The Steam Console Client or SteamCMD is a command-line version of the Steam client. Its primary use is to install and update various dedicated servers available on Steam using a command-line interface. It works with games that use the SteamPipe content system.
Directional antennas should be used for point-to-point wireless transmission. The type of directional antenna depends upon the power output, cable type and length, height, distance, data rate and terrain. We recommend the use of a range table to estimate the wireless antenna types.
The reason someone might use this is to establish a wireless point-to-point connection between two sites, such as for the building in which you saw the device. Or there may be a need to place an antenna in a location far away from where the network equipment will reside, such as up on a tower.
