[Application Example] OTA Testing Solutions in IoT

[Application Example] OTA Testing Solution in IoT - Throughput Testing -

The era of IoT (Internet of Things), where various "things" are connected to networks, has arrived, and many electronic devices, machines, and other "things" are connected to networks using wireless communication. As IoT devices (things) diversify, OTA (Over the Air) testing is necessary for evaluating wireless performance. In OTA testing, these "things" must connect wirelessly in a space that is electromagnetically independent, meaning it does not affect the existing wireless environment and is not affected by it (shielded environment). Our company provides a system that combines electronic programmable attenuators and shielded enclosures as an OTA testing solution compatible with various wireless communication standards, including WiFi, Bluetooth, and cellular. 【Product Introduction】 ■ Programmable Attenuator ■ Shielded Enclosure 【System Configuration】 ■ Programmable Attenuator ■ Shielded Enclosure ■ Attenuation Data Creation and Control Software & Trigger BOX ■ Various Antennas ■ Various Cables ● For more details, please download the catalog or contact us.

Evaluation of wireless IP transmission and communication characteristics of client terminal devices.

[Application Example] Preventing interference from surrounding noise, virtualizing communication characteristic evaluation, and stabilizing the measurement environment to ensure reproducibility of test results.

The development of wireless communication devices such as smartphones (mobile devices) and functional evaluation tests at the time of shipment greatly benefit from the use of electrical attenuators for assessing communication characteristics based on distance attenuation. Our high-speed programmable attenuator MAT series does not produce spike noise during attenuation level switching, allowing for uninterrupted virtualization of the mobile terminal's actual movement. By adopting a programmable attenuator, it is also possible to control it externally via GPIB or similar interfaces. This is particularly effective for creating unmanned testing environments and can be utilized for long-duration durability tests. Additionally, when installing wireless devices inside a radio anechoic chamber, they can be secured with specially developed fixtures for that specific test. By fixing the distance between the transmitting antenna and the receiving terminal, we achieve uniformity in the measurement environment, thereby improving the reproducibility of test results. 【Product Introduction】 ■ Radio Anechoic Chamber Taurus Series MY1520 ■ I/F Module ■ High-Speed Programmable Attenuator MAT800 Series ■ Portable Antenna M301–M309 *For more details, please refer to the PDF materials or feel free to contact us.
