Wireless Speeds And Standards You Might Want to Know About
|
|
Bewildered about wireless home computer speeds on your wireless home
computer
let me explain.
Wi-Fi is the umbrella term for the standards based wireless local area
network communications protocol.
When you talk about wireless data connections, you're talking about
Wi-Fi today. |

The 802.11-G-Router
Here is a
listing of approximate indoor wireless computer
distance for 802.11g 54 Mbps - 20 meters about 65 feet
|
The 802.11-N-Router Wireless Speeds
4 Times the Range and 12 times faster then wireless,
G.
N-
MIMO (multiple input multiple output), in which a number of antennas
transmit Data.
Again
this is under ideal conditions, don't go crazy over these spec's
folks,
go
with N for
media-intensive applications (video, games, etc) what's next
wireless z? See
Arranging wireless antennas. |
You can cover a large room if you put the wireless router or access
point in the center of the room and place all of the wireless computers
around your computer
I have found that most of the router work exceptionally well under
100-ft, if you need
the greater range go out and purchase a
range expander or some
high gain antennas
With an increase in wireless speeds
802.11g which is rated at 54Mbp unless you install a 802.11b card
(11Mbps) , then the speed drops to the slowest device 802.11b, 802.11g
are compatible with 802.11b.g,n network interface (NIC) cards.

Quick Tip:
The wireless speeds gold standard is *802.11n
- the newest, fastest and most powerful (so far) 802.11 radio
technology that broadens bandwidths on the 2.4 GHz band.
Two standards work together fine 802.11b
and 802.11g,n But if I where installing a new wireless network or
adding new wireless pc's
I would use the 802.11 n for all of my
computers. |
Wireless Home Computer Speeds - No Matter How Fast We Still Want To Go
Faster
Interference doesn't kill a wireless network connection, it
just slows it down as the connection fights through the competing radio
waves.
The intermittent nature of the interference in the home or business
makes it difficult to track down the offending devices, so focus on the
cordless phones and microwave ranges which operate in the same
2.4 GHz band width.
Wireless Speed and Wired Networks
Quick Tips
Troubleshooting
cabling performance If you're experiencing connection problems- check
the following
- Look for sources of interference, such as power outlets,
fluorescent lights, power supplies, and coiled or extra-long cables.
- Make sure all cable connections are secure. Check the link light
on the network card - Nic - the devices you are connecting with each
cable.
- Make sure you have used the correct type of cables, either
straight through or crossover. Check hardware setup instructions and
configuration to verify which cable you might need.
- Be sure that you have not used a telephone cable in an Ethernet
cable port.
The Speed Chain Of
Command Goes Like This
-
Coaxial cable Uses shielding to keep the signal focused which
reduces interference
-
Twisted pair Most commonly used in wired networks - UTP Cat
5e,6a twists the pairs around each other to reduce interference
and reinforce the signal.
Here is
a
kit to make your own cables
if you buy the cable in bulk, and save money by doing
it yourself
It's Not Uncommon
In The Computer Industry

To exaggerate a little about the
wireless speed of their devices, after all is a 17-inch monitor really
17 inches.
The main reason for the wireless speeds
inflated rating is that some of it is taken by overhead, and even these
lower capacities can be limited by distance, walls and
other wireless
environmental conditions.
