The role of National Regulatory Authorities: human exposure, threat or opportunity?

  • Limited information may cause citizens to worry and complain.
  • Mayors are facing a dilemma: digital growth vs. citizen protection.
  • Although they have limited legal rights to prevent the rollout of base stations, mayors can influence through their local connections.

Worries about human exposure may hamper the development of broadband communications.

Regulator can play the key role of trusted party:

1.Gather technical information from operators;

2.Disclose information publicly;

3.Perform simulation and check potential issue with measurements;

4.Propose remediation technics and discuss implementation with operators;

5.Make your results publicly available;

6.Organize national discussions and issue guidelines.

Human exposure is actually an opportunity to get increased recognition for your public utility, from both general public and politicians.

 

Field Strength exposure – Inputs required for simulation with ICS telecom:

High resolution cartographic dataset including:

-Digital Terrain Model (DTM) describing the ground altitude of each point

-Building layer describing the contour and the height of each building

-In raster format

-If possible in vector format (SHP for example) (***)

-Image form WMS servers (Bing, Google, …)

-Address database coming from Bing servers

VectorIsomet

  • Import all transmitting stations on the map operating in the different bands for all services:
  • Mobile (2G, 3G, 4G)
  • Broadcast FM, TV (analogue and digital)
  • TETRA
  • With location and technical parameters:
  • Location
  • Frequency
  • Radiated power
  • Antenna patterns
  • Azimuth and tilt
  • Antenna height

Field Strength exposure – 3D coverage calculations:

  • Power sum of all signals received
  • Quadratic power sum
  • ECC 1999 method
  • On building facades
  • and/or
  • Outdoor / Indoor
  • In LOS / NLOS mode
  • From street to building rooftop

Field Strength exposure – Graphical analysis of Hot points:

On a given point (address) Information about:

  • Signals Received
  • Level where each signal is received
  • Station ID producing each signal

FS3D

Hot points can be located on the 2D view as well

Field Strength exposure – Address reporting:

Hot points are automatically reported

Reports

 

Field Strength exposure – Public access:

  • Locations with field strength greater than a given value can be published online
  • Transmitting sites can be located on the map including field strength on buildings
  • Thanks to a geo-reverse location engine, people can get information about exposure level
  • Protected sites can be located on the map (schools, hospitals…)
  • Web portal can be fully customized on demand
