The Internet of Things (IoT) is about interconnecting physical objects through information transmission devices over agreed protocols. IoT enables objects to communicate and exchange data via information transmission media, achieving intelligent functions such as identification, positioning, tracking, and monitoring. IoT technology has a broad range of applications spanning intelligent transportation, environmental protection, government operations, public safety, home security, smart firefighting, industrial monitoring, elderly care, personal health management, plant cultivation, water system surveillance, food traceability, reconnaissance, and intelligence gathering. Signal transmission in IoT systems typically relies on wireless communication using license-free industrial, scientific, and medical (ISM) bands, which feature low power and narrow bandwidths. Many implementations also adopt technologies such as ad hoc networking and relay transmission.
There are many standards for the Internet of Things. According to the requirements of different data rates, power consumption and mobility, various national organizations, industry associations and industry alliances will define their own standards, especially wireless interfaces. The test of receiver, such as receiving sensitivity, dynamic range, anti-interference ability, etc., is an important RF test item. Siglent’s SigIQPro signal generation software can support the following formats, and cooperate with SSG5000X-V series vector signal source or SDG7000 series arbitrary wave generator to generate various IoT signals for the test of receiver and module.
