SIGFOX is a cellular network technology with city / country-wide coverage that enables remote devices to connect using ultra-narrow band (UNB) technology.
The SIGFOX network and technology is aimed at the low cost machine to machine (M2M) and Internet of Things (IoT) applications where wide area coverage is required.
Wireless M-Bus is the only European standard (norm) for wireless meter reading (EN 13757). The standard was originally developed for communication with battery operated gas, water and heat meters, operating at 868 MHz with a focus on low power consumption and low implementation cost. The standard has later been updated and expanded to include narrowband radio, security (encryption and authentication), and repeater networks. It supports all types of utility meters as well as environmental sensors. Wireless M-Bus is the basis for OMS (Open Metering System) and other national companion standards (France, Italy, Netherlands) for meter reading.
TinyMesh is a powerful multi-hop mesh protocol with bi-directional wireless communication for control and monitoring of individual nodes. The network data packages are 120 byte. The protocol is transparent and may carry other standard application layers such as M-Bus , MODBUS, DLMS/COSEM or KNX.
ZigBee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios.
The technology defined by the ZigBee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs), such as Bluetooth or Wi-Fi. Applications include wireless light switches, electrical meters with in-home-displays, traffic management systems, and other consumer and industrial equipment that requires short-range low-rate wireless data transfer.
Radiocrafts’ protocol RC232 is designed to enable a simple and effective cable replacement when using ISM band radio modules for transmission of data. The RC232 protocol is embedded in the module and enables star (point-to-multipoint), point-to-point networks, and a multi-hop option. The RC232 modules can be controlled with a simple-to-use UART interface, and used to configure the protocol for the actual application.
The standard is based on the communication stack of EIB but enlarged with the physical layers, configuration modes and application experience of BatiBUS and EHS. KNX defines several physical communication media, such as Twisted Pair wiring (inherited from the BatiBUS and EIB Instabus standards); powerline networking (inherited from EIB and EHS – similar to that used by X10); radio (KNX-RF); Infrared; Ethernet (also known as EIBnet/IP or KNXnet/IP).
KNX is designed to be independent of any particular hardware platform. The most common installation is using twisted pair as medium
The traditional installations used twisted pair, but the new KNX RF Multi provides a reliable wireless alternative that simplify the installation and reduce cost. The “Multi” protocol adds frequency agility and link layer acknowledge/retransmission, hence ensuring communication reliability.
