Figure 6.1 depicts the process of planning and creating a GSM/GPRS/EDGE network.
 |
The steps involved in planning a GSM/GPRS/EDGE network are described below. The numbers refer to Figure 6.1.
1. Open an existing radio-planning document or create a new one (1).
- You can open an existing Atoll document by selecting File > Open.
- Creating a new a new Atoll document is explained in Starting an Atoll Project.
2. Configure the network by adding network elements and changing parameters (2).
You can add and modify the following elements of base stations:
- "Creating or Modifying a Site"
- "Creating or Modifying a Transmitter"
You can also add base stations using a base station template (see "Placing a New Station Using a Station Template").
3. Carry out basic coverage predictions (3)
- "Making a Point Analysis to Study the Profile"
- "Studying Signal Level Coverage" and "Signal Level Coverage Predictions"
4. Allocate neighbours, automatically or manually (4).
5. Estimate the required number of TRXs (5) in one of the following ways:
- You can import or create traffic maps (5a) and use them as a basis for dimensioning 5b) (see "Studying Network Capacity").
- You can define them manually either on the TRXs tab of each transmitter’s Properties dialogue or in the Subcells table (see "Modifying a Subcell") (5c).
6. Once you have the required number of TRXs, manually or automatically create a frequency plan (6).
- "Allocating Frequencies and BSICs Manually"
- "Allocating Frequencies, BSICs, HSNs, MALs, and MAIOs".
7. With the frequency plan, make GSM/GPRS/EDGE-specific coverage predictions (7).
- "Analysing Network Quality".
8. Analyse the frequency plan (8).
- "Auditing a GSM/GPRS/EDGE Frequency Plan"
