RF specic functionalities and

effective performance claims

The ACCU-CHEK Inform II system includes an optional

module for wireless network connectivity (RF card). This

module can only be congured 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 recongured 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 specic 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 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).

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. Upon receipt of this DMS query, the meter

will re-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.
