What Is WiFi LAN?

The term WiFi has become interchangeable with any Wireless Local Area Network due to its overwhelming popularity in public places like coffee shops and airports. Private businesses like restaurants may use this technology to attract customers.

WiFi LAN is a more advanced method of wireless connection. It allows a single user to network multiple devices more easily and with better speed than the older methods.

It harnesses current technology to provide faster speeds, increased quality of service, greater security, and more robust, more flexible connections between multiple devices. In addition to being able to be used by more than one device at a time, it provides greater bandwidth not only for more devices but also for larger files transmissions as well as media streaming from one device to another throughout your home or business.  

Uses Of WiFi LAN

Connect Multiple Computers And Network Devices

It uses radio signals to wirelessly connect multiple computers and network devices at high transfer speeds without needing an actual wire for each connection, like the older LAN (Local Area Network) wiring methods. This is possible by using a WiFi router set up as the central point of contact between all wireless devices within the signal range.

Increased Portability, Affordability, And Speed

WiFi has become popular due to its portability, affordability, speed, security features, and ease of use. These features have made it accessible to home users as well as businesses. This type of network can be set up even in small dwellings with one or two rooms with devices capable of accessing them without any special hardware or configuration needed other than having the right software on each device connecting to it.

Used In Homes, Businesses, Schools, And Public Spaces

WiFi is commonly used in homes, businesses, schools, and public spaces like coffee shops or airports to allow internet access on multiple devices simultaneously without needing a LAN cable for each device to be connected. These networks are also standard in large office buildings where they can cover entire floors. The signal is extended from one router that acts as a hub through WiFi repeaters or signal boosters located throughout the building. 

This type of setup allows employees to have constant connectivity within their workspace not only with their laptop but also with smartphones and tablets as well if there is a WiFi-enabled version of those devices which most major brands now have built into them by default so they may easily connect anywhere they go seeking a signal of being tethered by cables.

Benefits Of Wifi LAN

Faster Internet Speed

Faster internet speeds are the critical advantage of WiFi wireless connections. Because it’s not tied to cables or Ethernet, there is no bottleneck created by having an adapter that can’t process all the data, which is lost when transferring large files. Users may download songs, movies, and other content at maximum speed without having to worry about how fast their connection is or what type of cable they have plugged into their computer.

No More Tethering

Access to your device from anywhere within range means you no longer have to utilize tethering on your mobile device, which consumes your phone battery life as well as incurring fees depending upon your carrier plan for mobile hotspot access with each use even if you are trying to stretch a few extra minutes because you left the office without your charger.

Expanding Of Network

Expanding your network with wireless repeaters or signal boosters is a simple setup that requires little technical experience and can accommodate most devices without additional configuration needed.

Safe From Hackers; Safe From Stealing Of Data

The use of encryption software on the router as well as each device being connected means you don’t have to worry about a user getting onto a public network, stealing an unsecured password for a social media site, or downloading something which makes them part of a botnet used by hackers to launch cyber-attacks at their whim since all communications are encrypted from one device to another so only those participating know what is going on and not casual onlookers are sitting nearby using the same hotspot access point as you who may be your movements and actions through programs like Firesheep which has become popular in recent years.

Lower Costs

Lower costs are another benefit that WiFi can offer. Most ISPs now have different tiers of bandwidth being sold, with the cost per GB also varying depending upon whether you are using cable or DSL connections as well as what area code you live in, where more widely populated areas will often see higher prices for their service offerings with less variety. In contrast, remote rural regions may have a lower selection of plans, but it’s not uncommon to find several providers offering several speeds at competitive prices.

Used On Any Device

WiFi LAN can be used on any device with wireless access, including laptops, smartphones, specific and iPads, by downloading the appropriate software needed for that particular platform since nearly all wireless-enabled devices are now built into this functionality by default without needing to purchase additional hardware.

Drawbacks Of Wifi LAN

No Great Wifi Signal When Compares With Wire Connection

The range of WiFi signals is not as great as a wired connection which means you may have difficulty accessing the signal from specific locations such as an office on another floor, your neighbor’s apartment, or even outside if it’s too far away. 

This can be overcome by using one or more wireless repeaters or boosters throughout your area to assist with extending that range into different rooms and sizes. Still, it will be necessary to place them in a location where they will receive robust connectivity and minimal interference from other electronic devices such as cordless phones, baby monitors, microwaves, and other appliances.

Not Faster From Ethernet Cables

Wireless connections are not always faster than traditional Ethernet cables depending upon your internet plan and what speed tier you subscribe to, plus how many people are currently sharing that link. There may be congestion on the network where everyone is trying to do something online at the same time, which gets resolved through establishing priorities allowing those who are uploading or downloading larger files to have uninterrupted connectivity where email, web browsing, and other lighter activities are pushed into a lower priority queue if they take too long to load or finish working.

Needs To Be Properly Secured

Any WiFi network owner must take adequate security measures for their protection as well as that of others using your connection, such as requiring each user of your wireless access point to enter a password before being able to utilize that service so strangers cannot connect without permission and firewalls should always be used on routers even if it means limiting outbound traffic from PCs attached to the unit, so only the software needed to complete a task can go online.

Overload On Wifi LAN Can Bog Down The Speed

Accessing WiFi from multiple devices simultaneously can bog down the network speed in a home setting where everyone is trying to do something, which could overwhelm that access point and slow everything down for everyone using it.


WiFi is a convenient way to wirelessly connect laptops, smartphones, and tablets with the internet anywhere you are without having to install any cables or plug in an Ethernet cable, ensuring it’s always available wherever you go.

WiFi LAN is a more advanced method of wireless connection. It allows a single user to network multiple devices more easily and with better speed than the older methods.

If your home network goes down, however, your wireless devices won’t be able to get online at all unless there is a different way to connect them, such as an ISP cable modem which is still dependent upon the stability of whichever corporation or organization that you subscribe to for those services.
