LTE in the Unlicensed Spectrum Webcast

1   Hour | Webcast - recorded | Where & When


The constant growing demand for higher data rates in mobile devices is causing network Operators to think on innovative paths to help cope with the mobile capacity crunch and, the active use of unlicensed spectrum has become a key enabler.

With more than half of the wireless internet traffic, WLAN is undoubtedly the leading technology for delivering ubiquitous wireless connectivity. Historically WLAN and cellular have been viewed as competing technologies with separate standards bodies and solutions; however, thinking is being challenged with recognition that, with inter-working, the two technologies can be use used to complement each other and improve the overall performance of the network.

On the other hand, WLAN is also one of multiple technologies that make use of the ISM band. The lack of any licensing requirement makes this part of the spectrum very attractive to Operators and therefore it’s been a major driver in the standardization bodies lately which are working towards ensuring LTE can be deployed in the unlicensed spectrum.

This is happening in multiple ways…

• LTE and WLAN inter-working defines a framework to enable a seamless and smart traffic offload between the two technologies. In the 3GPP Release 13, RAN-controlled LTE-WLAN Interworking (RCLWI) takes RAN assisted WLAN Offload (Release 12) to a new level by increasing the offload control by the 3GPP network.

• LTE-WLAN link aggregation (i.e. Release 13 LWA and LWIP) goes beyond the offload and allows the simultaneous combination of both technologies to opportunistically boost data rates.

• LTE in the unlicensed spectrum (i.e. LTE-U, LAA) takes advantage of the LTE-A feature, carrier aggregation, to enable the use of LTE in the underutilized 5GHz ISM band. To ensure co-existence with other technologies, new mechanisms like LBT (Listen-Before-Talk) or carrier sensing have been defined by the 3GPP.

This webcast describes the technical fundamentals, motivation and test challenges behind the new standardization work in the area of collaboration (i.e inter-working between LTE and WLAN) and also competition (LAA, LTE-U) in the unlicensed bands.


Project managers, developers, and engineers designing chipsets, developing modems, or buildling wireless devices. Anyone interested in learning the technical fundamentals and test challenges behind the new standardization work around LTE in the unlicensed spectrum.
