* Security measures: The communication between Reader and Sensor is a short range near
eld communication method making it dicult to interfere with or intercept data that is
being transferred. The Sensor and Reader are protected by proprietary data format, memory
mapping, and cyclic redundancy check (CRC) generation and verication of data.
Quality of Service (QoS): QoS for the FreeStyle Libre Reader and Sensor wireless
communications using the near eld communications is assured within the eective range
of 4 cm between the Sensor and Reader that is specied to occur within 15 seconds.
