Product description
Product Overview
● Leveraging OFDM + MIMO and mobile Ad hoc networking technologies, this system operates independently of any existing communication infrastructure, enabling the temporary, dynamic, and rapid establishment of a wireless IP mesh network. It features self-organizing, self-healing capabilities and high resilience, making it well-suited to support the seamless transmission of multimedia services such as data, voice, and video.
● Long transmission range: Utilizing technologies such as OFDM and transmit-receive diversity, line-of-sight communication can reach over 30 km, while maintaining strong anti-interference and diffraction capabilities even in challenging environments.
● High transmission rate: Utilizing technologies such as OFDM, adaptive modulation with BPSK/QPSK/16QAM/64QAM, and receive diversity, it’s ideal for multi-hop transmissions of large data volumes.
● Large network scale: Utilizing the CSMA/CA protocol and dynamically allocating channel resources, the system significantly enhances network coverage as well as the flexibility and adaptability of self-organizing networks.
