Why AR5414A B2B required for Industrial Applications?

Industrial grade AR5414A B2B chipset is for applications in the most-demanding environments in the world. It must withstand tremendous temperature, humidity, and ambient air ranges. By contrast, the commercial grade AR5414A is for applications generally placed in a climate-controlled environment that is carefully monitored to ensure optimum performance.

1. In normal temperature range 0 –60°C: the power control accuracy of wifi modules using either AR5414A B2B or AR5414A chipset can be the same precise for a professional company as Unex.

2. At temperature of –15°C, -40°C or +80°C, obvious power control accuracy differences can be found on the test result of AR5415A B2B and AR5414A.

Advanced Applications of DCMA-86, DCMA-86II, and DCMA-86III

1.	Today' s Dual-Concurrent WiFi Architecture
	two independent WiFi modules are used to form independent WiFi connections with 802.11b/g and 802.11a frequencies to avoid interruptions in transmission due to radio interference.
2.	Tomorrow's Multi-Concurrent WiFi Architecture
	Unex raises the bar by providing more than two WiFi modules to enable four independent WiFi connections and increase bandwidth efficiency in 802.11a deployments to better overall network performance.
	2-1.	more than two dual-concurrent AP application: use DCMA-86, DCMA-86II, and DCMA-86III in different APs to replace today's standard 802.11a WiFi modules to minimize radio interference and better overall network performance.
	2-2.	quad-concurrent AP application: use DCMA-86, DCMA-86II, DCMA-86III and a standard 802.11b/g GHz WiFi modules in a quad-concurrent AP to better overall network performance and double secure WiFi connection's reliability than dual-concurrent.
