Abstract

Recommendation ITU-T G.9959 specifies the physical (PHY), medium access control (MAC),
segmentation and reassembly (SAR), and logical link control (LLC) layers for short range
narrow-band digital radiocommunication transceivers (TRXs). This Recommendation contains the
non-radio (frequency) related aspects of the radiocommunication TRX. Sub 1 GHz TRXs claiming
compliance with this specification shall also comply with Annex A of this Recommendation.
