2 Procedure Overview

2 Procedure Overview

When connecting the wireless system, use extreme care in conducting the site survey. An incorrectly performed site survey can result in poor service area, frequent noise, and disconnection of calls.

IMPORTANT

•When installing the DECT 6.0 wireless system in an area where another wireless system (2.4 GHz) is already installed, it is necessary to reconduct the site survey to find the optimum position for the CS. If you install the new CS in the same position as the old CS, it may result in a poor service area, frequent noise, and disconnection of calls.

•In this case, it is necessary to perform system initialization. For details about the system initialization procedure, refer to "Starting the PBX" in the Installation Manual for your PBX.

1.Investigate the installation site

Refer to "3 Site Planning".

a.Obtain a map of the CS installation site.

b.Identify the service area required by the user on the map.

c.Plan the location of each CS, taking account of distance, building materials, etc.

2.Prepare for site survey

Refer to "4 Before Site Survey".

a.Check and assign the CS ID number to the PS.

b.Assign a channel number to each CS by setting the DIP switches on the back of the CS.

c.Supply electricity to each CS using an AC adaptor/battery box or by connecting them to the PBX.

d.Install each CS temporarily as planned.

Notes

•Install at least 2 m (6 ft 7 in) above the floor.

•Place the antennas so that they are pointing in directions that are 90 degrees apart (for antenna diversity).

3.Conduct the site survey

Refer to "5 Site Survey".

a.Test the radio signal strength using the PS.

Confirm that the radio signal strength level is "12" near the CS.

Using the KX-TD7685/KX-TD7695

e.Make sure that the radio signal strength level is greater than "3" at any location within the service area required by the user.

4.Finish the site survey

Refer to "6 After Site Survey".

a.Turn off the PS.

b.Stop supplying power, and return all DIP switches of each CS to the OFF position.

5. Connect the CS and PS to the PBX and test the operation

Refer to "7 Connecting a Cell Station to the PBX".

a.Connect the CSs to the PBX.

b.Register the PSs to the PBX.

c.Walk around the service area while having a conversation using a registered PS. If noise is frequent or conversations disconnect, relocate the CSs or install an additional CS.

6. Mount the CS on the wall

Refer to "8 Wall Mounting".

a.If there are no problems in testing, mount the CS on the wall.

3 Site Planning

3 Site Planning

Choosing the best site for the CS requires careful planning and testing of essential areas. The best location may not always be convenient for installation. Read the following information before installing the unit.

Understanding Radio Waves

Characteristics of Radio Waves

The transmission of radio waves and the 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 PS.

The illustration below shows the special transmitting patterns of radio waves.

1.Radio waves are reflected by objects made of materials such as metal.

2.Radio waves are diffracted by objects such as metallic columns.

3.Radio waves penetrate objects made of materials such as glass.

1. Reflection

Column

2. Diffraction

3. Penetration

Relationships between Radio Waves and Building Structure and Materials

•The CS coverage area is affected more by the building materials and their thickness than the number of obstacles.

•Radio waves tend to be reflected or diffracted by conductive objects and rarely penetrate them.

•Radio waves tend to penetrate insulated objects and are rarely reflected by them.

•Radio waves penetrate thin objects more than thick objects.

•The table below shows the transmission tendency of radio waves when they reach objects made from various materials.

Site Survey Preparation

1.Obtain a map and investigate the installation site.

a.Check the obstacles (e.g., shelves, columns, and partitions).

b.Check the materials of the structures (e.g., metal, concrete, and plywood).

c.Check the layout and dimensions of the room, corridor, etc.

d.Write down the above information on the map.

2.Examine the service area required by the user on the map, referring to the following example.

a.Draw the coverage area around a CS. Extend the coverage area 20 m to 50 m (65 ft to 164 ft) in each direction, depending on the materials of the building structures and obstacles in the installation site. Note that a CS cannot be installed outside a building.

b.If 1 CS cannot cover the entire service area, install additional CSs as required. Overlap the coverage areas of adjacent CSs.

Where CS coverage areas overlap, the PS will start call handover to the next CS if the signal from
