<h1><span class="tf_a"><b>Radio Frequency</b></span></h1>
<p><span class="tf_a">The radio frequency module automates the communication between
the Transport Efficiency Support System SyncroTESS and the drivers. It sets
up a bi-directional interface between SyncroTESS and a transparent RF-system.
The displays of special handheld or vehicle mounted terminals show the proposals
which SyncroTESS makes for the transport orders. By pressing a key the driver
can accept or reject these proposals. Type and contents of the masks can be
customized for each client. Free text entries are possible, too. <br>
<br>
Depending on the RF- technology chosen (spread spectrum, narrow band, Digital
Cellular Network, DECT, etc.) different devices with varying performance features
can be used. <br>
