B Appendix
B.1 Option: Wireless network (WLAN)
Preliminary note
Appendix B has been developed to explain the wireless communication principles of the
cobas h 232 system
1
and to help your facility’s information technology/management team(s) in
effectively deploying the cobas h 232 system on your wireless network.
Whether your meter is equipped with WLAN functionality or not depends on the system
configuration that you purchased.
For information on WLAN registration see the addendum “WLAN registration information,
Addendum to the Operator’s Manual for cobas h 232” which can be downloaded from the
“Point of Care testing” area at www.cobas.com.
Background
The cobas h 232 meter can only be configured through a data management system to commu-
nicate wirelessly. The data management system is also used to set-up and configure the meter to
connect to one hospital specific Wireless Local Area Network (WLAN
2
). WLANs use electro-
magnetic waves in the 2.4 and/or 5.0 GHz frequency range to wirelessly transmit data
3
. The
cobas h 232 system adheres to IEEE Standard 802.11g (2.4 GHz range)
4
. The system is back-
wards compatible to 802.11b. During wireless communication to an Access Point (AP), the
cobas h 232 meter recognizes the existent AP WLAN protocol configuration (802.11b or
802.11g) and automatically transmits data using the appropriate communication protocol
5
.
1. The cobas h 232 system is certified by the Wi-Fi Alliance.
2. WLAN is also commonly referred to as wireless LAN or Wi-Fi.
3. For the wireless functionality to work properly, the wireless module must first be configured by your
system administrator.
4. While the cobas h 232 system adheres to the 802.11g standard, it uses only channels 1-11. Channels
12-14 are not used by the system.
5. WLANs are organized in cells. A typical WLAN cell consists of Access Point(s) that are connected to
the (wired) Local Area Network and one or more clients, e.g., cobas h 232 meters along with other
clients such as portable computers.
