27、elaying in wireless meter readout networks. This document is an extension to Part 4 of EN 13757, Wireless meter readout (Radio meter reading for operation in the 868 MHz to 870 MHz SRD band). It supports the routing of mode R2, but the routing of mode S and T is not supported. The main use of this s
28、tandard is to support routed wireless networks for the readout of meters. NOTE Electricity meters are not covered by this standard, as the standardisation of remote readout of electricity meters is a task for IEC/CENELEC. 2 Normative references The following referenced documents are indispensable fo

The specific requirements are to be found in the latter clauses of this European Standard. 4.2 Introduction The availability of low cost radio modules has made it feasible to use radio communi
45、cation for the readout of meter data. Many meters are battery operated and have a very strict power budget and regulatory requirements are imposed as well. This limits the transmitting power levels and thereby the useful distance between transmitters and receivers. The use of reinforced concrete, co
46、nductive surface coatings and placement of meters in the basement of the buildings aggravates the problem of directly communicating between a data collecting unit and a meter. This limits the useful size radio networks unless relaying or forwarding is used. By letting some of the nodes forward or re
47、lay data, the effective size of the network can be increased. This makes the radio based networks a more cost effective solution. A relaying or forwarding concept will still have a number of constraints. The cost of adding this capability to the meters must be low, since meters are cost sensitive hi
48、gh volume products. The limited energy and computing power available in the individual nodes, mandates a limited complexity of the software handling the communications protocol and the forwarding. Operating and installation costs are important factors when planning for meter networks. The reconfigur
49、ation of the network when adding, replacing or removing meters must be automated to limit the operating cost. The overhead due to relaying of data transmitted must be low to keep the transmission duty cycle within the limitations imposed by the authorities. Radio networks for remote readout of meters are basically hiera
