PROJECT DESCRIPTION

Project information

As the technologies for LTE in unlicensed bands approach readiness for operational deployment, the use cases and real-world deployment considerations will become more clear and targeted by vendors
and operators. 

This, in turn, will provide more clarity about how the technology
will impact the wireless market, and impact incumbent technologies (especially Wi-Fi) in nearby deployments.

The recommendation is to update the sections in previous WBA work outlining the anticipated deployment of unlicensed LTE on its
LTE – Wi-Fi RAN interworking variations (.e.g LWA, LWIP, MulteFire), and discussing these impacts, in situations such as:

  • LTE/Wi-Fi RAN Interworking and Carrier Wi-Fi coverage
    overlapping scenarios

– Indoor/Outdoor deployment

– Macro and Small Cell usage and interaction

– Integrated (into licensed nodes) or standalone unlicensed nodes

  • Neutral host support

Outcomes / Target Audience

Current Unlicensed LTE work streams are evolving in the
following order:

  1. Market Drivers
  2. Deployment Guidelines
  3. Trial (LWA, LWIP, MulteFire)

Keywords

Unlicensed Spectrum, LTE-U, LAA, LWA, LWIP, Standalone access, Policy, Use Cases, End-to-end trial

Business objectives

  • Validate business opportunity of uLTE technologies
  • Capitalize on Wi-Fi investments to augment range of services provide to LTE providers as offload
