4120C Case Type Netbridge

4120C

4120C network system is a two-way wireless bridge system developed for non-line-of-sight applications. It can transmit two-way full-duplex images, voice , data and can run all network applications as long as the data rate of application is within the allowable range. The system provides 2 * 1.7Mbps ~ 2 * 30 Mbps Ethernet bandwidth. Can support high-speed mobile carrier (car, ship, aircraft) in the computer directly connect to the headquarters

4120C can transmit high-quality video images in high-rises cities or in environments with serious multipath effects (sea clutter) such as sea surface. It has excellent "diffraction" ability and "penetration" ability of buildings, which can achieve a wide range of coverage without the need for directional antenna. It can work stably and reliably on all kinds of moving platforms such as vehicles, ships and aircraft.

The frame type netbridge equipment ZT4120C is a standard 3U industrial chassis, which can be directly loaded into the 19 inch standard industrial chassis.
