  1. 21. Fire detector sensor nodes using Long Range (LoRa) radio communication : Branddetektorsensorer som använder Long Range (LoRa)

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Roney Yelda; [2023]
    Keywords : ;

    Abstract : Fire can be fatal, burning homes and forests and its emissions can pollute the air. To prevent these types of catastrophes, it will be necessary to develop a sensor module capable of detecting and alerting humans by sending a signal via a network called The Things Network (TTN).

  3. 22. Digital Front End Algorithms for Sub-Band Full Duplex

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  4. 23. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27

    University essay from Umeå universitet/Institutionen för fysik

    Author : Oskar Hellström; [2023]
    Keywords : ;

    Abstract : Base stations (BSs) are the cornerstone that enables wireless communications. In order for a new BS variant to be imported and sold in the US they are required to undergo electromagnetic compatibility (EMC) testing. This testing is necessary to obtain their Federal Communications Commission (FCC) certification. READ MORE

  5. 24. The Evolvement of the Wireless Industry Capability for Agile Service Production

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Gustav Curan; [2023]
    Keywords : 5G; Software-defined networking; SDN; Programming;

    Abstract : Along with the dramatic changes that have happened over the years, from the first-generation (1G) of mobile networks to the current fifth-generation (5G) of mobile networks. A wide range of different technologies has been seen as potential possibilities for changing and improving the 5G networks, whereas Software-defined networking (SDN) has been widely regarded as one of the significant enablers for this possibility.

  6. 25. LoRa Radio Performance Analysis Based on AVR-RSS2 and RIOT-OS for Indoor IoT Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : HongShuo Yi; Duosi Dai; [2023]
    Keywords : LoRa; Indoor IoT Internet of Things ; Signal strength; Round-trip time RTT ; Goodput; LoRaWAN device classes; AVR-RSS2; RIOT-OS; LoRa; Inomhus-IoT Internet of Things ; Signalstyrka; Rundresa-tid RTT ; Goodput; LoRaWAN klasser; AVR-RSS2; RIOT-OS;

    Abstract : This thesis is dedicated to measuring the communication performance of LoRa technology in an indoor environment and providing insight into its potential application as an effective Internet of Things (IoT) communication solution in Low Power Wide Area Networks (LPWAN). Through careful experimentation and analysis, we assessed various transmission parameters such as spreading factor (SF), bandwidth (BW), Payload Length (PL), and LoRaWAN classes. READ MORE
