R&S®IPoA protocol functionality
The embedded R&S®IPoA protocol currently supports Internet
protocol version 4 (IPv4). An internal address mapping
function ensures that data is delivered to the correct
recipient. The IP packets are transmitted transparently over
the radio channel. Data link performance depends on the
current channel properties and propagation conditions of
the radio link. An error detection mechanism prevents the
protocol from delivering erroneous data to the connected
network; further error correction techniques (e.g. ARQ secured
data) are implemented.

R&S®IPoA message service
Messages and text information can be transmitted directly
from the radio HMI as well as from external sources.
Each R&S®IPoA-capable waveform supports the following
applications:
Alarm messages
Alarm messages are messages that are preconfigured during
mission planning. They can be selected on the HMI
and then transmitted. Alarm messages place almost no
load on the channel and are therefore always transmitted
with the highest priority
Short data messages
Short data messages (SDM) can be entered directly on
the HMI keyboard (similar to entering an SMS on a mobile
phone). Addressing (PtP, PtM) is possible depending on
the underlying waveform.
