  • High increase in traffic not offseted by higher spendings (Billing tends to flat rate)
  • Depending on operator Massive costs: Spectrum – rare resource, Efficiency – software updates/new hardware Cell sites – real estate (re)Dig the world with fiber Etc.
  • Femto Cells are being used to increase in-home coverage. There are still issues with wide-scale deployment such cost and interference with the macro-network. Many smart phone users currently use their private WiFi at home, which offloads the mobile network. So the challenge is outside home, we need a wide-scale public WiFi network that will offload the network when we are outside home.
  • All the mentioned solutions so far for offloading required high costs of hardware, installing it, servicing it, etc. And the question is: Can… That would dramatically change the costs and enable a real fast network as we wish it to be. But would should the software run on?
  • We suggest the laptop be the center of the new public WiFi network. All laptops have the qualities you need from a public WiFi access point.(click) They are connected to the Internet and they have WiFi – in fact many of them are connected through a residential private WiFi. There are so many laptops that if you think about it – almost everywhere you go and want to surf with your iPhone, there is a laptop in WiFi range already connected to the Internet. We just need this laptop to send some WiFi to the iPhone.. What many people don’t know is that WiFi chipset is symmetrical and can send out WiFi like an access point even while it’s connected to another private WiFi – just like in this picture. So it’s possible and it’s working, I can show it to anyone interested I have it on my laptop here.
  • All the mentioned solutions so far for general offloading required high costs of hardware, installing it, servicing it, etc. And the question is: Can… That would dramatically change the costs and enable a real fast network as we wish it to be – or as some people like to call it disruptive. As disruptive it would raise some initial objections. But would should the software run on?
  • Operator’s incentive is clearly offloading
  • The Laptop user is fully protected through two ways: First is that only Identified users can connect to the service, and their access is authorized by a server The second is that there is a complete separation between the internet traffic of the iPhone and the Laptop’s Internet traffic.. All of the iPhone’s traffic is tunneled to the remote server The server allocates an IP address to the iPhone which is different than the IP address of the laptop. A firewall enforces all web traffic of the iPhone into the tunnel, and prevents access to the laptop by the iPhone
  • Laptop’s user experience is preserved through two paths: A bandwidth Control makes sure that iPhone does not drain too much data at any given time. Energy Consumption: Handovers: WiFi handovers are possible thanks to the tunnel (mobile-IP style)
  • Mobile Broadband usage is growing massively Costs soar Offloading is desired WiFi is a winner in offloading for data Software-Only WiFi Offloading is disruptive: ultra low cost, fast deployment It’s a win-win: Users get faster speeds, operators offload networks Secure Protects and improves user experience

  • Elad Barkan < [email_address] > , +972-54-5204123 The Future of Mobile Networks: Offloading Congested Mobile Networks with a Software-Only Approach Ver 3
  • Huge Increase in Demand for Mobile Data
    • People love the iPhone, iPad, Android, USB Modems,… and love consuming YouTube
    • The tip of the iceberg:
      • smartphones are just 14%
      • of them just 14% are iPhones
    • Increases costs:
      • AT&T Data usage up 5000% over 3 years
      • Revenue up by just 50%
    • Reduced profit
    • Weakened user experience – lower speed
  • Where are the Bottleneck ?
    • fiber-optics
    All Along the chain Core-Network Cell-Site Spectrum Backhaul x hundreds of thousand x hundreds
    • Allocate More
    • Increase Efficiency
    • More Sites to Reuse Spectrum
    • Upgrade
    x billions Internet
  • Two Current Offloading Techniques Femto-Cell WiFi Core-Network Cell-Site Backhaul Spectrum Both: In Home Not Sufficient on the roam Internet Internet
  • What if a Public WiFi Network can be Built as Simply as Installing an app ?
  • The New Access Point
    • 168M laptops shipped in 2009, installed base ~500M
    • It’s possible and working!
    • No cost -– saves $Bs
    • Blazing deployment speed
    • Complete Offload of the Mobile Network
    Public WiFi Private WiFi Internet
  • What About?
    • Laptop User Incentives
    • Security
    • User Experience
  • User Incentives
    • Get a fast Public WiFi on the roam
      • Securely share some of their unused WiFi at home
    • WiFi service is much cheaper (in a tiered-plans)
    Public WiFi Private WiFi Internet
  • Security – Laptop Fully Protected Public WiFi
    • Complete Separation:
    • iPhone’s traffic is tunneled to a remote server
    • Server allocates a unique IP Address for the iPhone
    • A firewall prevents iPhone access to the laptop – allows just tunnel
    • Access Control & Identification by server :
    • Only identified users can access
    IP Address A IP Address B Internet
  • User Experience Preserved
    • Dynamic Bandwidth Control:
    • Share 80% of unused bandwidth
    • Don’t share if all bandwidth is used by laptop
    Public WiFi IP Address A IP Address B Internet
  • Summary
    • Open Question: Can we gain anything extra given that our access point is a strong machine with large storage?
    Core-Network Cell-Site Backhaul Spectrum Public WiFi IP Address A IP Address B Internet Internet
  • Thank You
  • Questions?
  • Extra Slides
  • Bzeek Offload Solution Legality Many Internet Service Providers (ISP) contracts forbid sharing WiFi. This is mainly to stop freeloaders from getting free Internet without paying Bzeek does not allow and prevents freeloaders. User must have an existing broadband subscription to use Bzeek with their iPhone. Therefore Bzeek has positive affect on ISPs encouraging people to have Internet at home as they get faster Internet on the roam Bzeek sharing is like a consuming a special content at home – a content that gives you fast WiFi when you roam. It’s like moving some of your unused bandwidth at home to be used where the user is roaming Forbidding this content service would be interfering with net neutrality – it’s similar to Skype that uses idle bandwidth to relay calls of other users
  • Compared to Femto
    • Femtocells a great solution to supplement voice coverage
    • Less advantageous where it comes to data
    FemtoCells Offloading Software WiFi Offloading Over $100 $0 Hardware cost + + Data Offload from macro network - might increase load due to handovers + Core network offload - Interferes with operator’s spectrum and cell planning + WiFi uses a separate spectrum Spectral Offloading
  • Competitive Analysis – Femto FemtoCells Offloading Bzeek Offloading Requires: available ethernet port, power plug, connect wires just a PC Installation requirements + Only within WiFi Continuity of service - Hardware may fail, require maintenance at user premises + Automatic Upgrades Low maintenance
