No, IMHO. Most broadband operators don't insert firewalls inline in front of their subscribers, and wireless broadband is no different.
The infrastructure itself must be protected via iACLs, the various vendor-specific control-plane protection mechanisms, and so forth, but inserting additional state in the middle of everything doesn't buy anything, and introduces additional constraints and concerns.
