3.  Lower installation costs (labour)
 More flexibility, also after commisioning
 Trusted & wordwide accepted standard
 Lot of manufacturers, vendors, etc.
 Optimal price/performance levels
 Active development for diverse use
 Great backwards compatibility
 Investmentment-proof and scalable

Why wireless, why WiFi
(at first glance)?

4. Traditional WiFi setup for
Industrial Laundry

5.  Upto IEE802.11N, 2.4 GHz only
 Maximal power settings, 1 big antenna
 No diversity & multi-antenna MIMO:
 Reflections = RF-noise: more power = more
noise
 Increasing number of 2.4 Ghz WiFi
devices = also more noise
 Increasing number of other wireless
devices (PIR, LED, etc.): even more noise
 1 AP/wireless gateway per client

6. Setup for AC Mesh WiFi
in challenging indoor IoT environments

small / RF-clean environment: bigger and/or noisy area:
2 wired sector AP’s covering addition of wireless connected
all stations (fail-over) AP(‘s) (scalable resilience)

7.  Resilient, self-healing mesh (upgradable)
 Multi-AP, fast roaming: maintenance &
reconfiguration during working hours
 RF reflections are feature, no failure
 Wired AP’s on the edges, wireless
connected AP’s in the middle

Main benefits for
mesh AC-WiFi

8. Unifi AC-Mesh specific features
General:
 Fully automatic mesh features
 Dual frequency (2.4 & 5 GHz)
 High bandwidth for IoT / industrial automation
 Enterprise grade, laundry environment proof
 Excellent price-performance
 Cloud based monitoring & maintenance
Sector antenna:
 45 & 90 degree beam
 Gain 5 GHz = 15 dBi, 2,4 Ghz = 10 dBi
