Cyber Security Radio Location

Geo location:
Geographic location of object such as radar, mobile phone or Internet connected computer terminal.

 Radio location:
Radio location is a technique used to find the location through radio waves in certain geographical area.

 Radio location techniques:

  • Recieved signal strength (RSSI)
  • Time of arrival (TOA)
  • Time difference of arrival (TDOA)
  • Angle of arrival (AOA)

RSSI:Recieved Signal Strength:
  • Recieved signal strength is used to measure the distance at which signal received.
  • Received signal strength can be influenced by weather, terrain and antenna.

 TOA:Time of Arrival:
  • Time of arrival is time of transmission and speed of propagation are known as TOA.
  • Clock skew at fast RF speeds, amplifiers, errors.

 TDOA:Time Difference of Arrival:
  • Time difference of arrival is a combined TOA data from several receivers is known as TDOA.
  • Multiple clock skew faster RF speeds, amplifiers, errors.

 AOA:Angle of Arrival:
  • Angle of arrival is determined by the use of directional antenna by correct way.
  • AOA can be easily influenced by antenna design and other factors.
