What Are The Different Types Of Bandwidth BackBone Connections That Typical WISP's Use?

Here are some of the typical BackBone connections that WISP's [WISP - Wireless Internet Service Provider] use:

* SDSL (Symmetrical Digital Subscriber Line):

Speed: 128Kbps up to 1.1 Mbps

Pros:
- It can go about the same speed as a T-1 at a fraction of the cost.
- In many cases it can be installed very fast
- Easy Installation

Cons:
- Ping times are not as good as many T-1's
- Many providers do not allow resale of these lines, so you have to be careful and check the TOS
- Downtime maybe greater then that of a dedicated line
- Speed is usually NOT guaranteed
- Not available in a lot of areas

Bottom Line: For startup WISPs who would like to provide service to a minimal amount of people or who don't have the justification for a T-1 yet at the time of service.

* Dedicated T-1:

Speed: 56 kbps to 1.5 Mbps

Pros:
- Low Latency (Good Ping times)
- Speed is guaranteed
- Dedicated line (Great Tech Support, compensation for downtime)
-- Available in almost all areas around the US

Cons:
- High Cost
- Tech Savvy setup

Bottom Line: For WISPs with a good customer base that are ready for the next step.

* Bonded T-1's (Dedicated):

Speed: 3 Mbps to 6 Mbps

Pros:
- Low Latency (Good Ping times)
- Speed is guaranteed
- Dedicated line (Great Tech Support, compensation for downtime)
- Available in almost all areas around the US

Cons:
- High Cost
- Tech Savvy setup

Bottom Line: This is for WISPs that have exceeded or are projecting exceeding the maximum capacity of a T-1 in the near future, but can not justify the cost of a T-3 yet DS3 Usually, they just add T-1's and bond them to make it fast, so the lowest speed would be around 3 Mbps, so that would make the cost double in most situations.

* Dedicated T-3:

Speed: 12 Mbps to 45 Mbps

Pros:
- Low Latency (Good Ping times)
- Speed is guaranteed
- Dedicated line (Great Tech Support, compensation for downtime)
- Available in almost all areas around the US

Cons:
- High Cost
- Tech Savvy setup

Bottom Line: This connection is for WISPs who have many customers and are ready for a much faster connection. A T-3 is a big jump from a SDSL connection or say a T-1 or a Bonded T-1, so don't buy a T-3 until you are sure that you have enough users to pay for the connection.

* OC-X (e.g. OC3, OC12, OC48, OC192):

Speed: 53 Mbps to Infinity

Pros:
- Low Latency (Good Ping times)
- Speed is guaranteed
- Dedicated line (Great Tech Support, compensation for downtime)
- Available in almost all areas around the US

Cons:
- VERY High Cost
- Tech Savvy setup

Bottom Line: A very fast connection with a very high cost. DO NOT purchase one of these connections unless you have SUBSTANTIAL financial backing!!! These connections require very expensive routers, and a lot of technical experience just to get them to work.

NOTE: T-1's and T-3's are sometimes referred as DS-1's and DS-3's respectively.
