It realizes functions such as wireless Internet access, mobile phone and computer file sharing, and multimedia playback. It supports different series of WiFi, such as 802.11b/g/n/ac, etc., to meet different wireless communication needs.

VLG 3-in-1 antenna application areas

The design of a 3-in-1 antenna usually needs to take into account the operating frequencies and characteristics of different wireless technologies to ensure that each function can work effectively. For example, 4G communication may operate in a wide frequency band, while GPS signals are concentrated in a specific L-band. WIFI signals cover multiple frequency bands such as 2.4GHz and 5GHz. Therefore, the 3-in-1 antenna needs to be able to provide good performance on these different frequencies.

In practical applications, the three-in-one antenna can provide stable network connection, accurate positioning services and high-speed data transmission capabilities. For example, the three-in-one antenna in the vehicle-mounted TBOX device can support the vehicle's network communication, GPS positioning and in-vehicle WIFI hotspot sharing, thereby improving the level of intelligent vehicle management.
