Pardon my ignorance on the topic, but are there any commercially available (enterprise grade) products for Wi-Fi over Coax?

If this is used for “back-haul”, what is the key differentiator between this and MoCa (or similarly Ethernet over Powerline)

Well if you want one difference this won't throw RF hash all over the spectrum like ethernet over powerline does.
