US President’s Council of Advisors on Science and Technology Report Proposed Major Changes to Spectrum Policy, Using Federal Spectrum
1. Define a spectrum license to be a right not to be interfered with, but with no right to exclude --- all spectrum therefore usable by somebody
2. Provide a band where all types of users have the same capability, but still allow for purchasing protection (3 tiers)
3. Allow for spatial and temporal sharing of a band among a wide class of users (initially, federal radars and civil broadband)
4. Automate de-confliction through micro transactions based on interference criteria
5. Shorter term licenses to enable successor uses to enter the band naturally

FutureWorksLSA system regulatory setup processLSA system regulatory setup processLSA system regulatory setup processLSA system regulatory setup processSharing framework, sharing arrangement and LSA license
1. Sharing Framework
The Regulator sets up the Sharing Framework involving Incumbents and potential LSA Licensees to define:
• LSA spectrum resources, incumbent protection requirements on a global/ national level
• QoS in terms of availability level of the LSA spectrum resources to the potential LSA Licensee
• validity of the Sharing Framework (lifetime)
2. Sharing Agreement
The Incumbent and the LSA Licensee define details of the sharing operation
• precise definition of LSA spectrum resources on regional level incl. exclusion/restriction/protection zones and changes over time
• parameters related to spectrum resource availability (e.g. lead time based on system latency spec, evacuation case)
• parameters related to transmitter operation at LSA Licensee (e.g. EIRP / Transmit power limits)
• parameters related to receiver operation at Incumbent and LSA Licensee (protection criteria).
3. LSA License
The Regulator grants a LSA License to a particular LSA Licensee.
• LSA Licensee obtains all relevant information from the Sharing Framework relevant for operating its spectrum resources.
• System Administration configures the system identity and the security authorization profiles for this LSA Licensee.

• LSA allows for sharing while meeting the requirements of mobile operators and incumbents for predictable conditions of spectrum use and hence predictable QoS.
• LSA opens bands otherwise locked for long time for harmonized MBB use like the 2.3 GHz band in Europe supported in commercial devices today.
• LSA is a simple concept which can be implemented today with evolution path towards dynamic use cases like spectrum pooling and the US SAS concept.
• The Finland trial has proven above aspects testified by all stakeholders including regulator, incumbent, mobile operator and supplying industry. Visit http://core.willab.fi/ for more information on the trials
• Let’s work together to make the ecosystem exist and grow!
