This mystifies me. In the article I referred to, the 
Wikipedia article about "gravitational waves", it says:

"In principle, gravitational waves could exist at any 
frequency. However, very low frequency waves would be 
impossible to detect and there is no credible source for 
detectable waves of very high frequency. Stephen Hawking 
and Werner Israel list different frequency bands for 
gravitational waves that could plausibly be detected, 
ranging from 10E-7 Hz up to 10E+11 Hz." This is referenced.

So I don't know where you get your 10E-16 Hz value from. 
That's a billion times lower than the above quoted lower 
limit.

The frequency of a gravitational wave, of course, would be 
equal to the frequency of quadrupole oscillation of the 
source, whatever that might be.
