The examples in the parentheses are meant for the types of wireless
networks, not of radio links. This said I accept your point and will
change the relevant text along the RAN suggestion. Regarding IEEE
802.11, another situation where performance could be a problem is the
presence of high radio frequency interference in the unlicensed 2.4 GHz
band used by 802.11b. But it's arguable if PEPs are viable means for
mitigating the problem in such a situation.

Many thanks for the comment.
