Wi-Fi is the name of a wireless network technology that uses
radio waves to provide broadband Internet and network connections. This
Webopedia article "Did you know ...?" Explains Wi-Fi technology: how
it works and misconceptions about wireless loyalty.
Wi-Fi is the name of a wireless network technology that uses
radio waves to provide broadband Internet and network connections,
The Wi-Fi Alliance, an organization known as Wi-Fi
(registered trademark), defines explicitly Wi-Fi as the "802.11 Institute
of Electrical and Electronics Engineers (IEEE) 802.11 based on wireless local
area network (WLAN) products."
Initially, Wi-Fi was used instead of the 802.11b 2.4 GHz
standard only, but the Wi-Fi Alliance extended the general use of the term
Wi-Fi to include any WLAN network or product based on the 802.11 standards. ,
including 802.11b, 802.11a, dual-band, etc., to end the confusion about
wireless LAN interoperability.
What about Wi-Fi -Some ISPs charge additional fees for
Wi-Fi-enabled modems. But if you already have a router, you don't even need
this feature, and you can usually call your ISP and turn it off. This will save
a few dollars a month.
If you do not have a router, you may want to purchase
one. If you ask, the router is the small box that distributes your Wi-Fi signal
throughout your home, so your connection doesn't fall when you play Alto's
Adventure in the bathroom.
If you want a super stylish router, you can pay over $
100. But you can get more basic models between $ 20 and $ 60.
How Does
Wi-Fi Technology Work –
Wi-Fi works without a physical wired connection between the
transmitter and the receiver using radio frequency (RF) technology, the rate of
the electromagnetic spectrum associated with radio wave propagation. When an RF
current is supplied to an antenna, an electromagnetic field is created, capable
of propagating in space.
The cornerstone of any wireless network is an access point
(AP). The main task of an access point is to transmit a wireless signal that
computers can detect and "tune in." To connect to an access point and
join a wireless network, computers and devices must have wireless network
adapters.
Wi-Fi is compatible with many applications and devices,
including video game consoles, home networks, PDAs, mobile phones, major
operating systems, and other types of consumer electronics.
All products tested
and approved as "Wi-Fi Certified" by the Wi-Fi Alliance are certified
as interoperable from each other, even if they come from different
manufacturers. For example, a user with a Wi-Fi Certified product can use any
brand of an access point with any other brand of client hardware that is also
"Wi-Fi Certified." Products that pass this certification must bear an
identification seal on their packaging, indicating "Wi-Fi
certification" and indicating the radio frequency band used (2.5 GHz for
802.11b, 802.11g or 802.11n and 5 GHz for 802.11 a).
What is
Wireless Fidelity –
A common mistake is that the term Wi-Fi is short for
"wireless loyalty." This is not the case. Wi-Fi is simply a
registered term meaning IEEE 802.11x. The misconception that the brand
"Wi-Fi" is short for "wireless loyalty" has been extended
to the point that even industry leaders have included the term wireless loyalty
in a press release. You'll also find references to Wi-Fi synonymous with
wireless commitment in several well-known and respected technology-focused
publications and websites. The truth is that Wi-Fi isn't, and never has been.
The current confusion seems to stem from a brief period in
the early days of the Wi-Fi Alliance when an unfortunate slogan was added that
said, "The standard for wireless loyalty." It was not part of the
original name and was not created by Interbrand, but was added as a late occurrence
to help users understand the somewhat absurd new word Wi-Fi.
How much is high-speed
internet –
Technically, broadband Internet is a connection of 25
Mbps or more. It is suitable for one person, but if many people in your home
are watching HD programs at the same time, you should double triple or even
quadruple.
That said, don't pay more for the speed you don't
need. You don't have to pay for any of these super-fast gigabit plans if all
you do is browse Facebook. But if you have nine children and everyone wants to
see Hulu at the same time, maybe a gigabit sounds good.
