(Telecompaper) Qualcomm said it's extending its LTE product to include unlicensed spectrum (LTE-U). The technology has already been integrated into its latest small cell products and RF transceivers for mobile devices. Qualcomm also announced that it successfully completed over-the-air testing to prove co-existence between multiple LTE-U and Wi-Fi access points in the unlicensed spectrum under extreme load conditions. Qualcomm will show the new products with a number of LTE-U demonstrations at Mobile World Congress. LTE-U is designed to augment nework capacity by using channels in the less-crowded 5 GHz unlicensed bands, normally used for Wi-Fi. LTE-U uses several coexistence features to support fair share use among the multiple users and technologies that access those bands.
Qualcomm's products using the technology include the FSM99xx, a family of small cell SoCs available in the second half of 2015, the FTR8950 RF transceiver for small cells and the WTR3950, a 28 nm RF transceiver for mobile devices, which will be commercially sampling in the second half of 2015.
