Indoor Subscriber Unit (SUI) Connectivity Issues
Predicting link budgets for indoor links is exceedingly difficult, as there are many factors
which affect the path loss of an indoor link, which do not apply to outdoor links of similar
distances. Use the following list of steps to take, to establish a connection or to improve
an existing connection, when using an indoor subscriber station (SU-I).
If the subscriber station is located next to a window, ensure that the window does not
contain any metal. Many windows contain lead to reduce incident sunlight, or may be
inter-woven with a metal wire mesh to increase their strength.
If you do not have an appropriately facing window, place the subscriber unit near an
exterior wall facing the direction of the sector controller. Interior walls and obstructions
such as appliances and the building’s metal framework can severely impact link quality.
Place the subscriber unit as high as possible. Moving the subscriber up away from the
clutter of a room can significantly improve link quality. Objects such as desks, chairs, filing
cabinets, even people walking in and out of a room within the path of the subscriber unit
can disrupt the link.
Gauging Link Performance
In order to be able to gauge how well a sector or even a particular wireless link is working
it's important to understand what statistics to monitor, and how to interpret them. The
statistics available on the AN100U/UX and its subscribers differ, as each device has
different information available. It's important to observe the statistics available on both
devices before attempting to come to any sort of conclusion.
AN100U/UX
In general, the AN100U/UX is able to display statistics regarding the quality of the uplink
signal received from any given subscriber, as well as the overall status of the sector's
traffic and health. It also displays some basic information regarding signal levels in the
downlink, which are reported to the AN100U/UX by the subscribers. The following table
lists the statistics/parameters to monitor, and a brief description on how they should be
interpreted.
You can access these parameters on the Status and SS Info pages of the sector
controller‘s web interface. See “Monitoring Statistical Results Screens” on page 2-8.
