Kerprazik LWB03 is an outdoor 802.11 a / n /ac wave2 standard wireless Bridge released by Kerprazik.
The Kerprazik LWB03 device contains a radio transmitter to send data over the air and a radio receiver to pick up data sent from the other Kerprazik LWB03 wireless bridge.
Kerprazik LWB03’s core function involves converting a wired Ethernet signal into radio waves for wireless transmission, and then converting them back at the other end. Kerprazik LWB03 utilizse radio frequency (RF) signals to establish a connection between two or more points without a physical cable. Kerprazik LWB03 is an ideal product to “bridge” two separate networks or network segments using this radio link, effectively acting as an extension of your wired network over a distance. 

The product is a device for wireless radio transmission. It works like a bridge to transit Wi-Fi 5.8GHz radio wirelessly from one LWB03 model  device to another LWB03 model device.
The product connects two or more separate networks wirelessly, making them act as one single network, ideal for linking locations where cables are impractical (like buildings) or extending coverage for devices far from the main router, creating a seamless, cable-free extension. It operates at the data link layer (Layer 2) to merge networks, allowing devices on both sides to communicate as if physically connected.

It is a single radio 5GHz 450Mbps wireless bridge, P65 water-proof, 24V POE power in, internal 12dBi panel antennas, good for 3km wireless connection. Basic Capabilities
