Question 1: Discuss what a wireless network is. What concerns should be understood about data communications being sent over wireless networks? Discuss the pros and cons of one current method of wireless data communication transmission. Answer: Answer all the 3 questions. Use APA format with more than 400 words and at least 3 references Question 2 : Response by: Harishkumar Communication is the process of conveying information from a transmitter to a receiver, through a channel. The transmitter generates a signal containing the information to be sent. Upon transmission, the signal propagates to the receiver, incurring various types of distortion captured together in what is called the channel. Finally, the receiver observes the distorted signal and attempts to recover the transmitted information. The more side information the receiver has about the transmitted signal or the nature of the distortion introduced by the channel, the better the job it can do at recovering the unknown information. There are two important categories of communication: analog and digital. In analog communication, the source is a continuous-time signal, for example, a voltage signal corresponding to a person talking. In digital communication, the source is a digital sequence, usually a binary sequence of ones and zeros. A digital sequence may be obtained by sampling a continuous-time signal using an analog-to-digital. A signal is a function that describes how a physical or a nonphysical variable changes over time and/or space. Signals are usually acquired by sensors and transformed by a transducer into an appropriate form to be stored, processed, or transmitted. For example, a microphone contains a diaphragm to capture the audio signal and a transducer to convert that signal into a voltage. In a wireless communication system, typical signals are the currents and the electromagnetic fields used to carry data from a transmitter to a receiver through a wireless channel. There are many other types of signals besides audio and communications signals: speech, image, video, medical signals like an electrocardiogram, or financial signals measuring, for example, the evolution of stock prices. Signal processing is a relatively new engineering discipline that studies how to manipulate signals to extract information or to change the characteristics of the signal with a given purpose. Though signal processing includes digital and analog techniques, DSP dominates most of the application scenarios. Therefore, an analog signal to be processed is discretized and quantized before manipulation. For example, the receiver in a wireless communication system has to apply some processing to the received signal to remove noise, cancel interference, or eliminate them distortion due to the propagation through the wireless channel; at the transmitter side, signal processing is used to generate the waveform to be transmitted and maximize the range or the amount of information per time unit that can be sent. The current trend is to perform all these operations in digital, placing an analog-to-digital converter (ADC) or a digital-to-analog converter (DAC) as close as possible to the receive or transmit antenna respectively. Answer : Please add your comments whether you accepting the response or against the response depending upon the question in more than 300 words. Below are additional suggestions on how to respond to your classmates’ discussions: · Ask a probing question, substantiated with additional background information, evidence or research. · Share an insight from having read your colleagues’ postings, synthesizing the information to provide new perspectives. · Offer and support an alternative perspective using readings from the classroom or from your own research. · Validate an idea with your own experience and additional research. · Make a suggestion based on additional evidence drawn from readings or after synthesizing multiple postings. · Expand on your colleagues’ postings by providing additional insights or contrasting perspectives based on readings and evidence. Question 3. Response: by Meet Shah As the word suggests wireless network is the network which don’t have any wires and can be connected to internet without any kind of physical cables. It helps in saving lot of money as users don’t need to pay for any kind of installation charges or buy any wires. Radio waves are used instead of cables to connect phones, laptops and even desktop computers to connect with internet. The most popular wireless technologies that are used in power distribution system are Wi-Fi (A usman & SH Shami, 2013). WiMax is one of the other evolution. WiMax is specifically designed for point-to-multipoint communications for both fixed and mobile applications; with data rates, up to 70 Mbps over a distance of 50 km. However there are various concerns by using wireless network for communication. Data can be stolen if the security is not up to date. It is tedious to setup a wireless network. Configuration can sometimes cause a lot of problem. If the user connects to a different wireless network unknowingly then it can be a major threat as it might give complete access to someone else. Some of the advantages of wireless networks are as follows: 1) Increase in efficiency 2) Portability 3) Less costly 4) Flexibility Some of the disadvantage of wireless networks is as follows: 1) Initial configuration 2) Security threats 3) Speed limit 4) Coverage (amount of area covered within the range of router) If a device moves too far from the router it might have some issues with speed Answer : Please add your comments whether you accepting the response or against the response depending upon the question in more than 300 words.

Question one

A wireless network describes a digital system that utilizes data connection to create a
connection between nodes of the net. The methods of wireless networking involve the application
of business installation and telecommunication networks to avoid the cost of buying and
introducing cables into the building. These wireless telecommunication networks are administered
and implemented by the use of radio communication. Implementation of wireless
telecommunication takes place at the most layer of the OSI model in network structure (Liu et al.,
2016). Some of the broadcast networks involve terrestrial microwave network, satellite
communication networks, wireless sensor networks, wireless local area network (WLANs), and
cell phone networks. The risk of attack over this network goes up when there is the deployment of
a local area network in all type of field.
There are several fundamentals that should be mind when deploying a wireless network.
First, we need to understand how and what frequency is used by the deployment’s equipment.
Second, wireless technologies and mobile have a high trend since the introduction of the first radio
signal in the 1900s. Due to the introduction of this communication gadgets and devices, there is a
significant transformation in business and many cent...
