COGNITIVE RADIO SYSTEMS

Cognitive Radio System is a form of wireless communication in which a transceiver detects the communication channels which are in use and which are not in use.

The Cognitive Radio Network (CRN) is broadly classified into two major networks, a primary network and a secondary network. Cognitive Radio users are unlicensed users and they used to find unused licensed spectrum for their own use without causing any interference to licensed users.Click here to continue reading

Broadband wireless communication

Wireless broadband:

Wireless broadband is nothing but a telecommunications technology which provides high-speed wireless Internet access or computer networking access over a good area. The term is both fixed and mobile broadband.The word “broadband” features a technical meaning, but it became a marketing term for any sort of relatively high-speed network or Internet access technology. Click here to continue reading

SOLAR POWER SATELLITE

 

INTRODUCTION:

The solar energy Satellite System may be a concept to gather alternative energy in space, so transport it to the surface of the planet by microwave (or possibly laser) beam, where it is converted into power for terrestrial use. The recent increase in energy costs, predictions of the near-term exhaustion of oil, and prominence of possible temperature change are the effects of the "greenhouse effect" from burning of fossil fuels.Click here to continue reading

Wireless Home Security System

Hello readers, welcome to another day of reading. In this segment we’ll be seeing about the outline of “Wireless Home Security System”. With the continuous growth in IT and network, it has become more and more possible for us to automate things around us. By combining wireless sensor network(WSN) and GSM technology we can easily secure our home.Click here to continue reading

RF Power Detector

 

All RF devices and equipment should carefully observe and control their transmit power to obey with wireless communication standards and reduce RF interference with other radio devices. Power of RF signals in transmit/receive chains in wireless communication systems is measured by RF power detectors.Click here to continue reading

RF Based Smart Home Automation

 In this technological advance era, automation is a necessity. Automation is the use of technological appliances to perform a task with minimum human input. The automation of the home is called as smart home. Smart home Automation makes the lives easy of humans by monitoring the data, providing safety, and maximizing the efficiency of the resources used in our homes and increasing the convenience to manage our homes. The devices used in the smart homes are mostly Radio Frequency (RF) based communications methods between devices.Click here to continue reading

RF CONTROLLED ROBOTIC VEHICLE

In this modern era, all people know about robots. Robots are machines which reduces the human efforts in heavy works in industries and many other domains and makes life easy. In this blog, what is RF controlled robotic vehicles and how it works is explained clearly. This RF controlled robotic vehicle, Microcontroller is not required for operating this robot, it makes use of Radio Frequency(RF) decoder and motor driver.Click here to continue reading
