Satellite Phones vs Cell Phones (Which One is Right for You?)
There are several factors that differentiate satellite phones
from cell phones. How they work, their utility and cost just to
name a few.
Functionality Differences
Cellular phones or cell phones use small stations or towers
known as ‘cells' from which they receive their signals and
to which they send signals. As the user moves from one
destination to the next, his call or his cellular service is
passed on from cell to the next. The mobile handset is thus in
continuous connectivity with the different cells of the network
provider and the individual can talk on the move. This is thus
known as mobile connectivity.
Satellite phones on the other hand, do not use ‘cells' or
towers. They work with satellites orbiting the Earth. These Low
Earth Orbiting or LEO satellites receive signals from the
satellite phone handsets and send signals to these handsets as
required. The satellite phones send signals to the satellite,
which passes it on to a gateway. The gateway routes the calls to
the receiver. Also, all calls made to the satellite phones are
routed via the satellites.
Differences In Area Coverage
Cellular phone companies generally provide network coverage in
densely populated areas. Since the companies have to set up
‘cells' to be able to provide coverage, they need a high
number of subscribers to justify setting up the cell. In thinly
populated areas or remote areas with difficult terrains, the
cost of providing coverage is often more than the expected
returns. Hence, while cell phones work great in densely
populated areas, they may or may not work in inaccessible
locations.
Satellite phones communicate with the LEO satellites and not
with any ‘cells' on Earth. Hence, the coverage provided by
satellite phone companies is far greater than that provided by
cellular phone companies. Since satellite companies don't have
to set up cells from destination to destination, they offer
service in a wider area and some even offer it across the globe.
Usability Differences
Cell phones have become an absolute necessity for practically
all urban residents. In fact, a large number of people are
opting to have cell phones instead of the traditional landlines.
Cell phones are perfect to use while on the move in metropolitan
cities. For marketing and sales executives, employees, CEOs,
managers, mothers, students and almost all people in different
walks of life - cell phones provide a high value service. They
are also a great option to surf the net, listen to music and
exchange photos. In short, cell phones have become the single
all-purpose media electronic instrument of the 21st century.
Satellite phones on the other hand, are perfect for use in
remote and thinly populated areas where cellular companies do
not provide network coverage. Satellite phones are also
extremely handy in situations when cellular networks go down.
Such situations generally arise in times of natural disasters
like hurricanes, earthquakes and floods when the ‘cells'
that route calls are damaged.
Satellite phones have the advantage in such conditions since
natural disasters do not affect the LEO satellites. Hence while
cellular phone networks are down, satellite phones continue to
function as normal. This has indeed saved many lives in the
recent past.
Satellite phones are also the perfect option for companies that
have research laboratories or departments in isolated areas like
Alaska, Siberia and Antartica. Adventurers who frequently travel
to densely populated tropical forests, high mountain areas and
across oceans also prefer the better coverage provided by
satellite phones.
Differences In Cost
As is to be expected, cellular phones are far cheaper to operate
and maintain than satellite phones. The cellular phone handsets
as well as the subscription plans offered by cellular service
providers are extremely affordable and cost barely a few cents
per minute.
Satellite phones on the other hand are expensive. The satellite
phone hand sets or the fixed satellite phone sets cost a pretty
penny as does the satellite phone service provided by leaders in
the industry like Iridium and Globalstar. At an average
satellite phones can cost anything from $600 to $1000 with costs
going up to $1.50 per minute for talktime.
Thus, cell phones and satellite phones are both a boon to the
world of communication and both service users in different ways
and under differing conditions.
