What is Satellite Internet service?
Satellite Internet service is broadband Internet access using
stationary satellites, satellite dishes and a receiver or
receiver/transmitter. This type of broadband Internet access is of
particular interest to people living in remote locations where cheaper
options such as ADSL and cable are unavailable.
What is two-way Satellite Internet service?
Two-way Satellite Internet service transfers data in both directions.
The satellite dish is relatively large and the receiver must receive and
transmit data. This type of satellite Internet service is relatively
expensive but is available to people in rural areas and in areas where
other broadband options are unavailable.
What is one-way Satellite Internet service?
One-way Satellite Internet service uses a standard modem and a
dial-up connection to upload content. The satellite dish is used only to
receive data. This method is a cheaper option and is comparable in price
to cable or ADSL.
How fast are satellite Internet services?
Speeds for two-way satellite service can be 600K and higher for
download and 128K for the upload. Cable and DSL broadband technologies
therefore have higher download speeds, but satellite systems are about
10 times faster than a normal modem.
What are the disadvantages of satellite Internet
service?
The biggest disadvantage to satellite Internet service is the
relatively high price and the reliability. Equipment, including a
two-foot by three-foot dish can cost around $600. Down-time can be
expected when there is poor weather. Many satellite providers offer a
dial-up backup service when the system is unavailable.
What are the advantages of satellite Internet
service?
The biggest up-side to this technology is that it is available just
about everywhere.
What are asynchronous and synchronous satellite
systems?
Asynchronous service means that there are different speeds for
upstream and downstream traffic. Synchronous satellite services on the
other hand, have the same speed for upstream as for downstream.
Synchronous systems are better suited to services that are heavily
impacted by delays, like video and audio streaming.
