LTE-WLAN aggregation (LWA)

LTE-WLAN Aggregation (LWA) is a technology that allows mobile devices to support both Long Term Evolution (LTE) and WiFi. Both techniques can be used simultaneously. The actual configuration is determined by the network. The background to this technique is the low-cost LTE communication over the license-free frequency bands used by WLANs. Similar concepts are pursued by LTE Unlicensed (LTE-U) and Licensed Assisted Access

(LAA).The LWA concept requires minimal changes to the WLANs and the LTE infrastructure and allows WLANs to be seamlessly integrated into the network as a Radio Access Network

(RAN). LTE-WLAN Aggregation is a project of3GPP Release-13 that enables mobile devices to use the LTE infrastructure and WiFi simultaneously. By communicating over WLANs and LTE simultaneously, a higher and more efficient data flow is achieved. LWA can split a single carrier signal according to channel utilization, allowing streaming and downloads to be performed with increased performance. The subscriber device automatically uses the deployed WLAN without user intervention.
