666 Gira electrical installation systems eNet Planning information I Technical information Planning information eNet Optimum wireless connections and optimum use the ranges of wireless components are achieved observing the following basic rules: - The antennae the transmitters and receivers should, the greatest extent possible, all aligned vertically horizontally.2m Conditions: The mounting height the transmitter 2m – Moist ground . - Wireless components other function groups, wireless head- phones telephones, must kept least away. Dry material Penetration Wood, plaster, sheetrock approx.6m 18m 0. Wireless transmission occurs non-exclusive transmission path. Therefore, the open field range (Fig. Requirements for the measurement field ranges: - Level area - Horizontal distance interfering objects from each point the line connecting the transmitter and receiver 20m - Height the measured objects above the ground 2m - Alignment the measured objects for optimum contact - Moist ground ca. emergency-stop, emer- gency call etc. - To correct irregular reception, often sufficient move the transmit- ter receiver few centimetres. always stated, which refers undisturbed propagation radio waves and optimally aligned antennae. The wireless transmission is thus not suitable for security purposes, e. minimum distance should heeded here to prevent saturation. Dependence the transmission ranges the mounting height: Theoretical transmission ranges Mounting height the receiver 100m 2m 56m 1. We recommend not installing them lower than 0. 30% Metal, metal grids, aluminium cladding approx.degree of drying out spackle and plaster, and the existing doors and armour or hangings the windows into account. Measurement the range between the transmitter (A) and the recipient (B) and recommended distance from interfering factors (C). 1), the wireless range depends considerably the type construction materials penetrated and the effective wall thickness. - Large metal surfaces, such metal doors and frames, aluminium blinds metal cabinets should kept great distance possi- ble (several decimetres). Attenuation reduces the strength the wireless signal between the transmitter (A) and the receiver (B) Evaluating wireless paths buildings very difficult due multitude of influences. This reception interference often occurs due shadowing, obliteration, reflections the wireless signal sometimes occur with car radios and mobile telephones, for example. 70% Reinforced concrete approx. For this reason, interference cannot ruled out.from the wireless presentation case) for relia- ble wireless connection before using wireless components. - Transmitters and receivers are not installed behind metal con- ductive surfaces, such anti-static floors, sounding with metal clad- ding, cable lines, metal louvered ceilings and hot-water and electrical floor heating. - Electronic devices, such motors, electronic control gear and Tronic transformers, must kept distance least 50cm.5m 34m 1. g.5m from the ground.
