Product Brief
Version V1.0.3
1 Introduction of P301-D module
P301-D is a 2.4/5.8G high-bandwidth wireless data transceiver module, consisting of a wireless transmitter (DEV) module and a wireless receiver (AP) module, based on the principle of TDD, using OFDM and MIMO and other key technologies to improve the utilization of the frequency band while providing longer transmission distance, supporting automatic frequency hopping, with the advantages of long distance, strong anti-interference ability, low latency, etc. As a highly integrated module product, P301-D can be widely used in UAV, security monitor, construction, live TV, special inspection and other fields to meet the demands of quick development application.
Single AP module can wirelessly connect 1 ~ 4 DEV modules; AP module and DEV module can transmit HD video, voice and data in both directions. The bandwidth rate of upstream and downstream can be flexibly configured according to the application scenario.
While module is not transmitting any information, it can automatically discontinue transmission and become standby mode for power saving. The module can detect the controlling signal of ACK message transmitting from remote device and verify whether it shall resend or discontinue transmission.

2 Technical features of P301-D module
- Based on the principle of TDD, key technologies such as OFDM and MIMO are used to improve the frequency band utilization
- Support 64QAM, 16QAM, QPSK, BPSK modulation modes and multiple code rates for autonomous dynamic adjustment
- Support AES encryption and multiple security policies to prevent illegal listening and interception
- Adopt frequency hopping scheme, real-time monitoring of interference and automatic selection of frequency hopping range; automatic and fast frequency change and adjustment of modulation and coding strategy (MCS) according to the current channel interference situation
