Making sMart use of nB-iot
t
he internet of things (iot) is revolutionising the way we work and play, as industry is rapidly recognising the business benefits
and increased revenue opportunities that connected intelligent devices will deliver. according to Meticulous research, the industrial iot (iiot) market will reach $263.4 Billion by 2027, and has already been adopted across several industry sectors, including manufacturing, logistics, oil & gas, transportation, energy/utilities, mining and metals, and aviation. narrowBand iot (nB-iot) facilitates iiot and
enhances manufacturing by enabling smart processes and has been standardised by the 3rd generation Partnership Project (3gPP), by merging Huawei’s cellular iot (nB-ciot) technology and nokia, ericsson and intel’s nB-Lte technology. nB-iot is used for indoor coverage and is
deployed in-band within the Long term evolution (Lte) spectrum, enabling many devices to connect at low cost, while optimising battery life. Lte is a prevailing force in the licensed spectrum, with Lte services for iot having been deployed by most carriers, alongside the increased production of Lte chipsets. in industry, the number of cellular iot connections enabled by nB-iot and Lte for Machines (Lte- M) continues to grow. using a Low Power Wide area network
(LPWan), nB-iot enables multiple devices and services, that require small amounts of data over long periods, to be connected securely using cellular bands at low cost and low power. specifically designed for machine communications, nB-iot bridges the gap between mobile comms technologies and short- range wireless technologies, such as Bluetooth and Wi-fi. this means that an eLte or nB-iot
Successful Internet of Things (IoT) implementation necessitates a technology paradigm shift. With multiple devices, machines and other components continually ‘talking’ to each other as part of the IoT connected world, the question for technology developers is how to effectively deal with noise on the radio spectrum in order to deliver streamlined IoT communications. Focused on Industry 4.0 applications, NarrowBand IoT (NB-IoT) enables a vast number of multiple machines, devices and services to connect at low cost, while optimising battery life. Here, Phil Evans, business line manager for Telecoms at TÜV SÜD, discusses a smarter approach to join the NB-IoT wave.
chip can be added to the manufacturing terminal, so that the chip can transmit data generated by the terminal via the eLte or nB- iot network, thus enabling manufacturing data to be collected and commands issued. as it requires only 200kH of bandwidth and is less susceptible to interference than other
unlicensed spectrum LPWa solutions, nB-iot can easily run adjacent to existing cellular networks in the manufacturing environment. also, as it operates in the licensed spectrum, it benefits from all the security and privacy features of mobile networks, such as support for user identity confidentiality, entity authentication,
