The ACCU-CHEK Inform II meter uses a burst-like

commu nication protocol that will only consume

bandwidth if there is actually data to be transferred.

Compared to other applications, such as Voice over

Internet Protocol (VoIP) or multi-media applications, the

meter’s bandwidth consumption is minimal. If the WLAN

that the ACCU-CHEK Inform II meter seeks to connect to

is degraded, the meter design minimizes the impact on

functionality.

Technical implementation

Prior to connecting any wireless device to a wireless

net work, it is recommended that a WLAN site survey be

per formed. The goal of a WLAN site survey is to ensure

that Access Points will provide enough coverage and

perfor mance to support any new radio frequency (RF)

applica tion or device. The survey will also detail RF

signals, including all existing WLANs along with any

competing RF signals and interferences (building

structure related and other wireless equipment / devices).

As part of an RF implementation of the ACCU-CHEK

InformII system, it is recommended that at minimum a

base unit be hard wired via an RJ-45 network jack per

oor. A net worked base unit provides redundancy if a

wireless net work that the ACCU-CHEK Inform II meter is

using malfunctions or loses service. If the ACCU-CHEK

Inform II meter with RF is used in an area with low signal

or inter ferences, it is recommended to install a connected

base unit for redundancy. The redundancy of the

connected base unit allows immediate transmission of

patient results when the meter is docked.

The ACCU-CHEK Inform II meter uses a wireless (RF)

card in compact ash (CF) card format to implement the

WLAN functionality. Depending on the system

conguration that you purchased, the meter will either

already be equipped with a WLAN card (catalog no.

05060303001) or you may purchase the card later

(catalog no. 05060311001).
