In RV parks with Wi-Fi service, a wireless signal is
transmitted from elevated antennas that cover broad
outdoor areas. These antenna will transmit ‘useable’
signal from a few hundred feet to more than ½ mile.
While there are many variable that ultimately determine
the usability of any Wi-Fi service, your wireless
adapter is a significant factor in your ability to
use the service at any given time.
If you ever wondered why your built-in wireless works
great a Starbucks, Flying J’s etc., it is because the
access point is probably relatively close to you and
there are usually few (if any) objects that interfere
with your ability to send/receive wireless signals. In
RV parks, many environmental factors can effect your
ability to receive and send signal to an access point.
Some of the factors that contribute to signal strength
and quality are:
- Distance from the nearest antenna
- Trees blocking clear line sight between your
RV and the antenna
- Other nearby RV’s blocking clear line sight
between your RV and the antenna
- A personal Wi-Fi network set up in a
neighbouring RV
- Aluminium or other metallic window shades
blinds will reflect a signal away
- Materials used in manufacturing RV`s such as
metal trim, electrical & plumbing lines
- Window tint with metallic reflective coatings
Following is a description of the four most common
types of wireless adapters used by consumers in various
Wi-Fi environments. While this explanation is not
intended to portray the usability of each of the various
types in ALL environments, it does address some of the
benefits and limitations of each.
Wireless Card: The wireless card that comes
built-in most of today’s laptops are great for home
environments, small offices and other indoor `hotspots`
and were designed for mobility and low power
consumption. These two design elements sacrifice output
power and therefore limit access distance from an access
point. In addition, many built-in wireless cards are
located on the underside of the laptop computer, further
reducing signal reception capabilities. Lastly, many
laptop manufacturers use the same small set of vendors
for laptop components (including wireless cards) in
their Pcs. Many times this means an $500 laptop will
have the same built-ii Wi-Fi capability as a $3000
model.
PCMIA Cards: Also known as PC Cards,
they can provide enhanced signal strength and stabilize
connection speeds if you are having trouble using your
built-in wireless in an RV park environment. PC Cards
have power outputs that range from 30mW to 200mW. Some
even have built-in connectors to attach an external
antenna, enhancing signal even further. One drawback to
PC Cards is their location in reference to `signal`.
Most PC Cards have an Omni-directional antenna built-in
to the part of the card that hangs out of your PC.
Placing your computer on a desk or table effectively
blocks the lower half of the card’s built-in antenna.
Moving your PC a few inches may increase your signal
substantially.
USB Adapter: USB Adapters are probably the
single best option for using Wi-Fi in an RV park. They
combine good output power with the ability to place
theme where the signal is strongest, without having to
move your PC around. Typically, placing a USB Adapter in
a window that has visibility to the nearest Wi-Fi
antenna will provide optimum results.
Wi-Fi Antenna: Finally there is an
solution for Rvers that are at extreme distances from
the nearest Wi-Fi antenna or have lots of trees blocking
line of sight, or just want a wireless solution that is
going to work just about anywhere. This is an outdoor
radio antenna all built into a single enclosure you can
mount on the side or roof of your RV. Run a single piece
of outdoor rated CAT5 cable from the radio antenna to
your PC and plug into your Ethernet port via the
included DC injector. These units cost between $150 and
$250 but, you will probably never have to contend with a
low signal again.
The most important thing to keep in mind when
considering a new wireless adapter or antenna is
quality. When it comes to radio equipment, you really do
`get what you pay for`.
