FDAP description

Note that in this document, a reference to wireless field devices include ISA100 Wireless devices,
WirelessHART devices, and Wired HART devices unless otherwise mentioned. Specific device type will be
mentioned as and when applicable.
The Field Device Access Point (FDAP) is a ruggedized industrial radio device intended for use in
hazardous location to provide wireless connectivity for Wireless compatible field devices. As an
industrial meshing access point, FDAP provides secure and reliable wireless coverage for wireless
field devices. It also serves as a routing access point for wireless field devices and is located
between the wired DCS network and wireless-based wireless field devices. Once deployed in the
field, FDAPs self-discover and self-organize into a managed, secure, and redundant wireless field
device mesh network. With FDAPs, wireless field devices do not have to route data from other
field devices. The following figure illustrates how FDAPs are used in a OneWireless Network:
FDAP uses IEEE 802.15.4 standard based radio technology and combines spatial diversity with
advanced error correction schemes to communicate in a complex multi-path environment and in
large communication areas. It has an Ethernet interface for connection to the backbone network
and a wireless compliant radio to connect to the wireless field device network. It is a standalone,
pole mountable, intrinsically safe device, suitable for use in hazardous locations. It is normally
installed in the same area where industrial field devices are installed. FDAP supports 10/100 Mbps
Fast Ethernet and has spatial antenna diversity.
