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.
Why does 5G cost more than 4G?This percentage will increase significantly with 5G because a gNodeB uses at least twice as much electricity as a 4G base station. The more operators spend on electricity, the more difficult it is to price their 5G services competitively and profitably.
Should a 5G power amplifier be combined with a power amplifier?For 5G, infrastructure OEMs are considering combining the radio, power amplifier and associated signal processing circuits with the passive antenna array in active antenna units (AAU). While AAUs improve performance and simplify installation, they also require the power supply to share a heatsink with the power amplifier for cooling.
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.
What is the difference between 4G and 5G?For example, 4G radios are always on (e.g., transmitting reference signals to detect users), even when traffic levels don’t warrant it, such as in the middle of the night. 5G base stations can analyze traffic patterns and determine periods of low data-traffic, when it may be suitable to shut down into a “sleep mode.
