    • A bootstrapping technique for wirelessly obtaining white space data that may be used to identify an available white space channel for connecting to a service. Portable wireless devices may collaborate to provide white space data to a device requesting such data. A requesting device transmits a request for the white space data using, for example, an unlicensed band. A device receiving the request may transmit a copy of the data to the requesting device. The transmitted copy may be obtained by the receiving device from a local data store or may be provided from a database server to which the receiving device is connected. In the later case the receiving device acts as a proxy between the database server and the requesting device. Once the white space data is received by the requesting device it may be used to select a channel for communication in the white space.
    • 用于无线获取可用于识别用于连接到服务的可用空白信道的空白数据的自举技术。 便携式无线设备可以协作来向请求这样的数据的设备提供空白数据。 请求设备使用例如未许可频带来发送对空白数据的请求。 接收请求的设备可以将数据的副本发送到请求设备。 发送的副本可以由接收设备从本地数据存储器获得,或者可以从接收设备连接到的数据库服务器提供。 在后一种情况下,接收设备充当数据库服务器和请求设备之间的代理。 一旦该空白数据被请求设备接收,它可以用于选择用于在空白处进行通信的信道。
