A BRIEF HISTORY OF Wi-Fi
Although the term Wi-Fi was not used until 1999, wireless Internet was created as part of an FCC ruling in 1985. AT&T was the first company to work with this technology and created it for use in cash register systems. One of the major problems with early wireless signaling was that information waves were being bounced off objects and causing unclear reception on the receiving end. In the 1990s, an Australian company solved this problem and filed a patent for the wireless technology.
It took less than 20 years from the time Wi-Fi signaling was perfected for wireless Internet and wireless networking to pervade everyday life. Computer users and smartphone users connect to wireless networks on a regular basis to access the Internet and other networked devices. Cafes, libraries, bookstores, and even fast food restaurants offer their customers free or paid Wi-Fi and many homes have adopted wireless networks to allow every member of the family to connect to the Internet from virtually anywhere within the house.
Wireless Internet, which is commonly known as Wi-Fi, requires a wireless router, which transmits signals through the air to computers and printers equipped with wireless network cards or adapters. Using Wi-Fi, computer users can connect to the Internet from practically any room in their homes and can even connect to the Internet on the go using Wi-Fi hotspots.
In order to connect to a wireless network, computers and printers must have wireless adapters. These adapters can be internal or external, and there are pros and cons to both varieties. The most commonly used external Wi – Fi adapters connect to the computer via a USB port while internal wireless adapters connect directly to the computer’s motherboard.
The Benefits of Using a USB Wi-Fi Adapter
There are many benefits of using a USB Wi-Fi adapter, the top five of which are as follows:
1) NO WIRE CONNECTION
The main benefit of using a USB Wi-Fi adapter is that it connects a computer, printer, or other device to a wireless network and the Internet without requiring the computer to be hardwired to a router or other network device. The USB Wi-Fi adapter receives signals from a wireless router or other wireless device and translates the signal on the computer, so the computer user can access the Internet any time he or she is in range of a Wi-Fi hotspot or wireless network. This allows laptop computer users to be truly mobile and means that they can access the Internet anytime they are within proximity of a free Wi-Fi hotspot or within range of a wireless network they have the right to access.
Prior to the advent of wireless networking, desktop and laptop users needed to connect to a router using an Ethernet cable. Any time a laptop user traveled, he or she would have to bring an Ethernet cable to access the Internet from the hotel, satellite office, or client’s location. The computer user was then limited by the length of the Ethernet cable and if the cable was forgotten, he or she would have to purchase a new one in order to access the Internet.
2) NO INSTALLATION OF INTERNAL HARDWARE
Internal wireless adapter cards are available for both desktop and laptop computers; however, most computer users are unfamiliar with installing hardware inside their computers and could end up damaging the wireless adapter card or the computer itself during the installation process. USB Wi-Fi adapters simply plug into a USB port on the computer, so there really is no installation required, making it easy enough for just about anyone to use.
Many laptops come with built-in wireless adapter cards, but if a user purchases one that does not have one, installing an internal adapter may not be possible because of the compact configuration of laptops. While internal wireless adapters may be an option with some laptop models, the adapter cards are usually quite expensive as they are manufactured by the laptop manufacturers and are the only ones that will fit. This means users have no choice but to purchase the manufacturer’s adapter card if they want to install a wireless card internally.
Occasionally internal components installed in computers and laptops go bad, rendering them useless. This is true of graphics cards, hard drives, motherboards, memory, and wireless cards. While a computer cannot run without a hard drive or motherboard, it can run without a wireless adapter card, which means users could use a USB Wi-Fi adapter to connect to the Internet rather than having to purchase a brand new computer or internal wireless adapter if this happens.
3) NO INSTALLATION OR CONNECTION OF WIRE OR CABLE IN ANY RECEPTION
In the past, computers had to be located very close to an Internet source, be it a telephone line or cable outlet because the computer had to be plugged into the network via an Ethernet cable. This made it impossible to have the Internet source located in the living room and the computer located in the home office without running some type of cable. Although not limited to Ethernet cables in this situation, users either had to drop a phone or cable outlet into the room containing the computer or run Ethernet cable from the active outlet to the computer.
In addition to eliminating the need for additional wiring, USB Wi-Fi adapters allow multiple devices to connect to the Internet via a wireless router without filling up all the outlets on the router. This means that users could have one or two computers connected through the router via Ethernet cable if needed along with a hard-wired networked printer and additional computers connected via USB Wi-Fi adapters.
4) IT DOESN’T REQUIRE COMPUTER UPGRADE
Computers can be quite expensive, especially if a user chooses to purchase the best computer he or she can afford so that he or she needs to upgrade less often. Those who are using laptops or computers that did not come with wireless network adapters installed do not have to spend a lot of money upgrading to a newer computer if the computer they are using still works in every other way. Purchasing an inexpensive USB Wi-Fi adapter will allow these users to connect to the Internet wirelessly without spending money unnecessarily.
Computer users whose internal wireless cards are broken or outdated can also benefit from plugging in a USB Wi-Fi adapter. Rather than spending the money to replace the broken or sluggish internal wireless adapter, users can simply disable the internal card and use the USB adapter to access the Internet. This may provide a much needed Wi-Fi boost for users whose internal cards are quite old. For example, wireless adapters that have the letters b or g after the 802.11 are slower than those that have the letter n after the number. B adapters can only support a bandwidth of 11 Mbps, while g supports up to 54 Mbps and n supports double that at over 100 Mbps. If the internal wireless adapter is only an 802.11b adapter, users will gain quite a bit of bandwidth by purchasing a USB Wi-Fi adapter that supports 802.11b connectivity.
5) IT SUPPORTS MULTIPLE CONNECTIONS
One of the best things about using a USB Wi-Fi connector is that it can be shared across multiple devices quite easily. Because it is an external device that plugs into a USB port, it can easily be unmounted and unplugged when it is needed on another computer. Since all computers come with several USB ports, the USB Wi-Fi adapter can be used on virtually any computer. Windows-based computers as well as Macs support the USB technology, and as long as the manufacturer has drivers for both Windows and Mac operating systems, the same USB Wi-Fi adapter can be used on both types of computers. This makes it easy for households or offices that have both types of operating systems on their computers because they can purchase several of the same USB Wi-Fi adapters for use on all their machines, and there is no confusion about which adapter goes with which operating system.
TAKE NOTE: Although USB Wi-Fi adapters should not be left plugged into a laptop when not in use because it could break off and damage the USB port or the entire laptop, the adapters are extremely portable and easily fit into any laptop bag alongside a laptop making accessing the Internet while traveling a breeze.
A USB Wi-Fi adapter is an easy way for nearly any computer user to connect to the Internet wirelessly. Wi-Fi adapters slip easily into an available USB slot and there are USB Wi-Fi adapter models compatible with all operating systems. These portable devices increase the portability of laptops by allowing users to connect to wireless networks anywhere and eliminate the need for extra cables and internal installation. If a wireless network or Wi-Fi hotspot is already in place, users simply need to plug the Wi-Fi adapter into an available USB port, start up the computer, and install the necessary drivers; within minutes, they can be surfing the Web, also support decoder i mention i above.if you want to get or buy it you can send your request to [email protected] or whatsapp: +2348036143281, or skype: @ayokunmi8.
