How many dB can a sub-3ghz base station antenna isolate?
According to Huawei antenna test results, when d equals 0.1 m, an isolation greater than 23 dB between Sub-3GHz base station antennas and C-band NR antennas can be achieved.
Is there a standard for a base station antenna?
The BSA’s influence on coverage, capacity, and QoS is extensive, and yet there exists no comprehensive, global, standard focusing on the base station antenna. The purpose of this whitepaper is to address this gap. In particular, the following topics will be covered in various degrees of detail:
What is the operating environment of a base station antenna?
The operating environment of base station antennas is classified as remote, stationary, outdoor, uncontrolled and not weather-protected. The electromagnetic environment includes close proximity to intentionally radiating devices and installation on structures prone to lightning strikes.
What are the requirements for blocking a base station in co-siting?
To prevent blocking interference, 3GPP TS 36.104 proposes the following requirements in the case of out-of-band blocking of a base station in co-siting scenarios: Assume that there is 30 dB isolation between the transmitter and the receiver, the requirements in the following table must be met.
Why do we need additional base stations?
Hence, additional base stations (BSs) may be needed to satisfy the new demand. This case addresses the application of dynamic permanent demand for service such as establishing a new residential area over several time periods where new demand clusters are created in each time period as the residential area expands.
How does a base station receiver work?
A base station receiver (such as the TDD receiver in the following figure) uses RF RX filters (pre-filter and RF-filter) to reject signals outside of the frequency band of the wanted RX signals. This protects the receiver from being interfered by noise and other external blocking signals.
