When we go on vacation I figure if I’m in a car for 8 hours at a time, I might as well be doing something constructive! What’s
best way to stay connected? WiFi? Something else?
First: if you plan to use your computer while in motion I hope that you’re not the one driving. 
Second: WiFi is a great solution when stopping at rest stops that offer it, or at local coffee shops that have WiFi hotspots
along the way.
Unfortunately, WiFi is not a general-purpose, connect-anywhere solution; it has a very severe limitation that rules it out for
this connectivity as you drive down the road.
However, there is an alternative.

There’s actually nothing wrong with firing up WiFi in your moving vehicle, the problem is simply that with only 300 feet of range, there’s not likely to be anything to connect to. (We’ll look at one exception to this at the end of the article.) At best, you might get very brief connectivity to other WiFi hotspots you pass on the road, or the WiFi of others who might happen to have a computer running in their vehicles.
The current best approach to getting connectivity in motion, or without having to rely on WiFi hotspots along the way is to get a cellular modem and a data plan from your cell phone provider.
Cellular has two specific characteristics that make it perfect for exactly what you’re envisioning:
To begin with, the range of cellular signals isn’t measured in feet, it’s measured in miles. That means that you don’t need to be nearly as close to cellular towers as you do WiFi hotspots.
Secondly, your cellular provider has established a comprehensive network of cell towers that will provide you continuous and transparent connectivity as you drive along the highway. Before you get out of range of one tower the system “hands you off” to the next tower along the way, without interrupting your connection.
All in all, exactly like your cellular phone calls.
And this is exactly what I do.
I have a USB cellular modem from my cell phone provider that I can plug in to my laptop. Anywhere there’s cellular coverage, I get connectivity. And yes, my wife’s been known to work for an hour or two while I drive, heading up the highway. I’m very pleased.
There are laptops that actually include cellular broadband hardware, so you wouldn’t need an additional modem. I tend to shy away from them because just like cell phones themselves, they work with only one provider. If I want to change providers I simply get a new modem, not a new laptop. In addition, since I have several portable machines, my USB modem will actually work in any of them.
I alluded to a way that WiFi might be used, and it’s something I do as well: use a cellular WiFi router:
This device can be considered a portable WiFi hotspot that uses your cellular modem for internet connectivity. In a nutshell, you plug your cellular modem into one side, and the router provides a WiFi hotspot out the other. That hotspot is then available to any WiFi enabled computers in range.
Put that in your car, and you’ve got a moving WiFi hotspot.
It’s a great way to provide connectivity for more than one computer at a time, and for computers that, for whatever reason, can handle WiFi but not the cellular modem directly.
A friend of mine uses Verizon Global Satellite Broadband Internet Access. She is currently in Greece and it works over there. So long as you have a clear view of the southern sky you will get a broadband connection. The device itself is battery powered but comes with a power adapter. Only 11×15″ and weighs about 3.2Kg.

Google MIFI. This is esentially a combined cellular modem and 5 user wifi router so you can share your connection. (My Cell phone does not use “minutes” when a wifi connection is available.) These are pretty new at least one carrier has a “daily” plan vs monthly. F.Y.I. your carrier does not need to be teh same as your cellular carrier.
That is all fine and dandy but since I am not made of money, I would like to know what this rolling connection is going to cost me.

1) Lenovo tells me my “built-in” can work w/AT&T, Verizon etc
2) If you have a built-in that would only work with a specific carrier, that would not prevent you from using a USB modem.
3) Instead risking having of a USB sticking of the side of your computer, you’re better of with a plug-in card (Express Card, PC Card etc)
The above is in reference to your statement “There are laptops that actually include cellular broadband hardware, so you wouldn’t need an additional modem. I tend to shy away from them because just like cell phones themselves, they work with only one provider. If I want to change providers I simply get a new modem, not a new laptop. In addition, since I have several portable machines, my USB modem will actually work in any of them.”
To the poster who asked the cost… I pay $61.03 monthly for mine from Sprint. I use a Crandlepoint MBR1000 router which is an outstanding router. They also make more portable ones. You can also tether your Blackberry and/or iPhone and use it’s connection. I dont’ know the cost of that though…
Actually, I had mine built into my Dell laptop and then decided to go with a USB. That way I could put it in the router or hang it several feet away from the computer if I didn’t want to use the router. The USB modem comes with several feet of cord enabling better reception. I thought I would share this because my mistake was a costly one – hoping to help someone aviod that…
I’m in Canada and several of the cellular providers that I know about (Rogers, Bell, Telus, etc)have “USB sitcks”, going by various names. These are complete cellular modems in a “thumb drive” package that don’t require an actual cell phone tethered to a modem plugged in to your computer. I believe that’s what Leo, and possibly several others, are referring to but, because of the terminology, I can’t be sure.
Where available, this is a lot less hardware intensive, a lot less hassle and you can still make and receive calls with your cell while online with your laptop.
SpacemanBill mentions the ”USB sticks” easily available in Canada from various providers such as Rogers, Telus, Bell. These are excellent, so easy to use and work very well. I imagine that all major carriers in the US, UK, UE, Japan use the same technology. By the way, Leo’s article is excellent.
Dumb Question: I have a tablet that is WiFi (no 3G/4G or USB port). Is there such a thing as a portable Wifi device available?

You could get a cell phone that projects a Wifi spot, and then use the tablet off of that. So, yes, there is portable Wifi devices. I know that Verizon has them, probably other carriers too. You can even run a computer off a cellphone wifi.
I’m going to look into this this week.
From what I’ve read this seems like it is a bit expensive. I’m going to call Verizon and see if I can have my cell enabled to do this.
Thanks Everyone! AND a BIG thanks to Leo for all of his hard work! I learn so much here!! Love this site!!! 🙂
I’ve tried T-Mobile, ATT, and Verizon laptop connect..they all suck…if used in motion, especially in rural areas it keeps disconnecting and reconnecting while the car is moving..and when i try to view live video (sports, etc.), or download movies, all it does is buffer..when I complained to them, they Said they couldn’t guarantee a seemless connection..I wish they had something better
