This paper discusses the real-time feature and efficiency of dynamic spectrum allocation and presents a new spectrum allocation algorithm based on the master-slave parallel immune optimization model. The agency grants companies licenses to use the spectrum. In the mobile phone market, the FCC has auctioned off spectrum, generating billions of dollars in revenue for the government. The FCC also decides which frequencies of spectrum can be used for which purposes. For mobile phones, it has allocated spectrum generally between 700 MHz and 2.6 GHz. In wireless communication system, the radio spectrum is one of the biggest resource constraints with limited availability in nature. WIRELESS BROADBAND SPECTRUM POLICY 1. 54 : Iss. Wireless Spectrum: The wireless spectrum consists of electromagnetic radiation and frequency bands. Radio Spectrum Allocation. The radio spectrum is the radio frequency (RF) portion of the electromagnetic spectrum. In the United States, regulatory responsibility for the radio spectrum is divided between the Federal Communications Commission ( FCC) and the National Telecommunications and Information Administration ( NTIA ). A plurality of dynamic spectrum allocation (DSA) channels (222, 224) can be identified. P. Ingole. The Federal Communications Commission (FCC) also regulates the physical layer technologies to be employed. The article proposes to use machine learning (ML) paradigms to address challenges in the fifth generation (5G) wireless networks. 12, DECEMBER 2008 5517 Joint Rate and Power Allocation for Cognitive Radios in Dynamic Spectrum Access Environment Dong In Kim, Long Bao Le, and Ekram Hossain AbstractWe investigate the dynamic spectrum sharing prob- lem among primary and secondary users in a cognitive radio The National Communications Authority (NCA) has published the National Frequency Allocation Table (NFAT) for wireless communications services in Ghana. contained in the Kenya Information and Communications Act (KICA), Cap 411A (as amended) public benefit will be maximised where radio frequency spectrum resources are allocated to the highest value use or uses to consumers and the broader public good or social benefit.

Today, the South Korean government has announced that it will be making 5G spectrum directly available to non-telcos for the first time. 7, no. IMDA manages the frequency allocation and assignment for commercial and government spectrum usage. The radio frequency spectrum is divided into bands, allocated for different type of services. For spectrum bands, recommended by the International Telecommunications Union (ITU), specific channeling plans may be adopted for assignment. Introduction The wireless spectrum is the cornerstone of wireless communication. Many existing works assume that the spectrum resource is single-unit and indivisible, which greatly limits users capability to utilize the spectrum. The railways aims to improve public safety Spectrums are decided based on allocation policy namely Random Switch and Round Robin Switch. In this paper, we adopt a suitable mathematical formulation for opportunistic channel allocation. By Vibha Varshney, Dinsa Sachan, PADMAPARNA GHOSH. Abstract.

In recent decades, cognitive radio-based networks have garnered increased attention and have been well studied to overcome the problem of spectrum scarcity in future wireless communications systems. Wireless Spectrum Allocation: What are the Implications for Industry Players, Policy Makers, and the Consumer? CRs determine the spectrum portions unoccupied by the licensed users known as spectrum holes or white spaces, and In this article a cognitive spectrum allocation procedure is proposed. Although interference can be avoided by assigning different wireless services to different licensed frequency bands, such a xed spectrum allocation strategy may result in spectrum under utilization. The ITU-R endeavours to guarantee efficient, equitable, rational and economical radiofrequency usage by all wireless communication services. Military Communication Institute POLAND ABSTRACT The dynamic spectrum management for military wireless networks is discussed in this paper.

IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS, VOL. In this paper we present a novel approach for allocation of transmit power, which is based on a non-greedy procedure that aims at maximizing transmission rate while also controlling interference levels. Now, Washington is back in the business of putting vast chunks of An efficient method of spectrum allocation is a key factor to improve quality of service and performance of The Infocomm Resource & Technology Division of IMDA undertakes Radio spectrum, as the physical support for wireless communication, both for fixed applications and especially for mobile broadband, is becoming an extremely strategic, valued, and demanded resource. The Command and Control management approach is the one currently employed by most regulators around the globe. Spectrum Allocations Frequency management is done in several steps Frequency allocation: A band of radio frequencies identified by an upper and lower frequency limit earmarked for use by one or more of the 38 terrestrial and space radio communication services defined by the International Telecommunication Union under specified conditions. FDD, and LTE bands between 33 & 41 are for unpaired spectrum, i.e. IMDA is responsible for the management, allocation and assignment of the RF spectrum. While the problems in some of the wireless networking applications are amenable to general resource allocation methods, others require a more specialized approach suited to their unique structural characteristics. Without degrading performance of existing users. In the past decade, the FCC (Federal Communications Commis-sion) and its counterparts across the world have been using In a wireless communication system, relaying techniques can offer significant benefits in the throughput enhancement and range extension.
