Any network that is built to communicate is based on certain standards that are defined by a body that governs the rules of communication. This is mainly to ensure different vendors and service providers can communicate their devices with ease and to avoid monopoly and too much dependency on a particular brand or service provider free test kit. For m2m communication that main institute that governs is the European Telecommunication Standards Institute (ETSI). They have come up with many Technical Reports and Technical Specifications in last few years for Equipment Manufacturers and developers to follow. This helps in building a homogeneous network.
