Good Example:
The Master CS is located in the centre of the installation site for each Air Sync Group.

Bad Example:
The Master CS is
NOT
located in the centre of the installation site for each Air Sync Group. Therefore, the
number of layers in the hierarchy exceeds 8.

Notice
•
Choosing the best site for the SIP-CS requires careful planning and testing. The best location may not
always be convenient for installation.
•
It is necessary to locate SIP-CSs within synchronisation range of other SIP-CSs, however, locating
SIP-CSs too close to each other can lead to interference and a reduction in the number of simultaneous
calls. In a regular office, the average distance between SIP-CSs should be approximately 30 m.
However, since walls, metallic shelves, etc. can weaken signals, air synchronisation may not be as
stable as planned. Conduct a site survey after installing the SIP-CSs, as described in "4.3 Site
Survey".
Understanding Radio Waves
Characteristics of Radio Waves
The transmission of radio waves and the SIP-CS coverage area depend on the structure and materials of the
building.
Office equipment, such as computers and fax machines, can interfere with radio waves. Such equipment may
create noise or interfere with the performance of the S-PS.
The illustration below shows the special transmitting patterns of radio waves.
