OMAP Wireless Connectivity A band support
Contents
Working with A band (5Ghz band)[edit]
In order to work with A band follow the steps below:[edit]
- 5GHz band is supported by WL1273 chipset (WL1271 supports only 2.4GHz band)
- Modify the fast clock to work with WL1273 module (fast clock configuration is implemented in kernel)
- Define the regulatory Domain to support A band Domain (for example US)
- Perform Calibration with dual band ini file, to support 2.4GHz band and 5GHz band
Detailed Instructions[edit]
- Supporting fast clock configuration (that requires building the kernel):
- Regulatory Domain
- Calibration – Calibration is a one-time procedure, performed before any WLAN operation. Calibration is performed once after the board assembly, or in case the 1271 connectivity daughtercard or EVM are replaced
Note: for supporting A band use the TQS_D_1.7.ini in the Calibration process (TQS_S_2.6.ini is used for WL1271 chipset)
Verify the port configuration:[edit]
In order to verify that the port support both 2.4Ghz (bg band) and 5Ghz (A band), need to run the command: iw phy0 info
The expected results is that both 2.4Ghz and 5Ghz are supported by the port.
