“802.11b was the first technology
of Wi-Fi wireless network communication that was  achieved mass adoption with consumers. In
the 802.11 family, there are many Institute
of Electrical and Electronics Engineers standards of 802.11b. The newer 802.11g and 802.11n Wi-Fi standards are used to made obsolete
and phased  product  of  802.11b.”

“In the  middle of 
1980s,  radio frequency is used
space around 2.4 GHz was controlled by government agencies in the
world.”

“This band (U.S. Federal Communications
initiated) is used to change and to remove regulation , previously limited to
so-called ISM equipment. The development of commercial applications was
encouraged by their basic aim.”

“Some level of technical standardization
among customers on a large scale are required by building commercial wireless
systems . That’s where the IEEE 802.11 stepped in and assigned its  working group to design a solution, which in
the end became known as Wi-Fi. The first 802.11 Wi-Fi standard, published
in 1997, had too many technical limitations to be widely useful, but 802.11 Wi-Fi
was a cause for the development of a second generation standard which known as 802.11b.”

“802.11b  helped launch the first wave
of wireless home networking. In 1999, manufacturers of broadband routers like Linksys WRT54GS began selling Wi-Fi routers alongside the
wired Ethernet models they had been producing before. Though
there was a difficult to set up and manage these older products, 802.11b demonstrate
the convenience and potential and turned Wi-Fi into a huge commercial
success.”

802.11b Performance:

“A theoretical maximum data rate of 11 Mbps is supported 802.11b connections support. Although
comparable to traditional Ethernet (10 Mbps), B performs
significantly slower than all newer Wi-Fi and Ethernet technologies.”

802.11b and Wireless
Interference:

“Transmitting in the unregulated 2.4 GHz
frequency range, 802.11b transmitters can encounter radio interference from
other wireless household products like cordless telephones, microwave ovens,
garage door openers, and baby monitors.”

 “802.11g  is
an IEEE standard Wi-Fi wireless networking technology. Like other versions
of Wi-Fi, 802.11g supports wireless
local area network communications
among computers, broadband routers, and many other consumer devices.”                                                                                                                                                            

“G was ratified in June of 2003, and  it is replaced the older 802.11b  standard, later eventually replaced
by 802.11n  and newer standards.”

How Fast Is 802.11g:

“802.11g Wi-Fi has ability to support a
maximum network bandwidth of 54 Mbps, which is higher than the 11 Mbps rating of B and  less than the 150 Mbps or greater speeds of
N.                                                                          
                                                                                            Similarly
many other kinds of networking, G is not able to achieve the maximum rating in
practice; 802.11g connections  hit an
application data transfer rate limit between 24 Mbps and 31 Mbps.”                                                                                            

Working:                                                                                                                                                          
“G
incorporated is a  radio communication
technique known as  Orthogonal Frequency Division Multiplex  that
was  introduced to Wi-Fi with 802.11a . OFDM technology enabled G and A to
get  greater network performance than B.”

“On the other hand, 802.11g chosen the same
2.4 GHz range of communication frequencies 
introduced to Wi-Fi with 802.11b.Using this frequency gave Wi-Fi
devices  greater signal range than what A
can offer. 14 possible channels that 802.11g can work on, though some are
illegal in some countries. The frequencies from channel 1-14 range between
2.412 GHz to 2.484 GHz.G was specially designed for cross compatibility.”

“What is meanings of  that devices can coordinate wireless networks
even when the wireless access point runs a different Wi-Fi version.The
newest 802.11ac Wi-Fi equipment today can support
connections from G clients.”

802.11g for Home Networking
and Travel:

“There are many number of brands and models
of computer laptops and other Wi-Fi devices were made with Wi-Fi radios
supporting G. As it combined some of the best elements of A and B, 802.11g
became the predominant Wi-Fi standard at a time when the adoption of home
networking exploded worldwide.Many home networks today still operate
using 802.11g routers. At 54 Mbps, these routers can keep up with
most high-speed home internet connections including basic video streaming and
online gaming usages.”

“They can be found inexpensively through both
retail and secondhand sales outlets. However, G networks can reach performance
limits quickly when multiple devices are connected and simultaneously active,
but this is true for any network that’s consumed by too many devices.In addition to G routers
designed for fixed installation in homes, 802.11g travel routers also gained substantial popularity with
business professionals and families who needed to share a single wired Ethernet connection among their wireless
devices.G (and some N) travel routers can still be found in retail outlets but
have become increasingly uncommon as hotel and other public internet services
shift from Ethernet to wireless hotspots.”

“802.11n is a standard (IEEE) for Wi-Fi wireless local network communications, contract in 2009.802.11n is
designed to exchange the  802.11a,  802.11b and 802.11g  Wi-Fi technologies.”

 Wireless Technologies
in 802.11n:

“802.11n uses multiple wireless
antennas in tandem for transmitting and receiving  data. The term MIMO  refers to the ability of
802.11n and like other technologies to coordinate multiple simultaneous radio
signals. MIMO is used to increase  the
range and throughput of a wireless network. An other technique employed by
802.11n that involves increasing the channel bandwidth.  Such networks 802.11a/b/g, and each .11n
device that uses a preset Wi-Fi channel on which is used for transmitting. Such
channel will use a larger frequency range , also increasing data throughput.”

802.11n Performance:

“802.11n connections that support
maximum theory based network bandwidth upto300 Mbps which primarily depends on the number of
wireless radios incorporated into devices.”
