Access Techniques in Wireless Communication Access techniques allow multiple users to share the same frequency band without interference. Here are some key methods used in wireless communication: 1. Frequency Division Multiplexing (FDM): - Description: Signals are transmitted simultaneously on different frequencies. - Example: Radio broadcasting, where each station is assigned a unique frequency range. - Drawback: Channels are reserved for users continuously, regardless of usage, making it inefficient for mobile communication. 2. Time Division Multiplexing (TDM): - Description: Signals are sent on the same frequency but at different time slots. - Example: Public Switched Telephone Network (PSTN). - Drawback: Similar to FDM, channels remain allocated to users even when not in use. To overcome the inefficiencies of FDM and TDM for mobile communications, multiple access techniques were developed: 3. Frequency Division Multiple Access (FDMA): - Description: Similar to FDM, but channels are not reserved. They become available to other users once a call is finished. 4. Time Division Multiple Access (TDMA): - Description: Similar to TDM, but channels are shared among multiple users who take turns transmitting in different time slots. Combined Techniques: - TDMA/FDMA: This combination allows for more efficient use of channels by limiting the number of simultaneous users. It is widely used in GSM networks. Important Note: TDMA is rarely used alone in wireless communication. When referenced, it typically implies the combined TDMA/FDMA approach.

A Yagi-Uda antenna, commonly referred to simply as a Yagi antenna, is a type of directional antenna that is widely used for communications and broadcasting. Here are its main characteristics and components: Components 1. **Driven Element**: This is the active part of the antenna, usually a dipole, which is connected to the transmission line (coaxial cable) and receives or transmits the radio waves. 2. **Reflector**: Positioned behind the driven element, the reflector is slightly longer than the driven element and serves to reflect radio waves back toward the driven element, enhancing the signal in the desired direction. 3. **Directors**: These are elements placed in front of the driven element. They are typically shorter than the driven element and help direct the radio waves, focusing the antenna's beam in a specific direction. Design and Function - **Directional**: The Yagi antenna is highly directional, meaning it can focus radio waves in a particular direction, which makes it very efficient for point-to-point communication. - **Gain**: The design of the Yagi antenna allows it to have a higher gain compared to simpler antennas like dipoles. Gain refers to the ability of the antenna to focus energy in a particular direction. - **Polarization**: It can be oriented to be either horizontally or vertically polarized, depending on the application. - **Frequency Range**: Yagi antennas are commonly used in the VHF (Very High Frequency) and UHF (Ultra High Frequency) bands but can be designed for a wide range of frequencies. Applications - **Television Reception**: One of the most common uses of Yagi antennas is in rooftop television antennas. - **Ham Radio**: Amateur radio operators use Yagi antennas for long-distance communication. - **Wi-Fi and Wireless Communications**: Yagi antennas can be used to extend the range of Wi-Fi networks or other wireless communications systems. Advantages - **High Gain**: The directional focus allows for greater gain, improving signal strength and quality. - **Simplicity and Cost**: Yagi antennas are relatively simple to construct and are cost-effective for the performance they provide. Disadvantages - **Directional Nature**: While beneficial in many contexts, the directional nature means the antenna must be precisely aimed, which can be a limitation in some applications. The Yagi-Uda antenna was invented by Shintaro Uda and Hidetsugu Yagi in Japan in the 1920s, and it has since become one of the most popular antenna designs due to its effectiveness and relatively straightforward construction.

Radio Communication. Two way radio communication has been in existence since the invention of the first radio transmitters. The proper language used in this form of communication is known as radio voice procedure. The requirement for a structured set of rules to facilitate radio communication stemmed from; the unsecured nature of most early age transmitters which could not yet encrypt radio transmissions, the necessity to recognise the caller’s and recipient’s i.d and to mark the end of radio transmissions to avoid chaos when two transmitters try to send at once. To overcome these challenges a set of rules to provide: security, accuracy and discipline to radio communication was formulated. These procedures were intended to bring order and secure radio communication networks. Two way radios are both transmitters and receivers hence the name (transceivers) which means they have the capability to send and receive radio signals. The use of multiple tranceivers in communication introduces the need for a coherent radio network to link communication amongst these tranceivers. Thus a radio network is a group of radio tranceivers communicating under a common frequency. The radios are assigned user i.d which is known as a call sign and for multiple radio networks, individual nets are assigned radio net identification signs(NIS).Modern digital radio tranceivers still use this concept to synchronise communication across multiple radios and radio networks with advancements in the encryption of radios signals through a variety of fancy features such as frequency hopping, Synchronised transmission and reception speeds, standardized and patented encryption keys among others. However even with the progress in tranceivers technology, the significance of securing radio transmissions through radio voice procedure must not be overlooked, since the human factor is still primary in radio communication. Therefore for the safeguarding of information transmitted over the radio lies the assumption that for every radio transmission, there are three parties. Two of which are intended and one who is an outsider looking to intercept and exploit information from the transmission.

Unguided media It is also known as wireless communication media refers to communication channels that transmit data without the use of physical connectors or guided pathways (like cables or wires). Instead, unguided media relies on electromagnetic waves to propagate signals through the air or space. This type of media allows for greater flexibility and mobility in communication, making it ideal for a variety of applications. Types of Unguided Media 1. Radio Waves: -Description: Radio waves are a form of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. They are commonly used for communication, including broadcasting, mobile phones, and Wi-Fi. -Applications: AM/FM radio, television broadcasting, Bluetooth devices, and cellular networks. 2. Microwaves: -Description: Microwaves are high-frequency radio waves that can carry large amounts of data over long distances. They require line-of-sight between the transmitter and receiver, which may necessitate relay stations. -Applications: Satellite communications, point-to-point microwave links, and certain wireless internet services. 3. Infrared: -Description: Infrared communication uses infrared light to transmit data over short distances. It requires line-of-sight and is often used when less interference and high security are desired. -Applications: Remote controls for TVs and other devices, wireless data transfer between devices (like infrared printers), and some short-range communication systems. 4. Visible Light Communication : -Description: A newer form of communication that uses visible light to transmit data. It can be implemented using LED lights to transmit data by modulating the intensity of the light. -Applications: Li-Fi (Light Fidelity) systems, which offer high-speed wireless communication in environments where radio frequencies are unsuitable. Advantages of Unguided Media: -Mobility: Devices can move freely within the range of the signal without physical restrictions imposed by cables. Ease of Deployment: Setting up wireless networks generally requires less infrastructure than wired networks, making them suitable for rapidly changing environments. -Flexibility: Wireless networks can easily adapt to changes, such as adding new devices or changing locations without significant redesign. Disadvantages of Unguided Media -Interference: Wireless signals are susceptible to interference from obstacles (like buildings) and other electronic devices, which can degrade performance. -Limited Range: Most unguided media have a limited range compared to guided media. Signal strength decreases with distance, making re-transmission or relay stations necessary for longer distances. -Security Risks: Since unguided media transmits signals through the air, they are more vulnerable to unauthorized access and eavesdropping than wired connections.
