An AP vendor being considered for a WLAN deployment suggests that their 2.4 GHz and 5 GHz dual-band APs use software-defined radios. What unique capability does this indicate in comparison to non-software defined radios?
A.
At least one radio can be configured for either 2.4 GHz or 5 GHz operations
B.
The radios can have their SSIDs configured through software
C.
Software is used to configure the encryption settings
D.
Software is used to configure the entire WLAN profile
Software-defined radios (SDRs) offer flexibility in RF operation. In dual-band APs, an SDR can be programmed to operate on either 2.4 GHz or 5 GHz, allowing dynamic optimization of the spectrum based on demand and interference.
From CWDP-305:
“Software-defined radios can be configured to operate in either band, allowing administrators to shift coverage based on band congestion or capacity requirements.”
This flexibility helps address issues in high-density deployments or when minimizing interference is critical.
