DJHW/HZ‑27‑100M‑C is an ultra‑compact airborne MESH ad‑hoc video‑data communication module built on the 2nd‑generation chip platform. Adopting an OFDM flat‑architecture, it achieves low‑latency, long‑range high‑bandwidth wireless transmission. With 2T2R dual‑transceiver design, it supports both MIMO and CA (Carrier Aggregation) working modes. It delivers up to 30 km line‑of‑sight transmission under open air‑ground condition with 200 m elevation difference, and provides 95 Mbps shared network throughput, supporting large‑scale MESH networking of up to 64 nodes.
Measuring 56.0×57.0×14.9 mm and weighing ≤58 g, the unit integrates a temperature‑controlled cooling fan and accepts wide‑range DC 9‑36 V input. It is equipped with dual 100 Mbps Ethernet ports, multiple RS232, TTL serial ports and MMCX RF interfaces. It supports network split‑merge, dynamic intelligent routing, automatic frequency hopping and transmit‑power auto‑adjustment. The embedded WEB‑UI enables network‑topology visualization, SNR / BER monitoring, as well as local and remote OTA firmware upgrade. Optimized for payload‑limited mobile platforms such as UAVs and inspection robots, it realizes integrated backhaul of video, control commands and sensor data for emergency communication, power‑line inspection and offshore monitoring.

DJHW/HZ‑27‑100M‑C belongs to DJADHOC 2nd‑generation MESH ad‑hoc airborne‑module family. Based on OFDM wireless communication technology, its flat‑system architecture effectively reduces end‑to‑end latency. Targeting payload‑constrained platforms such as UAVs and mobile robots, it delivers integrated wireless transmission for HD video, flight‑control commands and sensor data in public‑network‑denied areas.
The module supports multi‑hop MESH networking. Mobile nodes rapidly re‑join the network when re‑entering coverage after temporary disconnection. Routing tables update automatically upon topology changes, and isolated sub‑networks can merge quickly. Equipped with automatic frequency‑hopping, adaptive transmit‑power and packet‑retransmission anti‑interference capabilities, it is a preferred lightweight communication solution for aerial relay, field inspection and emergency‑rescue applications.
