rfconfig command
Description
CAUTION
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.
Syntax:
NOTE
If frequency roaming is enabled, make changes to the roaming profile using "mint profile" command before making changes on the unit.
Parameters
cap
Displays the radio module capabilities including the information on power levels, frequencies etc.
band XXX
Allows choosing the bandwidth for transmission, can be specified as numerics:
80 MHz.
40 MHz.
20 MHz.
10 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 XXX
Sets central operating frequency in MHz. Must be equal at the both sides of the link.
bitr XXX
The bit transfer rate in Kbit/s of the radio link. Allowed values are:
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.
bandwidth 80 MHz: 65000, 130000, 195000, 260000, 390000, 520000, 585000, 650000, 780000, 866700
txpwr XXX
Sets the transmitter emitting power in dBm. The acceptable transmit power values can vary depending on the radio module type.
sid XXX
Network 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 XXX
Sets the maximum number of repeat requests to be done when sending unicast packets. By default is 10.
txvrt XXX
Sets 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.
[-]dpd
Enables/disables digital pre-distortion mode. Allows to improve the signal quality by compensating of distortions that occur in the transmission path.
[-]burst
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.
[-]shortgi
Enables/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.
[-]pwrctl
Enables/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.
[-]transient
Enables/disables the compatibility mode with previous generation devices.
To ensure operation in compatibility mode, configuration changes must be made in accordance to configuration of previous generation device.
mimo|miso
Allows to select a signal coding method: MIMO or MISO.
[-]misoctl
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.
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.
Examples
Displays the radio module's parameters.
Possible ways of how to set frequency grid are shown in the following example:
Set the bandwidth value 20 on the node which use frequency roaming.
