Introduction

Clutter Data is used to determine interference to the electromagnetic spectrum, from transmitter to receiver.

Whether you are a telecom or media company, or a service provider to these groups, clutter data is becoming vital for operation purposes.  Ensuring your telecommunications are free of interference is critical to ensuring your customers are receiving the best possible reception whether that is by phone, tv or radio.  Understanding clutter data can improve your business.

This interference, comes in many forms, and interacts with the mid to upper radio frequency section of the spectrum, in three main ways:

Deflection is the result of the electromagnetic wave encountering obstructions with much larger dimensions than the wavelength of the radio wave. This results in the wave rebounding.

Diffraction occurs when radio waves encounter the edges and corners of obstacles. These act as secondary sources re-radiating beyond what is known as line-of-sight into the shadow region of the obstacle. Diffraction allows RF energy to travel in dense urban environments where there is no clear line-of-sight between the transmitter and receiver antenna.

Diffusion (Scattering) occurs when the dimensions of the object (usually vegetation) interacting with the radio wave are similar to the impinging wave’s wavelength. This causes the signal to disperse.

Advantages:

For Wireless Telecommunications:

• Enhance service coverage and reduce dropped calls
• Predict the performance of wireless services in transmission areas
• Plan the build or redesign of their network
• Optimise transmission site locations and reduce infrastructure costs

For AM/FM Commercial Radio Stations:

• Accurate potential audience prediction
• Radio Signal Coverage, Shadow Prediction
• Better reception for mobile Listeners, e.g. car, Walkman.

Radio Communication:

• Reliable communication within an urban environment.
• Reduced number of repeaters
• Reduced power output where unnecessary

Wireless Network (Internet):

• Reduced number of access points –leasing, maintenance.
• Higher speed connections
• Reliable High speed ‘roaming’ connection within high-density urban areas.

General EMS User Advantages Of An Accurate Radio Coverage Model

• Accurate User/Listener Population
• More efficient placement of access points, relay stations, base stations.
  • Reduced Power Output or increased coverage for same power output
  • Reduced lease, maintenance, and insurance, electricity costs.
  • Accurate radio shadow prediction
  • Reduce Unnecessary Radiation
• Reliable signal reception
