The receiver system receives, demodulates, and decodes patient data received via the
antenna system from a transmitter. The decoded data is then transferred to the ATS
via the Unity Network RX network. Patient data is not stored on the receiver system.
An installation can have more than one receiver system. Each receiver system can
have up to 16 receivers. Each receiver can be associated with (and receive data from)
one ApexPro transmitter.
Refer to the ApexPro Receiver System documentation for further details.
The antenna system transfers information from the transmitter to the receiver system
for demodulation and waveform processing. Additionally, the antenna system
increases ApexPro reception range, allowing patients wearing transmitters to move
over an expanded area. As transmitters move around the facility, reception can switch
from one antenna to another as required to maintain RF signal coverage.
The antenna system includes the receiver antenna and all associated components up
to, but not including, the receiver system. There are two versions of the antenna
system: one for U.S. applications (560–614MHz) and one for international
applications (420–474MHz).
Refer to the ApexPro Antenna System site survey and installation manual for further
details.
The access point transceiver is an Ethernet gateway that collects data from the
ApexPro FH transceivers, transmits data to the telemetry tower on the OpenNet
Network, and sends or receives control data to/from the transceivers. The access point
is typically mounted above the drop ceiling with cosmetic antennas mounted below
the ceiling. The access point is similar in concept to conventional wireless LAN
access points (such as 802.11-compliant wireless LANs), but differs in having
enterprise-wide synchronization and a higher level of data throughput efficiency. This
is compliant with the WMTS rules for the 608 to 614 MHz band.
The transmitter connects to the patient and transmits patient telemetry data to the
antenna system (which in turn, sends that data to the receiver system). The transmitter
acquires patient data, converts it to digital format, and serially broadcasts the data
along with pace, additional parameters (from devices attached to the serial ports), and
status in an RF signal.
