What are 5G NR base stations?

5G New Radio (NR) base stations, also known as gNBs, are classified into different types based on their deployment scenarios, frequency ranges, and technical requirements. Here’s a detailed technical explanation of the various 5G NR base station types: 1. Classification by Frequency Range

How much bandwidth does a 5G transmitter use?

Even sub–6 GHz 5G transmitters have the potential to use bandwidths of up to 100 MHz, therefore any measuring receiver has to be “flat” across the channel bandwidth while adequately rejecting other signals on adjacent channels. At any reasonable distance from the base station, the signal level is going to be quite small.

What are the 3GPP specifications for 5G NR base stations?

The 3GPP specifications define several classes of 5G NR base stations: Frequency Range: Operates in FR1. Requirements: Conducted requirements at individual antenna connectors. Use Case: Suitable for macro and small cell deployments where the focus is on conducted measurements. Frequency Range: Operates in FR1.

What is 5G NR and FR1?

As standards continue to evolve to include higher frequency ranges and wider channel bandwidths, users face new testing challenges and limitations. 5G NR can operate in frequency range 1 at 410 MHz to 7.125 GHz and frequency range 2 at 24.25 to 52.6 GHz. The lower frequency tests in FR1 are similar to 4G LTE tests.

What is the importance of active antenna systems in 5G networks?

The importance of active antenna systems in 5G networks has significantly changed the installation and maintenance of base stations. Gone are the days of simply measuring transmitter power with an absorption power meter or by using a direct connection via a “sniffer” port in the antenna feed.

How many transceivers does a 5G antenna have?

In total, a 5G antenna may have 128 to 256 individual transceivers. All of them may be integrated with their own radiating elements, making the traditional method of measuring antenna input power impractical. Why EIRP is Important Based upon this antenna design change, the most useful measurement of power is EIRP.
