Hello @JE22198 ,
alll the models of the ASR 1000 family are not branch routers but edge routers with high performance and rich features but they are wired only.
In the context where you deploy one ASR 1000 or a pair of ASR 1000 as Internet border routers just to make an example, the wireless is managed using WLC (one or a pair for redundancy) in the internal network.
Hope to help
Giuseppe
