1. Data transmission capability: Bidirectional Beidou has bidirectional communication capability, which can realize bidirectional data transmission, while unidirectional Beidou can only receive signals from Beidou satellites, but cannot conduct bidirectional communication.
2. Positioning accuracy: The positioning accuracy of two-way Beidou is usually high, while that of one-way Beidou is relatively low.
Generally speaking, the two-way Beidou is superior in data transmission and positioning accuracy, while the one-way Beidou is relatively simple. If you need more detailed information, it is recommended to contact Huawei officials directly.
