In this episode of IoT Talk by emnify, host Gabrielle and Solutions Engineer Brad Herman discuss how to choose the appropriate Radio Access Technology (RAT) for IoT deployments. They explain RAT as the physical connection method for communication networks, highlighting its various types such as Bluetooth, Wi-Fi, GSM, UMTS, LTE, and 5G. Brad emphasizes the need for careful consideration of multiple factors including coverage, bandwidth, power consumption, cost, mobility, indoor/outdoor use, security, and redundancy. They also delve into specific RAT types like 2G, 3G, 4G, LTE, and 5G, and highlight the emerging trends in low-power wide-area networks (LPWAN) like LTE-M and NB-IoT. The episode highlights the importance of thorough preparation, understanding the trade-offs between different RAT types, and ensuring that deployments are future-proof and aligned with technological advancements.
