ancy updating your Facebook status with “…is using Wi-Fi on the Tube LOL”? Well from next week you can do so without fibbing, because London Underground is switching on its first wireless hotspot next Monday, 1 November.
The six-month trial will include only one station – Charing Cross – and will deliver Wi-Fi access to anybody able to access the BT Openzone network. It won’t work on trains, but will be available in the ticket hall, and on the Northern and Bakerloo line platforms.
The idea behind the trial is to look at how Wi-Fi performs on the Underground, and also to observe the level of take-up among travellers. So what about you, London-dwelling readers? Do you plan on logging in while waiting for your next Tube, or do you treasure the brief respite from mobile phones and the like afforded by London Underground’s lack of connectivity? Let us know in the comments box below.

BBC E-mail: US frees 'super wi-fi' airwaves
The US broadcasting regulator has announced it will make unused television airwaves available for new "super wi-fi" technology. In a statement, the Federal Communications Commission described the spectrum between television channels as "prime real estate" for mobile devices. It hopes the move will turn swathes of the country into giant wi-fi hot spots. Officials also said it would encourage innovation and job growth and make the US more competitive globally.
"It will enhance our economy and strengthen our global competitiveness, lead to billions of dollars in private investment and to valuable new products and services - some we can imagine, and many we can't," Federal Communications Commission (FCC) Chairman Julius Genachowski said in a statement after the commission's unanimous vote. The FCC said the move marked the first time in more than two decades a large band of spectrum had been opened. The airwaves became vacant last year when the US moved to an all-digital television broadcast system. Technology firms are eager to begin using the airwaves, in part because signals in that spectrum can travel several miles, penetrate walls and allow large transfers of data. The move came after several successful pilot programmes across the US, Mr Genachowski said. Wilmington, in the state of North Carolina, for example, has experimented with "smart city" applications to manage traffic and water quality.
Some broadcasters fear the move will interfere with their operations, including wireless microphones used to report news.

Trying Out Wi-Fi in the Sky
PRACTICAL TRAVELER
Trying Out Wi-Fi in the Sky
By BOB TEDESCHI
Published: June 18, 2010
Leif Parsons
Yes, a Skype call. No, it didn’t last long.
“Hi, honey!”
“Hey! Where are you?” she replied.
“Over the Rockies I think.”
“Is everything O.K.?”
The Internet connection to my laptop went dead, and it occurred to me that she might have thought something was wrong on the flight, if I were risking what she believed was a cellphone call. I quickly tried using Skype again but failed.
I sent a quick e-mail message letting her know I was playing with Virgin America’s in-flight Wi-Fi system, and we spent the next half hour sending instant messages. I followed that up with a few solid hours of e-mailing and online research, with some detours through Facebook, YouTube and ESPN.com.
It was like a normal day at work, in other words, but for the fact that I was at high altitude, and being served food by cheery flight attendants. I left the flight feeling that the $10 Wi-Fi charge was well worth it, even with the Skype glitch.
In-flight Wi-Fi is not yet a commodity, but it is no longer a rarity. Most domestic airlines have been upgrading their fleets to offer the service more widely, to the point where nearly one-third of the roughly 2,800 aircraft in the nation’s passenger fleet are equipped with Wi-Fi, according to Aircell, the company that equips most of the Wi-Fi-enabled planes in the United States.
If you travel on planes a lot and plan to use Wi-Fi frequently, you can shave some expense from the process if you have a Wi-Fi-enabled mobile device like an iPhone or Droid, which incur lower charges than the fees charged by airlines if you use a smartphone or laptop without Wi-Fi. If you don’t have your own device, airlines are not yet providing one.
But no matter what device you use, the connection process is fast and usually pain free.
Among the better-known airlines operating in the United States, Lufthansa is generally acknowledged as the first to offer Wi-Fi, which it did through Boeing’s Connexion service, starting in 2003.
While Connexion shut down in 2006, Aircell’s Gogo service steadily gained traction with domestic United States carriers so that now, of all the domestic aircraft currently offering Wi-Fi, all but one carry Gogo service. The exception is a single Southwest Airlines plane (so far) that might signal the entry of a new Wi-Fi competitor, Row 44.
Connecting to the Internet during a flight is the same, no matter which service you use. You log on, open an account and type in your credit card numbers. On the flights during which I tested Gogo, the process involved a lot of typing, so connecting through a laptop was far more convenient than doing it through a smartphone. But Michael Small, Aircell’s chief executive, said that the company is streamlining the process so that non-laptop users can save time.
The few times I used the service in the past year, all on Virgin America, I experienced no lost connections or slow downloads. The general rule is that you can connect at 10,000 feet, or about 20 minutes into the flight; the service automatically shuts down during the descent.
Gogo and Row 44 executives said that their services operate with roughly the same speed and stability. And both companies allow airlines to block pornographic sites. (All carriers do.)
But some passengers may notice a more unfettered surfing experience with Row 44. On Gogo, users who try to download huge amounts of high-definition video will lose their connection after a certain amount of time, depending on how many users are online. Mr. Small, Aircell’s chief executive, said that is Gogo’s way of keeping the network performing smoothly for everyone on the plane.
Row 44, however, puts no such constraints on passengers, so if you want to download high-definition video continuously for the entire flight, you may.
All of Gogo’s airline partners charge the same prices for those with laptops, iPads and netbooks: $5 to connect for 90 minutes, $10 for three hours, and $13 for more than three hours. Passengers with Wi-Fi-enabled mobile devices pay the same $5 for under 90 minutes, but they pay $8 for anything beyond that. A one-day pass is $13, no matter what device you have, and a one-month pass is $15 for Wi-Fi users with mobile devices, and $40 for laptops.
Row 44 has not yet set prices.
The domestic carrier with the greatest number of Wi-Fi-enabled planes is Delta, with nearly all its 500 planes offering the service. American has installed Gogo on more than half its fleet, including 150 MD-80 aircraft and 15 of its 767-200s. AirTran’s entire fleet is Wi-Fi-enabled, as are planes used for longer flights on US Airways.
On United, Gogo is on 13 planes that fly the routes between New York and San Francisco and between New York and Los Angeles. Continental, which last month said it would merge with United, has none.
Virgin America’s entire fleet of 28 planes has the service, and Alaska Airways will follow suit by the end of the year.
Unfortunately, if you are flying internationally with a Wi-Fi-enabled device, your chances of logging on during a flight have been virtually nonexistent since Connexion shut down. Lufthansa said it would soon restart its Wi-Fi service but offered no details on timing or routes. (Oman Air offers in-flight Wi-Fi for $10 to $30, depending on how much data you use, or $5 for online chatting, and Air Canada offers Gogo wireless service on two flights.)
But inside the United States, given that some airlines have only a few Wi-Fi-equipped planes and some have a lot, how do you know if your next aircraft will be technologically blessed?
Unless you fly on Virgin America or AirTran, which offer Wi-Fi on every plane, you may face some guesswork. American posts a “Wi-Fi” icon next to the online flight information 24 hours before a flight, and US Airways and United post similar symbols at the time of booking, but Delta has no such notification methods.
Southwest will send e-mail messages to passengers before a flight to let them know they’ve got lucky aircraft No. 910, the fleet’s only Wi-Fi-enabled plane. Whitney Eichinger, a Southwest spokeswoman, said the company would unveil “more formal” notification when it adds more Wi-Fi-equipped planes this summer.
One thing that won’t vary among airlines with Wi-Fi is their policies about using Skype.
Other countries are cavalier about cellphone chatter on airplanes, but domestic carriers in the United States don’t think passengers will accept such noise at high altitude, so they block such technologies.
It turns out that I had tested the system before Virgin’s Skype-blocking technology was in place. So I have the distinction, for what it’s worth, of being among the few to sully a flight with a Skype chat.
For those seated nearby who believed they had caught a glimpse of a noisy future, it was thankfully brief — and my exchange with my wife quickly yielded to the hum of the engines, the buzzing of audio headsets and the clatter of keyboards.

