February 25th 2013 Benny Lane 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

3. PATH LOSS MODELS Path loss models play a vital role in planning of wireless communication systems. They represent a set of mathematical equations and algorithms that are used for radio signal propagation prediction in certain areas. Propagation path loss models are used for calculation of electromagnetic field strength for the purpose of wireless network planning during preliminary deployment. Path loss model describes the signal attenuation from transmitter to receiver antenna as a function of

TUTORIAL 5 1. List and describe three (3) major LAN topologies? Topologies can define as the layout of a network. There are really three basic types of topologies. They are Star‚ Bus‚ and Ring. In a star topology‚ all computers and devices are connected to a centrally located hub or switch. The hub or switch collects and distributes the flow of data within the network. It’s better to use a switch than a hub because a switch transmits the data to the intended recipient rather

Internet America is a wireless ISP (WISP) that operates within the southern United States. Currently we have been expanding the use of WiMAX hardware to provide our customer base a better user experience with fewer issues. Our older hardware has become unusable due to the vendor being restricted from sales in the United States so we made the recent decision to utilize WiMAX hardware developed by an Israeli company. This has brought on the added challenge of maintaining the hardware in the event of a Middle
