RF specific functionalities and
effective performance claims
The ACCU-CHEK Inform II system offers the option of
wireless network connectivity (WLAN/Wi-Fi). If you
purchase a system with this option, the WLAN function is
enabled during production.
This module can only be configured by a data
management system (DMS), which activates 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 and activated wireless option
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
sup ports the 802.11g standard. This translates into the
fol lowing RF specific performance claims:
n
The ACCU-CHEK Inform II meter is capable of
trans ferring to a suitable DMS, via WLAN, a data
set of up to 1000 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).
n
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. Only upon receipt of this DMS query, the
meter will send the result. Hence the effective time
for trans mitting results depends on infrastructure,
DMS workload, etc. Once the DMS sends a query,
how ever, the meter will respond within a few
seconds.
