WiFi in Your Rental Car

Jezebel writes "Avis is bundling a 3G-to-802.11 bridge with their rental cars that will turn the vehicles into WiFi hotspots. Will we now have to worry about laptop use on the Interstate?" From the article "Autonet Mobile CEO Sterling Pratz told the International Herald Tribune that the In-Car Router will function in around 95 percent of the country, including all major US cities. Pratz claims to have minimized the problem of dropped signals with a technology similar to that used by the space shuttles to maintain an Internet connection."

The Killer App

[ukemike]

The killer app for this will be to add real-time traffic conditions, and traffic cams, to the GPS mapping system in your car. Every day on the way home I exit from the freeway one exit early because about 20% of the time traffic is backed up and it takes 30 min to get to the next exit. When traffic isn't backed up staying on the freeway saves 10 minutes. But for me arriving at a predictable time is more important that trying to beat the odds. If I could access a traffic cam from my car a few minutes bef

Re:

[kkwst2]

Maybe not. Traffic jams are interesting beasts. If traffic can be diverted as soon as the accident happens, then the congestion might be minimal. It would be easier for emergency vehicles to get there and take care of business, and the jam may never materialize to the extent it does now. Most of the time when you get to a traffic jam, the instigating event has long been cleared and you're dealing with the residual mess which can last for hours. If 75% of that traffic could be diverted soon after the in

Re:

[Ollierose]

A better approach might be to follow the example of the motorways in the UK - they have overhead signs with a matrix to display a road sign (perhaps an altered speed limit) along with a reason for the altered limit. An example might be that it says "50 (surrounded by flashing amber lights) Queuing Traffic Ahead". These are usually a couple of miles apart, so they won't catch everything.

Around busier interchanges, there is an overhead gantry with a smaller matrix per lane, which allows police to advise traff

I was driving in the UK on the M42 the other day, and I passed under one of these, about 2 meters away from it it changed, I was too close to see what it changed to, but right after it is a variable speed Camera .. I'm waiting to see the ticket and the driving ban for being 20mph over the speed limit.

Re:

[ShannaraFan]

Here in the US, the reaction to a sign stating "Right lane closed ahead" would be two-fold:

- 25% of the drivers seeing the sign would be confused, coming to a near stop on the freeway while they ponder the meaning

- 25% would dive to the breakdown lane, accelerating around everyone so that they can be the first on in line at the merge point

- 25% will do nothing, staying in the right lane until they reach the closure point, then will sit there with a turn signal blinking, waiting for someone to let them over.

Regulation

[denebian devil]

Well, many states have taken to banning cell phone use in cars by drivers, or at the very least cell phone use that isn't "hands-free." It's possible they could do the same thing with computers/internet use. Though considering how long it took for those laws to catch up to the reality of cell phone use on the road (assuming you believe they even have caught up yet), I have to wonder how many accidents will happen before such laws manage to get on the books.

[Silver Sloth]

I don't know about the US, and IANAL, but here in the UK there's the offense of 'Driving without due care and attention'.

C'mon, that case was "a person who was well known to deserve it": http://news.bbc.co.uk/1/hi/wales/north_west/478568 6.stm [bbc.co.uk]

Mrs Donna Marie Maddock also had her license suspended for 20 months for an alcohol related offence just before being handed this ban and these points. Whatever the courts and BBC tell I bet that the magistrates handing out the ban actually knew who is getting it and the list of her previous (or in processing) offences. In fact they definitely knew, because her solicitor has asked the judges to reduce or waive the ban because she was already serving one (the best example of Chewbacca defence I have ever heard of).

We have laws like that (in most places) here in the U.S. as well, but enforcing existing laws doesn't let the politicians demonstrate how freaking "in-touch" and "useful" they are. Thus, we get nonsense legislation every few years. Solving problems that don't really exist or that ought to be covered by existing laws already is a favorite.

[Bloke down the pub]

We may talk funny in olde England town, but we're not entirely stupid. We've had a law on the books for some time now about "driving without due care and attention". Yes, it's vague. Yes, it's a catch all. Yes, it requires some element of judgement from 1) the driver 2) the police and 3) the justice system. And we can't be having any of that now, can we?

No no no, much better that the law tries to define exactly and explicity what you can't do while driving a motor vehicle. Let's see, item 2647a - watercolour painting, 2647b sketching with a pencil ... 2648a playing a trombone...

[wsanders]

I have heard it told that the speed of a moving car is enough to screw up US digital broadcast TV signals. And it has to be taken into account for GPS reception (well the sats move much faster than most everything on the gound canmove...)

So why would doppler not be a problem with WiFi? I'm just thinking out loud here...

Here's the math:

[wsanders]

In 2 dimensions, a reasonable approximation for a radar gun, or if you are driving directly toward an RF source, the ratio of the shift is 2V/c. At 100 fps, that's about 2E-7, or a couple dozen Hz at 100 Mc. This is how doppler speed guns and doppler radar work, and they can easy pick out speed variations of a few MPH. For GPS there is much less effect because the sats don't move directly toward or away from the observer, but, still, as I understand it, some GPS units can measure the phase difference (http:

It's only a matter of time before 3G follows the same distribution pattern laid out by the original analog cell network, later followed by the switch to digital.

