Foreword This Technical Report (TR) has been produced by ETSI Technical Committee on Electromagnetic com
20、patibility and Radio spectrum Matters (ERM). The present document is part 2 of a multipart deliverable covering Electromagnetic compatibility and Radio spectrum Matters (ERM); System Reference Document; Short Range Devices (SRD), as identified below: Part 1: “Technical characteristics for SRD equipm
21、ent for wireless factory/industrial applications using ultra-wideband technologies“; Part 2: “Technical characteristics for SRD equipment for wireless industrial applications using technologies different from Ultra-Wide Band (UWB)“. Executive Summary Industrial automation requires “robust“ wireless
22、technologies to be used for their critical wireless links in industrial applications. The advantages of wireless are beneath savings of often complex and expensive cables, cable protection and plugs, the increased mobility and flexibility as well as the wear and tear free transmission medium. These
23、advantages are particularly high in the area of: monitoring and mobile worker communication; wireless sensors and actuators at moving parts; setups that require flexility in terms of tool or machine reconfigurations. Different functions can be mastered substantially more efficient by a wireless netw
24、ork of data acquisition terminals, robotic type equipment or automated guided vehicles. For the sensor and actuator type of applications in industrial automation, the main requirement is the real time behaviour: Determinism for process industry. Low latency and determinism for factory automation. Re
25、al time means a maximum response time defined by the type of application. E.g. on the factory floor of discrete manufacturing, very short latencies of a few ms and a very high availability (high robustness) is necessary in order to avoid interruptions in the manufacturing process. In higher levels o
26、f the automation hierarchy e.g. at the control or enterprise level, the data volume rises, so throughput, security and availability becomes more important, but realtime communication requirements decrease. ETSI ETSI TR 102 889-2 V1.1.1 (2011-08)6To meet these requirements, both application categorie
27、s require specific wireless technologies for specialised sensor/actuator networks in combination with specific spectrum for industrial SRDs. Non-critical links can continue to use the existing spectrum for generic SRDs like those listed in clause 6.1. Industrial automation equipment are typically de
28、signed in a way that it is not interfered by other wireless applications present in the industrial environment. If a critical wireless link of an industrial application would be interrupted (interfered), or not respond instantaneously, safety measures beyond communication take effect immediately, ac
29、cording to EN/IEC 61508 i.14 (listed under the Machinery Directive) and EN/IEC 61784-3-series i.15. To achieve the required performances for different industrial wireless applications, it is important to achieve either short latencies or high throughput, in addition to range and availability, etc. T
30、herefore, industrial users very much depend on the chosen technical solutions for their seamless operational procedures, i.e. a high dependability is envisaged. In addition, the manufacturing processes require often to use more than one wireless technology simultaneously within the same area or envi
31、ronment. All the specific needs identified above complicate the selection of frequencies to be used for such applications as availability of the spectrum, and the predictability and efficiency of the communication links is of key importance for the automatic manufacturing process hence why the usual
32、 SRD bands are not adequate for these applications. The intent of the present document is to have spectrum identified and an appropriate regulation developed where these wireless automation devices can operate as intended without being hindered by other applications operating in intensively used SRD
33、 bands. This means that, for the industrial applications, frequency bands different from the 2 400 MHz to 2 483,5 MHz band have to be identified as the usage of an adequate spectrum sharing mechanism to be implemented by the equipment, as mandated by the European Commission for using the 2,4 GHz ban
34、d for power levels above 10 mW, is in conflict with the nature of these applications. For industrial automation, having the same frequency bands available in different countries/regions across the globe is also a very important aspect and an essential requirement, as in todays global economy, machin
35、es or parts of a machine are built and tested (already with a wireless system being part of it) in different countries around the world and then finally assembled in another country. After a model change (e.g. automotive), the production equipment might be sent to yet another country for further pro
36、duction. As explained above, the focus in industrial automation is on achieving robustness, determinism and predictability for the manufacturing processes. However it is understood that, for the industrial applications using critical wireless links, operation in overcrowded bands like the 2,4 GHz ba
37、nd cannot be achieved. This is caused by the mandatory use of adequate spectrum sharing mechanisms to be implemented by the equipment, as mentioned above. So while the non-critical links could use existing spectrum and existing ETSI standards, including the 2,4 GHz up to 2,4835 GHz band, new frequen
38、cies (outside the 2,4 GHz band) need to be identified for the critical links of industrial applications. The preference is to have this new spectrum close to or adjacent to bands which are globally already available and for which industrial wireless technology has already be developed. To address th
39、e specific needs for wireless industrial applications, the following requirements are identified: The use of specific technologies in order to be robust in a dynamic and multi-path environment. Frequency bands (and corresponding requirements according to clauses 6, 7 and 8), which are globally avail
40、able or adjacent to globally available bands as to use existing technology developed for these bands. Frequency bands above 1,5 GHz to avoid interferencefrom welding machines and below 6 GHz due to the quasi optical propagation behaviour above and requirement for non-line-of-sight wireless communica

The present document descri

43、 889-2 V1.1.1 (2011-08)81 Scope The present document describes the technical characteristics and applications specific radio spectrum requirements for SRD equipment in the industrial environment using technologies different from ultra-wide band, which may require a change of the present frequency de
44、signation/utilization within the EU or CEPT. Non-critical wireless links for industrial applications could use existing spectrum regulation and existing ETSI standards, including the 2,4 GHz up to 2,4835 GHz band, however new frequencies (outside the 2,4 GHz band) need to be identified for the criti
45、cal wireless links of industrial applications. The present document includes the necessary information to support the co-operation between ETSI and the ECC including: Market information (see clause 5). Technical information including expected sharing and compatibility issues (see clause 6). Regulato
46、ry issues (see clauses 7 and 8). NOTE: The 2,4 GHz band is not considered within the present document as existing regulations and standards can be used for these applications. 2 References References are either specific (identified by date of publication and/or edition number or version number) or n
