List of the 7 Different Wireless Communication Technologies
Wireless-Technology refers to the transfer of information through electromagnetic waves like IR, RF, satellite, Bluetooth, NFC, etc. In fact, most devices today use wireless-technology and there are also various wireless-communication-devices that can allow different devices to communicate wirelessly in remote areas. So, in this article we are going to list the 7 different types of wireless communication used today;
List of the 7 Different Wireless Communication Technologies:
- Infrared Wireless Communication: This is a type of wireless-communication where information is transferred between different devices through IR-radiation. In fact, IR is an electromagnetic energy with a wavelength longer than that of red light. On the other hand, in the electromagnetic spectrum IR-radiation lies between microwaves and visible light. Infrared-Technology is used in security control systems, TV-remote controls and other short-range communications. Lastly, the normal frequency of an infrared broadcast system is 100 GHz to 1,000 THz with a limited speed of 1-Mbps.
- Satellite Wireless Communication: This is a self-contained wireless communication technology that is widely spread all-over the world in-order to keep users connected almost anywhere on earth. This wireless-technology works in such a way that when a signal (beam of modulated microwave) is sent to a nearby satellite, it amplifies the signal and sends it back to the antenna-receiver that is located on the surface of earth. In fact, Satellite communication contains two main components which include; space-segment that consists of fixed mobile transmission, reception and ancillary equipment and space-segment which is actually the satellite itself. On the other hand, portable satellite phones and modems have more powerful broadcasting abilities than cellular-devices but satellite-phones are very expensive too.
- Microwave Wireless Communication: This type of wireless communication uses radio-waves to transmit information/data and the wavelength of radio-waves is measured in centimeters. Additionally, with this type of wireless-communication data/information can be transferred using 2-mehtods which include; satellite-method and terrestrial-method. So, with satellite-method information can be transmitted though a satellite that orbits 22,300 miles above the earth and the stations on earth will be able to send and receive data signals from the satellite with a frequency ranging from 11GHz-to-14GHz and a transmission-speed of 1Mbps-to-10Mbps while the Terrestrial-method uses 2 microwave-towers with a clear line of sight between them in-order to ensure that no obstacles disrupt the line of communication. In fact, the frequency range of a terrestrial-system is 4GHz-to-6GHz and with a transmission-speed between 1Mbps to 10Mbps. lastly, microwave wireless technology is often used purposes for privacy.
- Broadcast Radio Wireless-communication: open radio communication is the first wireless communication technology and it’s still being used today. Technology uses handy multichannel-radios that allow users to speak over short distances coupled with citizen’s band and maritime radios that offer communication services for sailors. Additionally, with audio broadcasting services, the radio broadcasts sound through air as radio-waves to a receiving antenna. In fact, a broadcast can happen either in simulcast or syndication or both and radio-broadcasting can also be done via cable-FM, internet and satellite. On the other hand, Ham radio enthusiasts can share data and function as emergency communication aids during disasters using their powerful broadcasting gear and can even communicate digital information over a radio frequency spectrum. All in all, radio-waves are electromagnetic signals that are transmitted by an antenna and these waves feature completely different frequency-segments whereby the user will be able to obtain an audio signal by changing into a frequency-segment. Lastly, the transmission frequency for information transmitted through a radio system ranges from 10-kilohertz (kHz) to 1-gigahertz (GHz).
- Wi-Fi (IEEE 802.11x): This is a low-power wireless communication that is being used on various electronic-devices like Smartphones, laptops, smart-home appliances and a lot more. With this type communication, a router acts as a wireless communication-hub that allows users to get connected only within close proximity to the router. On the other hand, Wi-Fi networks must be protected with passwords for the purposes of security or else anyone will access the Wi-Fi network.
- Bluetooth Wireless-Technology: Bluetooth technology allows you to connect a various electronic-devices wirelessly in-order to transfer and share data. In fact, Bluetooth technology has various functions and that’s why it’s the most commonly used wireless-communication technology on the market today. For example; Cell-phones can be hands-free earphones, mouse or wireless-keyboard via Bluetooth technology in-order transmit information from one device to the other device.
- Mobile Communication Systems: Mobile-phones can actually allow users to communicate across a single frequency-band through wireless-signals. In fact, cell-phones have a larger range of networks to provide good coverage but cordless phones also have limited signal-range and that’s why some Smartphones uses signals from satellites to communicate just like GPS-devices.
- ZigBee: This is a wireless communication standard designed to address the needs of a low-power, low-cost wireless sensor and control-networks. ZigBee wireless-communication can actually be used anywhere because it’s very easy to implement and requires little power to operate. All in all, ZigBee was developed to look into the needs of wireless-communication of data with a simple structure like sensors.
