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.
For example, the point-to-point tunneling protocol (PPTP) is based on GRE, and GRE is used with IPsec to transmit routing protocol data from one router to another, which IPsec does not natively support. See tunneling protocol, PPTP and IPsec.
