Answer: The reason of using Spread Spectrum Transmission: Wide range of bandwidth. It can eliminate crosstalk. Cost effective to use. The strength of power signal is high. Single bandwidth of spectrum can be used by the multiple users. Comparison and contrast of two methods of spectrum transmission: The two types of spectrum transmission is Direct Sequence Spread Spectrum (DSSS), Frequency Hopped Spread Spectrum (FHSS) Contra...Read More >>
Answer: Introduction: CCI stands for Co-Channel Interference which is defined as a method of crosstalk from two or various kinds of radio transmitter by making use of same frequency (Bellalta, 2016). There may be various reason behind Co-Channel interference. In some of densely populated area it may be possible to have an idea regarding the AP with other AP making use of same kind of channel. This will ultimately result in creation of Co-Chan...Read More >>
Answer: Introduction: The wireless network is the infrastructure less mobile network which is used for the communication with less interference of cables (Fitzek & Katz, 2006). The current report is based on the wireless network concepts that provide the different types of antennas including yagi, horn, cellular. Further, new three wireless protocols such as Wi-Fi direct, RFID (Radio-Frequency Identification) and 6LoWPAN (Lower Power Wire...Read More >>
Answers: Antenna An antenna is defined as an array of elements which are connected with transmitters or receivers. An antenna produced some electromagnetic waves in order to generate an electric current. The first antenna was developed by Heinrich Hertz in the year 1888 and he has produced a dipole antenna which can be used for both transmitter and receiver. An antenna is characterized as a transducer which is utilized to change over RF recur...Read More >>
Answers: 1. Description of Different Types of Antenna An antenna is a transducer that converts the electrical signal to the electromagnetic waves during the transmitting mode and vice versa in receiving mode (Potapov, 2013, September). This paper would research about the Yagi antenna, Cellular antenna and Horn antenna. It would discuss the uses of these antennas along with their strengths and weakness. Horn Antenna: The horn antenna is know...Read More >>
Answer: RFID7 and NFC RFID: RFID stands for radio frequency identification which refers to a technology where digital data encoded in RFID tags. It is quite similar as barcoding, as data form a label or tag are captured by compatible devices to store the data in the database. RFID comprised with RFID tags along with an antenna. RFID tags are capable of read outside the line of sight which is one of the notable advantages of this technology. T...Read More >>
Answer: Answer to question number 1 For any kind of short distanced between two different devices the “Near Field communication” or NFC is entrenched along with the NFC sensors. In order to transfer data from any device regardless of power sources a tag is used. At the same time the information transmission will not be completed successfully without the application of the small transmitter. The mechanism of NFC works in a si...Read More >>
Answer: Horn antenna This is a example of antenna wire that is mostly utilized in flaring, this is the change of the radiation effectiveness through using a wave control that has a long gap, this forms a startling cutoff in the gradual wave transformation. It is mostly utilized in UHF and SHF recurrence ranges(Gehrin,2016). During the change procedure, the beam is step by step changed into a radiation this increases its focusing s...Read More >>
