The loss of signal or access to bandwidth of one
particu lar client may vary depending on one or more of
the fol lowing 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 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 one
base unit be hard wired per floor. A net worked base unit
provides redundancy if a wireless net work 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.