Wi-Fi at 60 GHz Will Be 10 Times Faster
The Wi-Fi Alliance and the Wireless Gigabit Alliance have reached an agreement to set up standards for Wi-Fi to operate in the previously unclaimed 60 GHz frequency band, which would offer up to 10 times faster data transfer speeds. Currently, Wi-Fi operates in the 2.4 GHz an 5 GHz frequency bands.
”The 60-GHz band allows for significant boost in performance, so we are talking about speeds in the gigabits per second range,” says the executive director of the Wi-Fi Alliance, Edgar Figueroa.
Unfortunately, the new standard would come with severe drawbacks; Wi-Fi signal operating in the 60 GHz band would not be able to penetrate walls; one would need to have line of sight for a decent connection. However, the increase in speed is so significant that the trade-off would definitely be worth it in certain situations.
It’s not going to happen overnight, though. After the standard is set, consumers will want routers and wireless adapters that can switch between two or all three (2.4 GHz, 5 GHz and 60 GHz) Wi-Fi frequency bands. Figueroa estimates that these will be available on the market in about two years.

How To Deploy An Open Area With Wireless
Whether you provide wireless as a courtesy or use it as a money-maker, there are definite do's and don'ts to setting up and sustaining a usable local wireless environment where many clients will rely on it.
There are also no hard and fast rules and individual wireless access points have different features but the general principles of AP placement are well understood. Regardless of the wireless access point vendor you use, follow these steps for a successful deployment.
Up-front analysis is key. Have a scale drawing of your area so you can map out your AP placement. A free tool like Meraki's WiFi Stumbler will help any environment size up neighboring wireless networks that need to be worked around by showing adjacent network names, channels in use and how strong they are being felt in your space. Once you map the airspace, you can design your own access point placement. Remember that your airspace will change over time as neighbors add or remove their own access points, but you can adjust your network as needed.
Estimate how many users are going to be on the wireless network at a given time. If more than 15-20 users might be on the wireless network at the same time, you'll need to plan for more access points even if just one can fill the given area with signal. Wireless is a shared medium and when you get over 20 simultaneous users, contention will become a limiting factor in performance.
Determine the minimum throughput you'd like to provide. 802.11 a/g offers upto 54Mbps while 802.11n can reach, in theory 600 Mbps (though actually data rates will be much, much lower). The data rates will increase and decrease based on conditions in the airwaves. Balancing the data rate and number of users is a tricky process. Web and mail traffic might be considered lightweight, but a single YouTube video is usually around 500 Kbps. Consider what your users are likely to be doing; 10 users all streaming video might max out an 11g access point, for example.
Map out the size of the area do you need to cover. APs are usually "rated" for open areas when distances are claimed. You might get 200 feet of good signal outdoors, but only a couple of rooms inside. Construction materials make effective wireless barriers, particularly in older buildings where metal screening was often used to hold plaster. Verification is a must. If you see signal falling below 70 dBm, you need another AP. You don't need to have your AP blasting at full power either. If you are at an edge, try adjusting the power levels so that you have adequate power for your area, but are also being a nice neighbor. It's also a good time to go talk to your neighbors who are using maximum power to see if they can turn it down a bit.
