Sweden’s Anyfi turns any Wi-Fi network into a small cell

Iliad’s Free Mobile is shaking up France’s wireless market with a cheap mobile data service that uses millions of residential broadband Wi-Fi access points to offload 3G traffic. Why haven’t more carriers followed Iliad’s lead? Most carriers don’t have the Iliad’s ingrained advantage: it manages both its customers’ handsets and their Wi-Fi routers.

For another mobile operator to replicate such a feat it would not only need to strike partnerships with a broadband provider or hotspot aggregator, but it would also need to implement special handset clients or wait for new technologies like Hotspot 2.0 and Next Generation Hotspot to wend their way into the market.

Swedish startup Anyfi Networks, however, has developed a technology that bypasses those steps, potentially turning any access point into an extension of a customer’s home wireless LAN. Anyfi’s technology breaks the tie between the physical radio and the Wi-Fi network, connecting your device to myriad access points and public hotspots you have never encountered before. According to co-founder and CEO Björn Smedman, Anyfi automatically spawns “virtual hotspots” that your device treats just as it would your home network.

Every device sees the totality of an operator’s ‘network,’ whether it’s the Wi-Fi embedded in its own or a partner’s residential broadband gateways, a public hotspot network or even an open access point with Anyfi’s software installed, said Smedman, co-founder and CEO. “Whenever it sees that network it will automatically connect,” Smedman said. “We’re creating virtual access points that make every Wi-Fi access point accessible to every network.”

Smedman said the technology could be used in any a number of scenarios. If a carrier is both a wireless and wireline operator like Free Mobile (or AT&T(s t) and Verizon(s vz)(s vod) in the U.S.), it can leverage its existing install base of residential gateways to link its mobile and home broadband services together. A cable operator like Time Warner (s twc) could augment its public hotspot with millions of home connections, or sell that access to a wireless operator looking to offload traffic from its 3G or 4G networks.

No software is required on the device, and the access point or residential gateway requires only a remote software update, Smedman said. Anyfi is already working with gateway maker Hitron to integrate its technology into existing products through firmware updates. If a carrier chooses to use the technology, it licenses the rights directly from Anyfi.

Consumers may not like the idea of strangers logging into their home Wi-Fi network, but Smedman said that never happens. Though the technology utilizes the physical radio in the residential gateway (which in most cases is owned by the operator) outside devices aren’t actually accessing the gateway’s secure home network. Instead, Anyfi’s software tunnels Wi-Fi authentication protocols to the device owner’s home gateway. From the device’s point of view, it’s at home. From the access point’s vantage point, it’s running two separate networks, one private and one public.

Anyfi is trialing the technology with a European and a North American operator, though he would not reveal their names. Smedman and his co-founder CTO Johan Almbladh studied applied physics together at the Lund Institute of Technology, after which they went their separate ways to work in different fields in the tech industry. The two got back together in 2009 to develop and patent Anyfi’s technology and then founded Anyfi shortly afterwards in Malmö, Sweden. The company, Smedman said, has raised “less than $1 million” in seed funding from investors and angels in Sweden.

      Oddly it looks like a direct competitor to 802.11u (“Hotspot 2.0”). Maybe that’s a good thing, gives the ISPs another option. Timing is interesting though.

  1. So, the bandwidth that I pay for at home is not for my own exclusive use? Do I get a price reduction, then? This might fly in areas that have 100-1000mbps but I’m lucky to get 10mbps in my market.

      Disclosure: I’m a co-founder of Anyfi Networks.

      It’s really up to your ISP to decide how to prioritize, but our standard configuration is that the fixed-line subscriber is always prioritized above any mobile visitors. I.e. our software will only use the spare capacity of your broadband connection that would otherwise go to waste. We take both the backhaul (what you think of as your bandwidth) and radio spectrum into account. The latter can be very important if you have “visitors” connecting from far away.

  2. I disagree that carriers can’t accomplish this unless they are also wireline providers. All they need to do is offer consumers a device and a small incentive to plug it in…then they can piggyback off the individual’s internet. I’d plug that device into my router if the carrier gave me $1/mo. per person who hit the device or something like that.

  3. Reblogged this on Nii-Teiko and commented:
    what a genius idea

    I’m actually slightly surprised that this hasn’t been implemented by more networks. actually who am I kidding?

    in fact, I’m not sure who would be best placed to actually bring this to market in the Uk. Virgin Media? Branson does like doing ‘new things’ after all

    the closest I’ve seen to this in the Uk could possibly be the promise of free wi-fi within Central London for the upcoming Olympics powered by routers in bins, old phoneboxes and discarded chicken boxes. yes, the last point is semi serious

  4. “For another mobile operator to replicate such a feat….” Well SoftBank in Japan already has. They provide open-access residential, business and hotspot femtocells in vast numbers, and have done for several years. They not only offload 100% of 3G data but they also provode a great mobile signal for voice calls. This is probably why Iliad is also a vocal supporter of femtocells with public commitment to mass depeloyment. WiFi and Cellular are complementary offload tools, now often found in the same box with the ability to be coordinated by a single policy controller.

    I work for Ubiquisys, a cellular/WiFi small cell developer.
