Broadcast service site RF Characterisation

LSMC offers its RF antenna measurement services to network operators and regulatory authorities to efficiently determine the on-site performance of complex radiating antennas and without imposing on the actual operation of broadcast services.

The Remote Piloted Aircraft measures the radiation pattern in the horizontal and vertical planes at predetermined altitudes and distances from the antenna. 

The deliverables per transmission service consist of spatially quantified:

• Horizontal radiation patterns (HRP)  
• Vertical radiation patterns (VRP) 
• Effective radiated power (ERP) and 
• Associated derived parameters (mechanical and electrical tilts, null-fill, etc.) .

RF spectrum scans

LS of SA offers a very useful RF scan service in conjunction with its antenna radiation measurements whereby the actual on-site channel utilization in bands of interest is determined. 

Complementary RF spectrum measurements/activities (RPAS)

• Propagation model calibration (diffraction losses, morphology classes refinement,  Fresnel zone obstruction losses)
• Radiation measurements. [E.g.  spectral performance (EMC) of installations/sources]
• Volumetric signal strength measurements within a large three dimensional space. 
• Intermodulation studies/levels and harmonic assessments.
• Noise level studies within a large three dimensional space.
• Identification of “white space” areas.
• Determination of unauthorized transmissions/radiation; Regulatory environment
