The State of 5G

The State of 5G

With high hopes and skepticism, we set out to survey the wireless ecosystem from manufacturers, operators, test houses, and labs, service and repair specialists, network maintenance and installation professionals, and more to get a thorough status report on 5G. What we discovered was that after years of hype around cutting-edge network technology, gigabit speeds, and…

LTE UE receiver performance measurements

LTE UE receiver performance measurements

LTE user equipment (UE) receiver performance has significant impact to cellular radio network coverage and capacity. It determines the maximum data throughput across the air interface between the LTE base station (eNB, evolved node B) and the mobile network subscriber UE, thus it determines the total capacity across the air interface. Therefore, it is one…

Identifying and Locating Short-Duration Interferers

Identifying and Locating Short-Duration Interferers

The ability to efficiently detect, analyze and locate sources of radio-frequency interference has become increasingly important in modern wireless networks. Unlike constant or near-constant sources, so-called short-duration interferers can only be detected for brief periods of time and therefore special tools and techniques are often required when searching for these types of signals. This paper…
