What is the use of Band in Wi-Fi & Major role of Bands

 Wi-Fi is a technology that allows devices to connect wirelessly to the internet or a local network. It uses radio waves to transmit data between devices eliminating the need for physical cables.

Wi-Fi technology is based on a set of standards developed by the Institute of Electrical and Electronics Engineers (IEEE) called 802.11.These standards define the technical specifications for wireless local area networks (WLANs).

To use Wi-Fi you need a Wi-Fi-enabled device like a smartphone laptop or tablet, and a wireless router or access point.The router or access point connects to the internet or a local network using a wired connection, and then broadcasts the wireless signal to Wi-Fi-enabled devices in the area.

When a device connects to a Wi-Fi network it is assigned an IP address which allows it to communicate with other devices on the network and access the internet.Wi-Fi networks can be secured with a password or other authentication methods to prevent unauthorized access.

Wi-Fi is widely used in homes offices schools and public places like cafes airports and hotels.It has revolutionized the way we access the internet and enabled us to stay connected on the go.

In Wi-Fi the term "band" refers to the range of frequencies that are used to transmit data wirelessly.Wi-Fi operates in two primary bands 2.4GHz band and the 5GHz band.These bands are further divided into channels which are specific frequencies within the band that can be used for data transmission.

The main use of bands in Wi-Fi is to provide different options for transmitting data wirelessly.Different bands and channels have different characteristics like range speed and interference resistance which can make them more suitable for certain applications for example the 2.4GHz band has a longer range and can penetrate walls and other obstacles more easily than the 5GHz band but it is also more susceptible to interference from other wireless devices and can be slower.The 5GHz band on the other hand has a shorter range but can support higher speeds and is less prone to interference.

The major role of bands in Wi-Fi is to enable multiple devices to use wireless communication without interference.By using different bands and channels multiple devices can connect to a Wi-Fi network and transmit data simultaneously without interfering with each other.

In addition newer Wi-Fi standards like Wi-Fi 6 and Wi-Fi 6E use additional bands like the 6GHz band to provide even more options for wireless communication.These new bands offer faster speeds more capacity, and lower latency making them wellsuited for applications like streaming video online gaming and virtual reality.Use of different bands and channels in Wi-Fi allows for more flexible and efficient wireless communication enabling us to stay connected and productive in a variety of settings.For more info on Wi-Fi 6 and Wi-Fi 6E click here.

IPS & AMOLED DISPLAY || PROS & CONS || BETTER DISPLAY

  AMOLED and IPS are two different types of display technologies used in modern smartphone televisions and other electronic devices.In this article we will discuss the technical details and characteristics of each technology as well as their pros and cons. IPS (In-Plane Switching) and AMOLED (Active-Matrix Organic Light-Emitting Diode) are two different types of display technologies used in modern smartphones and other electronic devices. Here are some differences between IPS and AMOLED Display quality : AMOLED displays typically offer more vivid colors and deeper blacks than IPS displays due to their ability to turn off individual pixels to create true blacks. Power consumption : AMOLED displays are more power-efficient than IPS displays especially when displaying black or dark colors because they do not require a backlight to operate. Viewing angles : IPS displays generally offer better viewing angles than AMOLED displays which can appear washed out when viewed from an angl...

What does "nm" mean for Processor || Importance of Processor || What is 4 nm Processor

 NM (nanometer) is a term used to describe the size of the transistors that make up the processor.The smaller the size the more transistors can fit into the same area and the more powerful and energy-efficient the processor can be. For example a 7nm processor has transistors that are 7 nanometers in size whereas a 14nm processor has transistors that are 14 nanometers in size.The smaller size of the 7nm transistors allows more of them to be packed onto the processor resulting in better performance and lower power consumption compared to a processor with larger transistors. The importance of the size of transistors in a processor lies in the fact that it directly affects the performance and power efficiency of the processor.As the size of the transistors gets smaller the processor can perform more calculations per clock cycle which increases its overall speed and efficiency.Additionally smaller transistors require less power to switch on and of which reduces the power consumption and...
