In the densely populated cities of East Asia, network densification became a priority for mobile operators before it became critical for U.S. operators. South Korea’s SOLiD, parent of Texas-based SOLiD Americas, is helping its American subsidiary gain experience with indoor deployments that will build a base for 5G densification. Ken Sandfeld, president of SOLiD Americas, said the company is already developing “super hot spots” in Asian markets.
“Super hot spots can deliver 10, 100 Gbps, really a lot of bandwidth to a hot spot location where you technically can use the millimeter wave bands to be able to deliver that high capacity,” Sandfeld said. “Then when you walk away from those high capacity hot spots, then you go back to 4G, which has much better coverage. So I see it really playing out that way for in-building, and we’re only a few years away.”
