Ericsson and Orange have announced a trial of optimised, low-cost, low-complexity devices and enhanced network capabilities for Cellular IoT over GSM and LTE.
IoT is a rapidly growing segment and, according to the Ericsson Mobility Report, there will be 28 billion connected devices by 2021. Cellular is a great foundation for IoT uptake given its advantages of global reach, reliability and security using licensed spectrum. It also needs to be evolved to meet particular requirements brought on by massive IoT deployments.
Cellular network and device capability enhancements are being driven through the standardisation process at 3GPP to meet emerging requirements of ubiquitous coverage, long battery life and low-cost devices, enabled through software upgrades of existing networks. This is a key enabler in Orange’s strategy to become a major player in the Internet of Things.
Improved indoor coverage: The world-first EC-GSM (Extended Coverage) trial will be conducted in France using the 900 MHz band, with the aim to enhance device reachability by up to 20dB or a seven-fold improvement in the range of low-rate applications. This further extends the dominant global coverage of GSM in Europe and Africa to reach challenging locations such as deep indoor basements, where many smart meters are installed, or remote areas in which sensors are deployed for agriculture or infrastructure monitoring use cases. In addition, EC-GSM will reduce device complexity and thus lower costs, enabling large-scale IoT deployments. Another advantage of this technology is enablement by software upgrades of existing cellular networks, providing nationwide IoT coverage without additional hardware investments.
Reduced IoT device cost: In parallel, the world’s first LTE IoT trial in partnership with Sequans will take place using low-cost, low-complexity devices with one receive antenna (instead of two), and half-duplex FDD .This simplifies the device hardware architecture and reduces expensive duplex filters, allowing for 60 percent cost reduction in comparison with existing LTE Cat 4.
Extended battery life: In partnership with Sequans, Ericsson will also demonstrate energy efficiency over GSM and LTE networks with Power Saving Mode (PSM) technology. The PSM feature is applicable to both GSM andLTE, and supported by Evolved Packet Core (EPC). It enables extended battery life of communication modules such as sensors by up to 10 years thanks to optimised, power-efficient operations.
Alain Maloberti, SVP of Orange Labs Networks said: “IoT is a key area in Orange’s Essentials2020 strategic plan, and France should play a key role in IoT takeoff in Europe. In order to extend our connectivity offer, we are currently deploying a LoRa network. At the same time, we are preparing the future of cellular networks and we are happy to collaborate with Ericsson to be the first operator to demonstrate IoT over GSM and LTE in order to roll it out ahead of 5G availability in the market.”
Thomas Noren, vice president and head of Radio Product Management, Ericsson said: “IoT is an emerging market and presents great business potential for mobile operators. Ericsson is providing the software-upgrade-only solution to accelerate cellular network for IoT, allowing operators to leverage their infrastructure investments in order to quickly capture new business opportunities now and in the future with 5G. With our RAN and Core strengths, we are in the best position to support Orange’s innovation around IoT.”
Sequans Communications is the first chipset manufacturer to develop MTC LTE devices able to fit with connected form factors. Among possible solutions, there will be sensors, smart metering, assets tracking, and wearables.
Cellular networks optimised for IoT will be operational in 2017.
