6 Frequently Asked Questions about “Increase the power supply of mobile base station equipment”
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.
Does mmWave increase power consumption?
In urban and suburban deployments using mmWave and small cells, this efficiency is offset by higher quantity of small cells required, which increases overall power consumption. Is pulse power the solution? Infrastructure OEMs and their suppliers see “pulse power” as a potential solution.
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.
Do AAUs reduce power consumption?
While AAUs improve performance and simplify installation, they also require the power supply to share a heatsink with the power amplifier for cooling. An integrated architecture reduces power consumption, which MTN Consulting estimates currently is about 5% to 6 % of opex.
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.
