KIRK Wireless Server 600v3 Installation and Configuration Guide
Chapter 3 Deploying KIRK Wireless Server 600v3
Before you install the KWS600v3 Solution, it is necessary to perform a complete site
survey and determine the exact location of KWS600v3 primaries and secondaries and
number of handsets required.
A well planned installation should start with an RF coverage site survey. A site survey is
designed to determine the optimal location for KWS600v3 and repeaters and the amount
of wireless voice traffic to be supported by the installation (i.e., how many handsets must
maintain voice conversations at the same time, in any given area).
Due to the unexpected nature of RF propagation in an indoor environment, an actual
on-site test must be performed before the installation is complete. While an extensive
guide to effective RF coverage planning is outside the scope of this manual, the following
points should be taken into consideration when planning the site, prior to KWS600v3 and
repeater installation:
• The KWS600v3/repeater provides typical RF coverage of up to 50 meters/164 feet in
a typical indoor office environment and up 300 meters/984 feet in an open area
(line-of-sight), extending in all directions from the KWS600v3/repeater. The exact
coverage range depends on the building architecture, wall material and
surroundings.
• The wireless solution can support a maximum of 1500 handsets.
• The wireless solution supports a maximum of 256 radio units (a mix of primary and
secondary KWS600v3 and repeaters.
• Handset handover: handsets can move between coverage areas of primary and
secondary KWS600v3 and repeaters while receiving continuous service and
maintaining conversations in progress.
• For efficient handover of conversations between KWS600v3 primaries and
secondaries, deploy KWS600v3 with wide overlap between them (i.e., plan for some
areas to be covered by more than one KWS600v3). Overlaps are necessary to maintain
seamless handover and to establish synchronization chains. A good example may be
a cafeteria during lunch hour where temporary concentrations of handsets may
occur. The overlap carries the excess call load to adjacent KWS600v3 to provide
uninterrupted services to subscribers.
• Typically, installations such as office buildings, hotels and hospitals should be
equipped with KWS600v3 and or repeaters on several floors to create uniform and
complete RF coverage.
• Open areas can be covered with a sparse network of KWS600v3. In such applications,
the KWS600v3 and or repeaters cover an extended range due to the extended
line-of-sight RF propagation capability.
• Ensure that there is not a residential DECT system (home DECT) on the site.
