The command is used to configure a radio interface. This document describes the command in WANFleX software version with TDMA technology support.


Not all radio interfaces have the same set of parameters and options because it depends on the radio module type and standard. A complete list of parameters available for the specific interface can be displayed by "rf interface ?" command. Radio module type and its features list can be displayed by "rf interface cap" command.

If frequency roaming is enabled, make changes to the roaming profile using "mint profile" command before making changes on the unit.


capDisplays the radio module capabilities including the information on power levels, frequencies etc.
band XXX

Allows choosing the bandwidth for transmission, can be specified as numeric or text values:

  • "double" – 40 MHz.
  • "full" – 20 MHz.
  • "half" – 10 MHz.
  • "quarter" – 5 MHz.

The ability to switch between different bandwidth values is determined by the license. Within the same wireless network, devices must have the same values for this parameter.

grid B G

Allows to create a customized frequency grid within the license restrictions, i.e. to form the list of operating frequencies.

  • "B" the bandwidth for which the frequency grid is formed.
  • "G" – list of sub ranges with the defined frequency step (start frequency–end frequency/step), or a list of comma delimited standalone frequencies.

The resulting frequency grid can be viewed in radio interface properties and used in all cases when the frequency is determined automatically ("roaming", "dfs" and so on).

  • "clear" – restores the default frequency grid supplied in the unit’s license.
freq XXXSets central operating frequency in MHz. Must be equal at the both sides of the link.
bitr XXXThe bit transfer rate in Kbit/s of the radio link. Allowed values are:
  • bandwidth 5 MHz: 3250, 6500, 9750, 13000, 19500, 26000, 29250, 32500 Kbit/s.
  • bandwidth 10 MHz: 6500, 13000, 19500, 26000, 39000, 52000, 58500, 65000 Kbit/s.
  • bandwidth 20 MHz: 13000, 26000, 39000, 52000, 78000, 104000, 117000, 130000 Kbit/s.
  • bandwidth 40 MHz: 30000, 60000, 90000, 120000, 180000, 240000, 270000, 300000 Kbit/s.
txpwr XXXSets the transmitter emitting power in dBm. The acceptable transmit power values can vary depending on the radio module type.
sid XXXNetwork identifier, a arbitrary hexadecimal number in the range of 1H to FFFFFFH. All routers that are supposed to see each other on the same radio link must have the same identifier.
txrt XXXSets the maximum number of repeat requests to be done when sending unicast packets. By default is 10.
txvrt XXXSets the maximum number of repeat requests for data packets (excluding voice packets) in voice mode. By default is 5. The maximum allowed value is 64. Voice mode is turned on automatically when VoIP traffic appears.
[-]dpdEnables/disables digital pre-distortion mode. Allows to improve the signal quality by compensating of distortions that occur in the transmission path.

Enables/disables the BURST protocol support.

The BURST protocol is grouping several short packets with the same destination address on a radio link into larger packets, thus significantly decreases the response time for applications when intensive streams of short packets appears. BURST has influence to a whole radio interface on selected device, but the BURST protocol can only work for destinations where it is also enabled at the other end, and only if MINT protocol is used at both sides. BURST does not affect the operation of other devices in the network.

BURST protocol operation statistic can be viewed by using the "muffer stat" command. Enabled by default.

[-]shortgiEnables/disables the short guard interval mode. Using of this mode allows the device to increase its throughput by reducing the time interval between symbols being transmitted. However, this may significantly increase the intersymbol interference and, thus, cause a higher errors rate. Enabled by default.

extnoise X

Raises / lowers the noise level, allows to reduce the interference influence (in case of level increasement) or to increase the received signa the modulation (in case of level decreasement). Available values are from -16 to 32 dB. By default - 0.
[-]pwrctlEnables/disables Automatic Transmit Power Control (ATPC). When it is enabled the system automatically adjusts device’s output power to the optimal value that is necessary and sufficient to maintain the maximum productivity of the link in the given conditions. Enabled by default.

Only for the InfiLINK Evolution / InfiMAN Evolution families devices. Enables/disables the InfiLINK 2x2 / InfiMAN 2x2 families compatibility mode.

To ensure operation in compatibility mode, configuration changes must be made, which are detaily described in the article: Upgrade from R5000 to Evolution.

mimo|misoAllows to select a signal coding method: MIMO or MISO.


In this mode the device use MISO for transmission of service packets while working on a low modulation. It allows keep the link operation when a transmitter in one the polarizations fails or in case of signal levels imbalance in different streams. To disable this mode use the "-misoctl" parameter.
[-]greenfieldEnables/disables "Greenfield" mode. This mode reduces the transmitted frame size, removing the original (pre-802.11n) field from the header. Allows to increase the performance by 15%, as well as avoid the processing and decoding of noise preambles, which leads to an improvement of signal quality.
stat[1] [qos] [mcs]

Displays the radio module's statistic. For more information about table values see "Examples" subsection.

  • "1" – shows statistic in current moment, if not specified, the statistic is displayed in real time.
  • "qos" – shows priorities statistic.
  • "mcs" – shows modulation statistic.
  • "OPT" – shows statistic of all parameters.
