Wi-Fi's long goodbye: Crosstalk

IN TEN YEARS, we won't need Wi-Fi. At least, that's what Azhar Hussain, the CEO of IoT company Hanhaa, told me on a phone call late last year. He thinks the end of Wi-Fi is nigh because he believes that allocating spectrum in smaller chunks will let municipalities, universities, and companies create private 5G cellular networks. The convenience of those networks will impel companies to choose cellular connections over Wi-Fi for their IoT devices.
