1. Dialup
How it works
Your computer's modem dials a phone number, it connects to a computer
at your Internet Service Provider (ISP) and data is exchanged over the
connection.
How fast is it?
Not very. Theoretically, a 56k modem can download data at a rate of 53.3
kilobytes per second (KBPS) and upload at 28 KBPS but this is far from
the norm. Often, data transfer rates hover around 30-50 KBPS upload and
10-20 KBPS download.
How much does it cost?
Varies widely. Some services offer free dialup access if the customer
uses fewer than a certain number of hours each month (usually 10). Typically,
unlimited Internet access costs approximately $15/month or more, depending
on what other services are provided by the ISP, such as web-page hosting,
additional e-mail accounts, etc.
Advantages:
- Uses technology most people already have
- Relatively inexpensive
- Available almost everywhere
Disadvantages:
- Speed is much slower than other options. Many types of content (Internet
radio, games, downloading big files) are not accessible.
- Service is sometimes unreliable -- customers often get disconnected
from their ISP.
- Ties up a phone line, and/or requires the use of a second line for
Internet

in New Hampshire. ISP’s have come and gone over the last four years.
As of Winter 2003 these are the leading ISP’s in North Country/Lakes
Region providing 56 KBPS dial up service: Worldpath.net, Localnet.com,
G4 Communications, NCIA, Earthlink, Worldsurfer, and ASPI.
2. xDSL, also known as "Digital Subscriber
Line"
How it works (from http://www.howstuffworks.com/):
xDSL is a high-speed connection that uses the same wires as a regular
telephone line. The "x" refers to the fact that there are many
different kinds of DSL, the most common being ADSL (Asymmetric DSL.) Most
homes and small business users are connected to an ADSL line, which works
by using "free space" on telephone wires to transmit data. The
regular phone line connects to a DSL modem (which can either be leased
from the DSL company or purchased from a computer store) which then connects
to the computer, usually via an Ethernet card (the plug on the back of
a computer that looks like an enlarged phone jack).
Synchronous DSL (SDSL) is the second most common type of xDSL and is
used most often by businesses. ("Synchronous" means that the
upload and download speeds are the same, and this speed is usually guaranteed
by the DSL provider, which is not the case with ADSL.) SDSL is limited
to 18,000 feet from the office of the company providing the service. SDSL
also offers static IP addresses, which means that it's possible to host
a web page, e-mail server and provide other services necessary for businesses
applications.
How fast is it? (from http://www.howstuffworks.com/):
How fast data is transmitted depends on how far you are from the central
office of the company providing the xDSL service. xDSL is a distance-sensitive
technology: As the connection's length increases, the signal quality decreases
and the connection speed goes down. The limit for ADSL service is 18,000
feet (5,460 meters), though for reasons of speed and quality, many ADSL
providers establish a lower limit. Customers closer to the central office
will see speeds much faster than those located further away. ADSL technology
can provide maximum downstream (Internet to customer) speeds of up to
8 megabits per second (MBPS) at a distance of about 6,000 feet (1,820
meters), and upstream speeds of up to 640 kilobits per second (KBPS).
In practice, the best speeds widely offered today are 1.5 MBPS downstream,
with upstream speeds varying between 64 and 640 KBPS.
SDSL offers guaranteed synchronous speeds ranging from 144K to 9 Mbps,
and because of this speed, SDSL is often used as an alternative to T1
lines (see below.) The guaranteed speeds allow business users to host
servers, helping them save money, while the scalability of the service
allows an increase or decrease in the service level as their company grows.
How much does it cost?
ADSL usually begins around $30-40/month and can go higher depending on
speed and services offered by the ISP, such as extra e-mail accounts and
web storage. SDSL starts around $69/month and increases depending on the
desired speed and extra services.
Advantages:
- Faster speed makes the Internet more "useful."
- Allows phone line and Internet to be used simultaneously -- no second
phone line required.
