There are companies that do such setups and they have kits ready to go. If you are trying to DIY this, you may have a bad day.
Looking for advice on event WIFI.
What Verizon cellular hotspots would you recommend for a multi-lan router like the TL-ER5120/Open Mesh AP set-up? Trying to provide free wifi to 50 -100 mobile devices in a remote location for a temporary set-up. Verizon signal is the only strong signal.
Thanks
