The Internet of Things (IoT) will connect billions of devices worldwide but will require innovative approaches to wireless connectivity to meet the demands for capacity, coverage, and reliability. The Industrial IoT (IIoT) segment of IoT is operationally intensive and can be defined as a “business-critical” market.
MulteFire®, a cellular-based technology, meets the strict demands of the business-critical markets. Since its inception, the MulteFire Alliance has been devoted to supporting the common interests of members, users, and developers in the application of LTE and next-generation (5G) mobile cellular technology that use only shared or unlicensed radio spectrum.
The Alliance will host a MulteFire Open Day in San Jose, California on December 4th, to deliver an update on technology development and deployment traction. The free event is open to anyone with an interest in MulteFire.
Based on 3GPP specifications, MulteFire delivers LTE-like performance with Wi-Fi-like deployment ease. It allows anyone to set-up and to manage their own, private or neutral host network, as they could with Wi-Fi, while also benefiting from high-quality LTE services and functionality supporting data IP and voice services locally. The Release 1.0 specification, publicly available to download on the MulteFire website, defines an end-to-end architecture design and radio air interface to deliver key performance advantages. It implements Listen-Before-Talk (LBT) for fair co-existence with other technologies operating in the same band.
The Alliance is working on the Release 1.1 specs that will add further optimizations for IoT, notably support for NB-IoT and eMTC. MulteFire NB-IoT support is aimed at low power, wide area (LPWA) IoT-use cases with 200 kHz carrier bandwidth. MulteFire eMTC will support the broadest range of IoT use cases, such as IIoT, with 1.4 MHz carrier bandwidth (BW).
Additionally, Release 1.1 adds new spectrum, including regional bands 800/900 MHz and 1.9 GHz and the global 2.4 GHz unlicensed band.