- Connection is always on -- allows xDSL to be used to host web sites,
with no possibility of the connection's being "dropped."
Disadvantages:
- Costs more than dialup.
- Available only within approx.18,000 cable feet (and sometimes less)
of a DSL switching station.
Local Info:
Verizon and G4 Communication are expanding their service every day. They
now reach towns as far North as Littleton, Berlin and Lancaster. Verizon
offers residential ADSL, while G4 Communications focuses on business-rate
SDSL. (See above for the differences between ADSL and SDSL.)
3. Cable modem
How it works (from http://www.howstuffworks.com/):
Cable modems work by using "extra space" on the coaxial cable
used to bring cable television into a home. The cable line may then be
used by either an external or internal cable modem, plugged into a computer.
How fast is it? (from http://www.howstuffworks.com/):
Cable speeds vary greatly due to the number of people using the system
at once. A single channel is theoretically capable of 38 megabits per
second, but cable companies "cap" each connection so no one
person takes all of the bandwidth. Also, when multiple people are splitting
the remaining bandwidth, each person's individual share drops considerably.
As a user, you can observe when the speed of your connection is sluggish
and try to avoid that particular time of day. Often, just by changing
the time you are online, you can gain substantial improvement in speed.
Normally, cable connections are faster than DSL connections.
How much does it cost?:
Cable usually costs slightly more than DSL, around $40-$60 per month
Advantages:
- Same as DSL -- always on, keeps phone line free, fast speed, no drops.
- Can go anywhere cable TV wiring goes, no need to be near a switching
station.
- Download speeds are generally higher than DSL.
Disadvantages:
- Speed is highly variable depending on number of users.
- Cannot go where cable wires have not been run.
- Upload speeds are slower than DSL, making selected applications (sending
files via the Internet, Internet gaming, etc…) run slower.
Local Info:
Adelphia PowerLink and MetroCast Cable are the largest cable Internet
providers in New Hampshire. Call your local cable office to see if you
are eligible for the service.
4. ISDN- "Integrated Services Digital
Network"
How it works (from http://www.faqs.org/):
ISDN is a telephone company technology that provides Internet service,
typically in increments of 64 kilobytes/second channels. ISDN has been
around for many years, but its popularity only recently began to increase
due to the limitations of dialup service and the rise of Internet usage.
ISDN requires the phone company to install services within their phone
switches to support this digitally switched connection service.
How fast is it?
ISDN delivers faster Internet access than traditional analog dial-up access.
When the two 64 KBPS ISDN B channels are bonded, up to 128 KBPS can be
provided. More channels can be bonded to reach 256 KBPS and 384 KBPS,
at a greater cost.
Cost:
For speeds of 128k, residential service costs $70/month, and business
service costs $130/month. As the number of bonded channels increases,
the price also increases dramatically. Additionally, an ISDN modem is
required, which costs approximately $150 - $200.
Advantages:
- Brings Internet access to areas without DSL, Cable, etc…
- Service is expandable up to 384 kilobytes/second depending on need
Disadvantages:
- Much slower than other high-speed technologies
- Equipment costs and monthly fees far exceed those of other high-speed
options
- Ties up a phone line and/or requires a second line for Internet usage
Local Info:
Verizon and NCIA have teamed up to offer ISDN in Colebrook, Pittsburg,
Deerfield, Lancaster, Ctr. Ossipee and Greenfield to test market demand.
Must live within three-mile radius of telephone center in town.
G4 Communications offers ISDN in parts of the state not served by Verizon/NCIA.
Their service costs approximately the same as Verizon's business ISDN
service.
5. Satellite Internet
How it works (from http://www.earthlink.net/):
Satellite Internet requires the installation of a 2 to 3 foot satellite
dish with a clear view of the southern sky. Using a system of two modems,
one for uploading and one for downloading, information is exchanged with
satellites in geostationary orbits.
How fast is it?
