WiFi is an established wireless Internet technology. It is established because there is a WiFi workgroup which certifies wifi hardware and sets the specifications for every new rendition of the technology. It is important to note WiFi was, and still is, meant for local area netowrking (LAN). To this end, it is not meant to connect you to the Internet at great distances. Most wifi hardware gives you a wireless connection between 100-500 feet (this is an average).
WiFi security, or the lack thereof, is a misnomer. WiFi has a number of security options to help you secure your wireless connection to the Internet. It is true if you do not secure the connection or use the basic security (WEP), the opportunity for nefarious activity may be higher. However, you must consider a wifi connection is a short-range technology and a potential breach by hackers can only be achieved by someone being within range of your wifi hardware. Regardless, if setting up your own wifi network you should consider using WPA or WPA2 for securing the network. In the very least use WEP for basic security and try not to be liberal about who you give the passcode to.
Here at WiFi.com, we are creating an environment in which you can secretly share your WEP passcode with friends on various social networks and your email contact lists. This is one of a number of features we are working on here at WiFi.com - check back often to learn more. Also, check out our support forum.

When it comes to the 802.11 standard (WiFi), there are two types of security, which can be deployed on the wireless network. The most common and least secure method is Wired Equivalent Privacy (WEP) and the much more secure Wi-Fi Protected Access (WPA). It is important to note: Independent research conducted by wifi.com staff indicates better than 50% of home-based wireless networks and 40% of wifi hotspot providers do not deploy security measures.
For home-based and most other consumer-grade wireless networks, security is controlled at the access point or router. The current security settings on wifi-capable access points are; none, WEP, WPA, and WPA2. The key difference between WPA and WPA2 is the latter applies an Advanced Encryption Standard (AES), which has been adopted by the U.S. government.
In general WEP security will keep the average person from using your network. However, in August of 2001 a published article explained how the WEP encryption can be attacked and the passkey recovered in about 10 minutes time. Thus, if someone really wants in, they can gain access to the network and ultimately, your computer.
When securing a home network, wifi.com recommends using the WPA2 (AES) option. With the adoption of the next 802.11 standard (802.11n) the creation of a secure environment using WPA2 (AES) will become easier for the end user.

DeFi's VoIP Offering: Flat Rate, Worldwide, and Integrated - Startup VoIP provider DeFi makes big claims, but delivers worldwide calling from a smartphone for $40 or $50 per month: DeFi has a very stripped down business model designed to appeal to a specific, but large class of traveler. They make software that's currently available for Nokia S60 phones (E and N series), and later this year for the iPhone, that acts as a kind of VoIP shunt for calling behavior. When you place a call, the software determines whether you're on a Wi-Fi network, and routes the call out that way; if not, it goes to cell. It also routes inbound calls, and can ring your cell phone's number if you're not on a Wi-Fi network and your inbound DeFi number gets a call. For $40 or $50 per month (1 or 3 inbound phone numbers, respectively, in any of about 30 countries), you get 3,000 minutes (they call it "unlimited") of calling to and from 75 countries. This includes cell lines in Europe, typically a huge extra for most VoIP plans. DeFi said they signed deals directly with carriers, which they say most VoIP providers have not. Wi-Fi access works at what they say is "1 million" hotspots, but is really Fon plus several tens of thousands of typical hotel, café, and airport venues. Wi-Fi fees are included for VoIP and data in the monthly subscription. DeFi uses Devicescape behind the scenes to handle no-entry authentication to their Wi-Fi footprint. The integration is the key point DeFi makes about their product, and may be a stumbling block for an iPhone application. The head of DeFi told me that the company wants their service to require no behavioral changes for customers. Of course, users still have to make sure when they're in areas in which a cell call would be expensive that they don't accidentally wander away from a Wi-Fi hotspot. And Apple doesn't currently allow the kind of integration that would be required for call handling and interception, although DeFi said it's having no problems in its development work.

SNCF Promises Fleetwide Service for TGV Lines by 2010 - SNCF in France says they'll install Internet service on their entire TGV fleet by 2010: We've seen this promise before, so excuse me if I'm a wee bit dubious about the French train operator SNCF's claim that the service will span all their equipment. Despite Internet access over Wi-Fi being available on several train lines in Europe, including multiple lines in the UK, the biggest announcements always seem to fizzle out. The Dutch train operator was supposed to unwire their fleet a couple years ago and backed away, for instance. SNCF says they'll have for-fee service in 1st and 2nd class areas of TGV trains by third quarter 2009 in some trains, and full coverage in 2010. These high-speed trains cross borders in all directions. A free portal will be available for information and entertainment access within a train. Fees for access might cost €5 to €10, which is outrageously high, unless you compare it to the very high costs of Wi-Fi across Europe, where you can pay US$30 or more for 24 hours access in some hotels.

Virgin Announces Launch Schedule - Virgin America has formally announced their in-flight Internet launch and plans: Virgin put out the news a few weeks ago that they'd have a press event flight on 22-November to show off their in-flight Wi-Fi with GoGo (AirCell's branded service). They're now formally noting that service will start for all flyers on a single aircraft 24-November, and expand to their entire fleet by second quarter 2009. Earlier reports indicated the airline would equip about one plane per week, which probably conforms to overnight maintenance schedules for their fairly new planes. Virgin America goes quite a bit beyond other airlines in the electronic amenity department. They have an advanced seat-back system that includes in-flight chat (currently intra-plane, soon across the fleet as Internet access is added); it's gotten rave reviews. They also have power available at every seat, which is an easy choice to make when you're building planes for today's passengers. I'll be on the press event flight, covering it for a few publications including this fine site, and will try to blog from the air just for the fun of it. If you can blog from the top of mountain, it seems necessary to do so. (Disclosure: I'm paying for all my expense associated with getting to and from the press event.) Virgin America is the only airline worldwide that's committed to putting Internet service on all its planes, although it has a fairly small fleet. (Planespotters has the full list of 27, including their names, such as the BoingBoing-plumed Unicorn Chaser.) For a mainstream media article I'm writing, I'd love to hear the experience of anyone who has used American Airlines' GoGo service, which has been in operational on long-haul 767-200s for the last few months.
