  • NB IOT( Narrowband Internet of Things ) Narrowband Internet of Things is a Low Power Wide Area Network radio technology standard developed by 3GPP to enable a wide range of cellular devices and services. The specification was frozen in 3GPP Release 13, in June 2016. Other 3GPP IoT technologies include eMTC and EC-GSM-IoT NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow-band of 200kHz. It uses OFDM modulation for downlink communication and SC-FDMA for uplink communications. IoT applications which require more frequent communications will be better served by NB-IoT, which has no duty cycle limitations operating on the licensed spectrum. In March 2019, the Global Mobile Suppliers Association announced that over 100 operators have deployed/launched either NB-IoT or LTE-M networks. This number had risen to 142 deployed/launched networks by September 2019. Devices and modules The 3GPP-compliant LPWA device ecosystem continues to grow. In April 2019, GSA identified 210 devices supporting either Cat-NB1/NB-2 or Cat-M1 – more than double the number in its GAMBoD database at the end of March 2018. This figure had risen a further 50% by September 2019, with a total of 303 devices identified as supporting either Cat-M1, Cat-NB1 (NB-IoT) or Cat-NB2. Of these, 230 devices support Cat-NB1 (including known variants) and 198 devices support Cat-M1 (including known variants). The split of devices (as of September 2019) was 60.4% modules, 25.4% asset trackers, and 5.6% routers, with data loggers, femtocells, smart-home devices, and smart watches, USB modems, and vehicle on-board units (OBUs), making up the balance. In 2018 first NB-IoT data loggers are other certified devices started to appear. For example ThingsLog released their first CE certified single channel NB-IoT data logger on Tindie in the late 2018. To integrate NB-IoT into a maker board for IoT developments, SODAQ, a Dutch IoT hardware and software engineering company, crowdfunded an NB-IoT shield on Kickstarter. They then went on to partner with module manufacturer u-blox to create maker boards with NB-IoT and LTE-M integrated.

    Advantages

    • NB-IoT ultra low power consumption design.
    • NB-IoT Low communication cost.
    • NB-IoT wide indoor coverage area capability.

  • M-Buse Gateway is a general purpose intelligent device for acquiring data from M-Bus Slave devices and pushing the same to server on HTTP Protocol \ FTP. The Terminal support 250 M-Bus Slaves which are connected from a M-Bus Master with output RS232 or TCP/IP . M-Bus master commands can be configured by giving the details like secondary address and FTP Server details, total number of clients, Communication interval, timeout, number of poll attempts etc also can be configured. Once the configurations are made the terminal will be ready to use.

    The terminal will start polling all the configured devices at on the interval specified by the 'Communication Interval'. If the polling is failed the terminal will attempt again and the maximum number of retries will be limited to the 'Number poll Attempts' configured. Once the poll is successful the terminal will immediately send the data to the server using FTP. This process will continue for all the configured devices.

  • When huge amounts of data need to be accessed or processed to any other form of information continuously and if the storage requirements for accumulating these data or information need to be increased, there arises a need for cloud storage. Cloud storage is a service where data can be managed, stored, accessed and remotely maintained. Users will be able to store large files online, so that they can be accessed from anywhere remotely at any time via internet.

    Cloud computing can be defined as the next level of cloud storage where-in information is stored, entails sharing software over a network as a service instead of directly storing a software on a local device.

    Advantages

    • Simplified convenience due to reduced usage of physical spaces like hard-disk drives.
    • Transferring files from local storage to the cloud is both easy and fast since it is possible by mere drag and drop options available in Personal Computer’s (PC).
    • Improved accessibility to files from anywhere, anytime via internet connection
    • Cloud storage can be used as a backup plan since a second copy of files are maintained, makes it useful during an emergency.
    • Improved usage of bandwidth since file transfers through emails can be reduced, instead a web-link can be send to the recipients.
    • Cost-effective and in-expensive process for storing information, reduces the substantial capital cost required for storing data and processed information in any organization and does not require any internal power for storing any of these data.
    • With a well planned service platform, cloud storage is more reliable and manageable.
    • Cloud has unlimited virtual storage space.

    Features

    • Customizable firmware.
    • Real time monitoring of digital inputs.
    • Supports standard protocols like MODBUS, DLMS, HTTP, MQTT and proprietary protocols on RS232 and RS485 ports.
    • Monitors serial ports continuously and captures data for processing and communication to servers on desired protocols.
    • Periodic or event based communication to servers.
    • Server as well as SMS alerts for Digital Input/Digital Output changes.
    • Real time clock with battery back up.
    • Server communication through GPRS.
    • Data storage on SD card or serial flash.
    • Data capture from external devices on standard or proprietary protocols.
    • Configuration via serial port and/or server through SMS.
    • Operates digital outputs in automatic and manual modes.
    • Customizable user logic for digital outputs based on time, weekday, analog input status etc.
