EIT Digital, Aalto and Ericsson anounce successful implementation of Narrowband Internet-of-Things prototype

Aalto University, in collaboration with Ericsson Research and EIT Digital, has successfully implemented a prototype for Narrowband Internet of Things (Narrowband-IoT) system, that can be deployed in GSM and LTE spectrum and is tailored for increased coverage, long battery life, low module cost, and large number of devices.

The prototype is a narrowband version of LTE system targeting machine-type communications applications with low data rate that requires low module cost, long battery life time and increased coverage.

Researchers from Aalto University and Ericsson have been developing the Narrowband-IoT system in the context of the EIT Digital ACTIVE High Impact Initiative that is being carried out in Stockholm, Helsinki and Milan and is focused on creating advanced connectivity platform to support application developers from different IoT segments.

Researches have been developing software defined radio implementation of the physical layer of the GSM carrier version of Narrowband-IoT. This is among the first Narrowband-IoT standalone mode implementations and has been done at the same phase as the standardization by 3GPP.

The Narrowband-IoT system was tested in Aalto campus area in Finland to transmit temperature, humidity and air pressure sensor information from a sensor node to the base station. Narrowband-IoT can be deployed on re-farmed GSM carriers, guard bands of LTE spectrum or using part of operator’s LTE spectrum. Aalto has tested the prototype on 630 MHz band, but the system can be easily configured to 900 MHz GSM.

“This opens up for a wealth of applications where IoT systems can utilise standardised Narrowband-IoT communication in extant spectrum readily available and we expect a number of cellular operators taking up this opportunity commercially already next year,” says Henrik Abramowicz, EIT Digital Action line leader for Digital Infrastructure “That is in line with objective of the EIT Digital initiative ACTIVE that develops advanced connectivity platform, which be applied and verified in the health sector and in the transport sector (aircraft and railways) to deliver mobile broadband services as well as support the management of transportation vehicles”.

City of Los Angeles and Philips shine a light on 4G LTE app coverage with Ericsson

Los Angeles is the world’s first city to deploy Philips’ SmartPole street lighting with fully built in 4G LTE wireless technology from Ericsson. The collaboration between Philips and Ericsson delivers on the latest Internet of Things (IoT) innovation and provides a double benefit to LA citizens: high quality, public lighting that is energy efficient, as well as improved network performance in dense urban areas.

“The humble, analog light pole has evolved and we made it happen first, right here in Los Angeles,” said Eric Garcetti, Mayor of Los Angeles. “LA is a world leader in LEDs street lights and has more street lights and poles than any other city in America, with about 6,500 centerline miles of streets. We are now leveraging that previously untapped real estate to give our streets cleaner visibility, better broadband connectivity, and future-ready infrastructure. This implementation, which we’ve only just started, is a prime example of what a focus on smart infrastructure, and creative public-private partnerships can achieve.”

With cellular data traffic expected to grow 9 times by 2020, according to the Ericsson Mobility Report, and current telecoms infrastructure struggling to respond to this demand, Philips SmartPoles are enabling seamless mobile wireless 4G/LTE connectivity, with the small cell technology from Ericsson housed in the poles to enable increased data capacity in the telecoms network. The poles were specifically designed and tested to accept FCC licensed wireless mobile network operator equipment. This enables an alternative deployment methodology of 4G LTE broadband services.

Arun Bansal, Senior Vice President and Head of Business Unit Radio, Ericsson, said: “LA will be a role model for other smart cities that place sustainability and connectivity high on their agenda. As citizens, businesses and industries transform through mobility, cities have an increasingly important role to play as eco-system partners enabling the next wave of innovations that will bring us to 5G in 2020. Innovative solutions like SmartPole and Ericsson Zero Site that efficiently improve the performance of mobile networks will be necessary to address the growing demand from both smartphone users and the Internet of Things.”

For cellular phone operators, this innovation can offer them new possibilities to find the right site location. It also helps scale mobile wireless 4G/LTE infrastructure deployment beyond traditional sites. As a result operators can improve data coverage and capacity for citizens so there are no more signal dropouts.

Amy Huntington, President of Philips Lighting Americas said: “This SmartPole technology proves its role as the backbone of an outdoor Internet of Things platform capable of delivering new services and value and fully supports Mayor Garcetti’s Great Streets program by taking LED street lighting and turning it into a services hub that can adapt to the changing needs of a particular neighborhood over time.”
