D-Link DAP-3712 20KM 5GHz Outdoor Wireless Bridge

Connect Separated Sites with a Planned Wireless Bridge The D-Link DAP-3712 carries a network connection across a clear outdoor link using a directional 23 dBi antenna and 5 GHz Wi-Fi 5 radio. It is designed for installations where laying a cable between buildings, remote equipment or another network location is difficult. The manufacturer specifies links up to 20 km between two matching units under suitable conditions. This is a purpose-built wireless bridge rather than a cellular 5G router or a general indoor Wi-Fi access point. Correct alignment, an unobstructed radio path and an appropriate power and mounting arrangement matter more than the advertised distance alone. Plan the link at both ends, including the receiving equipment, local radio regulations and the network connection behind each unit. Highlights Directional Outdoor Connectivity 23 dBi integrated directional antenna Manufacturer-rated distance up to 20 km between two matching units Point-to-point and point-to-multipoint deployment options Wireless Link Control 5 GHz IEEE 802.11a/n/ac radio Up to 867 Mbps maximum wireless signal rate TDMA, automatic ACK and intelligent rate control Practical Installation 1 × Gigabit Ethernet port IP66-rated ABS enclosure 48 V PoE input using the correctly matched power equipment Key Features Bridge a Gap in the Network Use a matching bridge at each end to connect a remote network location without running a cable along the entire route. A clear line of sight and adequate Fresnel-zone clearance are essential. Trees, new structures, terrain, interference and mounting movement can reduce the usable link quality. The up-to-20-km figure is a planning limit under suitable conditions, not a promise for every site. Align the Directional Antenna Carefully The integrated 23 dBi antenna concentrates coverage along the intended link. Its published beamwidth is 10° horizontally and 10° vertically. Secure mounting, accurate alignment and a stable pole or bracket help maintain the radio path. This directional design serves a different purpose from an omnidirectional access point used to cover people moving around a room or outdoor area. Manage Airtime and Diagnose the Link TDMA gives transmissions scheduled airtime, while automatic ACK timing and rate control help the bridge adapt to a long-distance connection. The management tools include a spectrum analyser, throughput testing, ping, traceroute and a ping watchdog. Use these tools alongside a site survey and a realistic traffic plan; the 867 Mbps radio rate is not an end-to-end throughput guarantee. Match Power and Outdoor Protection The DAP-3712 is specified for 48 V PoE input, and the manufacturer lists a PoE injector with the product. Use the matching supplied power equipment rather than assuming every PoE source is interchangeable. The IP66 enclosure and manufacturer-listed 8 kV protection still require correctly sealed cable entries, suitable outdoor cabling, earthing and surge protection appropriate to the site. Keep the Bridge and Client Wi-Fi Roles Clear A building-to-building bridge transports the network between locations. A separate access point may still be needed to provide convenient Wi-Fi coverage for phones, laptops or other clients at the remote end. Configure the appropriate bridge mode, addressing, VLANs and security policies for the wider network. The unit does not replace an internet subscription, router or firewall. Summary The DAP-3712 combines a 23 dBi directional antenna, 5 GHz wireless link controls and an IP66 outdoor housing for planned connections between separated network locations. Choose it around the actual radio path, mounting, traffic and power requirements, with a matching unit or compatible link equipment selected for the other end. Frequently Asked Questions Do I Need Two Units for a Building-to-Building Link?ExpandCollapse A typical point-to-point installation uses a matching unit at each end. The manufacturer’s up-to-20-km reference is specified between two DAP-3712 units. This listing represents the existing individual product offer; do not assume that a complete two-unit link is supplied unless your order explicitly identifies a pair. Is This a Cellular 5G Router?ExpandCollapse No. It uses the 5 GHz Wi-Fi radio band to bridge a network connection. It has no cellular 5G modem or SIM service. An internet gateway or another network source is still required where the installation needs internet access. Will It Reach 20 km at Every Site?ExpandCollapse No. That is the manufacturer’s maximum bridging-distance reference between two matching units under suitable conditions. A clear line of sight, Fresnel-zone clearance, correct antenna alignment, legal transmit settings and an interference assessment are important. A site survey is needed to assess a real installation. Does 867 Mbps Mean the Same Internet Speed?ExpandCollapse No. It is the maximum wireless signal rate under the Wi-Fi standard. Actual application throughput is lower and depends on radio conditions, channel width, interference, traffic, network overhead and the equipment at each end. Your internet service remains a separate limit. Can I Connect It to Any PoE Switch?ExpandCollapse Do not assume that. The manufacturer specifies 48 V input for this model. Use the correctly matched included injector or power equipment explicitly suitable for the unit. Confirm the voltage, polarity and connection method before applying power. What Does IP66 Protection Mean for Installation?ExpandCollapse The enclosure is designed to resist dust and powerful water jets when correctly installed. It does not remove the need to seal cable entries or use appropriate outdoor cabling, mounting, earthing and surge protection. The listed 8 kV protection is not a guarantee against lightning damage. 더 보기
