The Federal Communications Commission (FCC) of the United States has created rules (47 CFR Part 96) that permit the use of the 3550-3700 MHz band under the Citizens Broadband Radio Service (CBRS). The technical standards for CBRS have been developed by Wireless Innovation Forum.
CBRS accommodates a variety of commercial uses, like LTE, on a shared basis with incumbent federal and non-federal users of the band. Access and operations are managed by a dynamic Spectrum Access System, and offered by Fairspectrum.
The Radio Spectrum Policy Group of the European Commission has defined Licensed Shared Access (LSA) as a regulatory approach to share spectrum between introduced licensee users, e.g. LTE or 5G, and one or more incumbent users.
The technical standards have been released by ETSI. Recently, ETSI has studied LSA for temporary access for local high-quality wireless network that serves the growing demand on private LTE and 5G networks. Fairspectrum has supplied more LSA systems than any other company in the world.
The Fairspectrum spectrum reservation tool automates the spectrum assignment process. On an intuitive user interface, the spectrum user defines the intended area, time, and frequency band of spectrum use. The tool calculates the interference impact to and from other spectrum users.
The reservation tool can be used to manage all spectrum assignments in a frequency band, like wireless camera communication in the 2.3 GHz band or wireless microphones on the TV UHF band. It is also excellent for managing incumbents or licensees as a part of an LSA system. The reservation tool makes it also possible to engage manually configured devices as a part of a modern dynamic spectrum access system.
TVWS systems operate in the terrestrial TV frequency band, 470-694 MHz. The most commonly referred TVWS regulations includ FCC (US), Ofcom (UK), and Dynamic Spectrum Alliance (DSA) globally with the emphasis in Latin America, Africa, and South-East Asia. IETF PAWS Protocol to Access White Space Database (PAWS) is applicable with all regulations.
Fairspectrum is the first company to open a commercial TVWS geolocation database service in Europe (in the UK).
