Basic RF Calculations The power emitted from wireless devices, especially in unlicensed bands, such as 2.4 GHz and 5 GHz, are regulated by the Federal Communications Commission (FCC). Wireless network professionals must calculate power levels (or RF signal strength) that are being transmitted by wireless devices to make sure their designs are complaint with FCC regulations. They also need to calculate power levels that are being received by wireless devices to make sure the signal is properly received

NT1310: Week 1 Data on Fixed Line vs. Cellular Debate Data transfer on fixed line telephone networks has been around for years, while transfer over cellular networks is relatively new. There are challenges, however, to having wireless communication be the ONLY medium for communication. In this Lab, you will explain the pros and cons to having a purely cellular network vs. having a purely fixed line network. Conduct research on both using the ITT Tech Virtual Library and the Internet. You will

oscillator it is helpful for the system [1]. The AC power is then transferred wirelessly through inductive coupling. In inductive coupling power is transferred between coils of wire by a magnetic field. Fig. 2 shows the block diagram for the wireless power transfer through inductive coupling. The transmitter and receiver coils together form a transformer. An alternating current (AC) through the transmitter coil (L1) creates an oscillating magnetic field (B) by Ampere's law. The magnetic field

The RFID is a developing technology that uses radio frequency electromagnetic fields to obtain data for tracking and identifying medical products and goods (RFID Journal, 2012). RFID technologies have two main components: a reader, a tag and the application that makes use of the data the reader reads on the tag (Caldwell-Stone, 2010). The reader can be simple or smart, stationary or mobile and it needs to be connected to a network, especially within an infrastructure that captures data from different

table. Bluetooth and Wifi. This technology facilitates the operation of sending images or videos to devices that may not be in the same place or that are separated by distance. The wireless systems provides greater comfort to the user because it is not necessary to use so many cables for the installation of a wireless computer Gps The GPS is a new accessory that can easily replace the compass commonly used by the sportsmen to achieve orientation. It gives us the opportunity to know exactly where

protocols are required to optimize the performance of WMNs. In the PHY layer, smart antenna, multi-input multi-output (MIMO), ultra-wideband (UWB), and multichannel interface systems are being explored to enhance network capacity and further enable wireless gigabit transmission. Recently, gigabit transmission resulting from a combination of MIMO and orthogonal frequency-division multiplexing (OFDM) has been demonstrated. MAC protocols based on distributed time-division multiple access (TDMA) and CDMA

QUESTION1 Power Problems Alternating current (AC), which is “food” to PCs and other network devices, is normally 110 volts and changes polarity 60 times a second (or 60 Hertz). These values are referred to as line voltage. Any deviation from these values can create problems for a PC or other network device. Power problems fall into three categories: * Overage * Underage * Quality Power Overage Problems During a power overage, too much power is coming into the computer. Power overage

Wireless Technologies and Networks Wireless Technologies and Networks in the work environment Learning about different forms of communication is always fun and also discussing things that will heighten technology is also great to talk about. When the team got together we had numerous discussions going about that ended up almost like a tree discussion where we obviously knew the base of the talk and then we climbed up the trunk and went into tangents like branches. All in all it was a great
