Banjo has three main goals. One is to connect you to your social networking friends you didn’t know were nearby – for example, a friend from Facebook or Twitter, killing time at the airport, only a few gates away from you. It also wants to hep you find out what’s going on nearby by providing access to status updates and tweets from everyone around you, in a radius you specify. And it provides you with a way to virtually visit other locations, even when you’re far away, to see what’s going on with the people there.

The people Banjo finds don’t necessarily have to have “checked in” using a location-based networking service like Gowalla, Foursquare or Facebook Places. While that helps, of course, Banjo is designed to also pull in locations from geotagged tweets, uploaded photos, and other media from all social networking services. Wait – all? Yes, that’s the plan. Patton says they have 22 services they’re focused on integrating now, but the company’s goal is to become a federation of all social networks, big and small, from around the world.

A research team at the Chalmers University of Technology in Sweden has come up with a new optical amplifier that can help boost the efficiency of backhaul optical networks, a move that could have a big impact on the overall economics of bandwidth.

Chalmers’ new breakthrough is more efficient and allows optical signals to be sent over longer distances 4,000 kilometers as opposed to 1,000 kilometers – which in turn would make the cost of building and operating the networks cheaper.

“The entire optical telecom industry is our market. But the technology is generic, and scalable to other wavelengths like visible or infrared light, which makes it attractive in areas such as measurements, spectroscopy, laser radar technology and any applications where detection of very weak levels of light is essential”, says Peter Andrekson.

From Libelium: Libelium, a technology leader in wireless sensor networks, announces the completion of its Smart Cities platform. The new sensor board measures noise pollution, dust quantities (PM-10), structural health (cracks detection and propagation) and garbage levels in bins in order to improve the waste management. This board may be combined in a network with previously available sensor boards for gas monitoring, radiation detection and Smart Parking. System integrators can now create a comprehensive range of services based on the Smart Cities platform. Read more here.

How would you feel about an iPhone app that claimed to be able to tell if that mole on your arm was not looking too healthy? That’s the claim of Skin Scan, an iPhone medical app available now on the Apple App Store. The startups has secured €50,000 Euro in seed funding from Seedmoney.

E-readers are outpacing tablets by a rapidly widening margin, Pew said in a new study. After a brief amount of parity for the second half of the year, e-readers doubled from just over six percent ownership in the US last November to 12 percent this May. Outside of a brief spurt during the holidays, the growth of the iPad and other tablets kept the same pace and rose from five percent to eight in the same period.

Overlap between the two was significant: three percent had both. Nine percent of Americans have just an e-reader and no tablet, where only five percent have just a tablet.

In spite of the adoption, either category still trails well behind others, Pew says. Thanks to about ten years of Apple's own efforts with the iPod, 44 percent of the US has an MP3 player. More than half have a computer or a DVR, and 83 percent have cellphones. Notebook PCs are now virtually on par with desktops for popularity with just one point of difference between the two.

If there’s one thing Twitter users know, it’s that advertising is coming — and not just a few “promoted tweets” or “promoted trends” here and there, but actual branded advertisements appearing right in a user’s real-time stream. There have been several recent reports that ads will be rolling out soon, including a Reuters report that says Twitter is planning a trial of “self-serve” ads for major corporations. There’s no question that the company needs to do bring in revenue, but how will users of the service react to the sudden appearance of advertising in their streams? At least one analyst thinks that Twitter is making a big mistake.

Their solution to competing with their larger (more supermarkets) competitor was to create virtual stores using large wall spaces in subway stations that are full-size photos of their supermarket products. Customers use thei smartphones to scan QRcodes to a virtual shopping cart. Once the order is complete, the items are delivered directly to them after they arrive at their homes. Homeplus: Virtual Subway Store (WeLoveViral) More than ten thousand customers visited the online store using their smartphones. New registered members rose by 76% and online sales rose 130%. This marketing and sales technique increased their sales without increasing retail store space. And, it made shopping more convenient for busy people. Thanks to Megan O’Neill for the pointer to this great mobile story.

