- Each type of access has a unique set of strengths and limitations
inherent in the various technologies.
- DSL
- CABLE
- SATELLITE
- ColusaNET Wireless Broadband

- DSL
With DSL, both phone and Internet signals are combined and sent
over the same pair of wires.
Bandwidth (speed) is severely limited, range is typically less
than a mile. DSL was the first true broadband service but is late 1990’s
technology. Prior to DSL there
was only ISDN which was very expensive.

- 2.CABLE
- Internet access over CABLE is a
shared model based on cable “segments”.
- Multiple neighborhoods can
share the same cable segment. It
is largely the same as early Ethernet networks where coaxial cable was
“daisy-chained” from one device to the next. While easier to set up, one
break in the cable results in a loss of service for everyone on the
segment.

- 3.Satellite
- Satellites are great for some things, such as one-way delivery of TV
signals, but they’re not the best choice for the Internet if you have
local, terrestrial service available.
This is the result of the enormous distances involved; the round
trip to the satellite and back is over 70,000km. Even at the speed of light, this takes
over a half second, and is very noticeable.
- Latency from terrestrial wireless service is generally under 10
milliseconds. This makes an
enormous difference in your Internet speed and performance.

- ColusaNET Wireless Broadband is unique to this area. For over 12 years ColusaNET has been
the only source of state-of-the-art Internet connectivity
solutions. Speeds exceed DSL and
cable combined! From residential
service all the way to dedicated T-1, ColusaNET is unsurpassed in
network engineering, performance and diagnostics.
- Our newest systems are capable of up to 14 megabits split between upload
and download in any desired ratio based on service level.

- Your Internet performance is largely controlled, or limited, by not only
your choice of network components, but also your computer itself.
- The fastest Internet speeds can only be realized by understanding WHAT
NOT TO DO!
|
|
10
|
- The least troublesome and fastest possible network has only one
computer!! That is, nothing but
the terminal itself.
|
|
11
|
- If you have a router on your home or office network, YOU HAVE TOO MANY
ROUTERS!
|
|
12
|
- Due to the volume of routers on store shelves, everyone thinks they need
a router, if not several routers!
- There is no need for even a single router in any home or office
network. Every router adds more
delay, and nobody needs a router.
|
|
13
|
- Sometimes we see customers who have 3 or 4 routers plugged into each
other!!
- Having even ONE ROUTER on your home network will slow things down
unnecessarily.
|
|
14
|
- To connect several computers and/or printers together, GET A SWITCH, NOT
A ROUTER. (They’re cheaper too!)
- While they may both look nearly identical, there is a big difference;
they are NOT THE SAME THING!!!
|

16
|
- A FIREWALL stands between you and the Internet.
- Firewalls are based on rules; they block any incoming traffic not
specifically requested by the users it protects.
|
|
17
|
- Put another way, a firewall blocks all traffic from the PUBLIC SIDE of
the firewall *UNLESS* the connection was initiated from the end user on
the SAFE SIDE of the firewall.
|
|
18
|
- A ROUTER is not a switch
- A FIREWALL is not a router
- A SWITCH is neither a firewall nor a router
|
|
19
|
- If you don’t have specific knowledge about routing, you have no reason
to ever buy a router.
- To connect the devices on your home or office network, you want a
SWITCH, NOT A ROUTER.
|
|
20
|
- Don’t waste the extra money to add delay and additional failure points
to your network when a simple and less expensive Ethernet Switch is all
you SHOULD be using.
