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.

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.

The Wireless Planning & Coordination (WPC) process involves the regulation and management of the radio frequency spectrum in a country to ensure efficient, interference-free wireless communication. In India, the Wireless Planning & Coordination Wing (WPC) operates under the Ministry of Communications and is responsible for managing the spectrum, granting licenses, and coordinating among stakeholders. The WPC process includes several key steps: Key Steps in the WPC Process: Spectrum Allocation and Assignment: The WPC allocates and assigns the radio frequency spectrum for various services, such as mobile communications, broadcasting, satellite communications, and more. The spectrum is assigned based on the National Frequency Allocation Plan (NFAP), which specifies the allocation of frequency bands for different services. Licensing: The WPC grants licenses for wireless equipment and services to ensure compliance with regulatory requirements. Licenses include Import Licenses (for importing wireless equipment), Dealer Possession Licenses (DPL), and Non-Dealer Possession Licenses (NDPL) for entities dealing with wireless equipment. Operating Licenses are also issued to users for specific frequency bands and services, such as VSAT, microwave, and mobile services. Type Approval and Equipment Certification: WPC certifies and approves wireless equipment to ensure it meets the technical and safety standards for use in the country. The Equipment Type Approval (ETA) is a mandatory certification for wireless devices that operate in de-licensed frequency bands. For licensed frequency bands, the equipment needs to comply with more specific technical regulations. Interference Management and Frequency Coordination: The WPC coordinates with various national and international agencies to manage and mitigate radio frequency interference. It works to harmonize spectrum usage to prevent interference among different services, such as terrestrial, satellite, and broadcasting services. Monitoring and Enforcement: The WPC monitors the use of spectrum to ensure compliance with the terms and conditions of licenses. It also takes enforcement actions in case of unauthorized or illegal use of spectrum, including issuing fines or revoking licenses. Coordination with International Bodies: The WPC collaborates with international organizations like the International Telecommunication Union (ITU) and neighboring countries to manage cross-border spectrum issues and align with global spectrum management practices. Policy Formulation and Recommendations: The WPC also plays a key role in formulating policies related to spectrum management, including recommendations on the release of spectrum for new technologies and services. #Corpbiz

Modulators vs. Demodulators: The Architects of Wireless Communication In the world of wireless communication, information often needs to be carried over long distances. But how do we effectively transmit that information, whether it's a voice call, a streaming video, or data from a sensor? The answer lies in the dynamic duo of modulators and demodulators. Modulation: Imagine trying to shout across a noisy room. It's hard to be heard, right? Modulation is like using a megaphone. It takes your information (the "message") and combines it with a carrier signal (the "megaphone") to make it easier to transmit. This carrier signal is usually a higher frequency wave that can travel longer distances. Modulation techniques vary, including amplitude modulation (AM), frequency modulation (FM), and various digital modulation schemes. Think of it as encoding your message onto the carrier wave. Demodulation: Now, how does the receiver understand the message amidst all the noise? That's where demodulation comes in. It's like having someone who can understand the megaphone's message and translate it back into the original information. Demodulation extracts the original information from the modulated carrier wave. It's the reverse process of modulation, essentially decoding the message. Here's a simple analogy: Imagine sending a letter by carrier pigeon. The information (the letter) is your message. The pigeon is the carrier signal. Modulation is like attaching the letter to the pigeon's leg. Demodulation is like someone at the receiving end taking the letter off the pigeon's leg and reading it. Key differences summarized: FeatureModulatorDemodulatorFunctionCombines information with a carrier signalExtracts information from the modulated carrierActionEncodes information onto the carrierDecodes information from the carrierLocationTransmitterReceiver Export to Sheets Why are they important? Modulation allows us to: Transmit information over long distances: Higher frequency carrier waves travel more efficiently. Minimize interference: Modulation techniques help reduce the impact of noise. Transmit multiple signals simultaneously: Different signals can be modulated onto different carrier frequencies. Demodulation ensures that the receiver can accurately retrieve the intended information from the complex mix of signals in the airwaves. From radio and television broadcasts to cellular networks and Wi-Fi, modulators and demodulators are essential components in virtually all wireless communication systems. They are the unsung heroes that enable us to connect and share information seamlessly. What are some interesting modulation/demodulation techniques you've learned about?

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.

Hey dudes..... Here is a article based on the History of Electronic Communication,hope it will be more useful to everyone....Let's get started.... The history of electronic communication began in 1729 when Stephen Grey discovered that electricity could be transmitted over large distances using insulated metal wires. Since then the development of it has continued and become more rapid as time has gone on, helping shape the world as we see it today. From the first telegraph to the modern day fibre optic and satellite communications we have today, this website explains the development of electronic communication. Electronic communication systems have been a growing entity over the years. It evolved from generation to generation from using pigeons to carry messages in the ancient period to using morse code in telegraph in the mid-1900s to using 5G smartphones in the current generation. Communication System in Electronics Sending, receiving, and processing data among two devices are referred to as communication. A communication system is a group of components (devices) that work together to establish a connection between both the sender and recipient. Radio and television, satellite broadcasting, wireless telegraphy, mobile communication, and computer communication are some examples of communication systems. Principles of Electronic Communication Systems Information is transmitted, processed, and received among two or more points using electronic circuits. Transmitters, communication channels or channels, a receiver, and noise make up the fundamental parts of such an electronic communication system. Analog or digital data is conveyed into the system, where it is first analysed and decoded.
