Wireless Innovation Forum Releases Essential Specifications for US Shared Spectrum 3.5 GHz

first_img Architecture of SAS-CBSD Interfaces Description of SAS-CBSD Message Exchanges CBSD States and State Transitions SAS-CBSD Procedures Message Encoding and Transport Parameters of SAS-CBSD Messages Wireless Innovation Forum’s Spectrum Sharing Committee was specifically formed to develop the solutions and standards that will encourage rapid development of the CBRS ecosystem, protect incumbent operations, and benefit all potential stakeholders in the band. The SSC benefits from participation of a broad-based group that includes wireless carriers, network equipment manufacturers, potential SAS Administrators, satellite operators, existing 3650-3700 MHz band licensees, and other parties with an interest in the 3550 MHz band. The committee has formed multiple sub-groups/task groups, including a Joint WG1/WG3 architecture group and an FSS Incumbent Protection Subgroup under WG1. Participation in the committee’s multiple sub-groups/task groups currently encompasses some 277 participants from over 60 different organizations. Work products from the committee can be found here: http://www.wirelessinnovation.org/work-products-and-public-files.The Wireless Innovation Forum welcomes all interested organizations to participate in our committees.To learn more about membership options or to apply for membership in the group please visit: http://www.wirelessinnovation.org/join. The SAS-CBSD Protocol document also includes references, definitions and history as well as: SAS-SAS Prerequisites SAS-SAS Procedures SAS-SAS Synchronization Message Encoding and Transport Parameters of SAS-SAS Messages Foundational documents published in the past year include: “Interim SAS to CBSD Protocol Technical Report B”; “Interim SAS to SAS Protocol Technical Report B”; “Interim SAS to SAS Protocol Technical Report-A”; and “Interim SAS to CBSD Protocol Technical Report-A”. The newly approved specifications as well as all foundational documents are available here.Announced in February 2015, the SSC supports five working groups, each collaborating working on separate aspects of a common goal: to ensure that the 3.5 GHz band can be successfully commercialized. The SSC working groups are: Operational and Functional Requirements (Interoperability Focus) Security Requirements Protocol Specifications Testing and Certification Operations The Wireless Innovation Forum announced today member approval and public availability of its Spectrum Sharing Committee’s (SSC) highly anticipated signaling protocols and procedures to be used in the U.S. 3.5 GHz Citizens Broadband Radio Service (CBRS) band for the Spectrum Access System (SAS) – Citizens Radio Broadband Service Device (CBSD) and “Spectrum Access System (SAS) – SAS” Interfaces.These standards are the first of their kind addressing the new FCC Part 96 rules for CBRS. Publication of these standards represents a major milestone for enabling U.S. commercialization of the band. Access to spectrum under the Part 96 rules is managed in the CBRS band through the use of a Spectrum Access System (SAS), which protects incumbents from interference from lower tier priority access license (PAL) and general authorized access (GAA) users, and protects PAL users from interference from other PAL users and GAA users.This achievement by the Wireless Innovation Forum’s Spectrum Sharing Committee is the result of an extensive collaboration among diverse stakeholders working diligently for the past two years. These new standards and solutions will enable the rapid development of a robust CBRS ecosystem, protect incumbent operations, and benefit all potential stakeholders in the band. These documents will also lay the foundation for all deployments in the CBRS band and possibly other shared bands in the future.In addition to providing definitions, references, and history, elements included in the SAS-SAS Protocol include:last_img read more

Bila di Udara ada Air Navigation Charges, maka di Laut ada Traffic Separation Scheme

first_imgSumber: Istimewa Bila dalam dunia dirgantara dikenal istilah Air Navigation Charges, yaitu skemayang mengatur tentang arus perjalanan suatu penerbangan di ruang udara negara lain. Persisnya setiap pesawat harus tunduk terhadap arahan dari masing-masing ATC (Air Traffic Control) yang ada di setiap negara ketika melintasinya. Ada juga biaya “service” yang dikenakan kepada setiap penerbangan yang melintasi ruang udara suatu negara. Tapi, bukan hanya pesawat saja yang harus tunduk pada arahan dari ATC, pun halnya dengan kapal laut yang juga harus tunduk pada TSS selama melakukan navigasi pelayaran.Baca Juga: “Air Navigation Charges,” Biaya Jasa Navigasi ATC Saat Pesawat Melintas di Suatu NegaraNah, mungkin sebagian dari Anda akan bertanya-tanya, “Apa sih TSS itu? Apakah penting bagi kelautan Indonesia?” Merujuk pada definisinya, TSS atau Traffic Separation Scheme merupakan sistem rute manajemen lalu lintas maritim yang pengaturannya berada di bawah International Maritime Organization (IMO). Jalur lalu lintas maritim ini menunjukkan arah umum kapal di zona terkait dan semua kapa yang berada di bawah navigasi dari TSS semuanya berlayar ke arah yang sama (beraturan).Adapun penerapan dari TSS ini akan berdampak pada:1. Membantu mengurangi dan mengelola lalu lintas di arus lalu lintas yang berlawanan,2. Membantu pengelolaan kapal yang hendak masuk atau keluar dari area pelabuhan,3. Arahan tentang jarak aman antar kapal,4. Menyediakan rute untuk deep draught vessels, dan lain sebagainya.Selain mengatur tentang arus lalu lintas kapal, TSS ini juga turut memberikan pedoman terkait kapal yang hendak melintas memotong jalur yang sudah ada. Menurut aturan TSS yang ada di laman wikipedia, setidaknya kapal yang hendak melintas ini membuat sudut 90 derajat layanya zebra cross yang ada di jalanan.Hadirnya skema lalu lintas maritim semacam ini lantaran adanya peningkatan dari jumlah modanya itu sendiri. Jikalau tidak diatur dengan sedemikian rupa, maka tak pelak kekacauan di jalur laut akan siap mengancam. Poin dari hadirnya TSS adalah menjamin keamanan dan keselamatan dalam lalu lintas pelayaran.Baca Juga: Tahun 2020, Roller Coaster Hadir di Kapal Pesiar Untuk Jelajahi LautSaat ini TSS telah hadir di Selat Sunda dan Selat Malaka, mirip dengan Air Navigation Chargers, setiap kapal yang melewat zona TSS juga berkewajiban membayar biaya jasa pelayanan panduan pelayaran, sesuai peraturan, besarnya biaya jasa TSS ditetapkan dari bobot tonase kapal.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Like this:Like Loading… Related”Air Navigation Charges,” Biaya Jasa Navigasi ATC Saat Pesawat Melintas di Suatu Negara17/10/2019In “Bandara”Mengenal Bandara Tanpa ATC, Bisa Sembarang Mendarat dan Lepas Landas?09/09/2020In “Bandara”Penasaran dengan Bagian dalam Menara ATC?

Stephanie Barnett Chosen Southland Women’s Tennis Player of the Week

first_imgFRISCO, Texas – Nicholls sophomore Stephanie Barnett has been selected Southland Conference Women’s Tennis Player of the Week, the league office announced Tuesday.
