Close Contact Proximity (5-10 feet)
Close contact proximity event logging for studies of disease transmission and social interaction.
The detection range can be defined down to 5 feet.
NOTE: The actual range of proximity signals is determined by many factors other than transmitter’s power, receiver’s sensitivity, and frequency range used. They can be: transmitter’s and receiver’s antenna elevation above the ground – which are dependent on species under study, animal’s neck size – which determines antenna length and type, terrain, vegetation, etc. It is possible, especially while studying small animals, that what we call far proximity exhibits range of a few tens of feet only.
