how to make a wireless connection between macbo...

I have a late 2011 Macbook Pro, model 8,2, i7 processor with 128 GB SSD and 16GB ram, running El Capitan, macOS 10.11.  I'd like to transmit a powerpoint presentation wirelessly to an Epson Powerlite 425W projector, which has HMDMI, USB, Ethernet, VGA and other inputs.  The MBP will be operated in a control booth at the back of the theatre.  The ultra short throw projector will be at the front.   Also, I would like to know if it's possible to project different .ppt slide shows from the one MBP to two different projectors simultaneously.  Anyone have experience doing this?  What worked for you?  Any useful links?  Thanks so much.