Coverage first starts out in the major metro areas and works its way out to the suburbs of the largest cities, and especially those that are "centers of commerce.

alternate to municiple wifi

[v1]

This would be an interesting way to solve the problem of municiple wifi. If even 5% of the cars in a city were functioning as short range wifi routers, and if they were using tech similar to cell phones how they hand off seamlessly from tower to tower, that would be a really elegant way to network entire cities. No need to plant towers like dandellions, no problems with dead zones due to buildings, etc. I'm not thinking of people browsing web while in their car, but imagine being able to use voice or video chat (think iChat) while driving down the freeway, your car reading you a new email as you sit at a stoplight, or being able to take your laptop to the park and know there are a dozen hotspots within 300 feet of whatever park you pick. I hope this takes off.

Better than that. If *your* car is operating as a wifi hotspot. It follows *you* around. Making it much easier for *you* to get internet access.

Will we now have to worry about laptop use on the Interstate?

Yes, because the first application I think of when I think of riding in the car is a surfing the web on a laptop. This is a step further in a persistent connection to caches of information on the road. We're pretty much limited by GPS, commercial radio, cellular and CB communications. Let's get out of thinking that a computer is something you sit at and type. Multiple devices can take advantage of a persistent connection on the road. A networked car computer will either enhance or replace already existing information channels (like the ones I previously mentioned). And supply a few more; think of automated driving and distancing through wireless arrays. Traffic systems that can 'predict' with greater accuracy when cars need the lights changed or the railroad crossing sign lifted. Anyway, Yeah, people will use it to download iTunes (is that a bad thing), but let's get beyond the old man sitting at the terminal inputing text at a keyboard. That is SO twentieth century.

Using a Wifi device in a car

[MosesJones]

There are several things here to consider.

Firstly Wifi != Laptop, this could enable things like Google Earth sat images to be downloaded in real time to your Sat/Nav system, it could be used to switch your mobile to VOIP rather than using a cell, it could be used by the cars Radio/CD/iPod player to offer you new tracks.

Secondly the person driving doesn't have to be the person working. Last year myself and a friend drove from San Francisco to Las Vegas, with a bunch of work to do we split the driving and use a car-charger adapter for the laptop, we got a good 10 hours of work done and an internet connection would have made that a lot better.

Thirdly this also means that Avis can start flogging you added extras that work on Wifi, which is cheaper than 3G connected devices.

My big question though is do all those cars have different SSIDs and will they be WPA and greater protected? If I'm connecting up to a network then I'd prefer people not being able to hijack my devices, some SatNavs can already be bluejacked and this could make it miles worse.

Re:

which is cheaper than 3G connected devices.

To quote the summary:

Avis is bundling a 3G-to-802.11 bridge with their rental cars

Re:

Yes it is doing that, which means that in the car you have 802.11, and that connects to the internet via 3G. This means there is ONE device that is 3G based (expensive hardware) and lots which are 802.11 (cheap hardware).

I'm sure you have a point, but I'm missing it.

Re:

[mlk]

The expense is getting data, the data is still coming over the 3G network (i.e. still very expensive).

I think I've misread your post, and you are talking about lots-of-WiFi kit talking to a single bit of 3G kit, rather than having lots of 3G kit. But I don't see when that would be the case, you normally have one bit of 3G kit, talking bluetooth to the other net-enabled kit.

I went to Las Vegas over Christmas because nothing says Christmas like Vegas... As partof ourpackage deal we had a car rental from Avis. After arrivig, we took the 10 min bus ride to their area and were directed to one of 10 or so kiosks for service.

While this works for the most part with airlines, it blows for people flying in at 11pm. There two real people on duty with a line of about 50. The kiosks wouldn't pull up anyone's info and directed you to go to the counter instead.

After waiting in line for over an hour, I was told that the kiosks are down. Awesome, direct me there when you know full well they don't work.

So, if they can't keep their kiosks running, I can't only imagine what their 3Gwifi will be like.

Massive adhoc network

[Trashhalo]

Semi off topic but I have been thinking about this lately. Why aren't all cars equipped with wifi? Traffic on highways is normally dense enough to give you a adhoc connection to any other car in the state. I dunno what you would do with that connection but it would be really cool. Some simple ideas it could provide ways to inform other drivers in your local network of accidents and delays. I am sure other people could come up with more interesting uses of such a network.

Make it work like car TV's

[phorm]

Car TV's that have been installed properly, will, if in viewable range of the driver, disable the screen while the e-brake is off. That gives the driver the ability to watch shows while parked (good for, say, truckers or distance-drivers that want a break), but does not allow for watching-while-driving (unless one wants to grind the e-brake down to the nub). Of course, many shops and self-installs bypass this by attaching the safety connector to ground. My car has a DVD player, but the screen isn't installed by default so the safety is disabled. When I have passengers who want to watch, I just pass them back the screen and some headphones (my JVC unit allows them to watch/hear the DVD, and me to plug an Mp3 player into the deck-amp so I can still have my own tunes).

However, I believe that by law, a screen visible to the driver is/should be disabled when the e-brake is off or perhaps when the vehicle is out of park if possible. Applying this to wifi wouldn't be too difficult either, especially if this is a factory install.

I must ask though, why do you need wifi in a car? If you need a laptop signal then an ethernet jack in the center console would work fine, even if it is piggybacking on a wireless system.
