- 2. Networking technologies: Low-power WAN (LPWAN) It is a wireless wide area network technology that interconnects low-bandwidth, battery-powered devices with low bit rates over long ranges. Created for machine-to-machine (M2M) and internet of things (IoT) networks, LPWANs operate at a lower cost with greater power efficiency than traditional mobile networks. LPWANs can use licensed or unlicensed frequencies and include proprietary or open standard options. The proprietary, unlicensed Sigfox is one of the most widely deployed LPWANs today. Running over a public network in the 868 MHz or 902 MHz bands, the ultra- narrowband technology only allows a single operator per country.
- 4. Features of Low power wide area Network. LPWAN provides long range communication It has less bit rate LPWAN devices has low power consumption Offers better connectivity. Applications : Environment monitoring.
- 5. Widely Used LPWAN technologies LoRa Sigfox NB-IoT Cat-M1
- 6. LoRa The LoRa WAN is a Long range,low power wide area open access protocol designed for long distance communication. The Protocol is defined by LoRa Alliance Cloud based MAC layer protocol which manages communication between LPWAN gateways and end node devices.
- 9. Sigfox: Sigfox is an LPWAN technology that offers end to end IoT connectivity. Sigfox deploys its proprietary based stations connected to back end servers. End devices are connected to base stations using BPSK modulation. It uses bandwidth very efficiently Very Low noise Levels Low power consumption High receiver Sensitivity
- 10. NB-IOT: It is Narrow Band IoT technology released by 3GPP in 2016. Uses licensed frequency bands of 700 MHz , 800MHz and 900MHz. It allows connectivity of upto 200k end devices per cell. Uses FDMA technique and QPSK Modulation Consumes large power compared to Sigfox and LoRa
- 11. Cat-M1 Cat-M1 is a LPWAN technology which supports high data rates. It operates at 1.4 MHz bandwidth Higher device complexity/cost than NB-IoT Cat-M1 uses OFDM modulation technique Wider bandwidth allows data rates upto 1 Mbps Provides very accurate device positioning capabilities Supports voice calls and mobility of devices, Used in wearable devices, smart vehicles. Trackers etc.
- 12. Comparison of LoRa, Sigfox, NB-IoT, Cat-M1
- 13. Cross Connectivity across IoT System Components IoT connectivity is a term defining connection between the all the points in IoT ecosystem The core modules of IoT system are: o Sensors o End-Points o Analytics o Data Management o Data Communication Protocols
- 14. IOT Gateway Programmed hardware devices which form the communication bridge for different technologies Creates bridge between the Iot sensors / actuators and the Internet IoT gateway aggregates all data, translates sensor’s protocol, and pre process the data before sending it.
