The current RF card consists of an antenna and a WLAN

system-on-chip (SoC) along with other components. The

WLAN system-on-chip is the core of the WLAN system.

The RF card used in the ACCU-CHEK Inform II specically

adheres to the following specications:

n Its WLAN system-on-chip supports IEEE 802.11b

Direct Sequence Spread Spectrum and 802.11g

Orthogonal Frequency Division Multiplexing

base band modulation, and Medium Access

Controller. It works seamlessly together with WLAN

RF trans ceivers. 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 mechanisms 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

n Used channels in the 2.4 GHZ-band are channels

1-11, which are the allowed channels in the USA.

(Channels 12-13 are not used by the ACCU-CHEK

Inform II meter.)

n RF output power is approximately 13dBm at a data

rate of 54 MBPS.
