The first end-to-end live trial of CBRS with carrier aggregation using 3.5 GHz LTE equipment

Abstract

This demonstration presents the first end-to-end field trial of the US three-tier Citizens Broadband Radio Service (CBRS) with carrier aggregation using commercial 3.5 GHz network elements (UEs, eNBs, EPC) and platforms (NMS, SON). The live trial shows how shared spectrum is assigned to an operational LTE base station and how it boosts the end user mobile data rate due to extended bandwidth availability. Also, the performance of the CBRS is evaluated and compared to the FCC requirements for the evacuation time.

Reseña del servicio de radio de banda ancha ciudadana

“…2. Los usuarios de CBRS son: PU también conocidos como Titulares en el nivel 1, SU con Licencia de Acceso Prioritario (PAL) en el nivel 2 y SU de Acceso General Autorizado (GAA) en el nivel 3 Al hablar de PU, se refiere a Titulares de tres tipos de servicios, en primer lugar, de 3550 MHz a 3650 MHz se encuentran los sistemas de radar de la Marina de EEUU; en segundo lugar de 3600 MHz a 3650 MHz las estaciones receptoras terrenas de Servicios Fijos por Satélite (FSS, Fixed Satellite Service); y finalmente, de 3650 MHz a 3700 MHz los servicios de banda ancha inalámbricos, que corresponden a los Proveedores de Servicios de Internet Inalámbricos (WISP, Wireless Internet Service Providers) y que a futuro pasarán a ser usuarios PAL o GAA [4], [12].…”

Designing a Testbed Infrastructure for Experimental Validation and Trialing of 5G Vertical Applications

“…TUAS also co-operated with CORE+ project through WISE2 project and was a full project consortium partner in the follow-up project CORE++ [42]. These projects studied the LSA [43,44,45,46,47,48,49,50,51] and SAS [52,53,54] concepts by developing the framework, participating in the regulatory work and field trialing the developed systems. TUAS participated in the development of repositories for both LSA and SAS and in developing the spectrum sensing system fulfilling the requirements of Environmental Sensing Capability (ESC) in SAS.…”

Deep Learning applied for Spectrum Sensing using multiple and concurrent stages

“…in [2] the author present a good example of dynamic spectrum access in TV white space. The Citizens Broadband Radio Service (CBRS) [3], [4] are a good example of opportunistic spectrum sharing in where we use a frequency band that had been reserved for radar systems. to maximise the use of the spectrum new ways of spectrum sensing are invented.…”
