MulteFire: LTE on Licence Exempt Spectrum
Oct 18 2016
Originally created by Qualcomm and now operating behind the MuLTEfire Alliance, MulteFire is a new, LTE-based technology that solely operates in unlicensed spectrum. It opens up new opportunities by operating 4G LTE technology solely in unlicensed spectrum such as the global 5 GHz. This differs from Licensed Assisted Access (LAA) and LTE - Wi-Fi link aggregation (LWA), both of which aggregate unlicensed spectrum with an anchor in licensed spectrum.
A key principle in the design of MulteFire is fair coexistence with Wi-Fi. It is based on LAA and uses similar coexistence technologies, including “Listen Before Talk,” which is required for global deployments. This also means that MulteFire, like LAA, is a good neighbor in unlicensed spectrum with any other technology, including Wi-Fi, LAA and LTE-U.
+ MulteFire Alliance was formed in December 2015
+ It builds on elements of the 3GPP Release 13/14 standards for Licensed Assisted Access (LAA/eLAA)
+ MulteFire is based on LTE, it will operate in 20MHz TDD sub-bands, capable of peak data rates up to 400Mbps
