B Appendix
B.1 Option: Wireless network (WLAN)
Preliminary note Appendix B has been developed to explain the wireless
communication principles of the Accu-Chek Inform II
system
1
and to help your facility’s information technology/
management team(s) in effectively deploying the
Accu-Chek Inform II system on your wireless network.
Whether your meter has wireless capability or not
depends on the system configuration that you purchased.
Background The Accu-Chek Inform II meter can only be configured
through a data management system to communicate wire-
lessly. 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 2.45 GHz and/or 5.15 - 5.25 GHz
and/or 5.725 - 5.850 GHz frequency range to wirelessly
transmit data
3
. The Accu-Chek Inform II system adheres to
IEEE Standard 802.11g (2.45 GHz range)
4
. The system is
backwards compatible to 802.11b. During wireless com-
munication to an Access Point (AP), the Accu-Chek Inform
II meter recognizes the existent AP WLAN protocol config-
uration (802.11b or 802.11g) and automatically transmits
data using the appropriate communication protocol

.
1. The Accu-Chek Inform II 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 wire-
less module must first be configured by your system
administrator.
4. While the Accu-Chek Inform II 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 con-
sists of Access Point(s) that are connected to the (wired)
Local Area Network and one or more clients, e.g.,
Accu-Chek Inform II meters along with other clients such
as portable computers.
