2 Scope of Work
The client has contracted EnVision Wireless for RF drive testing services. The following sections detail the project requirements and deliverables for this drive test survey.
2.1 Project Requirements
§ Passive RF measurements (RSL) will be recorded on the client’s network around multiple search rings.
§ Scanner and phone measurements will be recorded. § EnVision will provide one drive test team and equipment necessary to complete the
project. § EnVision will post process the data and generate coverage plots. § The client will provide a list of channels to be included in the scan lists for each search
ring. § The client will provide the search rings and/or drive test areas to be surveyed.
2.2 Deliverables
EnVision understands the client’s goal is to characterize the best server from their network in the drive test areas. The deliverables for this project are as follows: § RF coverage plots (strongest server) for each of the search rings measured. One plot
will be based on the data from the scanning receiver and one plot from the handset. Display bands have been specified by the client.
§ A CD containing the raw measured data collected by the drive test team.
2.3 Complimentary Deliverables
Additional services are being provided to the client at no additional charge. The following additional information is included in this report: § Overall network call statistics: Ø Completed Calls Ø Blocked Calls Ø Dropped Calls Ø No Services Calls
§ Svr SQE profile (distribution graph) § Svr SQE geographic plot

3 RF Coverage Measurements
The following sections describe the equipment, configuration and methodology used during data collection phase of this project. Geographical coverage plots of the strongest server (scanner and mobile phone) are provided in section 3.3. To maintain detail, overall data was divided geographically (North and South) and mapped.
3.1 Measurement Technique
Agilent Portable Voiceprint equipment was configured with a DTI iDEN Seagull scanner to record continuous channel measurements. The channels, provided by the client, were scanned at a rate of 260 channels per second and recorded using Agilent Nitro software. Mobile phone metrics (Svr Power) were recorded using Agilent Portable Voiceprint equipment. Data was collected continuously during periods of idle and TI Encode call status. Null gain external antennas were used for both the scanner and mobile phone devices.
3.2 Call Placement
The following details the call placement requirements for this project: § The network testing was performed during the weekdays and between the hours of
7:00 AM and 9:00 PM. § A Motorola r370xl handset was used to place calls from within the drive test vehicle
(in-vehicle portable using an null gain external antenna configuration). § Calls were placed on the client’s network with a call duration of 90 seconds (typical
average call length) with an idle time of 20 seconds between calls.
3.3 Area and Road Selection
The following details the area and road selection requirements for this project: § Approximately 575 miles were driven over 3 days. § Area drive routes were selected by the client.

4 Performance Measurements
This section discusses the technology measured, call classifications and the performance evaluation for this data collection project. Performance call statistics (graphical and tabular) are displayed in sections 4.3.1 and 4.3.2. A Cumulative SQE profile is shown in section 4.3.3 with a graphical presentation of Svr SQE in section 4.3.4.
4.1 Technology Measured
One network was evaluated for this survey. The carrier, technology and handset used for the measurements are shown in the following table as a reference.

Client iDEN Motorola r370 xl
4.2 Call Classification
The following call classification definitions apply to all measurements presented in this report: § NO SERVICE - If the phone is out of the service area, the call is classified as no service.
In other words, the call is not completed due to a lack of synchronization on the control channel.
§ BLOCKED - A blocked call attempt has no voice channel assigned within the call setup
interval (typically 20 seconds). This includes calls being disconnected at the PSTN. § DROPPED - If the call ends prematurely after a voice channel has been assigned, the
call is classified as a dropped call. § COMPLETED - If the call ends correctly at the end of the specified call the call is
classified as a completed call. Although the call is classified as completed or good, this is considered the minimum standard of operation and is no indication of the user-perceived quality.
