Wireless 2.4 & 5.2

i was thinking about installing 5.8 Ghz for better internet connection,
can they fit together next to each others? can i have multiple network, 2.4 & 5.GHz? m i going to face any problems?
Thank you!

need to leave enough space between the spokes working in the same band, that is not self-interference between them, if you use several mini-pci in the same routerboard (such as RB433), try not to be of the same band, bone in a mini-pci 2.4Ghz and one in 5Ghz and never the same band.
although attempts to spend a little metal boxes used to house the routerboard, this will help with the external interference that may be on the site.

i’m going to install a new device to broadcast the new 5.8Ghz band.
