The main idea of LAA is to deploy LTE in the unlicensed band (mainly the 5GHz band), which is abundant with available spectrum. However, the major concern

Here in the Ericsson Research blog, we have previously described how licensed assisted access (LAA) enables mobile device users to be served by a combination of licensed and unlicensed spectrum bands at the same time. Watch live and On Demand shows, and manage your DVR, whether you're home or on the go. Licensed-assisted access (LAA), which conveys data information via both licensed and unlicensed bands through spectrum aggregation, becomes a promising solution to enhance the capacity of wireless systems. In view of the potential impact on the incumbent system operating in unlicensed bands, the medium access control (MAC) protocol design for LAA system to harmonically coexist with its LAA R14 targets enhancements to support aggregation for both uplink and downlink MuLTEfire Broadening LTE technology and ecosystem to new deployment opportunities Licensed Spectrum Exclusive use Unlicensed Spectrum Shared use LAA (Licensed-Assisted Access) Targeting mobile operator deployments in Europe, Japan, and beyond2 based on 3GPP Rel. 13 and beyond LTE Carrier Aggregation with licensed LAA R13 uses the licensed spectrum for the uplink, with planned support for uplink in unlicensed spectrum in 3GPP R14. Since MulteFire only relies on unlicensed or shared spectrum, MulteFire will support R13 components for the downlink and align with the definition of R14 LAA components for the uplink in unlicensed or shared spectrum.

The underlying protocol is similar to LAA in that it also conforms to the LBT protocol. The biggest beneficiaries of MulteFire are the Internet Service Providers and cable companies. MulteFire now allows for easier WiFi-like deployment models without relying on licensed spectrum as the anchoring service.

LAA (Licensed Assisted Access) was introduced in 3GPP release 13 as part of LTE Advanced Pro and is a method used to designate public spectrum in the speedy and currently spacious 5GHz band and has been designed to assist standard call services.

wTo emerging complementary spectrum authorizations have attracted industry and academia, Licensed Shared Access (LSA) and License Assisted Access (LAA). This video demonstration, also shown at Mobile World Congress 2016, shows downlink and uplink LTE operation in unlicensed spectrum and compares coverage betw In spectrum sharing systems, such as long-term evolution license assisted access (LTE-LAA) [1]–[5] and the IEEE 802.11 wireless local area network (WLAN) systems [6], [7], reliable spectrum sensing of channel busy/idle states is needed to properly implement carrier sense multiple access with collision avoidance (CSMA/CA) schemes. In CSMA/CA, the Swedish network giant Ericsson continued its small cell crusade with the announcement of license assisted access (LAA) to its small cell portfolio. This LTE technology allows users to tap into unlicensed spectrum, typically used by wifi, to augment their cellular performance.
