1. Wireless Ethernet Product Description
a. Overview of Spacelabs Wireless Networks
Spacelabs wireless ethernet allows connection between a conventional wired ethernet network and a
wireless (radio) ethernet network. This enables the two networks to function as one.
Wireless ethernet provides 1 to 5 outbound waveforms and numeric vital signs. The wireless ethernet
option applies to the 90309-W PC Ranger, the 90367-Z Ultraview 1030, the 90369-Z Ultraview 1050, and
the 90385-Z wireless Universal Clinical Workstation (UCW).
Wireless ethernet uses 2.4GHz two-way cellular radio communications to transmit and receive patient
data. Waveforms, alarms, numeric data, bed information and configuration messages can be transmitted
from the bedside/transport monitor, “slave”, to the rest of the network through one Wireless Network
Interface, “master”. For ambulatory patients, an array of Wireless Network Interface devices is used to
provide complete cellular coverage. The Wireless Network Interface (WNI) serves as the wireless access
point to the hardwired ethernet LAN. With optional interactive networking, bed to bed access is possible.
As shown below, wireless monitors use a radio link to communicate with a Wireless Network Interface
(WNI). The wireless monitors each synchronize their communications with one WNI, referred to as a
“master”. The WNI completes the ethernet link to the hard-wired network.
