3.3 Flex-AP Access Point
The access point is effectively a wireless gateway that maintains two-way wireless links
to the sensors and repeaters. It establishes overall time synchronization, transmits
configuration commands and message acknowledgements, and receives and processes
data from the sensors.
The access point has a wired connection (via a RJ45 connector) to relay the
magnetometer sensor detection data to a roadside traffic controller via an interface card.
Table 4 : Acccess Point (AP)
There are multiple variants of the access point that have been provided by the
manufacturer, Sensys Networks Inc, however Siemens supply the Flex-AP variant only.
The access point requires 48V supply, which is derived from a PoE interface, via an
appropriate street Ethernet cable.
