SMG - Slotted Microwave Guide

With SMG, VAHLE is able to provide a fully secure, wireless, contactless and interference free data transmission system with available data rates up to 100Mbps. Full duplex communications, multiple interfaces and 3 distinct profiles make SMG a viable solution for any application. The SMG system operates using a specially designed housing that operates to keep the wireless transmission isolated within the housing, free of any outside interference. Additionally, this keeps the SMG from interfering with any additional equipment on site. A wireless signal is sent from the stationary transceiver through the SMG profile to the mobile transceiver via the antenna trolley.
