| UNIT 6: MULTI-CELL WIRELESS - LESSON 2: SITE SURVEY Site Survey Identifying the ideal locations for the Cell Stations can be the most difficult part of a Multi-Cell Wireless application. To make this task easier, the KX-TAW848 Advanced Hybrid Wired/Wireless System provides a special Site Survey mode. The Site Survey mode allows you to test the signal strength between a Portable Station and a Cell Station. A Cell Station can be temporarily placed in a potential installation location, and its performance and coverage area can be determined using a Portable Station. Basically, the purpose of the Site Survey is to provide the largest area of coverage by establishing the best possible location for the Cell Stations so that the signal strength within the installed location is sufficient enough to provide good communications between the Portable Station and the Cell Station. Actually the KX-TAW848 Main Unit is not even needed to perform a Site Survey. You will need at least one Portable Station, a Cell Station, and a Battery Box (requires 8 AA batteries) and Power Supply Adapter. The Battery Box and Power Supply Adapter are used to power the Cell Station without having it connected to a HLC4 extension port of the KX-TAW848. The Battery Box (part # PSZZTD142CE) and Power Supply Adapter (part # PSZZ1TDA0142) can be purchased from the Panasonic Parts Center by calling 800-833-9626, or by going to the Panasonic Parts website. www.pasc.panasonic.com/epartr In place of the Battery Box, a KX-A11 or KX-TCA1 power supply can be used. The KX-A11 power supply is a common power supply used on many Panasonic standard cordless telephones. The KX-TCA1 is the power supply used to charge the Portable Stations. If you choose to use the power supplies over the Battery Box, you will need to have electrical outlets near the location that the Cell Station will be placed during the Site Survey. This may require the need for extension cords and could be somewhat cumbersome in business and residential locations. It is important to note that during normal operation, the Battery Box and Power Supply Adapter are not needed. These items are only needed during the Site Survey. Under normal operating conditions, the Cell Station is powered by the KX-TAW848’s HLC4 port. There is one other item that is recommended during the Site Survey process…actually it is not an item but a person. A coworker or assistant and a method of temporary communications like cellular telephones or walkie-talkies during the Site Survey will be very helpful to efficiently and quickly complete this process.
