AT&T is working with Ericsson to deploy CAT-M and NB-IoT 3GPP standards-based technologies, while Singtel is to work with Ericsson on readying its network for NB-IoT.
Both CAT-M and NB-IoT are variants of 4G LTE designed to enable low power wide area networks for IoT applications using 4G spectrum in a much more efficient way than the current standard allows.
Ericsson will deploy these advanced network technologies for AT&T to support the millions of Internet of Things (IoT) devices and services coming to market:
- CAT-M technology supports next generation devices like wearables and utility meters.
- Narrow-band IoT (NB-IoT) supports next generation devices like smoke detectors, pollution monitors and industrial/agricultural sensors.
- Power-saving mode and Extended DRX extend battery life of enabled IoT devices, letting them communicate in the field for up to 10 years, or more.
AT&T and Ericsson displayed these technologies at Mobile World Congress in Barcelona and expect to begin trials later this year.
Singtel partners with Ericsson
AT MWC 2016, Singtel and Ericsson announced their partnership to ready Singtel's 4G LTE network to support the expected rapid growth of connected devices in Singapore (pictured). The collaboration will start with a trial of Narrowband Internet of Things (NB-IoT) technology beginning in the second half of 2016.
NB-IoT is a solution which will enable extended coverage and much less complex devices transmitting very small amounts of data to be supported on LTE networks. It will enable Singtel to support new IoT use cases in areas such as smart cities, utilities and the environment. Singtel's 4G LTE network already supports low-cost Category 1 (Cat-1) devices, which are built for IoT applications.
