GPS antennas and BeiDou antennas are part of the larger Global Navigation Satellite System (GNSS) and function to receive signals from satellites orbiting Earth, enabling accurate positioning, navigation, and timing. While “GPS antenna” is a common term, it technically refers to antennas that support the broader GNSS network, which includes GPS, GLONASS, Galileo, and BeiDou.

A Wi-Fi antenna is a component of a Wi-Fi device (like a router or adapter) that transmits and receives radio waves carrying data. These waves allow devices to connect to a wireless network, enabling internet access. Antennas can be either external (like a stick or a panel) or built-in within a device.
