Network Performance Score

There is a demand for an efficient method of calculating an overall score that reflects the perceived technical performance of a network or one of its subsets, such as a region, a period of time or technology. The method described here considers and weights the key performance indicators (KPI) for a wide range of services… Read more »

Understanding PIM

A subtle, but widespread, cause of interference in radio frequency networks in general, and cellular networks in particular, is something called passive intermodulation, or PIM. This paper explains what PIM is, common sources of PIM, how PIM is identified and tested, and the different ways in which PIM sources can be located in the field.

The Wi-Fi® 6 Revolution is a Wakeup Call for Your Test Strategy

Learn about the new IEEE 802.11ax amendment (Wi-Fi 6) The new IEEE 802.11ax amendment (Wi-Fi 6) intends to improve the WLAN system efficiency, focusing on the throughput per station in dense and outdoor environments. Wi-Fi 6 allows for the first time the scheduled communication of several stations (STA) at the same time, to and from… Read more »

5G Evolution: On the Path to 6G

5G deployments have only recently started, and releases beyond R15 will continue to tap into the tremendous potential of 5G. However, as a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030. 6G could offer high-fidelity holograms, multi-sensory communications, Tera Hertz (THz) communications, and pervasive artificial intelligence. In… Read more »

Comparing CW and low duty cycle passive intermodulation (PIM) measurements

The measurement technique used by a PIM analyzer is CW or low duty cycle. The only traceable device available to independently validate a PIM analyzer’s measurement accuracy in the field is a PIM standard. For this technical discussion, the measurement techniques are explored and explained along with the fact that CW and LDC offer similar… Read more »

Testing passive networks in distributed antenna systems (DAS)

In the last decade, worldwide consumer demand for cellular services has driven network operators to strive for better network coverage and within that coverage footprint, better network capacity. Since more than 80 % of cellular traffic comes from inside a building, in-building coverage, and in-building capacity have become a focus of this effort. In addition,… Read more »

LTE mobile network optimization – a definitive guide

This white paper explains the specific field level and key performance indicators that impact the performance and optimization of an LTE network. In order to have good end-to-end performance, each and every performance indicator needs to be optimized. While a single KPI can affect the user experience in a specific context, true performance management is… Read more »

Radio fundamentals for cellular networks

Cellular technologies have advanced from first generation (1G) analog technologies to advanced high performance fourth generation (4G) and fifth generation (5G) systems in just four decades. Despite the increase in complexity of wireless standards and devices, cellular technologies maintain a set of common principles that form the basis behind the design of cellular systems.
