Intellectual Property Rights
Essential patents
IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no
right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does
not constitute an endorsement by ETSI of products, services or organizations associated with those trademarks.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical 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 Rules (Verbal forms for the expression of

1 Scope
The Internet of Things (IoT) presents a wide and growing range of communications requirements. Certain of these
requirements are addressed by systems which are referred to as 'Low Throughput Networks' (LTN) in ETSI documents.
The use cases addressed by LTN systems and the LTN systems characteristics are provided in ETSI TR 103 249 [i.1].
LTN systems may be considered to be a subset of Low Power Wide Area Networks (LPWAN), that may include other
systems, already existing or developed in the future.
The present document specifies the architecture of LTN systems. It contains requirements and/or recommendations on
functional blocks and interfaces that are related to the architecture (i.e. high-level description) of LTN systems.
The present document develops the work done in LTN ISG [i.2] on architecture for LTN systems.
The present document should be read in conjunction with the LTN document [i.1] and related documents, in which
details of entities and interfaces are documented.
