46、Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rule

47、s (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI TS 103 357 V1.1.1 (2018-06)101 Scope The present document specifies the radio protocols of three radio technologies, referred to as “families“.

48、 It contains an implementable description of physical and MAC/link protocol layers. It concludes with a section on implementation commonalities between the three LTN families. NOTE 1: ETSI TR 103 249 i.8 describes LTN use cases and system characteristics. NOTE 2: ETSI TS 103 358 i.9 specifies the ar

49、chitecture of LTN systems. NOTE 3: Based on the above documents, radio technologies have been developed with a focus on different subsets of applications, where the optimal balance of technical parameters differs. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
