What General Test Systems does
General Test Systems (深圳市通用测试系统有限公司) is a privately held Shenzhen-based instrumentation company founded in 2012 by Dr. YiHong Qi that designs and manufactures end-to-end Over-the-Air (OTA) test systems for wireless devices, automotive antennas, radar modules, and AIP (Antenna-in-Package) chips across the full product lifecycle. Its core technology stack comprises four complementary measurement modalities — Radiated Two-Stage (RTS) MIMO OTA, spherical near-field, compact range (CATR), and reverberation chamber — supported by the proprietary Wavex software suite and a vertically integrated fourth-generation EPP absorber material line. The RTS method, co-developed with Keysight Technologies and adopted by both 3GPP (TS 37.544, 2018) and CTIA (4.0.0, 2022) as an international standard, is a defining differentiator that enables MIMO OTA testing in legacy SISO chambers at substantially lower system cost than the multi-probe anechoic chamber (MPAC) alternative.
The company operates a B2B enterprise sales motion with multi-channel distribution spanning direct field sales (headquartered in Shenzhen with R&D branches in Beijing, Chengdu, and Shanghai), North American subsidiary AeroGT, and ecosystem integrations with Keysight Technologies and China Mobile. Revenue is generated through turnkey hardware sales (RayZone, RBW/RayRobo, PinProbe, RP, RC, RayVerse, RSP, RN200, DT14KT product families) bundled with Wavex software licenses and recurring technical services including installation, calibration, training, and after-sales support. The customer base spans mobile terminal OEMs, wireless chipset makers, testing laboratories, automotive OEMs, aerospace and satellite communications integrators, and research institutions, with named customers including China Mobile, CATARC Technology, and Oakland University (NIST-funded).
Operationally, GTS markets itself as a complete solutions provider — 'DUT control, chamber management, instrument collaboration, test software' — rather than a point-product vendor, allowing it to capture the full economic value of certification-grade test installations across R&D, pre-certification, certification, and production-line stages. Recognition includes Chinese government designation as a national-level 'Little Giant' specialized enterprise, consecutive IEEE AP-S industry awards to the chairman in 2024 and 2025, and patent leadership of 198 applied and 126 granted patents as of latest reporting.

General Test Systems competitors and assessment
Company assessmentBroad incumbents
- Keysight Technologies: Global test & measurement leader that co-developed the RTS method with GTS and supplies the network testers/channel emulators (UXM, PXT) that integrate with GTS chambers. Overlaps with GTS in wireless device conformance but addresses a much broader portfolio (oscilloscopes, signal analyzers, network test) with significantly larger scale.
- Rohde & Schwarz: German test & measurement giant offering vector network analyzers, signal generators, and OTA test solutions through its own TS8996 and ATS800 chambers. Competes in the same CTIA/3GPP conformance customer pool as GTS but from a broader T&M portfolio standpoint, with much greater headcount and global service network.
- Anritsu: Japanese test & measurement incumbent providing wireless conformance and OTA test equipment (MT8862C, MS2720T) used by carriers and device makers. Overlaps with GTS in 5G/Wi-Fi terminal test channels and could pair with GTS chambers, but Anritsu does not specialize in chamber design itself.
- LitePoint (Teradyne): Teradyne subsidiary focused on wireless connectivity and cellular production-line test (IQcell, IQxstream), directly comparable to GTS's PinProbe M1 parallel production-line OTA systems in the smartphone/IoT factory test segment.
Direct peers
- Microwave Vision Group (MVG): French-headquartered specialist in antenna measurement and OTA testing, offering multi-probe (StarLab, SG24/SG128), spherical near-field, and CATR systems directly comparable to RayZone and RSP product lines. Most direct head-to-head competitor in passive and active antenna pattern/throughput testing for wireless and aerospace customers.
- ETS-Lindgren: U.S.-based designer and manufacturer of anechoic chambers, absorber materials, and OTA test systems serving automotive, wireless, and aerospace customers. Directly competes with GTS's chamber (RC, DT14KT), absorber (EPP/VPP), and full-vehicle OTA offerings, and is a leading CTIA-recognized chamber provider in North America.
- Bluetest: Sweden-based specialist in reverberation chamber OTA testing (RTS, integrated solutions for 5G FR1/FR2), directly comparable to GTS's RC5000 reverberation chamber systems and an obvious peer in the reverberation-method segment of the OTA market.
- Spirent Communications: U.K./U.S.-headquartered provider of wireless device performance and channel emulation test solutions, including MIMO channel emulators that pair with chamber systems. Spirent's channel emulators and positioning test solutions overlap with the channel-modeling side of GTS's RTS workflow.
Emerging players
- EMITE Ingeniería: Spanish smaller-scale OTA test specialist offering reverberation and multi-probe chamber solutions, with a focus on university and small-test-house customers. Less comprehensive than GTS's portfolio but directly comparable in reverberation MIMO OTA methods.
Others
- Yokogawa Test & Measurement: Japanese measurement and control instrumentation supplier (oscilloscopes, power meters, optical spectrum analyzers) serving industrial and wireless test customers. Adjacent rather than directly competing; relevant as a parallel Asia-headquartered T&M vendor with comparable channels into Japanese device makers.
