6G Terahertz Showdown: Samsung’s 140 GHz Testbed vs. Qualcomm’s 6G Foundry in the 0.3 THz Race

The wireless industry is hurtling toward the 6G era, where data may transmit at terahertz frequencies with fiber-optic-like speeds. In labs across the globe, engineers are already experimenting in bands far above today’s 5G frequencies – from Samsung’s 140 GHz testbed pushing multi-gigabit links news.samsung.com, to Qualcomm’s 6G Foundry initiative rethinking networks from AI to spectrum use fierce-network.com. Even other industry players, like LG and NTT DoCoMo, have demonstrated 0.3 THz-range wireless links that hint at ultra-fast 100 Gbps data rates wca.org. This report dives into each of these efforts – the recent breakthroughs, the frequency bands and use cases they target, and what these early 6G demos mean for consumers and mobile infrastructure as we race toward 2030 for 6G’s debut.
