NB-IoT: The Need for Scanner Based Testing

NB-IoT, (Narrow Band Internet of Things), also known as Cat NB1, is a standard for connecting “things” to the internet through the cellular network. This is a standard focused on machine to machine communications. The range of applications are vast, with key applications including asset tracking, intrusion detection, utility meter reporting, smart parking areas, and… Read more »

5G Antenna Characterization in the Far-Field

5G mobile devices and base stations will be operating antenna arrays and beam-steering techniques in the millimeter-wave region. The question of the far-field measurement distance is particularly critical for such technologies as a larger over-the-air test range means dynamic range issues and significantly larger cost. The traditionally used formula for the far-field distance aims at… Read more »

Antenna Basics

This white paper describes the basic functionality of antennas. Starting with Hertz’s Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained. A more detailed explanation of the functionality of some selected antenna types concludes this white paper.

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… Read more »

LTE and Bluetooth® in-device coexistence with WLAN

This application note employs preliminary theoretical analysis and demonstrates how the problems of in-device coexistence can be measured. Exemplary, the effects of LTE and Bluetooth® traffic on the WLAN performance of a commercially available smartphone are examined. These examples will also enable the reader to design tests for complementary scenarios.
