Wireless Communications, The Radio Industry

The COM-3011 operates by first mixing the received signal with 125 MHz, thus the data is now contained on it. The centre frequency is chosen by mixing a user specified radio synthesiser frequency with the 125 MHz together. For example to obtain a centre frequency of 100 MHz, the user would specify 225 MHz or -25 MHz. The bandpass filter will reduce the bandwidth to 40 MHz or 20 MHz either side of centre frequency [12]. This sample is the duplicated and the second part delayed by 90 degrees to form an in-phase and quadrature features.

Currently billions of mobile devices are connected to wireless networks and by the year 2020 when the massive arrival of 5G to the market is expected to be four times higher. This paper aims to analyze the advances in communication for these networks that will be present in all types of portable devices and personal use in addition to computers. It evaluates the progress for aspects of communication and ability to transfer data and information through new wireless networks. The benefits and improvements in communication and performance in different devices for 5G networks are evaluated; this 5G of wireless networks promises an excellent performance in the exchange of personal, business and institutional data, also this paper

The purpose of this project is to build a system that will help and address Tony Chip’s new requirements. All of the new requirements will be considered with the system architecture and it will use all of the applications that still perform after the upgrade and change. The

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

One of the most important contributions to communication is the invention of radio communication. It has provided a platform for wireless cellular communication. According to an article, it was first believed that ‘The wireless telephone will also cover the seas, lakes and waterways, supplementing the wireless telegraph over short distances’ (Burt, 1908, para. 3). If only he knew that wireless telegraph will become a thing of the past. The first effective radio communication system was developed by Guglielmo Marconi, an Italian inventor, and scientist (Guglielmo Marconi Biography, n.d.). Marconi never had any formal scientific education (Bababian, 1992), but ‘has been the recipient of honorary doctorates of several universities’ (Guglielmo Marconi - Biographical, 2013, para. 8). He began experimenting with electromagnetic waves in 1894 when he was twenty years old. However, ‘Nikola Tesla is now credited with being the first person to patent radio technology; the Supreme Court overturned Marconi's patent in 1943 in favour of Tesla. (Bellis, n.d., para. 6) ’.

This chapter presents about the FPGA ideas and FPGA Synthesis Flow. An FPGA is a device that comprises of thousands or even large number of transistors connected to implement logic functions. They implement functions from simple addition and subtraction to complex digital filtering and error detection and its correction.

Nowadays most technology is becoming wireless. These inventions are making our lives much easier, and in this fast-paced world we really need it. Although some of the technological developments are just making us lazy, like the remote control. Although it makes it easy for us, some people take advantage therefore it contributes to obesity. Most of the technology has been invented for the great demand on them, it has also helped medical advances. Wireless technology just helps makes our lives run by smoother, than if we still had everything wired.

Wireless technology has become the wave of the future. From cellular phones to wireless point of sale devices, wireless networks and technology is all around us. In order to jump on the wireless train, one must first understand the different standards. To properly and safely utilize wireless technology the user also must understand the various types of wireless security. Once grasping these technologies and standards, anyone can implement a wireless network in their home.

A growing expansion of wireless systems and applications operating at centimetre-and millimetre-wave frequencies motivates the development of effective and affordably-priced technologies for manufacturing cm- and mm-wave components like antennas, filters, directional couplers, etc. Advances in technology associated with signal processing, R.F. components and batteries have stimulated more innovative applications in wireless that has in turn stimulate for extensive research to find new solutions to the problems in the antenna engineering.

frequency offsets in the subcarriers, the orthogonality among the subcarriers breaks and this causes intercarrier interference (ICI). The second drawback, is that

With the advent of the System on Chip (SoC) devices like the Xilinx® Zynq® All Programmable SoC that combine the versatility of a CPU and the processing power of an FPGA,

In the last few years, number of mobile users/wireless users has been increased explosively all over the world. The demands for wireless communication network has been increased day by day and it cannot be satisfied with wired networks because it has been seen that communication channels are more contaminated than wired networks. The main characteristics of the wireless communication are the multipath reception. We can receive signal not only through Line of Sight but also reception can be made through a large number of reflected radio waves that arrive at the receiver at different times. The difference in arrival time is caused due to trees, vehicles, buildings, rocks etc.

The ATMEL, ATMEGA328 is a is a low-power CMOS 8-bit microcontroller based on the AVR enhanced architecture. By executing powerful instructions in a single clock cycle, the ATmega328 achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.

Wireless technology is a booming business that is finding far reaching benefits on a global level. Corporations, schools, homes, and cafes are implementing wireless solutions as individual organizations and users seek more freedom and constant access. Wireless Fidelity (WiFi) is the latest buzzword to capture the market in our individual quest for access anywhere at any time. All of this comes at a price. Security is a major concern moving forward, as well as having too much access that does not lead to needed personal downtime. In the end what is more valuable, access or secure access at the right time?

A Brain-Computer Interface is a communication and control system in which human mind can be translated to the external world without the help of the normal output pathways of muscles and nerves. Each time we do something or think about doing something, our brain generates distinct signals. These signals corresponding to an activity, has a pattern. Finding this pattern is a challenging job and is the main task of any Brain-Computer Interface. A BCI acquires these signals from the brain of a user in the form of Electroencephalography (EEG). Then after pre processing, feature extraction and classification, it translates these signals into meaningful commands or instructions to drive a device or application. Electroencephalography is used to record electrical fields that represent the brain signals and are generated due to the local brain function.
