Introduction Low Throughput Network (LTN) is
14、 a technology of wide area wireless network with specific characteristics compared to existing radio networks. LTN enables long range data transportation (distances up to 40 km in open field) and has the capacity to communicate with underground equipment, using minimal power consumption. Furthermore
15、, the low throughput transmission combined with advanced signal processing provides effective protection against interference. As a consequence, LTN is particularly well adapted for low throughput machine to machine (M2M) traffic where latency may be low. LTN can be applied to autonomous battery ope
16、rated M2M devices that sends only a few bytes per day, week or month. LTN networks can cooperate with cellular networks addressing use cases where redundancy, complementary or alternative connectivity is suitable. The elements provided in the document are intended to identify potential areas of stan
17、dardization to ensure interoperability and provide guidelines for device, modem and software solutions for vendors, integrators and operators. The document is intended for an audience with a business vision whereas the architecture document GS LTN 002 1 addresses the technical architecture of LTN. C
18、lause 4 describes the LTN network main characteristics and compares LTN with other communications networks (GSM/cellular/PMR), by outlining key differentiators. Clause 5 lists typical use cases with their individual characteristics and associated constraints. Parameters and criteria are described wi
19、th the objective to get an overview of all applicable use cases. Clause 6 describes specific use cases where the usage of LTN brings a significant advantage over regular communication networks. ETSI ETSI GS LTN 001 V1.1.1 (2014-09) 51 Scope The present document aims to: provide an overview of LTN; i
