SIEMENS IWLAN Distance Estimation Tool

When establishing a wireless connection for a particular application, the possible distance between the wireless devices depends on many parameters. The Siemens IWLAN Distance Estimation Tool helps you to collect all the necessary parameters. From the information entered, it allows a quick estimation of whether the planned setup is possible.
Device A
Device B
SCALANCE W700 model:

Note: max TX power: 20 dBm / min RX: -87 dBm

Transmit power:

DISCLAIMER
The range of a wireless connection can be calculated from the sum of the supplied power and all of the expected attenuations and gains. It must be noted that this is always a theoretical consideration which sometimes deviates from real setups. These deviations are normal and can be compensated to a certain extent by a system budget.
To realize a stable standard WLAN connection, a minimum received signal strength of -75dBm is recommended. To realize a stable IWLAN connection with deterministic communication a minimum received signal strength of -65dBm is recommended. Please ensure that the country-specific EIRP will not be exceeded.
