Exploring LTE LPWA IoT
- Course Length:
- 2 Days Instructor Led
Internet of Things (IoT) is expected to dominate telecom market in the coming years where machines exchange data for intelligent applications. Devices and networks supporting IoT pose unique challenges such as low power, low cost, low mobility, and long battery life. This advanced course on LPWA IoT takes a detailed look at 3GPP’s efficient IoT solutions involving UE Category M1 and UE Category NB1. The network architecture enhancements required for IoT such as NIDD and SCEF are described. The roles played by IoT-specific protocols such as MQTT-SN, FOTA/SOTA, and DoNAS are summarized. A brief overview of the UE module industry is given. The architecture of a UE is discussed. Wireless optimizations customized for IoT are explained. Key technical features of EC-GSM are described. Characteristics and operations of UE categories M1 and NB1 and the network in support of IoT are illustrated.
Technical personnel working for wireless operators, equipment and device manufacturers, who need a detailed look at 3GPP’s IoT solutions.
