Hedge 298: The 6G Hype Begins

The rollout of 5G was framed as a technological arms race, with carriers and governments touting breakthroughs such as network slicing, massive beamforming, ultra‑low latency, and ubiquitous small‑cell deployment. Those promises were used to justify massive spectrum auctions and to rally public support for higher fees. In reality, the three major equipment vendors produced largely interchangeable gear, and the imagined China‑versus‑US race never materialized beyond marketing soundbites. Consequently, many of the headline features—dynamic spectrum sharing, true gigabit‑per‑second mobile speeds, and remote‑surgery capability—remained aspirational rather than operational.

Despite the hype, carriers did deliver noticeably faster downlink speeds, with some markets jumping from 115 Mbps to over 380 Mbps after spectrum refarming. Upload capacity, however, stayed at a meager three percent of total bandwidth, limiting two‑way applications like real‑time gaming or industrial control. Small‑cell rollouts fell far short of the promised millions; only a few hundred thousand were installed, mostly as indoor repeaters rather than true neighborhood nodes. The anticipated surge in private‑5G networks, IoT subscriptions, and premium‑speed add‑ons never materialized, leading to executive shake‑ups and a pivot toward Fixed Wireless Access as the primary commercial use case.

The same narrative is now resurfacing around 6G, with recent White House briefings declaring a new US‑China race. Early 6G discussions echo 5G’s grand promises—terahertz‑band speeds, pervasive AI integration, and satellite‑backed connectivity—while overlooking the economic lessons of the previous generation. Low‑Earth‑Orbit constellations have already demonstrated viable beamforming for Fixed Wireless Access, threatening to eclipse terrestrial 6G deployments. Industry observers caution that without realistic business models and measurable performance milestones, 6G hype may repeat 5G’s pattern of overpromising and underdelivering, leaving investors and regulators wary of another costly rollout.
