RayZone® 1800
OTA testing system for wireless terminals that supports 5G MIMO/SISO measurements.
Innovative box structure with cleverly asymmetrical thirteen-sided design.
RayZone® 1800’s innovatively employed the asymmetric 13-sided polygon design. Through the 180 degree transformation of some sampling points, with only 12 test antennas, it provides a minimum angle of 15° sampling step as defined in the CTIA measurement. The asymmetric shape determines the irregular distribution of the test probes which maximizes the measurement distance within a small chamber. In addition, matching the antenna quantity with the antenna spacing helps to avoid the direct reflection and reduce the adjacent coupling between antennas.
RayZone® 1800 achieves the same measurement performance as a large certified chamber in one-fifth of the size.
Low Dispersion Antenna
As one of the key components of the OTA testing system, the low-scattering antenna is used in RayZone® 1800 to ensure the system achieves the best testing accuracy.
The antenna operates at frequencies ranging from 400MHz to 7.5GHz, and features:
- A gain flatness of ±0.25dB for every 100MHz bandwidth across the entire frequency range.
- Optimized antenna feeding to enhance standing wave performance.
- Modular design to ensure consistent antenna performance and easy installation and maintenance.
- Compact size, integrated design with surrounding absorptive foam, achieving low-scattering performance.

Product Accuracy
RayZone® 1800 provides antenna engineers with an accurate testing environment to ensure that small antennas can obtain real and accurate antenna patterns in different orientations in the low-frequency range. The figure below shows the test results of a standard passive antenna inside the RayZone® 1800, which is consistent with the software simulation results.
RayZone® 1800 design has passed rigorous system-level hardware simulation, with every component and detail being carefully crafted. Customized measuring antennas with wideband, low-scattering, and low-cross polarization are adopted. The EPP new-type absorption material is firm, durable, environmentally friendly, moisture-proof, and dust-free. The fully-transparent, customized fixture design can effectively reduce blockage and improve measurement accuracy. It is precisely because of the attention to detail that the testing results of RayZone® 1800 can be compared with those of large far-field testing systems. It not only agrees with the laboratory simulation results but also possesses all the testing functions of expensive and large certification-level dark rooms.
Product Advantages
The RayZone® 1800 is an extremely versatile product within the RayZone® series of general-purpose test analogue electromagnetic environment measurement systems. It is powerful, richly configured, and capable of providing testing accuracy equivalent to that of a large-scale darkroom, as well as superior testing speed and consistency.
Based on a brand-new measurement theory and system design, the RayZone® 1800 employs a unique asymmetric polygon design that cleverly multiplies the RF sampling points of the test item, achieving a perfect balance between small space and full functionality. The RayZone® 1800 fully supports SISO OTA testing and can support radiated two-stage MIMO OTA throughput testing with a pure software upgrade, making it a high-performance and cost-effective RF pre-verification test system that conforms to 4G/5G communication standards.
