Sub-GHz development tools are hardware and software tools used to aid in the development and debugging of sub-GHz radio devices. Sub-GHz tools provide access to a low-frequency radio spectrum that is not accessible by conventional tools like Wi-Fi and cellular. They allow developers to more effectively create, deploy, and debug sub-GHz devices in various different application scenarios. Common sub-GHz development tools include signal generators, spectrum analyzers, protocol analyzers, signal emulation systems, channel simulators, and application processors. By leveraging these tools, developers can optimize their sub-GHz devices to maximize performance while complying with regulatory requirements.
