As we enter the 5G era, operators will adopt “micro base stations” to achieve comprehensive network coverage. But how can high-end SMT (Surface Mount Technology) assembly lines in the electronics industry effectively integrate with 5G base stations?
The Compact Design of 5G Micro Base Stations
Despite their small size, 5G micro base stations incorporate critical components such as Baseband Unit (BBU), Remote Radio Unit (RRU), and antennas. With the reduction in size, the available space for components has become exceedingly limited. This compactness poses significant design challenges in addition to space constraints, including EMC (Electromagnetic Compatibility) testing and power consumption control.
These challenges are deeply intertwined with power management. If various power components on the circuit boards can be more integrated and miniaturized, it will significantly simplify the design of 5G base stations.
Advanced Technologies in 5G Base Stations
5G base stations leverage cutting-edge technologies such as Massive MIMO (Multiple Input Multiple Output) and advanced coding techniques like LDPC (Low-Density Parity-Check) and Polar codes. These innovations enable extraordinarily high bandwidth, with user experience speeds reaching up to 1 Gbps—100 times faster than 4G—and peak speeds soaring up to 20 Gbps, marking a 200-fold increase compared to 4G.
Beyond high speeds, 5G also offers critical characteristics such as high reliability, low latency, low power consumption, and extensive connectivity. These attributes significantly drive the proliferation of applications in remote healthcare, industrial automation, autonomous driving, smart cities, and smart homes.
