Optimizing your WiFi Connection with
the right Antenna. |
|
Nowdays,
More individuals, businesses and local
governments are enjoying wireless
internet access thanks to |
|
proliferating
Wi-Fi hotspots, home, office, and public
wireless networks. However, Wi-Fi users
are rarely |
|
completely
satisfied with the signal strength,
speed and security offeredby the off the
shelf Wi-Fi cards, routers |
|
access
points and usb adapters. |
|
|
|
Coverage Area |
|
The
coverage pattern of most Wi-Fi gear is
omni directional (360 degrees) and
assumes a home, office or |
|
coverage
area with a symmetrical footprint and
centrally located dsl or cable internet
connection. However, no |
|
two
locations are exactly the same, varying
both in dimension and size, with a
primary internet connection in the
|
|
corner
of the structure. As a result, the
radiated Wi-Fi signal covers only part
of the area intended, spilling out
|
|
into
the street or a neighboring structure.
Compounding coverage problems further,
many locate their routers, |
|
access
points or desktop Wi-Fi cards in a
closet, against the wall or under a
desk,diminishing signal strength |
|
and
limiting bandwidth. |
|
|
|
Interference and Security |
|
The
secondary consequences of a device
located on the boundaries of a home or
office are unintended |
|
interference
with neighboring networks as well as an
increased security risk. By design, WiFi
devices must |
|
share
radio spectrum, allowing co-existence of
other devices in the same physical
space. With limited |
|
bandwidth
available, abutting WiFi devices will
decrease the performance one another.
Moreover, as ones WiFi |
|
network
radiates beyond the physical space of
their own home or office, it is at an
increased risk of |
|
piggybacking
or intrusion by unauthorized users.
|
|
|
|
Community WiFi |
|
These
networks are providing a number of
services to they communities, they
service including free or pay |
|
internet
access for citizens, authorized public
worker access to key content,
surveillance and traffic cameras and
|
|
public
access to community content. And while
these networks provide access to many
areas, they are not total |
|
coverage
solutions. In addition, as more
subscribers come on line, network
capacity must be upgraded or |
|
made
more efficient to ensure sufficient
bandwidth. Providers are offering
unequal levels of service to users
|
|
and
leaving money on the table in the way of
would be subscribers and services that
are just out of the effective |
|
range
of the network. |
