Needing Wi-Fi, devices may communicate wirelessly without using wires.
This is a WLAN protocol based on IEEE 802.11 standards. WLAN
They can transfer data and access external networks wirelessly. Combining multiple WLAN-enabled devices For the uninitiated, Wi-Fi stands.
With Wi-Fi, most current devices can connect to a network, access the Internet and share resources.
How does Wi-Fi work?
Similar like listening to the radio, but in reverse. Wi-Fi, unlike AM (Amplitude Modulation) and FM (Frequency Modulation) wavelengths, allows you to send data, such as an email or a social network post, as well as receive music over the air.
Because Wi-Fi is so quick and stable, you don’t even realize it when you’re trying to watch a movie or play a game.
In order for Wi-Fi to function, a radio frequency of 2.4GHz or 5GHz must be used (if you see a wireless network with the number 5 at the end). Imagine tuning your car radio to 91.0 FM and listening to your favorite music station. Those numbers are like that. Even better, no setting is required. You can watch YouTube videos on your phone or make video calls using your Wi-Fi router.
| Differences | 2.4GHz | 5GHz |
| Channels | a total of 14 channels | 25 distinct channels |
| Interference | Additional commotion | Less interference |
| Maximum speed | Less connection speed | Speed up the connection |
| Network range | Higher range | Lower range |
| Standard | IEEE 802.11b, 802.11g, 802.11n (B, G, and N) |
IEEE 802.11a, 802.11n, 802.11ac (A, N, AC) |
Wi-Fi networks can coexist on the same frequency, which means that if you try to connect to your device, you may see networks from your neighbor’s.
Your Wi-Fi network’s speed may fluctuate. Multiple Wi-Fi networks sharing the same radio bands.
Wi-Fi in your home may be better in some areas. It all depends on your home router. A router’s signal range is like a light bulb’s.
You can considerably increase the range of your signal by placing the router in the proper location. Place it in the middle of the area you want to cover and make sure there aren’t any obstructions in the way for it to have the greatest possible range.
Wi-Fi repeaters, PLC (Power Line Communication), and Mesh systems are all options if this isn’t adequate for your network coverage.
Wireless networks: benefits and drawbacks
The simplicity with which information can be shared is one of the key advantages.
Use of the Internet to connect to numerous services is the most important benefit of Wi-Fi. In addition to high-speed internet access and Bluetooth connectivity, these services also provide VoIP.
Advantages
- Wireless technology does not necessitate the usage of cords, allowing users to communicate while on the go.
- Allows customers to be productive even while they are away from their offices due to its high level of adaptability.
- Wireless networks are cost-effective because they are easy to install and inexpensive.
Additional benefits include the ability for businesses to launch new products and services into the market. Wi-Fi services have been provided in many train stations, cafes, airport lounges, and hotels, allowing you to connect your devices while on the road.
Disadvantages
- Network security: Unauthorized users have an easier time breaking into Wi-Fi networks. Avoid using these connections in public locations as much as possible.
- Transmitting data at speeds of 1 to 54 Mbps is the norm for most wireless networks, making it less efficient than using a cable connection (100 Mbps to several Gbps).
- Some buildings may have “black areas” where the signal is poor or non-existent.
