**6G promises 2029 debut, but global telcos remain cold, Jefferies warns**

*Despite global excitement, telecom companies remain cautious about 6G's potential due to past 5G experiences and high costs.*

### Introduction
The telecommunications industry is buzzing with speculation about the next generation of wireless technology. Analysts at Jefferies have projected a commercial launch of 6G networks around 2029, promising speeds up to 100 times faster than today’s 5G and enabling breakthroughs in holographic communication, immersive extended reality, and ubiquitous sensor networks. Yet, while research labs and governments celebrate the vision, many carriers are tempering enthusiasm with a pragmatic view of the challenges ahead.

### Key Developments
Recent milestones fuel the optimism: the International Telecommunication Union (ITU) has begun defining 6G use‑case scenarios, and consortia such as the Next G Alliance and the 6G Flagship program in Europe have released white papers outlining terahertz spectrum utilization, AI‑native network architecture, and energy‑efficient hardware prototypes. In parallel, chipmakers like Qualcomm and Samsung have demonstrated early‑stage terahertz transceivers, and several nations—including South Korea, Japan, and the United States—have earmarked billions for 6G research funding. These advances suggest that the technical foundation is progressing faster than anticipated.

### Industry Analysis
Jefferies cautions that excitement must be weighed against the lingering scars of the 5G rollout. Telcos worldwide still grapple with the
