Continuous Wave Measurements and Propagation Module Tuning

Al-Hobess has a skilled Engineers & Technicians Teams supported with the required test equipments & tools to perform the Continuous Wave (CW) measurements in different field region sites for Propagation Module Tuning Purpose.

Al-Hobess Teams are capable to perform the below required activities for Continuous Wave measurements:

Sites Survey: to verify the locations of site, space/power availability, reassess the site feasibility, pole locations etc
Sites Selection: select of 10-12 suitable sites covers all clutter types within geographic region of model
Frequency scan: find the cleared frequency channel to used for CW measurement
Route definition: clarify drive routes to avoid street canyons, tunnel and elevated roads.
Test Antenna Installation & equipments setting: measuring the Tx power & VSWR before & after the drive test.
Collecting the RSSI within the coverage area of the selected sites using a calibrated test equipments which are: Signal generator (Transmitter) – Receiver/scanner – Site Master – Power Meter – Omni RX antenna with GPS, RF coaxial cables

Propagation Module Tuning

The aim of Propagation Module Tuning for Mobile Network is to:

Minimise Standard Deviation Error and provide zero mean error
Determine model parameters in accordance to realistic propagation effects existing within proposed regions.
Make sure calibrated model corresponds well with the collected data – data is essential.
Provide cost efficient Nominal Plan

Module Tuning Process / Activities:

Post Processing of the collected data from the CW campaign to average the data over 40λ to have 50 samples which gives one sample every 0.8λ.
Import & display of CW data on Atoll CrossWave SW
Data Filtering and statistical analysis
Data Validation
Generation of propagation model tuning
Model Verification and Acceptance
