The LAA-ready network was tested using a Huawei Lampsite base station in Vodafone Turkey’s Arena Store in Istanbul. It uses 40MHz of unlicensed spectrum in 5GHz and 15MHz licensed spectrum in 2.6GHz for three carrier aggregation.

In particular LAA technology is being used in trials designed to deliver Gigabit speed mobile services. In addition to this, there is growing ecosystem interest and momentum behind the CBRS-shared spectrum approach in the USA. There are dozens of companies reportedly planning CBRS deployments (including those for private enterprise networks).

Further enhanced LAA (feLLA) added the ability to operate a license-exempt autonomous uplink. Se hela listan på electronics-notes.com When configured with capability of initial partial subframe, the LAA SCell shall begin transmission of PDSCH/PDCCH/EPDCCH in the second slot of the subframe. Extending LTE to unlicensed spectrum globally – LAA (Qualcomm) summarizes the LAA as follows (These are not described explicitely in 3GPP, but it well describes on the motivation of LAA).

Again, this is designed for traffic offload and not coverage so control plane traffic is transported only over the licensed spectrum. The LAA Study Item is scheduled for completion in June 2015 ( 3GPP TR 36.889 ), paving the way for the specification work to be completed in the Release 13 timeframe (March 2016). The main goal of the Study Item is to identify the enhancements needed for LTE to operate in unlicensed spectrum and to ensure fair coexistence with Wi-Fi.
