Background The CoaguChek Pro II meter can only be configured
through a data management system to communicate
wirelessly. The data management system (DMS) is also
used to set-up and configure the meter to connect to one
hospital specific Wireless Local Area Network (WLAN
1
).
WLANs use electromagnetic waves in the 2.4 GHz
frequency range to wirelessly transmit data
2
. The
CoaguChek Pro II system adheres to IEEE Standard
802.11g (2.4 GHz range)
3
. The system is backwards
compatible to 802.11b. During wireless communication to
an Access Point (AP), the CoaguChek Pro II meter recog-
nizes the existent AP WLAN protocol configuration
(802.11b or 802.11g) and automatically transmits data
using the appropriate communication protocol

.
The loss of signal or access to bandwidth of one particu-
lar client may vary depending on one or more of the fol-
lowing situations: the type and number of other clients,
the performance of the Access Point, the presence of
electromagnetic disturbances, and other potential inter-
fering factors, e.g., concrete walls.
The CoaguChek Pro II meter uses a burst-like communi-
cation protocol that will only consume bandwidth if there
is actually data to be transferred. Compared to other
applications, such as Voice over Internet Protocol (VoIP)
or multi-media applications, the meter’s bandwidth con-
sumption is minimal. If the WLAN that the CoaguChek
Pro II meter seeks to connect to is degraded, the meter
design minimizes the impact on functionality.
1. WLAN is also commonly referred to as wireless LAN or
Wi-Fi.
2. For the wireless functionality to work properly, the wire-
less module must first be configured by your system
administrator.
3. While the CoaguChek Pro II system adheres to the
802.11g standard, it uses only channels 1-11. Channels
12-14 are not used by the system.
4. 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.,
CoaguChek Pro II meters along with other clients such as
portable computers.
