• Supports 806~826HMz band or 1428~1448MHz band
• Supports FHSS inside each band
• 1.4/3/5/10/20MHz band widths
• Max 30Mbps@20MHz throughput
• RF transmission power: 2W or 5W
• Constellation: QPSK, 16QAM, 64QAM, self-adaption
• Sensitivity: -108dBm(1Mbps)
• Supports IP data transmission(2 Ethernet port)
• Supports serial data transmission(3 channel, RS232 or TTL)
• 1~5km(ground-to-ground), 17~100km(UAV-to-ground, optional distance grade)
• Web UI or control uart for management
• AES128 encryption
• Uplink and downlink stream control
• Networking mode: Point-to-Point, Point-to-Multipoint, Relay, and Mesh(specify)
• Movement Speed: Supports no less than 120km/h
• Compact size and light weight
• Rugged aluminum alloy housing
• Power input: 12~18V(2W), 24~28V(5W)
• Power consumption<12W(RF Power 2W), <22W(RF Power 5W)
• Dimensions: 103.4*61.4*22mm
• Weight: 142g

Wireless networking with SDL532

SDL532 supports two operating modes: Access Node or Central Node. It can be managed through web UI or Control uart. SDL532 supports features of maximum 16 Access Nodes connected to a Central Node. All of the Nodes are in a same wireless LAN and share the whole transmission bandwidth (maximum 30Mbps@20MHz 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 Control uart. When using SDL532 for Point-to-Point transmitting, uplink and downlink share the whole transmission bandwidth (maximum 30Mbps@20MHz throughput) too. SDL532 supports networking mode: Point -to-Point, Point-to-Multipoint, Relay, and Mesh (specify mesh version when order).
