Anritsu announced a new Uplink Interference measurement to identify interference in 5G and LTE TDD networks
Anritsu Company is announcing enhanced functionality to the Field Master™ spectrum analyzer LTE and 5G measurement options. As the rollout and densification of 5G networks accelerates, degradation of network performance resulting from interference in the TDD uplink is becoming more prominent. The latest Field Master software release provides a dual display of the LTE or 5G Frame structure with automatic placement of gates on the Uplink slots alongside the RF spectrum of the gated time slots.
For 5G networks with a coastal or mountainous terrain, RF downlink transmissions readily become subject to atmospheric tropospheric ducting. Signals can travel hundreds of kilometers, resulting in a time offset relative to the far-end base station. The result is downlink power masking the uplink signals from user equipment. It is also essential that there is a common frame slot format deployed on all operator networks in a country, and ideally at international borders. The new uplink interference measurement includes configurations for the common frame slot formats recommended by international standards organizations, including GSMA, ITU-R, and ECC/CEPT.
