OTA (Over The Air) test will simulate the transmission scenario of the wireless signal of the product in the air, and this test method can take into account the internal radiation interference of the product, product structure, antenna factors, RF chip transceiver algorithm, and even human body influence. It is a comprehensive test method to verify the air interface performance of wireless products in free space, which is very close to the actual use scenario of products.
Because it is closer to the actual use scenario of the product, a long time ago, mobile phone products or smart wearable products have made strict requirements on the wireless OTA performance of the product.
With the wireless, intelligent and diversified development of Internet of Things products, as well as the gradual attention to customer experience, some non-mobile phone manufacturers have gradually become more and more demanding of the wireless performance of their products, and have also made some OTA performance requirements for their own products.
