Question

For wireless networks, explain what the main components of a wireless network are and what side information may be added to the data to provide a reliable communication between these components.

Answer 1

In this question, we need to answer the main components of a wireless network and the extra information is required to be added for reliable communication
The wireless network can be defined as a computer network which is mainly used to transfer the data wirelessly. The main components of wireless network are listed below
End user device
The device which is used in the user end such as computers, laptops or any other wireless devices such as monitoring device or bar code scanner etc. These devices are actually used to transmit the sensed data wirelessly.
Radio NIC
These devices are creating a bridge between wireless device and the end user device so that the end used data can be transmitted to the wireless devices via Radio NIC module.
Access Pointer
This kind of delves are mainly used to communicate between the end user device and wireless device via a communication card. Typically, software architectures mainly used to control the access points while providing a wide range of management, security and installation.
Routers
The routers are mainly used to transfer the data packet between the networks. It mainly uses the internet protocol packet headers and routing tables for estimating the best path for each packet. This kind of system is very beneficial in small network arrangement.
Repeaters
The repeaters are mainly used to regenerate the network signal to enhance the range. In wireless network, the repeaters are not directly connected to the wireless devices however it received the signal and retransmit the signal after amplification.
Antenna
The last important part of the wireless network is the transmitting and receiving antennas. In most of the cases, these kinds of antennas are mostly omnidirectional antenna so that it can transmit the signal omnidirectional way.

For reliable data transfer, once the data has been received, the communication layer is broken down the data in small segment and adds a header on each data segment. Once the above-mentioned operation are performed for the segments, the corresponding segments are transmitted.