Google Ventures has quietly invested in a stealth startup called Wingu, reports StrategyFacts (subscription required). Indeed, while the Google Ventures website lists four career opportunities for one of its portfolio companies located in Cambridge, Massachusetts without naming Wingu, the stealth startup published the exact same job openings on its job board, leaving nothing to the imagination. Wingu is building a enterprise-grade cloud platform dubbed Elements that will enable research teams to collaborate more effectively and use data in ‘new ways’. Here are the four main selling points of Wingu’s platform, according to its website: MANAGE: Unify your cross-discipline teams on a common platform to share data and ideas. ANALYZE: Drive decision-making with our analytical workflows and discovery tools. SHARE: Connect your researchers across silos and geographical divides for better collaboration, coordination and communication. PROTECT: Breathe easy knowing that your data is backed and protected by leading systems and security experts.

Mobile payments have taken off in the last few years, and are now poised to grow from $240 billion this year to $670 billion worldwide in 2015, according to Juniper Research. Fueled in part by the nascent near field communication (NFC) market, which is expected to be worth $50 billion by 2014, the overall mobile payments market is also expected to rise quickly thanks to mobile ticketing, money transfers and purchases of physical goods. Mobile payments are more reliant right now on digital goods purchases, which is expected to double by 2015 and will account for 40 percent of the market. But the faster growth will occur with NFC, which can be used in retail and merchant locations to buy physical items. Juniper said 20 countries are expected to launch NFC services in the next 18 months.

Zoosh is a new technology that brings NFC-like payments to any phone with a speaker — i.e. every smartphone on the market.

Using the almost-inaudible 20,000KHz range — which almost every cell phone speaker is capable of — Zoosh technology can then send data to a receiving microphone. The end point can either be a point of sale — a shop, a ticket machine — or it can be another mobile phone. Apparently the technology has been successfully used in noisy environments — and it’s also fairly safe to assume that a technology like Zoosh would be designed to incorporate as much redundancy and error checking as possible.

Narrate, the company behind Zoosh, envisions two main use cases for its ultrasonic payment system. The first is just like Google Wallet: for $30 — a third of the price of NFC hardware — Narrate says that points of sale can be upgraded to accept Zoosh payments.

The global optical networking market is estimated to reach revenues of $20 billion in 2016, according to analyst firm Ovum. The global market is forecast to grow at 6% CAGR between 2010 and 2016, driven by investment from carriers in 40G and 100G networks. This level of growth, however, will vary according to region, with the North American market, for instance, estimated to grow by 12% this year while the Asia-Pacific market is predicted to contract by a further 3.2% in 2011. “Increasing bandwidth from residential broadband networks, mobile networks, and enterprises is the key driver of the growth. Carriers are investing in access networks and mobile long-term evolution (LTE) roll-outs are beginning to gain momentum,” said Ovum analyst Ian Redpath. “The optical networking market is also reaching a watershed moment in terms of technology. Networks based on 40G and 100G wavelengths are now poised for mass-market deployment.”

The game’s basic concept may sound familiar: you are trying to help your team take over the world. But we’re not talking about some fantasy realm or alien planet here. In Shadow Cities you’re trying to take over the real world.

Right there on the screen you will see other nearby players in real time, and not all will be friendly. When you start the game, you must choose between two factions, the Animators (nature lovers) and the Architects (technologists).

when you read an alert from another player that a big battle is brewing in, say, Paris. You jump to a friendly beacon and the next thing you know, you’re lobbing spells against enemy players from all over the world for control of the Champs-Élysées

That viral growth is deserved, too. Turntable.fm is arguably the most interesting social startup to emerge in a long time. Inventing a new subgenre, ‘social listening’, the site revels in something humans have enjoyed for millennia: shared experiences around music. If you haven’t tried it yet, here’s how it works: You can only sign up if a friend of yours on Facebook is already signed up. Once you’re in, the site lets you DJ, playing songs in an on-screen ‘nightclub’. Others come to listen to you in your ‘room’ and can join you on the decks if they choose. Multiple DJs (up to five) play a song each in turn and everyone else in the room gets to vote on the current DJ’s choice. If your choice gets voted up, you get a point. If it gets voted down by too many people it’s ditched for the next DJ’s choice.

when DJs demonstrate that they’re listening to each other by playing off each others’ track selections, there’s a commonality that transcends… individual achievements. Social games that offer the promise of individual success may be missing out on the uniqueness of shared experiences capable of creating shared surprise and pleasure. As when tracks flow well, as when it’s clear that DJs are not just picking their own favorites but show that they’re paying attention to each other, as when a “good” stretch of DJing attracts newcomers to the room, and so on.

A new way for media companies to interact with their audiences: Earlier this week, we experimented with setting up our own The Next Web room (you can often find TNW staff spinning tunes in there). One tweet brought in a crowded room and it was fun for us to be able to play music with our readers. Music is a brilliant bonding tool and being able to have direct group chat with readers can help media companies get to know their audience better, and vice versa. I even got teased with knowledge of a stealth startup over the chat function yesterday – so maybe we’ll get a few news tips this way too!

The cool kids of today - yes, the same kids who will be voting in the 2012 election - don't want to talk about infrastructure. Instead, they want to talk about mobile devices, crowdsourcing real-time data and collaborating via high-tech RFID sensors. They don't want to think about massive government expenditures and cheap bank loans for new construction projects. They think about cool ways for The Internet of Things to empower everyday citizens.

Mobile games are the most popular type of apps amongst smartphone users, according to the latest report by Nielsen.The report shows that 64% of users who downloaded an app in the past 30 days have downloaded a game.Weather, social networking and apps that fall into categories of maps/navigation and search are also very popular apps, followed by music and news apps, as you can see in the chart below.

Eyeing a shift in consumer habits, eBay has announced it is buying Zong, a provider of payments through mobile carriers, for $240 milllion.

“Commerce is changing. With mobile phones, we walk around with a mall in our pockets. PayPal helps to make money work better for customers in this new commerce reality –- no matter how they want to pay or what device they’re using,” said Scott Thompson, president of PayPal. “We believe that Zong will strengthen this value by helping us reach the more than 5 billion people who have mobile phones, giving them more choice and security when they pay.”

The event, held on 27 June, showcased the latest research on next-generation body-centric communications – wireless networks worn on the human body. Future communication systems will be worn on clothing rather than held in the hand as smart phones are nowadays, and will be made possible due to cutting-edge advancements in wearable electronics. Dr Paul, from the Centre for Communications Research (CCR), specialises in the design of antennas that can be integrated into textiles through electromagnetic numerical simulation. Applications range from smart clothing for sportswear, to soldiers’ and emergency workers’ outfits, and to monitoring devices for healthcare and telemedicine. Professor Joe McGeehan, Director of CCR, said: ‘We are delighted that Dr Paul has had the opportunity to present an invited paper on her novel research is this key area. Wireless networks worn on the human body will become more pervasive, particularly in applications such as medical sensor networks for an ageing population and healthcare.’

canning that mysterious QR code sticker that someone stuck on the wall in a tame but oh-so-technophilic act of modern vandalism.

Instead, the nasties are using QR codes to lure people into downloading Android malware. While some users are likely to assume that QR codes are unique to the Android market and thus be comfortable scanning them, these codes actually take you to an Android install package hosted on some third-party server. The QR code itself isn’t bad — but the link it’s obfuscating is.

Once downloaded, the dirty app (which, in the most recent case, was a hacked version of the Russian ICQ client, Jimm) begins firing off text messages to a premium number. Each text it sends (without your knowledge) sets you back around $5+. You can find an outline of the method by Kaspersky Labs here.

“We want to build tools that change the way all the people in this room experience the real world,” said Foursquare founder Dennis Crowley at the Web 2.0 Summit today, as he described his company’s retreat from the game mechanics that first made the check-in service a success. With more than 10 million downloads, Foursquare is the category leader for location services, even as it moves away from its initial offering. Crowley said Foursquare is about much more than check-ins, and features such as Foursquare Radar and Foursquare Explorer are going to power even stronger user adoption in the future.

“We have a very narrow focus on building features that help people experience the real world,” Crowley said. “How we were able to survive the Facebook onslaught — that was a big motivating factor for the entire company.”

In spite of banner user adoption, Crowley said he can identify with newcomers who are still struggling to understand why they should use a check-in service at all. Crowley said when he first downloaded Twitter, it was 18 months before he really understood why the product was worth using, because he hadn’t discovered that “thing” which made it special.

Forget consoles and PCs -- mobile gaming is prepped to be the number one gaming platform for the next decade, according to Glitch developer Tiny Speck. Vice President of Product and Operations Kakul Srivastava says we're already seeing it everywhere: "It is what is happening right now. I think the killer console is going to be your mobile device. That is absolutely where people will play more rich and involving, and even graphically intensive games."

With the newest editions of smartphones outpacing their predecessors and coming out much faster than the next console generation, Srivastava thinks it's not surprising that mobile gaming has momentum in the industry. "That pace of change is why mobile devices are going to be the console of the future. The way player interaction and player needs are changing, it's much faster than the five to seven years [of console development] that we're talking about," she said.
