Project Explorer •
•
The Project Explorer is present whenever a project is open, and is initially docked at the left side of the application window. Drag the Project Explorer to the left side of the screen to once again dock it on the left side of the application window. When docked, only the width of the Project Explorer is resizable. If you want to hide the Project Explorer from view, choose View ➤ Hide Project Explorer. Choose View ➤ Show Project Explorer to once again view the Project Explorer.

Interference Matrix Generator •
An interference matrix compares sector signal strengths throughout the network and identifies the sectors that potentially interfere with each other. Sectors with similar signal strengths produce interference when they are on the same or adjacent channels. An interference matrix can be based on any or all of the following: ■ a network analysis ■ a traffic map ■ network data ■ local RF engineering knowledge For all projects, an interference matrix is used for creating neighbor lists. It is also used as an input to other tools such as the Automatic Frequency Planning tool, the Interactive Frequency Planning tool, and the Color Code Planning tool.
Neighbor List Generator •
• • • •
Each sector in a wireless network coordinates with its neighbors to maintain good quality coverage to mobile users. As a mobile user reaches the margins of coverage within a sector, stronger signals become available from other sectors. Through a process called handover, the network re-routes the user’s call to one of the neighbor sectors to maintain the connection. Neighbor relationships affect frequency planning, because neighbor sectors cannot use the same frequencies. If sectors have more neighbors than are required for reliable service, the result can be an inefficient use of the available spectrum. You can create a list of neighboring sectors within a single-technology network or within a multitechnology (W-CDMA and GSM) network. Single- technology neighbor lists can be based on a best server layer, an interference matrix, or from actual network data, while multi-technology neighbor lists can only be based on a best server layer. – – –

Import/Export Wizard •
•
•
import and export project data using Microsoft Excel spreadsheets, contains site, sector, and other project settings divided into different worksheets. When you export data to an Excel file, individual worksheets are created foreach category of project data. In addition, a Summary worksheet is created that displays: ■ the name of the project ■ the name of the application ■ the application version ■ the site and sector coordinate systems ■ the decimal separator By default, when you export data, the site coordinates are saved in the Longitude/Latitude (WGS 84) projection.
Importing Survey Data •
• •
Surveying involves collecting signal strength values at small intervals, including many samples from all clutter classes wherever possible. For best results, the raw data collected must be modified to filter unrepresentative points and average duplicate points. Using Planet EV, you can work with and analyze survey data. Survey data can greatly increase the accuracy of predictions. When you add or import survey data, it is added to the Survey Data node in the Project Explorer under one of the following categories: ■ Surveys RSSI—contains surveys with valid antenna information ■ Surveys Delta—contains surveys that measure differences, such as those you create when comparing surveys ■ Surveys Other—contains surveys with data other than RSSI values
* RSSI (Received Signal Strength Indicator) is the received power within the relevant channel bandwidth. Measured at the equipment antenna connector
Data Manager • • • • •
Data Manager enables you to share Planet EV projects in a multi-user environment. You can work with and share data efficiently and securely in a multi-user environment using Planet EV. Sharing data in Planet EV involves two distinct elements: ■ Data Manager, – – – – – –
