Features: The wireless transmission distance can reach to lkm, professionally solve outdoor point to point, point to multi-point long distance wireless transmission and coverage problems. 3 modes for selection-Bridge mode, AP mode and router mode, to meet the needs of outdoor WiFi engineering applications. The transmitting power is linearly adjustable. You can reasonably adjust the transmitting power of the wifi bridges according to the actual environment, to reduce the mutual interference between the wifi bridges, and improve the stability of wireless transmission. Built-in high-gain dual-polarized antennas, longer transmission distance. Designed with 8 indicator lights, the signal strength is at a glance. Support 9V-21V POE and DC two power supply modes, you can select the suitable power supply way according your demands. Wide application range, suitable for aquaculture/forest/driving school/road/tourist/construction sites monitoring, and community/scenic spot/remote regions network transmission, etc. Specification: Model: CF-E315D Antenna: Built-in 2*12dbi intelligent antennas Standard: IEEE802.11b/g/n Transmit power: 82mw(19dbm) Receiving sensitivity: -96dbm Frequency: 802.11b/g/n: 2.412-2.472GHz Wireless speed: 300Mbps Port: 1*10/100Mbps WAN RJ45 Ethernet port, 1*10/100Mbps LAN RJ45 Ethernet port, 1*RESET/Digital switch, 1*AP/STA switch, 1*DC power supply port Indicator: 8*Indicators Power supply: 9V-21V POE power supply, support DC power supply Power consumption:
