What is over the air testing
OTA testing verifies the wireless performance of a product’s transmitter and receiver. Strong wireless connectivity is crucial for consumers, so manufacturers must ensure their products meet these standards. A reliable wireless device builds brand trust and delivers the value customers expect.
Conducting OTA tests early helps prevent costly design errors. Discovering poor wireless performance after launch can harm the brand’s reputation and lead to expensive recalls. Strong OTA results also support benchmarking. Additionally, major network operators have specific OTA requirements that products must meet. Overall, OTA testing boosts confidence in wireless devices.
Near-field measurements can be converted to far-field equivalent measurements using NF-to-FF conversion. This process uses software and transformation algorithms to calculate far-field characteristics. As a result, it reduces the distance needed for far-field measurements, allowing engineers to reduce the size of test chambers like Faraday cages and RF Shielded Enclosures without losing accuracy. The results closely match those taken directly in the far-field.
