					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
 The trick lies in pinpointing the client's location and orienting the 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
