The loss of signal or access to bandwidth of one particu-
lar client may vary depending on one or more of the
following situations: the type and number of other clients,
the performance of the Access Point, the presence of
electromagnetic disturbances, and other potential inter-
fering factors, e.g., concrete walls.
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 band-
width 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 per-
formance to support any new radio frequency (RF) appli-
cation 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 one
base unit be hard wired per floor. A networked base unit
provides redundancy if a wireless network malfunctions
or loses service. If the Accu-Chek Inform II meter with RF
is used in an area with low signal or interferences, it is
recommended to install a connected base unit for redun-
dancy. The redundancy of the connected base unit allows
immediate transmission of patient results when the meter
is docked.
