The Accu-Chek Inform II system includes an optional
module for wireless network connectivity (RF card). This
module can only be configured by a data management
system (DMS), which enables the meter's wireless com-
munication and data transfer capabilities. Wireless con-
nectivity can help to ensure that updates to information in
the DMS are sent immediately to all networked meters.
Meters with an integrated RF card and wireless enabled
use the base unit for recharging and/or as a redundant
communication option to exchange data with the DMS.
The meter also has to be docked if the hospital changes
security protocols. When this change occurs , it may lock
out all meters until docked and reconfigured with the
new protocol.
As described above, the Accu-Chek Inform II meter
supports the 802.11g standard. This translates into the
following RF specific performance claims:
The Accu-Chek Inform II meter is capable of trans-
■
ferring to a suitable DMS, via WLAN, a data set of
up to 2000 result records, 100 reagent records, and
500 operator ID records in less than 15 minutes,
when operated in a typical WLAN environment
(correct WLAN administration, typical population of
other clients present, any of the supported security
models enabled).
Immediately after the operator has initiated the
■
sending of a blood glucose result, the Accu-Chek
Inform II meter will attempt to connect to the DMS.
In line with the industry communication standard
POCT1-A, the DMS must acknowledge the meter's
request for connection and actively query for the
result. Upon receipt of this DMS query, the meter
will re-send the result. Hence the effective time for
transmitting results depends on infrastructure,
DMS workload, etc. Once the DMS sends a query,
however, the meter will respond within a few
seconds.
