Advantages and Disadvantages of mmWave 5G
The Frequency Range 1 or sub-6 GHz and Frequency Range 2 or mmWave are two of the frequency specifications identified for 5G New Radio and thus, defined and allocated for 5G cellular network technology. Between these two, the mmWave specification maximizes the full network potential of fifth-generation wireless connectivity. Pros: Advantages of mmWave 5G Drastic […]
Advantages and Disadvantages of Sub-6 GHz 5G
The general 5G New Radio specification is divided into two categories of frequency bands: Frequency Range 1 or sub-6 GHz and Frequency Range 2 or mmWave. Sub-6 GHz 5G is specifically one of the two frequency specifications defined and allocated for fifth-generation cellular network technology. Pros: Advantages of Sub-6 GHz 5G Sub-6 GHz include electromagnetic […]
Advantages and Disadvantages of Z-Wave
Z-Wave is a wireless communication protocol based on mesh networking using low-energy radio waves around the 900 MHz frequency band of the electromagnetic spectrum. Devices equipped with a capability to use this protocol can wirelessly communicate with one another, thus enabling the implementation of smart and automated systems. Pros: Advantages of Z-Wave Wireless Communication Protocol […]
Zigbee Technology: Advantages and Disadvantages
Zigbee is a wireless mesh network standard based on the IEEE 802.15.4 specification for several wireless communication protocols used for personal area networks. First introduced in 1998 and standardized in 2003, as well as revised further in 2006 and maintained by the Zigbee Alliance, use-case applications center on small and low-power communication devices or other […]
UWB: Pros and Cons of Ultra-Wideband Technology
Ultra-Wideband or UWB technology is a wireless communication protocol that uses electromagnetic radiation within the very high frequency or VHF range of the electromagnetic spectrum for short-range and high-bandwidth wireless communication. Communication systems based on UWB use bandwidth that is several times greater than the minimum required to transmit data. The use of excess bandwidth […]
Infrared Communication: Advantages and Disadvantages
Infrared communication or IR communication is a specific type of wireless communication technology that uses infrared electromagnetic radiation for short-range and one-on-one communication between two devices. Notable applications include data transmission using the IrDA standard and free-space optical communication. Within the electromagnetic spectrum, infrared sits between microwaves and visible light, and occupies wavelengths between 700 […]
Pros and Cons: Bluetooth versus Wi-Fi Direct
Bluetooth and Wi-Fi Direct are used for wirelessly connecting two or more devices or transferring data between devices over short distances using electromagnetic radiation within the ultra high frequency or UHF band of the electromagnetic spectrum. These standard wireless communication technologies have notable advantages over wired communication, and even other wireless technologies to include infrared […]
Wi-Fi 6E Standard and 6 GHz Wi-Fi Band: Pros and Cons
The Wi-Fi 6E standard is a newer generation Wi-Fi technology launched in 2019 that is set to replace the earlier Wi-Fi 6 and Wi-Fi 5 standards. It adds support for using the 6 GHz frequency of the electromagnetic spectrum. The Wi-Fi Alliance, a nonprofit organization that oversees the implementation and further development of Wi-Fi technology, […]
2.4 GHz vs 5 GHz Wi-Fi: What is the Difference?
Modern Wi-Fi routers or so-called dual-band routers provide users an option to select between two frequencies or bands: the 2.4 GHz band and the 5 GHz band. Note that both frequencies fall within the microwave range of the electromagnetic spectrum. But what is the difference between the two? Which one to use? When to use […]
