The primary focus is to use the Short Range Devices (SRD) u
21、nlicensed telemetry band, 868 MHz to 870 MHz. The standard encompasses systems for walk-by, drive-by and fixed installations. As a broad definition, this European Standard can be applied to various application layers. 2 Normative references The following referenced documents are indispensable for th

28、es between 9 kHz and 40 GHz 3 General 3.1 Introduction The “Meters“ may communicate with “Other“ system components, for example mobile readout devices, stationary receivers, data collectors or system network components. For the meter side, it is assumed that the communication function will work with
29、out any operators intervention or need for battery replacement over the full lifetime of the radio part of the meter. Other components such as the mobile readout or stationary equipment may have a shorter battery lifetime or require an external power supply as dictated by the technical parameters an
30、d use.

Many of the physical and link layer parameters of these different modes of this
31、 document are identical, allowing the use of common hardware and software. However, due to the operational and technical requirements of these modes some parameters will differ. a) “Stationary mode“, mode S is intended for unidirectional or bi-directional communications between stationary or mobile
32、devices. A special transmit only sub-mode S1 could be optimised for stationary battery operated devices with a long header and the sub-mode S1-m is specialised for mobile receivers. b) “Frequent transmit mode“, mode T. In this mode, the meter transmits a very short frame (typically 2 ms to 5 ms) eve
33、ry few seconds thus allowing walk-by and/or drive-by readout. Transmit only sub-mode T1. It is the minimal transmission of a meter ID plus a readout value, which is sent periodically or stochastically. The bi-directional sub-mode T2 transmits frequently a short frame containing at least its ID and t
34、hen waits for a very short period after each transmission for the reception of an acknowledge. Reception of an acknowledge will open a bi-directional communication channel. c) “Frequent receive mode“, mode R2. In this mode, the meter listens every few seconds for the reception of a wakeup message fr
35、om a mobile transceiver. After receiving such a wakeup, the device will prepare for a few seconds of communication dialog with the initiating transceiver. In this mode a “multi-channel receive mode” allows the simultaneous readout of several meters, each one operating on a different frequency channe
36、l. Meters or other communication devices may support one, multiple or all of the described modes. 3.2 Meter communications types The following Table describes the key features of each mode and sub-mode.

For the user, an important parameter is the radiated sensitivity, that could be estimated by combining the conducted sensitivity and the antenna gain. b If the conducted mode is not possible
43、, the sensitivity shall be measured by sending a signal with a known field strength to the receiver, according to 4.2 of EN 300 220-2, V1.3.1:2000. The radiated sensitivity could then be measured via the block acceptance rate. c The antenna gain shall be stated by the manufacturer. Licensed Copy: sh

47、 a unique User/Manufacturer ID of the meter. The 15 least significant bits of these two bytes shall be formed from a three letter ISO 646 code (AZ) as specified in EN 13757-3:2004, 5.5.

If the most significant bit of this two-byte User/Manufacturer ID is different from zero, then the 6-byte address shall be unique at least within the maximum transmission range of the system (soft address).
