You can use Enterprise Mesh solution, where you have a Root access point that bridges between the Wired and Wireless network and then MAP access points that only require a source of external power.
The APs will use the 5Ghz (802.11a) radio band for network traffic and use the 2.4Ghz radio for client access.
This does require an additional enterprise MESH licence for use with the 1130 and 1242 APs
