Huawei has announced its “Unlicensed LTE (U-LTE)” solution at Mobile World Congress (MWC) 2014. U-LTE aggregates licensed and unlicensed spectrum bands to provide a better subscriber experience, strengthen overall network capacity, and expand market opportunities for mobile operators.
Â
U-LTE allows operators to aggregate data streams being carried on both licensed and unlicensed spectrum bands to strengthen network capacity, improve spectral efficiency, and dramatically improve user experience. Unlicensed bands allow for enhanced delivery of services with ultra-wideband frequencies, while at the same time licensed bands also for greater mobility and continuity of service of the enhanced service experience.
Â
Huawei’s U-LTE solution is based on existing LTE network technologies and does not require modifying existing security certification protocols or core network architecture for billing. Upgrading base stations to U-LTE is seamless without needing to stop operations.
Â
Typical deployment scenarios for U-LTE include indoor, outdoor and hotspot coverage locations. Small cell equipment can flexibly and cost-effectively employ U-LTE without adding additional sites and transmission resources.
Â
In a lab environment, Huawei has successfully achieved a 740 Mbps peak rate with a U-LTE product prototype aggregating multiple licensed and unlicensed spectrum data streams.
