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 »

Prepare your Spectrum for 5G Deployment

The rollout of 5G NR will initiate a worldwide deployment in an unknown radio environment where unwanted transmitters can degrade end-user QoE and in some cases cause outages of critical services. Prior to deployment, operators need to ensure the radio environment is free from interference by conducting spectral clearance and interference hunting. This webinar defines… Read more »

Wireless Interference: Measurements, Common Problems, & Solutions

Finding interference, making the measurement and interpreting the results, are key to successful RF interference hunting. Finding offending signals takes time, patience, and knowledge. It is important to use the right measurement tools to get fast and accurate results. And in many cases, identifying and resolving an interference problem, can have both a technical and… Read more »

Interference Hunting in 5G Networks

The tools and techniques used in interference hunting have remained largely the same across previous generations of cellular technologies. Differences in modulation, bandwidth, and frequency bands for 5G networks will however require substantial changes in how interference is detected, located, and resolved in 5G networks. This webinar will provide a short overview of pre-5G interference… Read more »
