EnVision Wireless, Inc. Confidential - 1 - 4/11/2003

1 Introduction

EnVision Wireless is an RF engineering firm that specializes in the design, optimization and testing of today’s wireless communication networks. Our engineering staff has experience in implementing networks based on all major wireless technologies including CDMA, GSM, iDEN and TDMA as well as the newer 3G technologies of CDMA2000 and UMTS. As an Agilent Authorized Services Provider (ASP), EnVision has been trained and certified in the use of Agilent’s engineering processes as well as their wireless products including Wizard, Nitro, Portable Voiceprint and OPAS32. Participation in this program provides EnVision with unprecedented access to the most advanced test and measurement tools available for the engineering of today’s wireless networks. The end result – EnVision can offer more advanced and efficient solutions to its clients at very competitive prices. The following is a list of the services we provide: § Wi-Fi design, testing and installation § Wizard propagation model optimization § Data analysis and post processing § Radio network design § Network optimization § Traffic planning § Frequency planning § Site validation § Search area map creation § Zoning support § On-site consulting § Training § Network benchmarking § Project management § Fixed network design § Facilities coordination

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.

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.
