Scalability Analysis of LoRa and Sigfox in Congested Environment and Calculation of Optimum Number of Nodes.

Low-power wide area network (LPWAN) technologies as part of IoT are gaining a lot of attention as they provide affordable communication over large areas. LoRa and Sigfox as part of LPWAN have emerged as highly effective and promising non-3GPP unlicensed band IoT technologies while challenging the supremacy of cellular technologies for machine-to-machine-(M2M)-based use cases. This paper presents the design goals of LoRa and Sigfox while throwing light on their suitability in congested environments.

Private Doctors' Perspective towards "Patient First" in TB Diagnostic Cascade, Hisar, India.

TB diagnosis has been simplified in India following advances in available diagnostic tools. This facilitates private doctors' "patient first" approach toward early diagnosis; however, costs remain high. India's NTEP established a TB diagnostic network, which is free for patients and incentivizes private doctors to participate.
