Also known as Radio Frequency, is a radio wave with long-distance transmission capability. It is part of our life in today’s connected world. Whether it is your TV, mobile devices, smart headphones, wearables and other devices, all use Radio Frequency (RF) waves to communicate. Bluetooth, Wi-Fi, Zigbee ,4G (including LTE-M and LTE -NB) and 5G communication technologies, as well as LoRa that are frequently used in IoT products, etc. are areas of RF applications.
The regulatory compliance testing ensures that radio and telecommunication equipment is using the radio spectrum effectively by not interfering with other users. Additionally, the products need to be tested for the electrical safety and RF exposure.
For cellular technologies such LTE-M, LTE-NB or LTA CAT 1, US based MNOs (Mobile Network Operators) have very stringent requirements for the deployment of the wireless devices to use their network. This requires careful selection of RF modules, antenna design and Testing.
RF or Wireless Performance Tests are performed to ensure your product comply with the design specifications and performs well in real world scenarios.
