You get what you pay for certainly applies in this field.
Most “WiFi systems” that I see installed are overkill. 3-6 Araknis, Pakedge, Luxul, Meraki, whosever waps spread out with not the best of performance, sluggishness.
Replace all of it with 2 Ruckus R510’s and you can try to take the customers smile off of their face. It won’t happen however.
Saying Ruckus is too expensive is comical nowadays. Can be had at many places for way less than msrp.
what I explain above outperforms these other systems, are far cheaper and truly set it and forget it.
