WHAT IS SATELITE INTERNET
2

• Satellite internet offers high-speed data service
  from a geostationary satellite located at a
  distance of 22,300 miles above the equator of the
  earth. This service enables the users to transmit
  and receive data from a dish via a location on
  Earth called the Network Operations Center (NOC).
  The NOC will be connected to the internet and all
  communications from the satellite dish at the
  user side to the geostationary satellite will
  flow through them, before reaching the internet.

• From the standpoint of satellite internet users,
  the transfer of data through the satellite is not
  much different from that used by a land based
  internet provider. The important point to keep in
  mind is that once the technician configures the
  system and its connections, the satellite
  internet service acts almost the same as any
  other type of internet service. Satellite
  internet service is the only high-speed internet
  option available for millions of Americans living
  in rural parts of the country.

• Improvements in satellite internet technology and
  the rapid increase in competition have led to the
  introduction of more reliable and better
  satellite internet services. Many of the internet
  service providers in the country offer satellite
  internet packages that provide speeds comparable
  to those offered via DSL and cable.

In addition, innovations and technologies in
satellite internet services have resulted in a
steep decline in the cost of data accessible per
GB. The below graph will better illustrate the
changes in the cost per GB over the years.
Experts in telecommunications say that this will
rapidly decrease in the coming years also.

• Working of Satellite Internet
• As said above, satellite internet service makes
  use of geostationary satellites rather than cable
  or telephone lines to transmit and receive data.
  These satellites will remain fixed relative to a
  location on the Earth as the revolution velocity
  of the satellite matches with the speed of
  revolution of the Earth. These satellites offer
  two-way data communication between the small dish
  antennas mounted on the home of the user and the
  NOC hub of the internet service provider.

• When the user accesses a website, a request is
  sent from the users computer to the satellite
  via the dish. The satellite upon receiving
  retransmits this request to the service hub (NOC)
  of the provider, which is connected to the
  internet. The details of the website requested by
  the user will be beamed back to the satellite by
  the NOC from where the data will be sent to the
  dish antenna of the user. The modem connected to
  the dish will translate the data and the website
  will load on the users computer. The internet
  signal will have to travel enormous distances
  back and forth but will take only a few seconds
  for the complete process to happen.

10

• Users will be able to connect all the
  internet-enabled devices in their home to the
  World Wide Web by making use of satellite
  internet. In addition to having the necessary
  equipment, a clear view of the sky is also
  required to get uninterrupted satellite internet.
  This is because the dish will need a clear line
  of sight to the satellite for proper transmission
  and reception of the signal. This means that
  extreme weather may affect the service in rare
  situations.

11

• Benefits of Satellite Internet
• Satellite internet can be the fitting option for
  remote, rural, and isolated areas that do not
  have access to any other internet service
  options. None of the businesses can afford to
  remain disconnected from the internet these days
  and satellite internet offers an excellent way
  for them to access the high-speed internet at
  virtually any location. Besides, satellite
  internet offers the users with many benefits over
  other internet options like cable and DSL.

12

• Global Coverage
• One of the important benefits of satellite
  internet service is its extensive coverage of any
  location on Earth. A single geostationary
  satellite can be used to offer coverage across
  continents. This wide area coverage of the
  service makes it the best option for remote and
  underserved locations. A clearer line of sight
  view of the geostationary satellite,
  communications equipment, and a power supply is
  all that is required to establish a successful
  satellite internet connection

13

• High-Speed Access
• Speed is another important benefit of opting
  satellite internet. Most of the satellite
  internet providers operating in the country can
  offer speeds that are much faster than many of
  the terrestrial internet options available. If
  only limited internet options like dial-up and
  slow DSL are available in an area, satellite
  internet will be the best option, as it will
  offer high-speed internet access

14
Cost EffectiveStudies show that it will cost
between 10,000 and 100,000 dollars to lay a mile
of optical fiber cable in an underserved
location. Apart from the high investments, it
will take many months to finish the deployment of
the fiber completely to make the service
available to different locations. If reliable
terrestrial connectivity is not present, then
satellite internet will be the most cost
effective way to provide high-speed internet
service in an area.
15
ReliabilityAs the satellite internet only
consists of a satellite, NOC, and receiving dish,
chances of network outages will be very low. When
compared to terrestrial internet options, the
chances of outages are very limited. In case of
terrestrial internet services, network outage can
happen at any point in the infrastructure that
can hinder the connectivity. A satellite internet
service can work independently of any terrestrial
infrastructure to offer connectivity as long as
power is supplied to the equipment.
16

• Bandwidth Availability
• Telecom experts say that the geostationary orbit
  can have about one hundred and eighty parking
  spots for accommodating different satellites.
  Even though there are only limited parking spots
  for the geostationary satellites, many satellite
  service providers can offer gigabit speeds across
  the entire continent. This bandwidth will be
  available throughout the footprint of the
  satellite that is offering high-speed internet
  access at any area

17

• Easy and Quick Installation
• Installation of the service just needs a
  satellite dish, modem, and power supply and can
  be finished quickly, as there is no need to lay
  down cables or any other network infrastructure.
  After the user signs up for the satellite
  internet service, the provider can send their
  technicians who can finish the installation in
  just a matter of hours.

18

• Satellite Internet Equipment and Setup
• There are three main components of a satellite
  internet service, a geostationary satellite
  located in orbit around the Earth, a satellite
  dish mounted on the users home, and a modem to
  translate the signals from the dish to the
  computer and vice versa. When users sign up for a
  satellite internet service, they will receive a
  satellite dish and the modem. Some of the service
  providers cover the equipment cost and
  installation charges when users sign up for
  long-term contracts, while the others may charge
  an activation and installation fee separately.

• Satellite internet
• service might not be the fastest internet
  connectivity option in the world. However, it is
  capable of offering data speeds that are ten
  times faster than the normal dial up connections
  available in a region. Moreover, satellite
  internet can be a great way to offer high-speed
  internet to the rural areas of the country.
