Analysis of the environmental conditions
When planning the installation of a SpeechLine Digital Wireless system, you should also
carefully analyze the environmental conditions. Are there any other 1.9 GHz devices (e.g.
DECT telephones or DECT access points) already installed?
Observe the following aspects when planning an installation
▷ Identify the locations of DECT access points (e.g. for DECT telephone systems). Also
observe the information provided under Shared use of the 1.9 GHz frequency band.
▷ Determine the type of installation, i.e. where and how the microphone receivers are to
be installed.
▷ Determine whether the antenna are to be mounted remotely from the receivers. When
remote mounting the antenna, also take into account possible losses due to long
cable runs. Also see Recommendations on antenna mounting.
▷ When installing remote antenna, observe a minimum distance of 3 m to the next
DECT access point.
▷ To make network control very simple, we recommend using a network switch to
connect the receivers in the network.