Upload speed is about one-tenth of the download speed. Speeds vary from
300 KBPS download/30 KBPS upload (low) to 2000 KBPS download/80 KBPS upload
(high.)
How much does it cost?
Satellite service is usually around $50-$80 a month, but the equipment
can run as high as $500-$600, with the installation adding another $200-$300.
However, this cost can often be reduced through company promotions.
Advantages:
- Brings high-speed access to areas outside the reach of DSL and cable
- No need for phone lines to have Internet access
Disadvantages
- Equipment is very expensive compared to other options
- Heavy rain and snow can disrupt Internet service, and will not work
if view of the southern sky is blocked
- Slow upload speeds can make certain applications (sending files via
the Internet, Internet gaming, etc…) run slower than with other
high-speed technologies
Local info:
StarBand satellite Internet is provided by local businesses in Colebrook
(Lin-Jo Creations,) Lancaster (Germain's Satellite,) Meredith (Lakes Region
Communications,) and several other locations around the state. For the
location nearest you, visit http://www.starband.com/
All major satellite providers -- including DirecWay,
Earthlink etc...
-- can install the service at your residence, but purchasing from a local
provider often allows more flexibility in terms of service.
6. Wireless Internet:
How it Works:
Wireless Internet providers transmit information via high-frequency radio
signals between their tower and a special receiver, which then connects
to your computer. In order for this technology to work, there must be
a direct line-of-sight from somewhere on your property (where the receiver
will be installed) to the radio tower from which the company broadcasts
its signal.
How Fast is It?:
Varies depending on price. The lowest cost residential option is synchronous
(identical upload and download speed) 128 kilobytes/second service, and
the highest cost option is 768 kilobytes/second download and 1 megabyte/second
upload service for businesses.
Cost:
Monthly service varies from $29.95/month to $500/month depending on the
company offering the service, speed desired and physical location. Installation
and equipment costs vary from no cost to $250, depending on the length
of the service contract.
Advantages:
- No need to rely on phone company infrastructure
- Signal receiver is very low-profile, unlike satellite dish
Disadvantages:
- Service area is limited to line-of-sight, so some homes/businesses
may not be eligible even within the theoretical service area
- Equipment/installation costs are high
- 2.5 gHz devices (such as cordless phones) may disrupt signal
Local Info:
Wireless is available through NCIA in Berlin, Littleton, North Conway
and coming soon to Lancaster. FirstBridge Internet serves North Conway
and Glen. SegNet serves Conway, Claremont, Newport, Enfield, Hanover,
Lebanon, and West Lebanon. USAExpress serves Charlestown, with Claremont
and Walpole to be served soon.
7. T1 Lines:
What is it? (from http://www.howstuffworks.com/):
A T1 line is a fiber optic line into your office (a T1 line might also
come in on copper wires).
How Fast is It? (from http://www.howstuffworks.com/):
A T1 line can carry 24 digitized voice channels, or it can carry data
at a rate of 1.544 megabits per second, roughly 60 times more data than
a normal residential modem. It is also extremely reliable -- much more
reliable than an analog modem.
Cost (from http://www.howstuffworks.com/):
A T1 line can cost between $500 and $1,500 per month depending on who
provides it and where it goes. The other end of the T1 line needs to be
connected to and ISP and the total cost is a combination of the fee the
phone company charges and the fee the ISP charges.
Advantages:
- Extremely fast Internet connection
- Very reliable connection
- Can be shared among many users to maximize its usefulness
Disadvantages:
- Far too expensive for regular consumers to afford
- Complicated setup and maintenance often requires having a network
administrator or Information Technology person on staff to keep the
network running
- Unless fiber-optic cable already comes into your area, installation
might be delayed until the phone company can physically run the wiring
into your building
Local Info:
Many local ISPs can offer T1 service. It pays to ask local businesses
which ISP they recommend and get prices from several companies before
committing to a service.
