Licensed Assisted Access

Licensed Assisted Access is an LTE feature that leverages the 5 GHz unlicensed band in combination with licensed spectrum to deliver a performance boost for mobile device users.

By adding a new radio access option and employing the fair sharing principles listen before talk (LBT), LAA optimizes available wireless network resources, and improves app coverage for all users whether their devices are using LAA, licensed cellular or Wi-Fi. LAA is a key milestone on the road to 5G, leveraging a combination of licensed and unlicensed spectrum, and using higher frequency bands on a small cell architecture.

LAA improves app coverage

To improve app coverage indoors in any size or type of commercial building – whether that’s a suburban shopping center, train station or a high-rise office building – Ericsson is adding Licensed Assisted Access (LAA) to its indoor small cell portfolio, RBS 6402 Indoor Pico cell. LAA introduces the security and performance associated with high-performance LTE networks to spectrum available in the 5 GHz band. Too meet the outdoor hot spots challenges Ericsson LAA is added to the outdoor small cell Micro Radio 2205.

LAA benefits all consumers and business users on smartphones and other mobile devices:

  • Users on LAA: Consumers can leverage the combination of licensed and unlicensed bands to achieve higher peak rates indoor and outdoor.
  • Users on cellular licensed bands only: By distributing traffic between the licensed and unlicensed bands, LAA frees up capacity on the licensed spectrum, benefiting users on those bands.
  • Users on Wi-Fi only: LAA frees up capacity for Wi-Fi users, by employing fair sharing techniques and using the 5GHz band more efficiently.

Combining licensed and unlicensed technologies and leveraging higher frequency spectrum bands on small cell architectures, LAA is a key milestone on the road to 5G. LAA delivers an indoor and outdoor performance boost for smartphone users, while optimizing available wireless network resources for all users.
