					 Long range Wi-Fi antennas are the driving
 force behind long range wireless networks.
  An antenna is a device that transmits and
      receives electromagnetic signals. A
  transmission antenna converts alternating
          voltage electrical signals into
     electromagnetic waves and a receiver
  antenna converts electromagnetic signals
    back to electrical signals. A long range
Wi-Fi antenna is used for providing Internet
     connectivity, or wireless connectivity,
    between two geographically separated,
   distant points. Long range antennas can
      pick up network signals from distant
 networks. Most Wi-Fi antennas have dBi
as their standard measure rather than dBd.
Dipole reference antennas work at 2.14 dBi
that corresponds to 0 dBd. Higher values of
gain indicate an antenna capable of working
    at higher levels of power, which usually
          results in greater range.

 The Wi-Fi antennas attached to the wireless routers are
omni-directional The omni-directional antennas transmit and receive
data from all the sides, i e
 the range of these antennas is 360 degrees If the router is kept
near the walls or some obstruction, the 360 degree full range will be
obstructed and you will utilize only a part of the receiver strength
Also, you can upgrade the antenna of your router to a highly
directional antenna
 The directional antennas receive signals only in a particular direction
 With the directional antennas, you can direct the signal according to
your needs This is one way of increasing the range of wireless
network
   Wi-Fi antennas encounter several problems in rural environments,
primarily landscape interference and signal reception difficulty
resulting from long-range transmission To compensate for these
factors, rural users must select an antenna designed for long-range
transmission as well as their location Directional antennas radiate
signals in a focused signal, making them ideal for areas that allow for
a direct line of sight with the receiver
 Omni-directional antennas; due to their signal pattern, are more
suited to areas with uneven terrain and varying elevation
Directional Wi-Fi antennas are most often seen in outdoor settings,
particularly when bridging between two buildings However, they can
also assist with indoor communications, especially in crowded
environments where signals may have to bounce off of many objects
before reaching their destinations
 The trick lies in pinpointing the client's location and orienting the
antenna access point's directional antenna for maximum reception,
much like aligning a satellite dish with a geosynchronous satellite
Wi-Fi antennas are available in a wide variety of mounting styles to
suit the needs of diverse projects
 From low-profile ceiling, corner, patch and surface mounts to
omni-directional and magnet mounts, the range of designs allows for
great flexibility when creating and installing Wi-Fi networks have
been producing and souring antennas and cable assemblies for over
10 years
