Conducting A Site Survey; Gather Equipment For The Site Survey; Identify Interference Sources - ShoreTel 930D Planning And Installation Manual

2 Planning

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.

Conducting a Site Survey

Before you plan your installation layout, it is essential that you conduct a site survey to measure
handset coverage from the base station at the installation site. A site survey allows you to effectively
estimate the equipment needed to build your system.
It is recommended that you conduct the site survey during business hours to check for competing
DECT systems that might degrade performance of the installation.

Gather Equipment for the Site Survey

To conduct the site survey, you will need the following equipment:
A base station configured with a static address that is otherwise in a factory default state

A PoE mid-span power brick connected to a small Ethernet switch or hub

A fully charged handset
