via satellite. It can be used to communicate any of the following:<br>
– Data<br>
– Voice (VoIP)<br>
– Video<br>
– Audio<br>
• VSAT Equipment consists of
an Outdoor Unit (ODU) and<br>
an Indoor Unit (IDU) and connecting cables<br>

<strong>Equipment</strong> <br>
• Outdoor Unit (ODU)<br>
– 1.2m parabolic Antenna<br>
– 2 watt Radio<br>
Frequency (RF) Unit<br>
• Indoor Unit (IDU) HughesNet Modem <br>
• Data: HN7000 – Length/Depth 27cm, Height 22cm and
Width 4cm<br>
• Voice: DW6040 –Voice Appliance (VAP). Has 4 voice
ports and comes as an additional module

  &lt;strong&gt;[u]KU Band Vs C-Band[/u]&lt;/strong&gt; &lt;br&gt;
    • Softnet operates in Ku-Band frequency.&lt;br&gt;
    • Previously, C-Band services were more popular than Ku-band due 
    to susceptibility of Ku-Band to weather conditions   such as 
    rain and fog.&lt;br&gt;
    &lt;br&gt;
    &lt;strong&gt;Why Ku Band?&lt;/strong&gt;&lt;br&gt;
    • Smaller antennas are required. Less radio power is required in 
    Ku-band than C-band to provide the same signal    strength.&lt;br&gt;
    • Cheaper :Ku-band equipment is 3 times cheaper than C band.&lt;br&gt;
    • Aesthetically better : A typical Ku-band antenna is 1.2m or 1.8m 
    and a typical C-band antenna is 1.8 or 2.4m&lt;br&gt;
    • Softnet’s availability is 99.7% with ACM and AIS.&lt;br&gt;
       FACT!&lt;br&gt;
       Ku-band terminals are in wider use worldwide than C-band 
    The majority of users accept a 0.4% difference in    availability 
    upon consideration of the initial capital investment required.
