As one of the latest LTE technologies, License Assisted Access (LAA) leverages both licensed spectrum and unlicensed spectrum to carry data traffic of mobile service. The core part of LAA technology has been finished in December 2015. Two months later, Baicells launch the world's first LAA small cell together by using Intel TranscedeTM SoC processing chip. Baicells and Intel showcase the business capacity of the LAA small cell in the coming MWC held in Barcelona Spain during February 22rd to 25th, 2016. Based on 3GPP Release 13, the LAA small cell utilizes Listen-Before-Talk (LBT) to ensure coexistence of LAA and Wi-Fi on unlicensed spectrum.
The concept of LAA was first generated in a 3GPP wireless access network standard conference in December 2013. LAA is born to reduce operators' ever-increasing network capacity pressure, to discover more available spectrum resource, to improve the data transmission rate of mobile network and enhance network experience. Better network performance can also be provided by LAA.
"By aggregating licensed and unlicensed spectrums, Baicells LAA small cell can double the data rate. For instance, by aggregating 20MHz licensed spectrum with 20MHz unlicensed spectrum, the peak download rate can reach 300Mbps, thus expanding the capacity of RF broadband. LBT can eliminate the effect on the existing Wi-Fi and make LAA coexist with Wi-Fi." Mr. Bai Wei, VP of Baicells, told the reporter. "Baicells LAA small cell adopts Intel TranscedeTM SoC processing chip. Excellent processing ability of the chip can optimize the performance of the small cell. Combined with Baicells' own technical advantages, we decide to launch the word's first LAA small cell with Intel, aiming to help the operator provide improved network capacity and enhanced user experience at a lower cost".
