  Secondary & PrimaryCell Networks • A user’s primary cell network (e.g. AT&T, Verizon) can be complimented by a discount secondary network (SegundoNet) • A SegundoNet device app would periodically scan for the secondary network, and (when reachable) utilize it for voice & data at a much lower price than the primary network • SegundoNet would be built on an existing backhaul via Small Cells (Picocells)

• 3.

  Repurpose Backhaul &Frequencies • SegundoNet would use Google Fiber as its backhaul, meaning Google Fiber customer density would have to be high in any neighborhood offering SegundoNet • Picocells can be placed on houses w/ a Google Fiber connection to create a low cost cellular network w/ enough range to blanket urban areas • Unlicensed Frequencies when properly coordinated can provide cellular coverage (in some areas)

  Unlicensed Spectrum canbe plentiful • In Austin TV WhiteSpacehas 96MHz free • There is also 2.4 GHz & 5GHz & 900 MHz • Device side software-defined-radios are commonplace, devices can use these spectrums for cellular connections • Google would give Google Fiber customers customized wireless hardware that would communicate with a central service and work as a single coordinated network

• 18.

  Customized Google Wirelessboxes • Google Fiber would provide all customers with Wifi routers that would allow other customers (running the app) to use this customer’s Wifi at a reduced QoS • Wifi signals would be controlled by a Google run central service, following best Cognitive Radio practices, greatly reducing Wifi interference while increasing Wifi range • Houses selected to host Picocells would get reduced Google Fiber rates • All Picocells would communicate to a Google run central service, which would follow best Cognitive radio practices to coordinate the Picocells to avoid interference

  Primary Hardware Cost:Picocells • Spectrum is unlicensed • Backhaul already exists with Google Fiber • Picocells can be placed on the tops of houses • Software development for the system would also be a cost

  Software development costs •SegundoNet Android App development would cost some money • Development of Central Service providing Cognitive Radio software would be a significant cost • In software, getting the app, the customized wireless hardware and the Central Service to all play nicely together would be a big expense

• 21.

  App & BandwidthPrices • Android App would scan for Segundo Net and connect to it if the signal strength is strong enough and also if the device is not in a vehicle (Picocell handoffs work poorly w/ high velocity devices) • Prices would be 5-10x cheaper than competition, still enough to cover the costs of picocells and running the central service • No SIM card, just install the App & it runs as a service • SegundoNet compliments the primary network, it does not replace it (e.g. you are in a car or outside of it’s reach [e.g. on a bridge, not near a house])

• 22.

  Conclusions • A SecondaryCellular Network can be implemented at low cost to the provider (Google) that compliments a user’s primary network • Unlicensed spectrum usage and using an existing backhaul greatly reduce the setup cost for the Secondary Network • Reduced setup cost meanscell data can be offered via SegundoNet at a reduced price • Controlling communication from the device, to the cellular network, to the backhaul would give Google end to end presence

  Google Hardware inhouses • Providing customers with wifi routers and picocells opens up interesting opportunities • Optimizing network traffic would be the primary goal, but using the resources of the wifi routers &picocells as services would be an added value

  Network Device Databases •Databases can be put into both wifi routers and picocells (Network Device DBs – NDDB) • Android API calls for lazy uploads or downloads of data/files can be made that will utilize NDDBs when present • Caching data in NDDBs (think Netflix) -> WIN • Offloading downloads to Network devices can be used to lower device battery usage

• 29.

  Trusted Device forTrusted Apps • Trusted Apps can authenticate themselves to a central Google Server, afterwards they will be authorized to cache data on the NDDB • Cached data will be sandboxed per application and stored in an encrypted form • Devices using trusted apps can use NDDB as a reverse proxy cache and will need to decrypt data device-side • Can be generalized to work for any Hotspot 2.0 (802.11u) device

  Home Automation • Agoogle-box in the home that is guaranteed to be connected to the internet is a great place to house a Home Automation Gateway service • Technologies like Energy Signal Disaggregation can be used in this google-box to profile the energy usage of the appliances in the home
