WAP with outbound ethernet jack wirk with TMO-G4AR

My t-mobile system uses a TMO-G4AR. I want that to wirelessly work with a WAP that has an outbound Ethernet jack. The Ethernet connection will then feed a Ubiquiti directional system down a hill which is +/- 500 feet. Found a WAP earlier but can't find it now. I think it was a NETGEAR product.
