5G Macro Base Stations VS Small Base Stations: Differences in BBU RRU Deployment Strategies and Scenario Adaptation

2025-12-16


In 5G network construction, macro base stations and small cells play complementary roles, and their BBU/RRU deployment strategies differ significantly based on coverage needs and application scenarios.

5G macro base stations are designed for wide-area coverage. They typically deploy centralized BBUs connected to multiple high-power RRUs via optical fiber. This architecture supports long transmission distances, higher output power, and advanced coordination technologies such as Massive MIMO. Macro sites are well suited for suburban areas, highways, and wide urban coverage where stable signal strength and capacity are required.

In contrast, 5G small cells focus on localized capacity enhancement. Their BBU and RRU functions are often integrated or deployed in a distributed manner, reducing hardware size and installation complexity. Small cells operate at lower power and are ideal for indoor environments, dense urban streets, stadiums, and industrial parks where traffic demand is concentrated.

From a deployment perspective, macro base stations prioritize coverage and network stability, while small cells emphasize flexibility and precise capacity offloading. A balanced combination of macro and small-cell BBU/RRU deployments allows operators to achieve optimal coverage, capacity, and cost efficiency in diverse 5G scenarios.
