t have the normal level

• The channel type can be set as:

  • Dual: enables MIMO operational mode with different Tx and Rx data streams (recommended)
  • Single: allows to operate as MIMO with duplicate Tx streams, MISO or SISO depending on the Tx/Rx chain configuration (description below)

• Infinet MIMO 2x2 technology effectively doubles the spectrum efficiency and allows to achieve a real throughput up to 280 Mbps in 40 MHz band

• Enable/disable the "Greenfield" mode
• When activated, the "Greenfield" mode increases the link performance by 10-15%, by reducing the packet overhead (optimizes the frames transmitted via the RF link)
• "Greenfield" mode must be enabled at both ends of the link (the wireless link does not establish if "Greenfield" mode is enabled at one end of the link and disabled at the other end of the link)

• Set the network system identifier (up to 8-digit HEX figure)
• It must be the same at both ends of the link

• Set  the device identification number
• The parameter is optional
• Node ID can be configured by the administrator for a better representation of a neighbors table (nodes within a wireless network)

• Set the secret key word for encoding of the protocol messages
• It must be up to 64 characters long, without spaces
• It must be the same at both ends of the link

VBR

(Slave)

• The mode at which the service information is carried out at above a minimum bitrate (if possible)

Radar Detection

(Slave)

• Enable/disable "Radar Detection" features (a special license with the country code is necessary)
• The DFS system performs radar detection and if a radar signal is detected, that frequency is marked as occupied and it can be used again only after a hold-down interval (the link is switched automatically to another frequency)

Max Links

(Master)

• Maximum allowed number of connected CPEs ( in the case of radio connection ) . When this value is reached, other attempts to connect to the base station will be rejected

Use AUX-ODU-SYNC

(Master, TDMA firmware only)

Sync Hold Time

(Master, TDMA firmware only)

• Standalone downtime in case of external synchronization unit disable. Value "0" (zero) disables this parameter control, command to work always is set
• In case of external synchronization unit disable, the devices can synchronously work for some time using own clock signal generator. However, eventually, because of generators frequencies mismatch, the time discrepancy can reach unacceptable values and devices will begin to interfere with each other. In this case, through fixed time the device will stop the transmitter and will stop operation of TDMA until synchronization unit enable

Frame Size

(Master, TDMA firmware only)

• Set the time slot duration (in milliseconds)
  • Consists of transfer time, reception time and guard intervals
  • The range is from 0.5 to 10 ms in increments of 0.1 ms
  • The recommended values for links PtP at the balanced channel depending on channel width: 2-2,5 ms for 40 MHz, 2-4 ms for 20 MHz, 3-5 ms for 10 MHz, >5 ms for 5 MHz
  • The recommended values for links PtMP depending on channel width: 5 ms for 20 and 40 MHz

Auto

(Master, TDMA firmware only)

• This option works only for links "PtP" and allows to reduce the window size and a delay at absence or a small amount of traffic. Automatically selects the frame size

Turbo

(Master, TDMA firmware only)

• Increase the throughput in case of link degradation due to errors in the radio. The sliding window of the ARQ algorithm are extended from three to five frames, which increases its efficiency.

SCS

(Master, TDMA firmware only)

• In case of retries, increase throughput and reduce latency.
• In this mode, ACKs are sent in the same frame as the transmitted data, thus it is most effective in point-to-point mode.

DL/UL ratio (%)

(Master, TDMA firmware only)

• Set the DL percentage of the time slot
  • The range is from 5 to 95% in increments of 1%
  • The empty field enables the mode of flexible DL/UL ratio adjustment depending on traffic load
• Real accepted values depend on the used bandwidth, the frame size and the used modulations. To determine the established value acceptability it is necessary to control parameters (Tx Time Limit/Rx Time Limit) in radio interface statistics. Any of these parameters shall not be less than zero. In the PtMP system with a large number of clients, the ratio of real throughput in this or other way does not match the established DL/UL value. Uplink performance will always be less, because of big overheads of the uplink traffic servicing. In case of a large number of clients value more than 65% practically do not lead to throughput increase in Downlink. Rated speed in Uplink and Downlink (Rx Cap/Tx Cap) is reached only in case of sector full and balanced load by all clients

Max Distance (Km)

(Master, TDMA firmware only)

