Latest News and EMITE Releases






carrouselImg For immediate release – EMITE has made another big step forward in 5G OTA testing by releasing a unique fully-automated feed antenna carrousel for standardized 3GPP 38.141 5G gNodeB OTA testing using a 1.8m Compaq Antenna Test Range (CATR) in the EMITE F100 anechoic chamber. The novel antenna carrousel is capable of providing fully automated measurements for the frequency range from 1 to 220 GHz, and for both vertical and horizontal polarizations. With an embedded mmWave hardware module, several antennas are rotated to the CATR focal point position, and when in combination of automated Vector Signal Analyzer (VSA) and Vector Signal Generator (VSG) test algorithms the user saves several days of manual changes. With full support for chapters 6 and 7 of 3GPP TS 38.141, the novel antenna feed carrousel brings automation to un unheard-of level in gNodeB OTA testing. Several RF paths with different signal levels, in combination to mmWave oscillators, switches, amplifiers, multipliers, mixers and combiners, set the pace for world-wide first OTA tests up to 220 GHz with the push of a button. The system is currently in use at two customer sites, leading manufacturers of gNodeB. The EMITE-unique fully-automated Graphic User Interface (GUI) software suite allows testing of all Key Performance Indicators (KPIs) in chapters 6 and 7 of 3GPP TS. 38.521-1/2/3. The novel antenna carrousel can be combined to a barbeque-type DUT positioner, allowing automated loading-unloading of very heavy gNodeBs at the chamber flushed entrance. The automation is also capable of operating overnight without human supervision.
