Optical Fiber Communication

Fibre Optics is a branch of electronics that deals with the transmission of light signals over long distances through optical fibers. Optical fibers are long and extremely thin strands like human hair made up of pure glass. A single optical fiber has the following main components:

  • Core – The thin glass center through which the travels.
  • Cladding – An optical material around the core for reflecting light back to the core.
  • Buffer coating – An outer plastic coating that acts as a protective shield around the fiber.

Thesis Topics in Electronics and Communication

Fibre Optics is a very good choice as a topic for the thesis and research in electronics and communication.

There are two types of optical fibers:

  • Single-mode Fibers – Have small cores
  • Multi-mode Fibers – Have larger cores

Fibre Optics is based on the concept of total internal reflection in which the ray of light is completely reflected from the surrounding surface in the given medium.

Advantages of Fibre Optics

Fibre Optics has several advantages when compared to traditional medium of transmission such as:

  • Higher Bandwidth
  • Less susceptible to interference
  • Lighter weight

MIMO-OFDM

It stands for multiple-input, multiple-output orthogonal frequency-division multiplexing and is the wireless communication technology used in 4G and 5G cellular standards. It combines the MIMO technology with OFDM for better communications at high speed. It is an advanced technology that can handle data rate of 1 Gbps and above and is the base for advanced wireless local area network(WLAN) and other mobile broadband networks. It is a hot topic for the thesis in electronics, particularly in wireless communication.

In MIMO technology, multiple antennas are used at both ends of the wireless links to improve the spectral efficiency and link reliability in the communication systems.  OFDM combines modulation and multiplexing techniques and is a multicarrier block transmission system in which block symbols are grouped together and sent parallelly.

Advantages of MIMO-OFDM

  • Better quality of service
  • Spectral efficiency
  • High data rates
  • Reduction in interference
  • Spectrum utilized to maximum
  • Number of carriers are more
  • Reliability of the link
  • More flexible network

The implementation of MIMO-OFDM is based on the Fast Fourier Transform(FFT) algorithm as well as MIMO encoding.

Wireless Local Area Network(WLAN)

Wireless Local Area Network or WLAN is a wireless network in which users are connected to the local area network through a wireless connection. Wireless LAN technologies have been specified under the IEEE 802.11 group of standards. These standards use the Ethernet protocol and CSMA/CA protocol for communication and path sharing. In WLAN, a wireless router acts as a base station that provides connections to Wi-Fi-enabled devices.

There are various protocols used for building WLAN such as Bluetooth and Wi-Fi. The number of devices in the network can range from two to more than hundred as per the requirement. The devices can be mobile phones, laptop computers, or any internet-enabled device.

Topics in Electronics and Communication

Advantages of WLAN

  • Easy setup when compared to the wired network
  • It can support a large number of devices
  • Configuration is easy
  • Installation of the network is cost-effective

Disadvantages of WLAN

  • The network can be easily hacked
  • Any form of interference affect the stability of the network
  • In order to expand the network, there is a need for devices like repeaters
  • Power consumption is high

Security standards in WLAN

There are some WLAN security standards which are given as follows:

  • WEP (Wired Equivalent Privacy) – For data encryption
  • WPA (Wi-Fi Protected Access) – For higher security
  • 802.1x – To authenticate the wireless systems
  • WPA2/802.11i – To address different aspects of security

Wireless Sensor Networks(WSN)

Wireless Sensor Networks is one of the leading areas of research and thesis. It is a network of devices in which devices known as nodes have sensors to monitor their surrounding environmental conditions like temperature, sound, pollution, humidity, etc. The nodes communicate with each other through wireless links. The data is transferred to other networks via wireless Ethernet. The network consists of a base station and the sensor nodes.
