Wireless Signals XXXXXXXX IT/242 March 3, 2013 XXXXXXX

Wireless Signals Technology in general is in a constant state of invention and development especially in the computer industry. Network technology has made much advancement over the last 10 or more years. Today networks are now wireless, able to transfer data at faster speeds, and new network technology has increased security. Wireless technology sends and receives digital signals transmitted through the air by electrometric waves.
Wireless Signal Types Microwave signals, Infrared Systems, Satellite Signals, and radio systems all have made strides in improving the signal speed and quality. Wireless signals have pros and cons that influence their commercial use and present day application. However, no matter the progress made with wireless signal frequencies they are always subject to interference from technologies limiting their effeteness. Microwave Signals Microwave signals transmit using electromagnetic energy. Microwave signals are used commonly in long distance telephone telecommunications, cellular phone networks, and television networks. Microwaves travel in a straight line the wave can be narrow beamed making it more effective for long distance transmissions. This technology when applied allows a network to establish a high bandwidth network connection between two points. Some companies may have two locations in a town or county. The lower atmosphere has little affected to signal quality, when linking two network locations. Satellite Signals Satellite signals are similar to microwave which require a direct line of sight to ensure proper transmission. Satellites require that a satellite is in geosynchronous orbit of the earth and receiver must be locked on satellites orbit at all times to maintain connection. Satellites can cover large areas since they are in high orbit they can relay signals through other

    They are an attractive media because require no physical "wire" to be installed, can penetrate walls, provide connectivity to a mobile user, and can potentially carry a signal for long distances. The characteristics a radio channel depend significantly on the propagation environment and the distance over which a signal is to be carried. Environmental considerations determine path loss and shadow fading (which decrease in signal strength as it travels over a distance and around/through obstructing objects), multipath fading (due to signal reflection off of interfering objects), and interference (due to other radio channels or electromagnetic signals).…

    There are many advantages to having diversity in a collaborative learning environment including age, religion, physical ability, gender, and sexual orientation. People with other perspectives on things can bring to the table a new way of thinking about things. This can allow a new form of thinking within in the group to come to an understating or agreement to help solve the problem or achieve a goal. It helps other people work together without looking at another person differently because of their background or appearance. I think that it helps bring our culture more together to not be so stereotypical about other people so we can all come to an understanding of one another and keep moving forward in whatever the case may be.…

    Communication satellites work non-stop 24 hours a day to keep the entire world linked together. Until recently NASA had been the only one's launching satellites, but now many private companies are benefiting from what a satellite can do. Once a satellite becomes geosynchronous, rotates with the earth orbit, a satellite is ready to work. It then beams messages to a ground station, the ground station receives these messages by using a device called a transponder. Which interrupts the message and then distributes it. By doing this satellite stations can than transport telephone service, data, or television transmissions to almost anywhere. These communication satellites are used for things like an overseas phone call or beaming 150 channels into your living room.…
