Mobile Network Energy Tradeoff

Definition

The mobile network energy tradeoff is the tendency for higher throughput, wider bandwidth, higher-frequency operation, denser coverage, and more antenna elements to increase power demand even as each generation improves other forms of technical efficiency.

Current Synthesis

The source explains 5G energy use as a system effect rather than simply “a stronger signal.” Higher capacity can require more spectrum and processing; higher frequencies can reduce practical range and increase coverage density; multi-antenna systems add active radio elements; and patchy coverage can persist despite a large base-station count. Network sleep and load-aware shutdown can reduce waste, but user mobility and service expectations limit how aggressively infrastructure can be turned off.

Key Claims

• Throughput improvements can raise absolute energy use even when efficiency per transmitted bit improves.
• Higher-frequency propagation and smaller effective cells can increase infrastructure density and coverage complexity.
• Multi-antenna transmission adds performance and capacity while increasing equipment and power demands.
• Load-aware shutdown and renewable power address different parts of the problem: demand reduction versus electricity source.

Evidence

• Capacity evidence: 特番｜从蜂窝网络到手机革命：杨旸谈移动通信浪潮三十年 links wider bandwidth and higher information density to greater network energy use.
• Coverage evidence: 特番｜从蜂窝网络到手机革命：杨旸谈移动通信浪潮三十年 uses Shenzhen’s large 5G deployment to argue that dense infrastructure can still leave coverage holes when effective cell range falls.
• Mitigation evidence: 特番｜从蜂窝网络到手机革命：杨旸谈移动通信浪潮三十年 describes traffic-tide-based base-station shutdown and wake-up, plus wind and solar supply, as network-side responses.

Counterevidence & Qualifications

The source does not separate peak power, annual energy, per-bit efficiency, embodied infrastructure energy, or operator-specific network design. Its frequency examples, base-station counts, and electricity-bill claims are source-scoped and require technical verification before quantitative reuse.
