Case Project 3-5 on p. 112 of the text.

Post your response to the following: Imagine you are the network administrator of aWLAN. Give an example of how knowing the 10’s and 3’s Rules of RF Math can helpyou on the job. Include your answers to Case Project 3-5 in your response. Show your work

The 10’s and 3’s rule are supposed to assist the network manager find the quantity of energy that is either received or lost in a wireless transmission. Different resources of RF interference may cause various stages of loss and gain. Therefore it is essential for one to understand the dB measurement to assist recognize the origin of interference.There are lots of things which may cause RF decrease for example refraction,reflection, diffraction, scattering, absorption.Reflection can cause a signal to bounce back on itself and so augmenting the signal.That is why it is essential to use a dB measurement to assist find the issue and what iscreating it.From the studying of our textual content I deducted that the dB of 1W is .So for the EIRP here's how I arrived at my judgment.9dBi = 3dBi X 3 and due to that the signal gain is increased by three times200mW X 2 = 400mW

    A wireless local area network, or LAN is a flexible data communications system implemented as an augmentation to, or an alternative for a, wired local area network. These networks rely on electromagnetic airwaves to transmit and receive over a defined area, usually a few hundred feet. (Yahoo-wireless) In most cases, a wireless transmitter will be connected directly to a wired land network using Ethernet cables. Once the network feed has been connected to the transmitter, and a constant power supply is established, a steady stream of radio, or infrared waves with be produced (both are electromagnetic waves). The vast majority of wireless LAN systems tend to rely on radio waves as the carries for their signals, because infrared waves tend to have a shorter distance at which they are able to transmit, and are more easily interrupted. Radio waves, or radio carriers as they are referred to, transfer data through modulations of the carrier signal. The addition of data to a radio carrier causes the signal to occupy more than a single frequency. Once data is imprinted onto the radio signal it is a simple reversal of the transmitting process that allows the information to be decoded by a receiving station. (Rho Wireless)…

    Wireless Signals

    Wireless signals are all around us as we walk or drive around the city or town where we live. The four types of wireless technologies that are out there are Wi-Fi, Cellular, Bluetooth, and WiMAX. We will be looking at these types of wireless technologies a little more in depth, where are they most commonly used, and how they differ from one another. The first wireless technology that we will be looking at is the Wi-Fi wireless signal. The Wi-Fi signal is mainly associated with computer networking, the specification used to create a wireless local area network is the IEEE 802.11. One would use this type of wireless technology if you were a business owner opening up a coffee shop and needed a public network. The network would have a wired connection to an internet source, then leading to a wireless router that transmits and receives the data from all of the customer’s devices that want to use the Wi-Fi. This will also connect all of the devices to one another through the network. The next type of wireless technology that we will be looking at is Cellular. This type of wireless technology is most often associated with wireless telephones. The cellular network is connected to cells that will enable a user to move around freely while staying connected to the network. This type of signal is used everywhere you go nowadays and are used by everyone. There are a multitude of devices that use these networks at one time and those include, smart phones, tablets, and some computers can use the cell towers to get a signal to be able to use the internet. The first generation of cellular signals was completely analog, and from there with the growing demand of faster speeds and better connectivity technology brought us 2G, 3G, and the ever popular 4G phones. Bluetooth is the next technology that we will touch on and is very similar to the Wi-Fi and cellular networks but on…

    Wired and Wireless, What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radio waves. Another difference and how one technology gets an edge over the other. Wired networks are easy to set up and troubleshoot where wireless networks are comparatively difficult to set up, maintain, and troubleshoot. Wired networks make you immobile while wireless ones provide you with convenience of movement. A third difference, wired networks prove expensive when covering a large area because of the wiring and cabling while wireless networks do not involve this cost. Wired networks have better transmission speeds than wireless ones. In a wired network, user does not have to share space with other users and thus gets dedicated speeds while in wireless networks, the same connection may be shared by multiple users. One of the most common questions we have to answer on a daily basis is the difference between wired and wireless networks. Wired is the communication between two devices via cables. Wireless is the communication between two devices without cables.…

    1. Introduction The increasing interest in wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and communicate in a wireless fashion, with the end goal of handing their processed data to a base station. Sensing, processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications [A1], [A2]. Sensor networks provide endless opportunities, but at the same time pose formidable challenges, such as the fact that energy is a scarce and usually non-renewable resource.…

    The use of mobile wireless technology in higher education generates questions regarding what advantages this new technology generates. Studies (Kim, Mims, & Holmes, 2006) talk about the efficiency and effectiveness in teaching and learning created by mobile technology. But what does this mean? Certainly we can be more mobile, but how does this benefit learning? First, mobile wireless technology lets us communicate more easily. This allows us to collaborate more easily with other students and with faculty. Discussing topics of study with others allows us to come in contact with other ways of viewing a problem and its possible solutions. The phrase “two heads are better than one” can be expanded through collaboration to “many heads are better than one”. This collaboration can be real time or asynchronously, whichever is more convenient at the time.…
