OTA-XRH-SG-V1

OTA eXtended Reality Head Base Simulating Gel filled Phantom V1

Lightweight homogeneous anthropomorphic head base phantom filled with a broadband head tissue simulating gel for OTA evaluation and optimization of extended reality (XR) head worn devices.

In order to form a complete head phantom for OTA testing, it needs to combined with a pair of anatomical ears:

OTA-EAR-XRH-V1

mmW-OTA-EAR-XRH-V1

Assessment of radiation pattern or total radiated power of eXtended Reality (XR) head worn devices. Needs to be combined with carbon loaded silicone anatomical ears in order to form a complete head phantom for XR device testing.

Compliance with CTIA Certification Standard “Test Plan for Wireless Device Over-the-Air Performance” under evaluation 

Based on SAM data as defined by IEEE SCC34 and 3GPP TR25.914 "Measurements of Radio Performances for UMTS Terminals in Speech Mode" Release 6 and optimized in terms of head and nose breadth in order to better fit head worn devices.
