Major mobile carriers like T-Mobile and Verizon will soon face critical decisions about developing 6G technology.

Mobile demand is expected to skyrocket to 140–360 GB per line each month by 2040, and 6G will need the spectrum to keep up.
A recent study indicates that the 6G network era will demand three times the currently available mid-band spectrum. Meeting these spectrum demands will foster strong connectivity, advance digital goals, and boost economic growth. John Giusti, Chief Regulatory Officer at GSMA, hopes the report offers valuable insights for governments striving to fulfill their citizens' connectivity needs over the next decade.
The same study highlights the necessity of 6G technology, as new networks bring enhanced capabilities such as:
* Speeds reaching 1 Tbps, around 100 times faster than 5G.
* Latency reduced to under 1 microsecond, compared to 5G's 1 ms.
* Capacity for up to 10 million connected devices per square kilometer.
* Improved global coverage through better satellite integration.
Commercial rollouts are anticipated around 2030, with the US, Europe, Japan, China, South Korea, the GCC region, Vietnam, and India among the early adopters. Projections estimate over 5 billion 6G connections by 2040, alongside billions of 4G and 5G users.
Data demand is also expected to surge, reaching:
* 1,700 EB/month in a low-growth scenario.
* 3,900 EB/month in a high-growth scenario.
This equates to about 140–360 GB per mobile line monthly by 2040. The most intensive users, the top 10% who now account for 60–70% of all traffic, will drive this spike. By 2040, this level of consumption will be typical.
Urban areas, generating 83% of global traffic on just 5% of the land, already strain network limits. Dense urban centers consume nearly 700 times more data than rural areas, emphasizing the importance of mid-band capacity.
The report previews the mobile experience of the 2030s, noting that the benefits of 6G, including speed and low latency, depend on adequate mid-band spectrum.
Without sufficient spectrum allocation, 6G deployment could be hindered by unreliable connections, slow speeds, and persistent urban bottlenecks, similar to current 5G issues.
The study serves as a warning for major US carriers like T-Mobile, Verizon, and AT&T, indicating they will need 2–3 times more mid-band spectrum to handle anticipated traffic increases between 2035 and 2040.
Carriers that proactively prepare, such as T-Mobile, will be best positioned to deliver a true 6G experience. This involves advocating for spectrum allocation, developing long-term network plans, and strategically managing their existing spectrum holdings.
Early preparation will give companies an advantage in the next phase of wireless technology, impacting consumer choices based on dependable coverage. Carriers planning for 6G early are most likely to provide this dependability.
