INTRODUCTION 1. In this Order we grant a request by the State of Alaska (Alaska) for a waiver of Section 90.20(c)(3) of the Commission’s rules to operate a new VHF base station on four channels using non- standard channel centers. 1 II. BACKGROUND 2. Alaska operates a wide area VHF public safety trunked radio system known as the Alaska Land Mobile Radio System (ALMR) which serves local, state and federal agencies throughout the State of Alaska using a single shared infrastructure.2 Users of the ALMR system share repeaters, RF sites, towers, and dispatch centers.3 3. The ALMR system operates using Project 25 technology and pairs approximately 1.5 megahertz of spectrum from the Public Safety Pool (150 MHz band) with an equal amount of spectrum from the Federal Government (138-144 MHz band) to create 110 channel pairs (12.5 kHz bandwidth).4 Channels from the Public Safety Pool are used in the ALMR system for base station transmissions and channels from the Federal Government band are used for mobile station transmissions.5 4. When it originally designed its ALMR system, Alaska noted that it had some difficulty pairing Public Safety Pool spectrum with spectrum from the Federal Government because channels in the Public Safety Pool from the 150 MHz band are assigned using channel centers spaced every 7.5 kHz whereas the channels from the Federal Government from the 138-144 MHz band are assigned using 1 See ULS application number 0007652388, filed February 7, 2017 (Alaska Application). -
Private Land Mobile Radio Services: Background
Federal Communications Commission Wireless Telecommunications Bureau Staff Paper Private Land Mobile Radio Services: Background December 18, 1996 Michele Farquhar, Chief, Wireless Telecommunications Bureau Project Team David Wye John Borkowski Eli Johnson Sean Fleming Federal Communications Commission Wireless Telecommunications Bureau Staff Paper Private Land Mobile Radio Services: Background December 18, 1996 Michele Farquhar, Chief, Wireless Telecommunications Bureau Project Team David Wye John Borkowski Eli Johnson Sean Fleming Federal Communications Commission Wireless Telecommunications Bureau Staff Paper The authors wish to gratefully acknowledge the assistance of the many representatives of the private wireless community who contributed to this Staff Paper. Within the Federal Communications Commission, Wireless Telecommunications Bureau, many people were also generous with their time and attention, and contributed valuable insights and comments. The information, perspectives, and suggestions all these contributors provided greatly improved the final product. The views expressed in this Staff Paper do not necessarily represent the views of the Federal Communications Commission or any individual Commissioner. This Staff Paper is not a statement of policy by the Commision, nor does it bind the Commission in any way. We do not intend by this Paper to prejudge the outcome of any proceeding that is now or may in the future come before the Commission. Executive Summary Since the 1920s, the private land mobile radio services (PLMRS) have been meeting the internal communication needs of private companies, state and local governments, and other organizations. These services provide voice and data communications that allow entities to control their business operations and production processes, protect worker and public safety, and respond quickly in times of natural disaster or other emergencies. -

Land nationwide system built on open standards with consistent Mobile Radio System (LMRS) is a legacy narrowband technology used for critical voice communications with limited use for data architecture, and fund raising approach for the transition to a applications. Recently Long Term Evolution (LTE) emerged as new nationwide system. As explained in [6], communication of a broadband communication technology that has a potential time critical information is an important factor for emergency to transform the capabilities of public safety technologies by response. In [7] and [8], insights on cognitive radio technology providing broadband, ubiquitous, and mission-critical voice and are presented, which plays a significant role in making the best data support. For example, in the United States, FirstNet is building a nationwide coast-to-coast public safety network based use of scarce spectrum in public safety scenarios. Integration of LTE broadband technology. This paper presents a comparative of other wireless technologies into PSC is studied in [9], with survey of legacy and the LTE-based public safety networks, and a goal to provide faster and reliable communication capability discusses the LMRS-LTE convergence as well as mission-critical in a challenging environment where infrastructure is impacted push-to-talk over LTE. -
