Telecom Fiction: It’s 2045, the last cellular towers have just been turned off, and LEO Satellites are handling all communication
Together with the team from Strand Consult, I have written a free report titled “Telecom Fiction: It’s 2045, the last cellular towers have just been turned off, and LEO Satellites are handling all communication”
It’s 2045, and the last cellular towers have just been turned off. For more than a century, connectivity had been intrinsically tied to the ground, manifested through steel towers rising across cities, antennas mounted on rooftops, fibre buried beneath streets, and an endless sequence of generational upgrades designed to justify the continued expansion of terrestrial infrastructure. That world has not disappeared because demand diminished, but rather because demand ultimately outgrew the structural and economic logic upon which it was built.
In its place, a fundamentally different model has emerged. A dense and carefully orchestrated swarm of Low Earth Orbit satellites now carries the full burden of global mobile communication, delivering connectivity through millions of dynamically allocated and continuously shifting beams that reach directly into ordinary mobile devices. There are no external terminals, no visible changes in user behaviour, and no perceptible transition between technologies. The network itself has not vanished; it has simply moved from the ground into orbit, taking with it the complexity that once defined terrestrial telecom systems.
Before going further, it is important to clarify what sits behind this newsletter and how it relates to the broader body of work from which it is derived. This newsletter should be read as a narrative letter and a teaser to a much more comprehensive and technically detailed report. The underlying report explores, in depth, the system architecture, performance characteristics, and engineering specifications that would be required for Low Earth Orbit satellite constellations to fully replicate and ultimately replace terrestrial mobile networks.
Where the full report is analytical and technical in nature, this newsletter serves a different purpose. It is intended to make the vision tangible, to draw the reader into a possible future, and to frame the magnitude of the transformation before engaging with the detailed system design that underpins it.
The report itself does not attempt to predict that this future will unfold exactly as described, nor does it argue that such an outcome is necessarily the most likely path forward. Instead, it asks a deliberately extreme question: if satellites were to fully replicate and ultimately replace terrestrial mobile infrastructure, what would that actually require? By pushing the scenario to its logical limits, the report establishes an upper bound on what is technically and economically conceivable.
Seen through this lens, the most striking feature of the 2045 scenario is not simply that the towers are gone, but that geography itself has ceased to be the primary constraint on network design. Traditional telecom systems evolved through incremental geographic expansion, with infrastructure deployed tower by tower and market by market, each investment governed by terrain, population density, and expected return. The orbital model breaks this dependency entirely.
A key realization underpinning this shift is that achieving global service does not require uniform coverage of the entire planet. By carefully selecting orbital inclinations, particularly in the mid-latitude bands, a satellite constellation can reach the overwhelming majority of global population and economic activity without incurring the complexity and cost associated with full polar coverage.
However, coverage alone does not define the challenge. The true complexity emerges when demand is considered at a global scale. Unlike terrestrial networks, which evolved in relatively isolated regional layers, the orbital system must accommodate a synchronized and continuously shifting pattern of demand driven by human activity across time zones.
Within this system, the satellite itself becomes something entirely new. No longer a passive relay, it evolves into a fully functional orbital base station, capable of generating thousands of simultaneous beams and dynamically shaping them in response to real-time demand. Operating at relatively low altitudes, these satellites are engineered to deliver indoor-grade performance directly to standard devices.
From the perspective of 2025, such a system remains at the edge of feasibility. The technical challenges are substantial, yet even if these are overcome, broader structural factors will determine the outcome. Spectrum allocation, geopolitical realities, and economic constraints are likely to shape a more fragmented and complex future than the idealized vision suggests.
If this transition were to occur, even in partial form, its implications would extend far beyond technology. The economic foundations of the telecom industry would be fundamentally reshaped as infrastructure moves from the ground into orbit and long-established value chains are disrupted.
This newsletter should therefore be read as an invitation to consider the outer limits of what is possible, rather than as a definitive statement about what will happen. It frames the scale of transformation required to move the network into the sky while acknowledging that the actual path forward is likely to be more nuanced.
The most important takeaway is not whether the towers will disappear entirely, but that their dominance is no longer guaranteed. The center of gravity in connectivity is beginning to shift, and with it, the assumptions that have shaped the telecom industry for decades.
The sky is no longer simply above the network; it is becoming an integral part of it, and perhaps, over time, its primary foundation.
While the 2045 vision is technically coherent, achieving it requires simultaneous breakthroughs across multiple domains. The key obstacles are not isolated issues, but systemic constraints that collectively define how far and how fast this vision can materialize.
- Uplink Physics & Indoor Connectivity
Achieving reliable indoor uplink from standard mobile devices to satellites at ~350 km requires overcoming extreme path loss and penetration losses, pushing link budgets to the edge of physical feasibility. - Power & Thermal Constraints
Supporting thousands of high-throughput beams per satellite implies continuous multi-kilowatt RF transmission and compute loads, creating heat dissipation and power generation challenges far beyond current space systems. - Onboard Compute & System Complexity
Real-time beamforming, scheduling, and partial core network functionality in orbit require orders-of-magnitude advances in space-grade processing, autonomy, and fault tolerance. - Constellation Scale & Operational Orchestration
Coordinating tens of thousands of satellites with seamless handovers, high spatial reuse, and global demand tracking introduces a level of system orchestration that has not yet been demonstrated. - Spectrum, Regulation & Geopolitical Fragmentation
The need for sub-3 GHz spectrum, combined with national regulatory control and likely multi-constellation competition, limits global optimization and reduces achievable economies of scale.
Taken together, these challenges imply that the 2045 vision is less constrained by any single breakthrough and more by the need for synchronized progress across physics, engineering, policy, and economics. In practical terms, this makes a fully unified global system unlikely in its pure form, and instead points toward a more gradual, hybrid evolution where satellite systems increasingly complement, and in selected areas, begin to displace, terrestrial networks.
