About MulteFire Release 1.1 Specification

The MulteFire Release 1.1 specification brings new optimizations for IoT, support for additional spectrum bands and general enhancements to Release 1.0. MulteFire 1.1 represents an evolution of MulteFire 1.0 technology with the aim to further improve its performance and enhance its potential.

The MulteFire 1.1 Specification is expected to be available for public download by mid-2019. To receive a notification when the specification becomes publicly available, please complete the following form:

Specification Capabilities

  • Enhanced existing MulteFire 1.0 broadband services in 5 GHz
    • Shortens access time—Grant-less Uplink (GUL)
    • Balance uplink and downlink coverage — Wideband Coverage Enhancements (WCE)
    • More robust mobility—Autonomous UE Mobility (AUM)
    • Self-Organizing Network (SON) features from LTE
  • Expanded IoT services with low power wide area support
    • eMTC (1.4 MHz to 5 MHz) in unlicensed bands (aka eMTC-U)
    • NB-IoT (200kHz) in unlicensed bands (aka NB-IoT-U)
    • Expands range of IoT services in addition to broadband in 5Ghz (10/20 MHz carrier bandwidth)
  • Added lower spectrum bands focusing on IoT
    • 4 GHz unlicensed, especially for eMTC
    • 9 GHz, aka sXGP in Japan or DECT spectrum globally, based on eMTC in 5MHz
    • Sub-1-GHz in the 800 and 900 range, especially for NB-IoT-U

About MulteFire Release 1.0 Specification

Release 1.0 specification, a key milestone in bringing MulteFire technology to market, is based on 3GPP Releases 13 and 14, and defines LTE to operate in unlicensed and shared spectrum while ensuring fair sharing of spectrum with other users and technologies. By removing the requirement for an anchor in licensed spectrum, MulteFire enables new use cases and new deployments to take advantage of the benefits of LTE technology. Version 1.0.1 of the specification is available for public download. Please complete the form here to access the 1.0.1 specification.

Specification Capabilities

  • Builds on elements of 3GPP Release 13 License Assisted Access (LAA) for the downlink and Release 14 enhanced LAA (eLAA) for the uplink
  • Includes enhancements for operation solely in unlicensed spectrum such as robust procedures for mobility, paging, initial access and efficient uplink control channels
  • Implements Listen-Before-Talk for fair coexistence with technologies using the same spectrum such as Wi-Fi and LAA, as well as co-existence between different MulteFire networks
  • Defines a Neutral Host access mode where the same deployment can serve multiple operators, as well as a traditional access mode for a single network operator
  • Enables access authentication with or without a SIM card to provide services for subscribers from different types of service providers, including mobile operators
  • Supports a range of LTE services, including Voice over LTE (VoLTE) and high speed mobile broadband

Specification maintenance is ongoing and some revisions may have been made since December 2016. Early access to specification work is available to MulteFire Alliance members; membership information is available at www.multefire.org/join/.
