The WiFi uploading Eye-Fi SD card made a big splash when it was first introduced, but now Eye-Fi has a whole line of different products. The top of the line is the Eye-Fi Explore, which supports geotagging without using a GPS. Instead of GPS hardware, it uses the Skyhook Wireless Wi-Fi Postitioning System, which correlates the position of the Eye-Fi’s access point to GPS locations, creating virtual GPS functionality. This allows photos taken with the Eye-Fi to be be geotagged. Of course, the accuracy of the system is noticeably lower than true GPS and seems to be affected by a number of external factors, but it is still accurate enough to tag the photo within the immediate vicinity of where it was taken.

WiFi positioning is great feature, but certainly not limited to photography. Since the Eye-Fi is at its core SD storage media, you could probably have it geotag data saved to the card, even if it wasn’t created by a digital camera..

In Car WiFi

June 26, 2008 by 8 Comments


You may have already heard that Chrysler is planning to provide in-car wireless internet access to its vehicles. If not, expect to hear more about it later this year when the requisite hardware becomes a sales-floor option, or next year when it becomes factory standard for some cars.

We can’t say it’s a bad idea, it’s just not a new one. Plenty of commercial portable routers are available, but they still need a modem and data plan to provide internet access. For internet access and wireless routing, look to [Nate True]’s cellphone-router combo, which uses a spare Nokia cellphone and a highly modded Wi-Fi router running OpenWRT. [True] has made it easy by providing the instructions and necessary custom code, but it seems like a lot of effort for a relatively slow connection. We think the original Stompbox is still the most fun since it has the speed of commercial devices and an open x86 OS to modify.

Confessions Of A Wi-Fi Thief

A wry editorial on Time Magazine’s site about tapping into your neighbors’ Wi-Fi tells of how the author [Lev Grossman] stole internet access from his neighbors’ open networks for years. He finally decided to pay for his own connection, which he fittingly leaves on an open network. He makes the point that leaving it open is a violation of his TOS agreement, but he doesn’t seem particularly bothered by the notion of people tapping into his network.

[Bruce Schneier] takes an even stronger stance on the issue, suggesting that it is not only safe to leave your network open, but a matter of politeness toward your guests, similar to providing them with basic amenities. He also mentions that if your computers are not adequately secured, network security won’t make much of a difference. We tend to agree with [Schneier] on this: we also leave our network completely open.

That’s not to say [Grossman] doesn’t have a point about the unreliability of pilfered internet access, noting “I always seemed to lose connectivity just when I was about to send a crucial e-mail.” Sure, we leave our network open, but we have to pay for our internet access. We really can’t afford not to. One thing [Grossman] didn’t mention (neither did [Schneier], but he wrote his article before this happened), is that a Maryland bill that would criminalize leeching Wi-Fi has been shot down. The first legislation of its kind, the defeat of the bill mean citizens of Maryland are free to leech from open networks without fear of prosecution, but it sets a precedent that may influence future rulings.
