• Supports FHSS inside each band
• 1.4/3/5/10/20/40MHz band widths
• Max 100Mbps throughput
• RF transmission power: 24±1 dBm *2 channel
• Constellation: QPSK, 16QAM, 64QAM, self-adaption
• Sensitivity: -95dBm(20MHz bandwidth)
• Supports IP data transmission(3 Ethernet port)
• Supports serial data transmission(1 channel, RS232)
• Up to 22km LOS (UAV-to-ground) and 2km LOS(ground-to-ground)
• Web UI or control uart for management
• AES128 encryption
• Uplink and downlink stream control
• Networking mode: Point-to-Point, Point-to-Multipoint, Relay, mesh(specify)
• Movement Speed: Supports no less than 120km/h
• Power input: 9~30V
• Power consumption<7W
• Dimensions: 80*57*9.1mm
• Weight: 41g

Wireless networking with DLC

DLC module supports two operating modes: Access Node or Central Node. It can be managed through Web UI or AT command via control uart. DLC module supports features of maximum 63 Access Nodes connected to a Central Node. All of the Nodes are in a same wireless LAN and share the whole transmission bandwidth (maximum 100Mbps throughput). Data from Central Node to Access Node, we call downlink, and data from Access Node to Central Node, we call uplink. Uplink and downlink stream ratio can be controlled through web UI or AT command. When using DLC module for Point-to-Point transmitting, uplink and downlink share the whole transmission bandwidth (maximum 100Mbps throughput) too. DLC module supports networking mode: Point-to-Point, Point-to-Multipoint, Relay, and Mesh (specify mesh version when order).

Add Tx Power Amplifier

The maximum RF transmission power of DLC module is 24±1 dBm(2 channel), Sihid also provides power amplifier to increase the RF Power to 2W/5W/10W. Below diagram shows how to add power amplifier outside of the DLC module.
