Planning Gathering Site Requirements and Information
Gathering Site Requirements and Information
Make a preliminary visit to the site to gather information described in this section.
Obtain a Floor Plan
Obtain a floor plan with a distance scale and note the following items on the drawing:
Metal walls or concrete walls greater than 1M thick
Screen rooms
Large metal objects, such as cabinets and machines
Radio frequency sources, such as RF welders and WiFi
Stairwells or similar openings where floor-to-floor transmissions might be enhanced (for multi-floor
Identify Interference Sources
Check the customer for any pre-existing DECT use, such as a large number of DECT headsets or
residential DECT systems.
If possible, perform an RF analysis of the DECT band to check for interfering devices from neighbors.
Plan to disable any residential DECT systems at the time when you install the IP930D system.
Clarify Coverage Expectations
Make sure you understand which areas of the site require coverage, including outdoor or warehouse
spaces. Also understand if continuous coverage with handoffs is expected for multi-floor or multi-
building sites.
Because the system does not support call handoffs between bases (but only between a base and its
repeaters), your ability to provide continuous coverage with handoffs is limited by the coverage range
that your repeaters offer. This range varies by site and might not prove adequate for a multi-building or
campus environment.
Consider Traffic Capacity
The IP930D system is designed to be non-blocking in most cases. However, for future reference it is
good to understand the call frequency and talk times per hour for handset users. Consider locating a
base in the area where the majority of users spend most of their talk time.
