field communication method making it difficult 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 verification of data .
Quality of Service (QoS): QoS for the FreeStyle Libre Pro Reader and Sensor wireless
communications using the near field communications is assured within the effective range
of 4 cm between the Sensor and Reader that is specified to occur within 15 seconds .
