Here in this post, we discuss related to Types of Wireless Communication and where this will help in our life. This all provides an important role in our life and makes our life very easy. We thank IoT (Internet of Things). Let’s first see all the types and after that, we go into depth for a brief idea.
Types of Wireless Communication :
1. Television and Radio Broadcasting
2. Satellite Communication
4. Mobile Telephone System (Cellular Communication)
5. Global Positioning System (GPS)
6. Infrared Communication
7. WLAN (Wi-Fi)
9. Radio Frequency Identification (RFID)
This is all we used anywhere but we don’t remember and focus on that. Now we get an overview of some of the most useful applications.
Wireless Communication System :
wireless communication system definition said Framework utilizes radio-recurrence, infrared, microwave, or different kinds of electromagnetic or acoustic waves instead of wires, links, or fiber optics to send transmissions or information. We know that there is a vast difference between wireless communication vs wired communication. Because in a wired Communication Network there exists an actual media between the transmitter and the collector utilizing which the transmission is moved. In Wireless Communication System, there exist no actual media between the transmitter and the collector.
wireless communication technology communicates data over the air utilizing electromagnetic waves like IR (Infrared), RF (Radio Frequency), satellite, and so forth. There are billions of wireless communication devices currently available in the world. Wireless communication and network is a gathering, or organization, of various gadgets where information is sent and gotten over radio frequencies.
Radio Frequency Identification (RFID) :
Radio Frequency Identification (RFID) alludes to a remote framework that involved two parts: labels and perusers. A peruser is a gadget that has at least one receiving wire that radiates radio waves and gets signals back from the RFID tag. The best radio frequency identification example is we all go into the mall and purchase the things after the cash counter person scans the barcode and the entry of that product will automatically be added to the bill it will through RFID.
In radio frequency identification technology, there are mainly two components one tag and another reader. In this radio frequency identification device using radio waves, they will identify people or objects.
For radio frequency identification security purpose RFID is useful in many big organizations and gain efficiency. One common problem is that RFID is fitted in the small device so security will not be mainly provided in that.
Satellite Communication :
satellite communication definition says that by utilizing radio waves to convey messages to the receiving wires on the Earth. The receiving wires then catch those transmissions and interact with the data coming from those transmissions. Satellite communication frequency ranges from 4-8 GHz which will provide the best amount of communication facilities.
In the satellite communication introduction, A correspondence satellite is only a microwave repeater station in space. It is useful in media communications, radio, and TV alongside web applications. A repeater is a circuit, which expands the strength of the got sign and afterward sends it. Be that as it may, this repeater fills in as a transponder. The satellite communication ground station will communicate with the satellite and provide the information sent by the satellite. So, the main purpose of a satellite communication system is to gather data and study data on earth and space.
Radar Technology :
radar technology history began with tests by Heinrich Hertz in the late nineteenth century that showed that radio waves were reflected by metallic articles. This change was recommended in James Clerk Maxwell’s fundamental work on electromagnetism.
RADAR means Radio Detection and Ranging and is a functioning transmission and gathering strategy in the microwave GHz range. Radar sensors are utilized for contactless discovery, following, and situating of at least one article through electromagnetic waves. If we talk about radar technology applications then in the Military, Space, Air Traffic controllers, and Remote Sensing environment, Space used this. With that, it will also provide the radar weather report where different parameter shows today or tomorrow’s weather.
With that if we talk about radar technology advancements and new applications then Multiple Inputs, Multiple Output (MIMO) systems, Digital Beam Forming (DBF) techniques, Active Electronically Steered Array (AESA) radar, millimeter wave radar, Passive Coherent Location Radar (PCLR) Systems, semiconductor Power Amplifiers (PA), Intelligent signal coding and radar Digital Signal Processing (DSP) have inspired many modern radar designs in recent times. Advanced applications are nanotechnology and semiconductor.
Mobile Telephone System (Cellular Communication) :
cellular communication definition says a type of correspondence innovation that empowers the utilization of cell phones. A cell phone is a bidirectional radio that empowers synchronous transmission and gathering. Cell correspondence depends on the geographic division of the correspondence inclusion region into cells, and inside cells.
We all used mobile phones and are aware of our mobile communication system. With that cellular communication frequency range are various like for three bands (800/1,900 MHz,900/1,800/1,900 MHz or 850/1) and four bands (800/1,900 MHz or 850/1, 800/1,900 MHz,900/1). There are different cellular communication advantages also like increasing the data storage capacity and offering voice and data service. There are different types of the cellular communication system.
- Mobile two-way radio
- Public land radio
- Mobile telephone and amateur radio
Global Positioning System (GPS) :
global positioning system definition says it is U.S.- possessed utility that gives clients situating, route, and timing (PNT) administrations. This framework comprises of three sections: the space fragment, the control portion, and the client section.
The Global Positioning System is a route framework utilizing satellites, a collector, and calculations to synchronize area, speed, and time information for air, ocean, and land travel. We all use GPS online live application and one of the known applications is Google Maps which will be used for the GPS tracking system.
The global positioning system (GPS) will offer various services and the global positioning system uses satellites and getting gadgets used to decide the area of something on Earth.
Infrared Communication Technology :
infrared communication technology is a remote portable innovation utilized for gadget correspondence over short ranges. IR correspondence has significant constraints since it requires view, has a short transmission range, and can’t infiltrate walls. IR handsets are very modest and act as short-range correspondence arrangements. If we talk about infrared communication range then it will be up to 30 feet.
Basically, an infrared communication system means remote sensing which requires a line of sight. Infrared communication applications are Remote for controlling television, Home Appliances, and stereos. Infrared communication advantages and disadvantages are described below.
Pros: simple, Not much Expensive, Limited Interception, Power Efficiency, and Extensive Application
Cons: Line of Sight Propagation required, Short Transmission rang, Security
