Wi-fi or the wireless fidelity is the technology that helps exchange the information among different devices.
In the current world, where people don’t want to miss every second update, news, the technology helps them in the same. Now with the pandemic hitting badly, the majority of the population is working remotely. The technology is helping these professionals work from their desired location. These wireless networks, can be easily put up in the location you want.
So, how does Wi-fi work?
It uses the wireless technology, where the user needs to enter the wi-fi password on the device that would be used for connecting to the LAN through the router- a networking device that helps forward data packets between networks.
This technology uses the radio waves, to start the communication process. The approach is a two-way approach where both sides have to respond in the conversation path. The wireless technology uses different parts of the IEEE 802 protocol. The AP or the access point broadcasts the signal that is easily detected by devices, further making the connection to the network. For this, the devices need to have the wireless network adapters so that it could connect to the access point.
Most of the devices that use wi-fi are the computers, tablets, smartphones, laptops, drones, among others. The technology supports the connectivity for short distances.
The wi-fi transmits at the frequencies of 2.4 GHz or at around 5 GHz. All the wi-fi device are the short- range wireless devices. The devices are constructed on RF CMOS integrated circuit chips.
The high-density wi-fi is the design strategy for providing connectivity to the clients. It supports HD video streaming that would require 3 Mbps throughput.
The emergence of wi-fi 6:
It would introduce some latest technologies, and make the connectivity, speed faster. It is just required in the current times where the majority of the population uses more bandwidth. The speed is estimated to be 9.6 Gbps. The technologies that speed up the connections are OFDMA, and MU-MIMO. The OFDMA takes the wireless fidelity and then divides it into smaller frequency allocations known as the RU. The process further helps access point for communicating with different clients. It is highly flexible.
MU-MIMO is highly needed in the wireless routers. The full form of MU-MIMO is the multi-user, multiple input, multiple output. The technology shoots up the number of antennas on the router used for the transmission and also the receiving process. The MU-MIMO router is available in 2×2, 4×4 and 3×3 variations.
It would also improve the network, even if many devices are connected. It would also provide better security.