• Set the maximum operational distance (in kilometers)
  • Has an impact on guard intervals duration
  • The range is from 1 to 100 km in increments of 1 km
• It allows the system to calculate signal propagation time to the furthest subscriber and value of the guard interval between transmission and receiving phases. It is recommended to set 3-5 km more than really measured distance. In case of LOS condition violation or with a large number of reflections larger value as 10-20 km can be required

STA RSSI (dBm)

(Master)

• Set the target power of received radio signal from Slave node at the input of Master node
  • The range is from -90 to -20 dBm in increments of 1

• It allows to reduce the radiation influence from the subscriber units to the neighbor sector due to insufficient suppression of the antenna pattern back lobe

• To achieve maximum TDMA network performance it is important to obtain the highest possible signal level and modulation (bitrates), so transmitter power reducing is a necessary measure. If possible, it is better to try to reduce the impact of clients on neighbor sector (and vice versa), organizational measures (shielding, antennas diversity, etc.)

DFS

(Master)

• Set the output power of the radio interface
• Acts as a top limit for the output power control if the ATPC mechanism is turned on
• By default, it is turned on (it is strongly recommended to remains “on”)
• The offset parameter is used to adjust the thresholds

• Set the name for this node in the network
• By default, it is the "Unknown" node
• This node name will appear on the neighbor lists

• Enable/disable the data scrambling to improve the connection stability (enabled by default)

• Enable/disable gateway for SNMP-traps

• Enable/disable the switch border mode. In this mode the unit operates as a "borderline" between the MINT domains, i.e. prevents the distribution of information about the switch groups and data transfer between these domains, while retaining all the capabilities of the MINT protocol (obtaining information about the whole MINT network, sending remote commands etc.)

• When enabled on the Master, sets it as the global leader node of the MINT network.
• If enable on Slave, device should search and connect only to a network which has one or more global roaming leaders.
• It helps to prevent the creation of locally closed segments that are separated from the main network.
• Any MINT device (including InfiMUX) that has direct access from the control center or has access to the Internet can be assigned as a leader.

• "low" - this option sets the minimal signal level for the neighbor. Signal level is measured in dB above the noise threshold for the current bitrate. If the level gets lower than specified value the connection with a neighbor will be lost.
• "high" - this option sets the minimal SNR for a new neighbor. Signal level is measured in dB above the noise threshold for the current bitrate. If neighbor’s signal level is equal or higher than a specified value the node will consider this neighbor to be a candidate

• "high" - sets the minimal EVM for a new neighbor. Signal quality is measured in dB. If neighbor’s EVM level is equal or higher than a specified value the node will consider this neighbor to be a candidate. Value by defaut is 8.
• "low" - sets the minimal EVM level for the neighbor. Signal quality is measured in dB. If EVM gets lower than specified value the connection with a neighbor will be lost. Value by defaut is 0.

Limits the maximum signal level, preventing devices connection. If the SNR level of an already connected neighbor is exceeded, the connection will be terminated.

• Lockdown – blocks attempts to connect from a device whose signal level has exceeded the limit for a specified time in seconds.

• Per Packet – sets the maximum number of packets retries at which the system lowers the modulation, 9 by default.
• Percent – sets the percentage of retries at which the system lowers the modulation, 7 by default.

• Allows to influence autobitrate mechanism in the following way: it sets upper bitrate index threshold below which errors and retries checks are not performed, just energetic ability to upper bitrate is taken into consideration.
• Bitrate indexes are from 1 to 8 and correspond with bitrates available on the device’s radio interface (bitrate list is available in the "Current settings" part).
• The "0" value cancels the limitation.

• The noise level measured by the radio module is calculated as the minimum received signal level (RSSI) in a certain period
• The "RX Attenuation" parameter allows manually raise noise threshold on several dB. In this case the radio module won't react to signals below the established threshold. In certain cases it gives the ability to be protected from the low signals interferences which disrupt the radio module as a result of capture effect.

  • "remote" - centralized authentication mode with remote server (e.g. RADIUS or relay). In this mode any node can request the information from a remote authentication server (remote authentication server parameters are set using “AAA” command). This means that the node must have an access to this server (e.g. using IP)

Activate routing using the ODR protocol. The following modes are available:
