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 »

dB or not dB?

Everything you ever wanted to know about decibels but were afraid to ask… True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads.… Read more »

Interference hunting in TDD networks

In time division duplex (TDD) networks, the downlink (DL) and uplink (UL) use the same frequency band in different timeslots. When viewing such TDD signals on a conventional spectrum display, it is impossible to differentiate the two as well as any other unwanted signals present in the same spectrum. This makes interference hunting extremely difficult.… Read more »
