1st step towards improvements in optimizing current network performances includes Drive Testing Data Collection Services and Data Post-Processing Services. Drive Testing is conducted for a variety of purposes and can occur at several stages during a project. Where requested, this service also includes processing of the data into a format that can be directly used for analysis (i.e. creation of plots, etc.).

mPraxis team can perform:
Cluster Optimization Drive Testing: When all sites in a cluster or system are on-air with all significant issues resolved, multiple rounds of optimization drive testing will be performed along drive routes mutually agreed upon. A test round is defined as drive testing the cluster/system and collecting forward link (base station to mobile) information and then making appropriate network changes based on the results. A re-drive of drive routes is performed to verify that all recommended changes have been implemented and that the desired network performanceimprovement is realized without creating undesirable affects. If the desired network performance is not achieved, it is necessary to implement additional changes and re-drive the cluster until the required performance is achieved through troubleshooting and optimization efforts.

Data Drive Testing: Data Drive Testing will employ data sessions including FTP, Internet/Intranet access and basic data transfer modes of TCP/IP network testing. The network data rate goals will be established by market requirements and design. The Drive Team would drive specific locations throughout the network where they will send and receive data to establish the network’s data performance. In some instances Mobile Data Drive Testing will be required, in which Drive Teams will follow pre-determined drive routes while sending and receiving data.

Benchmarking: Data on up to five operators will be collected for multiple technologies that may include CDMA, TDMA, IDEN and GSM/GPRS. The benchmark drives will be completed using a constant vehicle speed at an average of 30 to 55 miles per hour depending on the area. Test calls will be established as “mobile to land” using 90 (or specified) second long calls, and re-originations will occur within 30 (or specified) seconds. The tests will also include collection of fast scanner data on specified channels.

RF audits including:
  • Checking all antennas at each location
  • Checking all cables and connections for weathering and tightness
  • Checking azimuth, center line, down tilt (electrical and mechanical) Antenna Centerline and coordinates.
  • Verifying that the RF implementation matches the RF Design Sheet.
  • Modifying RF Data sheets with correct coordinates and antenna centerline
  • Readjusting down tilts if incorrect.
Network audits:
  • Network Audit Report
  • Network / Site diagram
  • Peripheral Equipment Layout
  • Equipment/Asset Inventory Report
  • Excess Capacity Report
  • DSX, MDF, and FDF Validation
  • Hardware and Software release Documentation
  • Leased Circuit Documentation Network Optimization Studies and
  • Redeployment and Implementation Plan
