What's So Special About Dual-Band Wi-Fi?

Wi-Fi can use both the 2.4 GHz and 5 GHz frequencies.  But all radio frequencies behave differently in different environments, depending upon the presence of things like reflective surfaces and the amount of moisture in the air.  2.4 GHz has greater range, if conditions are right, but the 2.4 GHz airspace is also crowded with things like cordless phones, microwave ovens, Bluetooth and Zigbee.  2.4 GHz only has three non-overlapping channels, while 5GHz offers up to 12, so there is less congestion. And so forth and so on. Neither frequency is the best for every application.
That’s why a dual band Wi-Fi device that can use either 2.4 GHz or 5 GHz Wi-Fi to establish the best wireless connection for the local environment confers great advantages.  When you’re shopping for industrial Wi-Fi, always look for a dual band device.
