How do engineers design 5G base stations?
Engineers designing 5G base stations must contend with energy use, weight, size, and heat, which impact design decisions. 5G New Radio (NR) uses Multi-User massive-MIMO (MU-MIMO), Integrated Access and Backhaul (IAB), and beamforming with millimeter wave (mmWave) spectrum up to 71 GHz.
How does a 5G base station reduce OPEX?
This technique reduces opex by putting a base station into a “sleep mode,” with only the essentials remaining powered on. Pulse power leverages 5G base stations’ ability to analyze traffic loads. In 4G, radios are always on, even when traffic levels don’t warrant it, such as transmitting reference signals to detect users in the middle of the night.
How will mmWave based 5G affect PA & PSU designs?
Site-selection considerations also are driving changes to the PA and PSU designs. The higher the frequency, the shorter the signals travel, which means mmWave-based 5G will require a much higher density of small cells compared to 4G. Many 5G sites will also need to be close to street level, where people are.
How much power does a PSU need?
This is when the PSU is no longer powering the PA, which is the main power draw, but still needs to power other electronics. The current target for low-load efficiency is about 30 W. Some OEMs would like to see that drop to nearly 10 W.
What are the challenges of embedded PSUs in 5G NR?
PSUs often get sandwiched with other components inside an AAU. Thus, engineers need low-profile components, typically under 22 mm. The challenges and opportunities surrounding embedded PSUs highlight how 5G NR compares to previous wireless technologies.
Why are small cells being deployed on streetlights and utility poles?
Small cells are being deployed on utility poles and streetlights, which have limited space for radios and cables. Meanwhile, there are similar constraints on macro sites operating at traditional sub-6 GHz frequencies. For example, many towers are already jammed with cables where weight also affects wind load and thus antenna capacity.
