4.5.4.5.7 DL / UL Ratio
The DL/UL Ratio defines the ratio of transmit (downlink) time to receive (uplink)
time, in percents.
The available values are:
 DL = 75%: UL = 25% (not applicable for 3.x GHz units operating with a 7/14
MHz bandwidth)
 DL = 70%: UL = 30% (applicable only for 3.x GHz units operating with a 7/14
MHz bandwidth)
 DL = 60%: UL = 40%
 DL = 35%: UL = 65%
The default is DL = 60%: UL = 40%.

CAUTION
If due to either restrictions imposed by local regulations or any other reason you cannot use the
entire frequency band supported by the selected Country Code, you should disable the Random
Channel Selection option (see Section 4.5.4.5.9.1) and use the Usable Frequency option to
define the frequencies manually
(see Section 4.7.2.2.2.3).
For example, when using the 5.4 GHz FCC Country Code, you may use either frequencies in the
5470-5600 MHz and 5650-5725 MHz bands (with FCC), or frequencies in the 5725-5850 MHz
band.
