The Channel Width. width-2 refers to 2MHz, width-3 refers to 3MHz width-4 refers to 4MHz, width-5 refers to 5MHz,width-6 refers to 6MHz width-7 refers to 7MHz, width-1-75 refers to 1.75MHz, width-3-5 refers to 3.5MHz Channel Width depends on Frequency Band. The valid range is as follows: 3.5 GHz (ETSI) should allow channel width 3.5, 7; the rest of bands should allow channel width 2,3, 4, 5 and 6 The Channel Width, Frame size, Downstream/Upstream ratio and cell radius are dependent on each other and the following restrictions should be taken into account when configuring the system: Low Latency Mode Channel Width = 1.75, 2, 3, 3.5 or 4 Not supported Channel Width = 5, distance must be <= 30km Percentage downstream bandwidth must be >= 50 Channel Width = 6 or 7, distance must be <= 40km Percentage downstream bandwidth must be >= 50

Normal Mode Channel Width = 1.75 Not supported Channel Width = 2, if DS/US is 50/50 then distance must be <100km Channel Width = 2, if DS/US is 60/40 then distance must be <90km Channel Width = 2, if DS/US is 70/30 then distance must be <50km

Channel Width = 3, if DS/US is 50/50 then distance must be <100km Channel Width = 3, if DS/US is 60/40 then distance must be <100km Channel Width = 3, if DS/US is 70/30 then distance must be <90km

Channel Width = 3.5, 4,5, 6 and 7, DS/US must be >= 50

Note: It is required to upload the configuration and then reboot the device for the changes to take effect.
