High Speed Satellite Internet

The latest addition to the list of newer and faster Internet accessing techniques is satellite Internet. Satellite Internet is the technology to connect to the World Wide Web though a satellite orbiting the earth. The data signals are exchanged between the host computer, ISP source and satellite.

Satellite Internet services are primarily of two types: one way and two way. In one-way satellite service, information can be downloaded via the satellite at a very high speed, but uploading is done via a regular modem. Two-way satellite Internet service supports both downloading as well as uploading of information. As uploading information through satellites may take slightly longer, it is advisable not to use this technology for applications which require fast, synchronous data transfer.

Using this service requires the installation of a dish at the user's location. Though expensive, this technology is extensively used in areas where terrestrial access to Internet is not viable, especially in sea vessels. The prime advantages of satellite Internet include: it can be used almost anywhere, it is fast, it offers 2-way connection speeds and unlimited access, and it is available in various packages to suit the user's needs.

Satellite Internet is also highly reliable. There are few incidences of a connection drop down while processing critical transactions via the net. Although a satellite connection facilitates fast Internet access, it is comparatively slower than other broadband technologies due to the long distance which the data has to travel. Its speed cannot be enhanced beyond a limit, while other services like DSL or Cable can attain much higher speeds.

However, without any wires or cables required, this technology is a sought-after option for far-off locations or sea vessels, as its reach is global. Various countries offer different methodologies to use this technology, depending upon the location of the satellite. Extremely reliable and safe, with newer and better improvisations in the pipeline, this technology is constantly improving.

Evaluating Bandwidth Choices-Fractional DS3 vs DS3

Looking for bandwidth? That can be a daunting and frustrating task even in the best of situations. There's lots to consider in order to make the right decision for your needs. Below you'll find some help when evaluating Fractional DS3 vs DS3. Factors covered include Technology, Speed, Description, Application, Pros, Cons, and Cost.

~~~~~~~~~

Technology: Fractional DS3

Speed: 3 Mbps - 44.736 Mbps

Description: A fraction of a full DS-3, which is comprised of 28 T-1s or 672 channels.

Application: Provides access from a location into the Internet for a large business or ISP (Internet Service Provider).

Pros: Provides very high speed access directly into the carrier's backbone. Bandwidth guaranteed by SLA (Service Level Agreement). Very reliable.

Cons: Setup and monthly costs can be prohibitive.

Costs: A Fractional DS3 will likely start at around $2,000 for a stable, reliable system (e.g. from a Tier 1 provider)....not including the local loop. A required router is additional unless provided as a "freebie" incentive by the vendor. Price climbs as distance from the providers Central Office (CO) increases. However....the pricing for these connections can vary widely depending on the carrier, location of service and the application for which the connection is being used. For example...Tier 1 providers will probably cost more than local/regional Tier 2 and Tier 3 providers but are much more stable and reliable. A Tier 1 provider should be the provider of choice for any business serious about the quality of their network. Also, expect to pay more if you are in a rural area or need integrated (voice and data combined) DS3 service.

Technology: DS3

Speed: 44.736 Mbps

Description: dedicated connection made up of the equivalent of 28 T-1s.

Application: Provides access from a location into the Internet for a large business or ISP (Internet Service Provider).

Pros: Circuit runs directly into the carrier's backbone. Bandwidth guaranteed by SLA (Service Level Agreement). Very reliable.

Cons: Setup and monthly costs can be prohibitive.

Costs: A full DS3 obviously will cost more than a Fractional DS3. Expect cost to start at around a $3-5,000 for a stable, reliable system (e.g. from a Tier 1 provider).....not including the local loop. A required router is additional unless provided as a "freebie" incentive by the vendor. Price climbs as distance from the providers Central Office (CO) increases. However....the pricing for these connections varies widely depending on the carrier, location of service and the application for which the connection is being used. For example...Tier 1 providers may cost more than local/regional Tier2 and Tier 3 providers but are much more stable and reliable. A Tier 1 provider should be the provider of choice for any business serious about the quality of their network. Also, expect to pay more if you are in a rural area or need integrated (voice and data combined) or bonded (multiple DS3s bound in 1 network....option vs full OC3) DS3 service.

~~~~~~~~~~

Technology: E3 (Europe)

Speed: 34.368 Mbps

Description: European equivalent of T-3. Made up of the equivalent of 28 T-1s.

Application: Provides access from a location into the Internet for a large business or ISP (Internet Service Provider).

Pros: Circuit runs directly into the carrier's backbone. Bandwidth guaranteed by SLA (Service Level Agreement). Very reliable.

Cons: Setup and monthly costs can be prohibitive.

Costs: A full E3 usually costs more than it's North American counterpart. Expect cost to start at around a $6-8,000 for a stable, reliable 45 Mbps system (e.g. from an equivalent Tier 1 provider). A required router is additional unless provided as a "freebie" incentive by the vendor (not common in Europe). Local loops range from $1,000 - $3,000/month. Price climbs as distance from the providers Central Office (CO) increases. However....just as with the North American version the pricing for these connections varies widely depending on the carrier, location of service and the application for which the connection is being used.
