Smart Wi-Fi Antennas Reduce Co-Channel Interference
When there are multiple Wi-Fi access points (APs) in the same wireless channel, they interfere with each other, reducing performance. Today's next-gen 802.11ac APs have fewer channels, which means more APs need to use the same channel. And this means more co-channel interference. With the next generation technology that we know is coming in the foreseeable future, there … [Read more...]
