| UNIT 6: MULTI-CELL WIRELESS - LESSON 2: SITE SURVEY Site Survey (continued...) So why do we need to do a Site Survey? Well the Site Survey is the tool used to determine the best possible location for the Cell Station or Stations by providing a constant signal strength throughout the installation site that will provide good quality communications. It is also used to determine the level of performance that you can expect in a given installation location. It also should be used to determine if a Multi-Cell Wireless application can be used at the customer’s location. For example, in some locations, other electronic equipment using the 2.4 GHz frequency band could interfere with the performance of the Multi-Cell Wireless equipment. Or the Multi-Cell Wireless could interfere with the performance the other wireless systems. Examples of other equipment that use the 2.4 GHz frequency band are cordless telephones, wireless LAN’s and microwave ovens. So let’s get into the details of a Site Survey. As mentioned in the introduction, the minimum required equipment for a Site Survey is one Portable Station, either model, one Cell Station, and a Battery Box and Power Supply Adapter, and of course your Site Survey partner. The Battery Box or Power Supply plugs into a DC IN plug on the Power Supply Adapter. Then a standard 4-conductor modular cord is plugged into the TEL jack on the Power Supply Adapter, and the other end is plugged into the TO MAIN UNIT/PABX jack on the KX-T0141 Cell Station. Using a small flathead screwdriver or similar tool, place the Cell Station in the Site Survey mode by moving the 6th DIP switch on the MODE switch on the back of the Cell Station to the ON position. Also move the 1st DIP switch on the MODE switch to the ON position. This sets the Cell Station in the Site Survey mode and designates the station as Cell Station number 1. When you use several Cell Stations during the site survey, each Cell Station must be set with a unique Cell Station number. Refer to page 75 in the Installation Manual for DIP Switch settings. Note: Remember to set all DIP switches back to the OFF position prior to installing the Cell Station at a customer’s location. The Cell Station will not function under normal Multi-Cell conditions if the Cell Station is in the Site Survey mode.
