2. Answer the following four questions on your Lab Report relating to the signal coverage image above. Question 1: Discuss how changing the type of antennas affects the amount of signal spilling outside the building. What are your recommendations? Question 2: Discuss how relocating the access points to a different part of the building affects the amount of signal spilling outside the building.
Yes, it is a signal from the three unliscensed frequency ranges. 5. If it is, what type of signal is this, 900 MHz, 2.4GHz, or 5 GHz? The signal operates in the 2.4 GHz frequency. 6.
Calculate the impedance by the measured values of voltage and current from the oscilloscope. Also calculate the impedance from = − C. Answer: Impedance, Z = 5∠0 34.65 60.48°) = 173.25 - 60.48⁰ = 85.37 Ω - j150.76 Ω Again, XC = 1/ = 1/ (6280 x 10-6) = 159.24
Figure 2 shows a circuit with a resistor R = 1.0 × 103 Ω, and a battery with potential difference of VB = 5.0V . (a) Solve the circuit in Figure 2. That is, find all unknown currents, voltages, and resistances. (b) What is the direction of the current? Note: I want the direction of the conventional current.
Unit 1. Assignment 1. Voice vs. Data Cell Phones Known as a mobile a phone it can make and receive telephone calls over a radio link while moving around a wide geographic area. Modern mobile phones support a wide variety of other services such as text messaging, email, internet access, Bluetooth, gaming and photography. Landline phones is a phone that uses a solid medium telephone line such as metal wire or fiber optic cable for transmission.
Jamarquis Green Written Assignment General Biology 4/13/14 1. Light is a form of energy known as electromagnetic energy it travels through rhythmic waves, the distance between the crests that become formed are called wavelengths these wavelengths range from less than a nanometer which is equivalent to a gamma ray which humans can’t visibly see too more than a kilometer which equivalent to radio waves the entire range of radiation is known as the electromagnetic spectrum which measures light. In plants light energy is used to convert solar energy into chemical energy what this means is that the heat from the light causes the plant to undergo different changes due to the heat that it has absorbed. Also light energy contains ample amounts
Specific questions from iLab Scenario 1 Discuss how changing the type of antennas affects the amount of signal spilling outside the building? What are your recommendations? The problem that arises from changing an antenna is that the outer lying areas of the network can lose their signal. One solution to this problem is to lower the antenna output power via the controls of the access point. However if that presents the same problem with loss of signal there are alternatives such as WiFi blocking wallpaper (Strange) or paints that will block the WiFi signal from leaving the building (Jowitt).
