Proper antenna configuration is a critical
factor in maximizing radio range And remember folks you do not always want your signal
to go beyond |
The location and configuration of all antennas should be carefully calculated to maximize coverage where it is necessary and minimize it where it is not wanted.
I know this might seem difficult to do but it's not as difficult as it sounds just try and move the wireless router or antenna to a different location - higher is always better when arranging wireless computers
Wireless Distances Can Be Tricky
| Antennas are
important when
arranging wireless home computers, although there are
usually ways to extend distance when using signal boosters and
multiple wireless routers or access points. Wi-Fi networking can work through most walls and other building structures, but the range is much better in open spaces. |
|
- The range of wireless adapters outdoors can be up to 1500 feet (457 meters)
- Indoors at up to 300 feet (91 meters)
These Ranges Are Under "Ideal Circumstances Without Interference"

Quick Tip:
When arranging wireless computers.
The indoor range is the most sensitive and really depends on the
structural elements of your |
Which Will Have The Best Range
-
Range of a wireless system is based more on the frequency. Then
the band that it operates in vs. the standard that it uses. What?
Read on...
802.11,g based equipment operates in the lower-frequency 2.4GHz frequency band, which suffers from less signal reduction when passing through the walls and ceilings of your home.
Range advantages will tend to be neutralized if your wireless LAN is set up in an "open field" environment that has no obstructions between the Access Points and clients.
Interference With Home Wireless Devices
Large amounts of metals in the walls can be a problem for example
heating-air conditioning-metal lath, especially older homes.
Wireless networks broadcast on the same 2.4Ghz frequency as cordless
phones
and
microwave ovens.
These devices are not supposed to interfere with each other, occasionally they might, so try and keep your computers away from the deices, micro wave ovens, cordless phones. this is especially true for base stations when arranging wireless computers.
The 802.11a equipment , and especially the dual band A
and G products,
is appealing in cases where there is potential conflicts,
specifically, if dependent on
2.4GHz cordless phones, and most of the cordless
phones use this range.
Overcome The Obstruction When Arranging Wireless Computers
- Keep your wireless
devices away from the above appliances
Router's And PC Antenna's
There are no typical set of conditions in any environment. Every room has reflections and "dead" spots. Wireless router antenna's are affected by whatever is near...
this is especially true for any metal object located in close proximity to your wireless pc or you router. when using a external antenna, it is important to keep cable lengths of high quality and short lengths
There Are Different Types Of Antennas
- A
Yagi antenna combines high gain with a wide
beam width. It is
ideally suited for directional and mutili-point applications
such as
school campus and will focus the radio beam, from point A to
point B - typically used outdoors for access points and extension points. Most commonly used antenna.
- A Parabolic for Long range and greater distances,
they are
concave and dish shaped and usually referred to as dish
shaped, point to point directed beams for long range
communications
This provides
a bridge between two access point in a network.
- An 360 degree Omni-directional antenna tend to radiate horizontally all around it. When used for a wireless LAN these antennas are usually a four inches long and external. These antennas are the most common and can cover an average home, about 2000 squire feet.
Quick Tip: Make sure the omni-directional antenna is vertical, you can move or tilt antennas to provide some better coverage if you encounter any dead spots or move it closer to the area you want to cover.
-
High Gain Antennas will Increase the
range of your Wireless network! Attach these high gain antennas
to your
Wireless Broadband Router or Access Point, and increase both the
effective strength of the outgoing signals, and the receive
sensitivity for incoming signals.
Directional Antennas Radiates
In A
Limited Direction
It is usually flat panel or dished. It is typically used
for point-to-point transmissions - where two antennas are focused
directly at one
another - They need a direct line of sight between them.
Add On Antennas To Increase Your Range
I would suggest that you give these a try if the need arises. The increased range provided by adding an external antennas is usually worth the trouble. but ot all wireless cards will allow you to attach an antenna, but if they do, remember to purchase one from the manufacture of the card, or wireless router.

Tricks To Expand Coverage
|
Again, move the equipment around a little if possible, and remember don't
stuff
your router or pc under any desk when arranging wireless
computers.
Or near any huge metal object,
especially
microwave
ovens!
which operate
in the same 2.4GHz frequency as a wireless
home network.
