Depending on what your job is, maintaining the home office may include a fast PC or laptop, a phone and long distance plan, a scanner, and a printer. Most of us make an effort to back up our actual work, but have you even considered what you’ll do if you lose your internet connection for more than a few hours?
No? Then let’s look at a few alternate ways to connect to the internet.
Wireless Internet Card
A couple of years ago I purchased a Verizon Wireless PCMIA card to use on my notebook. I intended to use it when I traveled, and I did. In 2006, when thunderstorms put our phone service out for over a day, I ended up working on the laptop instead of my PC – because it could connect wirelessly.
Next I purchased a Media Center PC that had built-in Wi-Fi. Since the notebook did, too, I could then make the laptop become a hotspot to share the internet connection with my desktop PC.
Since then, I’ve changed both my notebook and my wireless card. The new “card” is a Verizon Wireless USB stick. It plugs directly into the front of my desktop and connects the same way the laptop does.
It’s not inexpensive. The USB stick runs $69/mo standalone or $59/mo if you also have a cell phone with Verizon. Sprint lists the same USB stick for $59.99/mo.
Note that not all areas get great reception with a wireless card. Be sure that if you purchase a wireless card to use with your notebook and as a backup internet source for your desktop, make use of that 30-day return policy the carriers offer and make sure it works plugged into your PC or notebook where you actually intend to use it.
What kind of performance can be expected with a modern wireless card? The current Verizon cards run under the “EVDO rev. 1″ protocol, which provides a third generation, or 3G, network. I tested the speed of the USB stick for this article at speedtest.net and saw 1,617 kb/s (kilobits per second) download, 464 up. This compares to DSL, which is my primary connection, at 646.4 KB/s (kilobytes per second) down and 52.3 up.
So let’s convert kb/s to KB/s so we can directly compare. This amazing formula comes into play:
((1617 x 1000)/8)/1024 = 197.4 KB/s is the USB’s sticks download speed.
Bear in mind that our government says that anything over 786 kb/s is broadband! That’s about 96 KB/s. (To put this into perspective, a 500 KB/s connection downloads a megabyte every 2 seconds. That same megabyte will take over 10 seconds at our government’s minimal broadband speed.)
Anyway, this shows that my wireless card is about one-third as fast as my DSL connection.
This is probably the worst internet connection backup system. Unless you live in a place where there is literally no other choice, you wouldn’t want to use satellite internet as your primary access, much less your backup. It’s expensive, it’s slow, and it’s throttled.
I’ll explain about throttling. Imagine a bucket beneath a faucet. As the water runs, the bucket fills. This represents your downloads – files, photos, and YouTube videos. Then imagine that bucket propped up on a couple of bricks, now with a small hole drilled into the bottom of it. That hole allows some of the water to drain out, extending the time before the bucket becomes overfilled and starts “spilling over.”
All ISPs do some sort of “network shaping.” However, they do it by changing the size of the pipe itself, and the bucket is so large that most folks never have to think about. The throttling the other ISPs do is simply to limit the connection speed (max speed or “provisioned speed”) to what the user agreement specifies. I can watch a network activity graph when I’m downloading and see it peaking right at the limit that I’m paying for.
In this second page, we continue to look at using a satellite connection as a backup Internet connection. We discuss FAP, or the “fair access plan” involved, and look at download speeds. We also look at using a landline (phone connection) as a backup which may be free from your DSL provider and at connecting to the Internet through a cell phone or PDA that has its own wireless connection.

Now back to the satellite plan. The problem is that the bucket, the amount of kilobytes of data that you can download, is pretty small. Once you’ve used up your bucket within a certain time, say one 24-hour period, you can only get what comes through the leak, and that’s much, much slower. It’s a dribble.
Using HughesNet ™ as an example, their most basic plan gives the user a 200 MB bucket. The dribble is a sub-dialup speed. The refill time for the bucket is 24-hours. (What I’m calling a bucket and a drip, the satellite carriers call FAP, for “Fair Access Plan.”)
There are other problems with satellite internet. One is the amount of time it takes to send a stream of data from the earth to the satellite and down to the user. It can take a second or two to respond to a clinked link. And it’s expensive – $40 to $160 per month. You may even have to purchase the modem and dish.
Something that I do find interesting about satellite internet is that most users report getting more than the advertised download speed. This varies a lot, though. In general, you can expect a satellite system to turn in between 500 and 2500 kb/s.
Thus my theory is that if you actually needed satellite internet, you’d already have it. I would not recommend considering a satellite plan as a backup internet connection.
