With private networks connecting to many IoT devices, testing the device’s user interface requires updating test processes. Many IoT use cases rely on private 5G networks because they offer greater network control, better security, more reliable performance, and dedicated coverage and capacity as opposed to using a public network. With these advantages, private networks play…
Rohde & Schwarz, NVIDIA to demonstrate AI/ML signal processing at MWC 2023
The demonstration uses hardware-in-the-loop and compares a wireless receiver’s signal processing to traditional methods.
Spirent completes Open RAN testing with three functions
The addition of a “wraparound” distributed unit test product for distributed units augments previous test suites for radio units and centralized units. Open radio-access networks (Open RAN) disaggregate a base station’s baseband unit (BBU) — the unit between the antenna and network core — into three parts: Radio unit, RU or O-RU; Distributed unit, DU…
Wireless platform tests 5G RedCap IoT communications

GL Communications Inc. addressed the press regarding their solutions for emulating various telecom protocols (VoIP, TDM, Analog, Wireless) within a single framework – Message Automation and Protocol Simulation. The application includes various test cases to confirm the functionality of telecom infrastructure. GL’s comprehensive Signaling and Traffic Emulation test equipment suite, commonly referred to as Message…
Inject disturbances into power rails with a “cool” probe
The P2124 from Picotest lets you inject modulation signals onto your board’s power rails for noise immunity testing.
An RF playground for automotive design engineers
An automotive test lab in Silicon Valley lets RF engineers test the wireless connectivity of automotive components. In a video interview, Cetecom’s Amber Neves shows the test setup. The connected car. We hear about it constantly. Not only are cars connecting to phones and other consumer devices, they’re also connecting directly to cellular networks. That’s…
Video: Wi-Fi 7 operates across frequency bands
In a video interview, Wi-Fi test veteran Fanny Mlinarsky updates us on Wi-Fi 7’s new features and how they work.
Channel-sounding measurements: Part of active 6G research
Universities and industry engineers strive to understand how sub-THz signal behave in the real world.
How to increase SNR when testing at mmWave frequencies
Communication systems such as 5G that operate at today’s wide bandwidths and high orders of modulation need to maintain proper SNR and EMV. Path loss and phase noise can get in the way.
