General Information
Definitions
The Master transceiver performs communications with an OBU
autonomously. It basically includes the functionality of radio module and
controller software to perform the communication with the OBU. It can be
used as a standalone device or in conjunction with one slave transceiver.
Slave transceivers are able to perform communications with OBUs by the
use of a transceiver controller. The communication is initialized and
controlled by the transceiver controller, and forwarded by the transceiver. In
this application the transceiver acts as a wireless bridge.
Multiple transceivers may be combined in a modular architecture to cover
specific communications areas.
The transceiver controller performs the application by using the slave
transceiver as a wireless network bridge. The transceiver controller further
provides the interface to the host e.g. lane controller, central system.
The size of the communication zone is defined as the space within
communication with another device (e.g., OBU) is reliable. The size of the
communication zone is mostly influenced by the mounting height and
mounting angle of the transceiver, the antenna utilized and the maximum
power level used.
