Safe Separation Distances

• Emergency Situations
• Radius of 10m No RF transmission
• Radius of 50m No vehicle-borne sets on transmit
• (eg emergency services)
• Emergency instructions issued to crews of
  vehicles transporting EED

Calculation of Safe Separation Distances

• Calculating transmitter field strength
• Type of aerial (directional or omni-directional)
• Mean power supplied to antenna
• The frequency or frequency band
• The antenna gain
• And if the transmitter has a pulse waveform
• The pulse repetition frequency (pulses per
  second)
• The pulse width in seconds
