The UXM 5G Wireless Test Platform, developed by Keysight Technologies, Inc., is said to help prototype and develop 5G chipsets and devices while keeping up with […]
Gigabit LTE and cellular IoT testing functions augment base station simulator
Software options for the Anritsu Signalling Tester MD8430A expand the LTE-Advanced Pro (LTE-A Pro) testing functions of the base station simulator. With the new software options, the MD8430A supports Gigabit LTE and Cellular IoT scenarios to create a comprehensive test solution that can efficiently verify LTE-A Pro-compliant chipsets and wireless devices. The new functions let […]
Basics of measuring antenna properties
An antenna is simply a conductor or conductor array, usually metal. But how it is situated and terminated that determines its behavior in transmitting and/or receiving electromagnetic radiation. Let’s start with an antenna that is configured to transmit. An oscillating voltage applied at a terminal will cause current to flow through the antenna. A transmitting […]

LTE-Advanced RF conformance test system verifies IoT devices according to global standards
Anritsu Co. says it is the first test company to earn GCF approval for more than 80% of Cat-M1 RF conformance test cases for frequencies used in Japan, North America, and Europe. The test cases can be integrated into the LTE-Advanced RF Conformance Test System ME7873LA. The Cat-M1 RF conformance test cases are software tools […]
Proof-of-parameter test leads experts to formally request NB-IoT standard revision for transceivers
While designing a narrowband internet of things (NB-IoT) terminal transceiver, experts from Hong Kong Applied Science and Technology Research Institute (ASTRI) discovered an improper definition in the NB-IoT standard’s receiver wideband intermodulation requirement. The requirement was more stringently specified than that in the LTE standard, which runs counter to the promise of offering low-cost/low-power NB-IoT […]
