Overview Components of the NetGuard Network
1.1.2 Telemetry Infrastructure
The NetGuard telemetry infrastructure consists of a network of ceiling-mounted access point
devices (shown in FIGURE 1-3).
FIGURE 1-3 Access Point Device
Each access point is connected via wireless subnet to the NetGuard devices in its sector. For
proper coverage, the access points should be spaced in contiguous sectors, each having a
maximum 30-foot radius.
NOTE: Subnets operate in accordance with the 802.15.4 wireless
standard.
The individual access points are hard-wired to the NetGuard server and communicate using
the Ethernet (POE) standard.
1.1.3 NetGuard Central Server
The NetGuard central server hosts the patient database and distributes patient data to client
applications running on the hospital terminals. The server is medical grade and
internationally compliant. The web server application runs over Microsoft
®
Windows Server
2003 Standard and communicates with the NetGuard devices (through the access points)
using Datascope’s WELAN protocol. Each NetGuard central server can support up to 300
patient’s.
1.1.4 Terminals
Clinicians gain access to the NetGuard system through the Monitor Application that runs on
terminals located in hospital nursing stations and at specific remote locations. The Monitor
Application controls the display of alarms and patient heart rate data. It also supports
management functions including patient admission to and discharge from the NetGuard
system. System users can print reports and related patient information through the Monitor
Application reporting functions.
