This object reports the operating frequency, in MHz, that the device's second radio is currently using. An admin managing a dual-radio mesh uses this alongside ciscoUrwbFreq1 to confirm the two radios are properly separated in frequency to avoid self-interference between the unit's own links. If ciscoUrwbFreq2 turns out identical to ciscoUrwbFreq1 on the same device, the admin would flag that as a likely misconfiguration causing internal radio interference.
