All the advantages of the powerful functions, high accuracy, fast speed, compact size, easy to install/reassemble/ relocate, make RayZone2800 the best choice for a mobile phone OTA test system.

Certified Accuracy

Quiet Zone (QZ): 42 cm Reflection in QZ: ?-32dB Uncertainty by Chamber: ?0.1dB

Frequency 700MHz 1GHz 3GHz 5GHz 10GHz 15GHz 24GHz
Reflection -42 dB –45 dB –50 dB –55 dB –55 dB 55 dB –55 dB

 

MIMO OTA test urges a lower reflection within the Quiet Zone (QZ) in an anechoic chamber than SISO, which presents a sizable challenge for chamber design, especially with the target size being small enough to fit in an ordinary office. A SISO chamber with a measurement 0.6 SSD* can pass the CTIA certification, but it is not good enough for MIMO. For example, a reflection larger than -30dB in QZ would meet the requirement of SSD to be 0.6, but this reflection could cause 0.6dB errors in MIMO OTA test, which is too big to be accepted.

Utilizing system level simulations, custom- designed high performance absorbers, narrow beam probe antennas, and 3D distributed multi-probe antennas, the reflection in the QZ of RayZone2800 reaches -32dB across all the frequency band, which ensures a small measurement error caused by the chamber.

The size of RayZone2800 is 3m×3m× 2.9m and QZ is 42cm in diameter, which makes RayZone2800 the smallest chamber for the 3D MIMO OTA test system with a certified level of accuracy.

2×2 & 4×4 MIMO OTA Test Under 2D/3D Channel Model

Unique Function, Fastest, Compact

RayZone2800 supports all mobile standards, Wi-Fi, GPS, especially MIMO OTA throughput measurements. With 11 dual polarization probe antennas distributed on a spherical surface, the system perfectly implements Radiated Two-Stage (RTS*) method to measure 2×2 & 4×4 MIMO data throughput under both 2D and 3D channel models. Through this unique advantage, RayZone2800 provides cellphone and antenna companies with a powerful, cost effective test solution necessary to develop high performance products.

GTS has devoted many years of time to fundamental research on RTS, including algorithm, software and hardware implementations. Achievements include fast measurement algorithms, methods to eliminate the effect of reporting uncertainty, implementations of 4×4 inverse matrix, minimizing errors caused by the chamber and probes, minimizing chamber size while maintaining a big enough QZ, and etc. With all these achievements, RayZone2800 is recognized as the best MIMO OTA solution.

RayZone 2800 is a state of the art MIMO OTA solution compact size, great efficiency and high accuracy. By using electromagnetism simulation and optimization design. RayZone 2800's quiet zone can reach 420mm wide and reflective level can be less that 25dB. It can measure both main lobe and minor lobe accurately. RayZone 2800 adopts modular hardware structure and special light material, so it can be assembled on site within a very short construction period.

20 Times Faster 3D MIMO

Fast & Accurate

Mobile phone companies want to improve the data throughput of mobile terminals which is related to user experiences. The standard MIMO OTA test system like MPAC is considered to be slow, high cost, and too large to fit in office buildings, and MIMO OTA measurement under full 3D channel models is even impracticable.

With the patented technology, GTS provides 20 times faster 3D MIMO OTA test solution without the expenses of accuracy. RayZone2800 brings customers much higher efficiency and cost-saving benefits. The MIMO OTA test will no longer be a big headache for the R&D teams to meet their deadlines.

Compact

Easy to Install, Relocated

RayZone2800 is designed to fit in ordinary office spaces. It can be easily assembled by light building modules, and it is also easy to be reassembled when the customer wants to relocate the test facility.

Locate Problems by Measurement

R&D Assistant

For engineers, the final test results, such as TRP/TIS/throughput, is not sufficient to identify problems during mobile phone R&D. They would also like to know the performances of each related parts in order to improve the capabilities of the whole device under development.

A few factors affect the MIMO throughput, for instance, the chipset, number of antennas, performance of each antenna, balance between antennas, envelope correlation coefficient (ECC), sensitivity of each receiver.

RayZone2800 provides the full functions for testing parameters of each part mentioned above. With this powerful diagnostic tool, R&D engineers will be able to locate problems by quantitative analyses of each performance related part to improve mobile devices more efficiently.
