LTE M2M: Optimizing LTE for the Internet of Things
Nokia white paper
The Internet of Things (IoT) is expected to be the next big thing in the mobile ecosystem, with IoT services being a key driver for further growth in cellular. Numerous services are envisioned for IoT over cellular networks, including utility meters, vending machines and automotive applications. The latter has many categories such as fleet management, smart traffic, real time traffic information to the vehicle, security alerts and reporting, medical metering and alerts. Different connected devices such as E-book readers, GPS navigation devices and digital cameras are already connected to the Internet.
The key requirements for cellular to enable these services and to compete with non-cellular technologies are:
• Support of device volumes
• Low cost connected devices
• Long battery life
• Enhanced coverage
This white paper outlines LTE-based solutions to comply with these requirements through enhancements to the radio network, the core network and the subscription database. The radio network needs to be optimized to enable simple, low cost devices. The transmission and higher layer protocols need to be designed to draw minimum power to enable a more than 10-year battery life and enhanced coverage is required to reach deep indoors and into rural areas. The network elements need to handle charging and subscription without physical Universal Integrated Circuit Card (UICC) cards, as well as admission control and overload in the network, including massive support for small packages.
