The current RF system consists of an antenna and a
WLAN system-on-chip (SoC) along with other compo-
nents. The WLAN system-on-chip is the core of the
WLAN system. The RF system used in the Accu-Chek
Inform II meter specifically adheres to the following
specifications:
■ Its WLAN system-on-chip supports IEEE 802.11b
and 802.11g. It works seamlessly together with other
Wi-Fi certified transceivers. It also implements the
Wi-Fi Protected Access (WPA™ - Enterprise and
WPA™ - Personal), Wi-Fi Protected Access 2
(WPA2™ - Enterprise and WPA2™ - Personal), and
Wired Equivalent Privacy (WEP) security mecha-
nisms with Temporal Key Integrity Protocol (TKIP)
and Advanced Encryption Standard (AES).
In addition, the system supports the extensible
authentication protocol (EAP) with EAP-TLS, EAP-
TTLS/MSCHAPv2 and PEAPv0/EAP-MSCHAPv2.
The Accu-Chek Inform II meter interoperability
Wi-Fi certificate can be accessed at

Further information including a glossary of terms,
frequently asked questions, and other topics related
to Wi-Fi technology can be found on the Wi-Fi Alli-
ance site (http://www.wi-fi.org/).
■ The used channels in the 2.4 GHz-band are chan-
nels 1-11, which are the legally allowed channels in
the USA. (Channels 12-14 are not used by the
Accu-Chek Inform II meter.)
■ RF output power is approximately 15 dBm at a data
rate of 54 MBPS.
Note: For technical reasons, only client certificates in a
*.pem file format are acceptable for EAP-TLS authentica-
tion. In a Windows-based network environment, *.pfx
files need to be converted to *.pem format. It is in the
responsibility of the customer / customer’s IT department
to convert *.pfx certificates to the required *.pem format.
