WiFi, is a
technology that lets users reliably and securely send and receive
wireless data with nothing more than a WiFi enabled laptop or PDA and a
"hotspot" or network access point through which to connect. It is often
referred to as 802.11b or 802.11g, but it's all WiFi. Connection to the
Internet is not a cable, but a radio signal. Most laptop computers can
communicate only up to about 300 feet from network access point due to
the low power of their built in transmitters, which are much weaker than
cellular telephones. The low power is sufficient for indoor networks in
homes, offices, and coffee shops; but optimal communication at high
speed outdoors usually requires that the user use an external high-power
wireless device.
Typically, the user purchases time on a given
WiFi network with their credit card and uses the network simply by
visiting a host location and logging in. Many networks are
interconnected via 'roaming' arrangements that allow users to use their
WiFi connection at many places.
Maritime Communications has
extensive experience in designing, installing and operating both indoor
and outdoor networks in marinas and harbors, hotels, public areas, and
RV Parks.
