Why should you use external antennas in your Wi-Fi environment? There are many reasons you should use them. In this episode, we talk about what to look for in external antennas, what to watch out for when deploying them, and what details to keep in mind.

We are used to internal antennas from our access points. Have you considered using external antennas to meet your Wi-Fi requirements? In this episode, we provide some educational material around external antennas. Yes, they do add some cost to a project but it’s not much compared to the solution they bring to your Wi-Fi network. There are use cases for external antennas and below are the topics we talk about during the episode.

This episode is proudly sponsored by AccelTex Solutions. They are providing a special offer just for our listeners. If you head over to their products page and use promo code CTS Podcast 72 they will send you a free antenna sample of your choice.
