ABSTRACT In this global world of technologies where the communication is being modern day by day, on every other day the new technologies are being invented so in this vast world of growing technologies the cognitive radio network is another addition and a step toward fast and secure communication. Cognitive radio network is the network used for wireless communication which uses the spectrum of frequencies. It is an intelligent network in a sense that it can recognize the channels in use or vacant
Every day the wireless communication is getting more advanced comparing to what is was yesterday. Every generation of mobile communication get advanced with a higher speed, frequency band, better connectivity, security and high data rates in transmission. For all these reasons, it’s clear how the 4G is success more than the 3G networks, and the same thing will happen to the 4G after lunching the 5G in the near future. In this paper, I will try to describe the 4G networks and 5G networks in contest
Future mobile applications demand novel wireless communication technologies due to new challenges as- sociated with the shortage of spectrums, low-power radio architectures, and communication security. For example, though mmWave can fulfill some of the spectrum demands, it can still struggle to meet the growing demands for higher data connectivity over a myriad of devices, e.g., Internet of Things (IoT) []. Therefore, more bands in the electromagnetic domains will be needed. Besides, in current and
presents implementing wireless network in computer communication In that the following devices includes WI-FI, Bluetooth, WiMAX, mobilesNetworks and latest LI-FI technology. This paper clears the idea of using this wireless network. A review of what is needed to build a generic wireless network is provided. We can alreadyknow about the wireless network and we can connect the computer by using this wireless network. The paper also advances some of the major security risks that wireless networks face.

Wireless communication is the transfer of data between two or more points that are not connected by an electrical conductor. In addition, wireless communications networks are less expensive to install and preserve than equivalent wired systems. Wireless communication has become possible due to the discovery of radio waves. With the first breakthrough of the radio signal within the 19th century, along with founders Nikola Tesla and Guglielmo Marconi, evolution of the wireless technology has improved
In this research paper we review three promising short-range wireless communication such as Radio FrequencyIdentification (RFID), Bluetooth, zigbee and Near-field Communication (NFC).NFC mobile services are an important emerging areafor NFC technology, with great potential for growth. The NFC Forum’s strategy for accelerating the growth of this business areaincludes recognizing and describing what is needed to realize successful NFC mobile services, such as key technologies, typical usecases, and
With the rapid development of wireless communication systems, there will be a need for the network deployment of independent mobile users [1]. Significant examples such as establishing survival, proficient, active communication for emergency/rescue operations, disaster management efforts, and secured military networks [2]. ]. Vehicular Ad-hoc Networks (VANETs) can be considered as a subclass of Mobile Ad hoc Networks (MANETs) with some unique characteristics. Vehicles move on the roads sharing information
Abstract—The development in mobile devices and wireless technologies opens up unlimited choices of mobile services such as mobile commerce. These advances make access services available and convenient everywhere at any time. Since mobile users usually move, accessing services becomes unavailable especially in some locations that are not covered by their home networks. Therefore, it becomes necessary to roam into foreign networks in order to access such services. However, authenticating visiting users

Battery Span and Talk time Having a wireless hearing device does put you in an advantageous position as the user does not have to sit in one position and use it. Instead, he can move about and use the headset in a comfortable manner. However, if you end up with a wireless headset that does not have a good battery life; you would be spending half of your day in recharging it. The users of Plantronics Voyager Edge definitely do not fall in this category and they do not have to go through the trouble
