Understanding Private LTE Network Design for High-demand Smart Meters: A PGE Capacity Study

As utilities modernize their grid infrastructure, the evolution of smart meters and edge computing is dramatically increasing data transmission requirements on Private LTE (P-LTE) networks. This presentation showcases Portland General Electric's (PGE) proactive approach to understanding and preparing for high-demand devices on a potential P-LTE network. Through detailed capacity analysis and RF modeling performed in partnership with CelPlan Technologies, PEG examined how factors like geographical distribution, signal quality, sector loading, and noise interference impact network performance when supporting data-intensive smart meters.

The study reveals critical insights about optimal sector loading, coverage optimization, and network expansion strategies, demonstrating how careful RF planning can support high-demand devices while maintaining network quality. The presentation shares key findings about:
• Impact of device placement and signal quality on sector capacity
• Effects of noise rise on network performance and data rates
• Strategies for optimizing existing sites and planning new ones
• Real-world considerations for balancing coverage, capacity, performance and cost

Whether you're planning a new P-LTE deployment or preparing your existing network for next-generation smart devices, this session provides valuable insights for making informed decisions about network architecture and expansion.
The presentation includes actual coverage maps, capacity calculations, and performance data that will help utilities better understand the practical considerations of designing and scaling P-LTE networks for high-demand applications.
