Sihid SDL550 was designed for video and data wireless transmission with two way wireless data link. This OFDM radio device works at 800MHz or 1.4GHz bands, with frequency hopping technology (FHSS) to make sure better stability signal communication.

Features:

• TDD OFDM modulation
• 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: 10W
• Constellation: QPSK, 16QAM, 64QAM, self-adaption
• Sensitivity: -108dBm(1Mbps)
• Supports IP data transmission(2 Ethernet port)
• Supports serial data transmission(3 channel, RS232)
• 1~15km(ground-to-ground), 30~150km(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: 24~30V
• Power consumption<40W(RF Power 10W)

Wireless networking with SDL550

SDL550 supports two operating modes: Access Node or Central Node. It can be managed through web UI or Control uart. SDL550 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 SDL550 for Point-to-Point transmitting, uplink and downlink share the whole transmission bandwidth (maximum 30Mbps@20MHz throughput) too. SDL550 supports networking mode: Point -to-Point, Point-to-Multipoint, Relay, and Mesh (specify mesh version when order).
