Concept Of Wireless Networking Essay

Question:

Discuss about the Wireless Networking Concept.

Answer:

The radio frequency and the AC currents are basically the information stored in form of data (Song, Nuaymi & Lagrange, 2016). If there is certain information and it has to be transferred to the larger distances and in all the direction the radio waves are used. Yagi antennas are used in television, and cannot be used for the long-range transmission and long frequency. It is used for using only one frequency. This antenna includes a reflector, single driven element and single or multiple directors. The Yagi antenna has a dipole for the main radiation of the diving element. Yagi, Horn and cellular antennas are the some of the antenna used for different purposes.

Strength

This antenna is responsible for lowering the strength of the signal for gaining the antenna frequency range.
The antenna can ascend on vertical poles and on similar type of poles.
It has a high gain allowing lower strength signals for receiving (Abdulhamid, 2017).
This antenna is useful in the RF antenna design applicable that requires high gain and directivity. This helps in gaining the optimum reception and transmission conditions.

Weaknesses

There are some weaknesses of the Yagi antenna in the market. These weaknesses are described below:

The antenna cannot gain high levels frequency. Fir achieving it, the antenna becomes very long.
The limit of the gain for the Yagi antenna is around 20dB (Li et al., 2016).
Yagi-Uda arrayor Yagi antenna is directional antenna it is used for the communication for the frequency, which is over 10 megahertz.

Horn antenna

The radio waves of the Horn antenna transmit or radiates the vacuum space and the antenna helps in transmitting structure of both impedance of tube and vacuum space is checked during transmission (Jariyatantiwait & Yen, 2016). The data is converted into the radio frequency so that it can be transferred to the large distances and in all directions. The antenna is divided in five prototypes including exponential, sectorial, pyramid, corrugated and conical. The size of the horn is very crucial for sending and receiving the signals. Horn antenna as dipole antenna can minimize the loss of the energy around the edges of the reflector moreover it also minimize the unwanted signals (Dahiya & Gill, 2016).

Strength

The horn antenna provides a better experience and efficient performance.
The horn antenna gain up to 25dB.
The antenna functions over a broad extent of frequencies and bandwidth.

Microstrip antenna

The microstrip antenna is used in the masses and us a lightweight material. It is very eas1y to install in the electronic device (Kitsos, 2016). This antenna can be used in the missile system, GPS, satellite connecting and mobile. Therefore, it is used in a wide range of products in the world.

Advantages

There are various advantages of the microstrip antenna in the market.

The antenna has an easy install configuration and generation.
It has a low cost budget for the customers.
These antennas have a potential radiators system installed in it.
The antenna is beneficial for both indirect and direct circular polarization effect.
This antenna can be easily be collaborated with microwave incorporated circuits.
The FDMA and CDMA are two basic type of wireless communication. The multiple access system is used in mobile system transmission. The infrastructure and design of FDMA (Frequency division multiple access) is separated into multiple frequency small bands or the sub frequency bands. The FDMA terminals includes frequency of its own. The signals of the FDMA technology is generated through the filer process in the frequency domain.

FDMA Infrastructure and design is installed in frequency band that are separated in the multiple distinct small frequency bands and sub frequency bands.

FDMA terminals

Terminals of FDMA have its frequency that helps in maintaining the continuation fashion.

Signal Prepare

FDMA signals are generated by filtering the frequency domain.

FDMA basic advantage

FDMA is relatively simple, easy to install, configure, and full of elegance

FDMA disadvantage: The frequency available through FDMA is not adequate and frequency is rigid in nature.

Other features: FDMA is sometimes combined with SDMA, TDMA for better consequences.

CDMA

CDMA stands for Code Division Multiple Access that is major radio systems used in cell phones. The infrastructure and design of CDMA is the expansion of the spectrum by applying the orthogonal codes. The terminals of CDMA can be made active all at once. The signal is generated in CDMA is through the specially designs codes and receivers. The advantage of using CDMA is that it is easily adaptable in nature and can be easily installed with less planning. The disadvantage of using CDMA as users of CDMA increases the quality of the service decreases and it get self-jammed.

CDMA infrastructure and design: CDMA is designed via expanding the spectrum by employing the orthogonal codes.

CDMA terminals: All the associate CDMA terminals all at once can be made active in a continued fashion.

CDMA signal generate: CDMA signals can be generated by specially designed codes and specially designed receivers.

CDMA basic advantages: CDMA is easy adaptable in nature, requires less planning.

CDMA disadvantages: The receivers are complex in nature and more complicated power control is necessary for the senders.

Other features: CDMA is combined with the FDMA and TDMA can give better consequences though this combination procedure is little bit complicated.
